SUMMARY OF SAFETY

PRECAUTIONS FOR LIFTING IN

DIGGING MODE

DANGER

Unsafe use of the excavator while making rated lifts could

cause serious, potentially fatal injuries or extensive damage

to the machine or nearby property. Do not let anyone

operate the machine unless they've been properly trained

and understand the information in the Operation and

Maintenance Manual.

To lift safely while in Digging Mode, the following items must be

evaluated by the operator and the work site crew.

•

Condition of ground support.

•

Excavator configuration and attachments.

•

Weight, lifting height and lifting radius.

•

Safe rigging of the load.

•

Proper handling of the suspended load.

Tag lines on opposite sides of the load can be very helpful in

keeping a suspended load secure, if they are anchored safely to

control points on the ground.

WARNING

NEVER wrap a tag line around your hands or body.

NEVER rely on tag lines or make rated lifts when wind gusts

are more than 48.3 km/h (30 MPH). Be prepared for any wind

gust when working with loads that have a large surface

area.

Always engage the "Digging Mode" control on the Instrument

Panel before using the excavator for lifting work.

WARNING

If you need more information or have any questions or

concerns about safe operating procedures or working the

Fuel, Oil and Hydraulic Fluid Fire Hazards

Fuel, oil and antifreeze will catch fire if it is brought close to a

flame. Fuel is particularly flammable and can be hazardous.

Always strictly observe the following.

Add fuel, oil, antifreeze and hydraulic fluid to the machine only in

a well ventilated area. The machine must be parked with

controls, lights and switches turned "OFF." The engine must be

"OFF" and any flames, glowing embers, auxiliary heating units

or spark causing equipment must be extinguished, turned "OFF"

and/or kept well clear of the machine.

Static electricity can produce dangerous sparks at the fuel filling

nozzle. In very cold, dry weather or other conditions that could

produce a static discharge, keep the tip of the fuel nozzle in

constant contact with the neck of the fuel filling nozzle, to

Figure 4

provide a ground.

Keep fuel and other fluid reservoir caps tight and do not start the

engine until caps have been secured.

Precautions When Handling Fluids at High

Temperature

Immediately after operations are stopped, the coolant, engine

oil, and hydraulic oil are at highest temperatures and the radiator

and hydraulic tank are still under pressure. Attempting to

remove cap, drain the oil or coolant, or replace the filters may

lead to serious burns. Always wait for the temperature to go

down, and follow the specified procedures when carrying out

these operations.

site and working environment.

Injury from Work Equipment

Do not enter or put your hand, arm or any other part of your body

between movable parts, such as between the work equipment

and cylinders, or between the machine and work equipment.

If the control levers are operated, the clearance between the

machine and the work equipment will change and this may lead

to serious damage or personal injury.

If going between movable parts is necessary, always position

and secure the work equipment so it cannot move.

HDO1010L

Figure 8

Fire Extinguisher and First Aid Kit

As a precaution if any injury or fire should occur, always do the

following.

•

Be sure that fire extinguishers have been provided

and read the labels to ensure that you know how to

use them. It is recommended that an appropriately

sized (2.27 kg [5 lb] or larger) multipurpose "A/B/C"

fire extinguisher be mounted in the cabin. Check and

service the fire extinguisher at regular intervals and

make sure that all work site crew members are

HDO1009L

adequately trained in its use.

Figure 9

•

Provide a first aid kit in the storage compartment and

keep another at the work site. Check the kit

periodically and make any additions if necessary.

•

Know what to do in case of injury from fire.

•

Keep emergency numbers for doctor, ambulance

service, hospital and fire department near your

telephone.

Safety

OP001002

1-19

If the machine catches fire, it may lead to serious personal injury

or death. If a fire occurs during operation, escape from the

machine as follows:

•

Turn the starter switch to the "O" (OFF) position and

shut down engine.

•

If there is time, use the fire extinguisher to put out as

much of the fire as possible.

•

Use the handrails and steps to escape from the

machine.

The above is the basic method for escaping from the machine,

but changing the method may be necessary according to the

conditions, so carry out practice drills at the work site.

Protection from Falling or Flying Objects

On work sites where there is a danger that falling or flying

objects may hit the operator's cabin select a guard to match the

operating conditions to protect the operator.

Working in mines, tunnels, deep pits or on loose or wet surfaces

could produce danger of falling rock or hazardous flying objects.

Additional protection for the operator's cabin could be required in

the form of a FOPS (Falling Object Protective Structure) or

window guards.

HAOA110L

Figure 10

Never attempt to alter or modify any protective structure

reinforcement system, by drilling holes, welding, remounting or

relocating fasteners. Any serious impact or damage to the

system requires a complete integrity reevaluation.

Reinstallation, recertification and/or replacement of the system

may be necessary.

Contact your DOOSAN distributor for available safety guards

and/or recommendations to prevent danger of getting hit by

objects that could strike the operator's cabin. Make sure that all

other work site crew members are kept well away from the

excavator and safe from possible hazards.

HAOA100L

Figure 11

For breaker operation, install a front guard and apply a

laminated coating sheet to the front glass. Contact your

DOOSAN distributor for recommendations.

Attachment Precautions

Option kits are available through your dealer. Contact DOOSAN

for information on available one-way (single-acting) and two-way

(double-acting) piping / valving / auxiliary control kits. Because

DOOSAN cannot anticipate, identify or test all the attachments

that owners may wish to install on their machines, please

contact DOOSAN for authorization and approval of attachments,

and their compatibility with optional kits.

Accumulator

The pilot control system is equipped with an accumulator. For a

brief period of time after the engine has been shut down, the

accumulator will store a pressure charge that may enable

hydraulic controls to be activated. Activation of any controls may

enable the selected function to operate under force of gravity.

When performing maintenance on the pilot control system, the

hydraulic pressure in the system must be released as described

in “Handling of Accumulator” on page 4-80.

The accumulator is charged with high-pressure nitrogen gas, so

it is extremely dangerous if it is handled in the wrong way.

Always observe the following precautions:

•

Do not drill or make any holes in the accumulator or

expose it to any flames, fire or heat source.

•

Do not weld on the accumulator, or try attaching

anything to it.

•

When carrying out disassembly or maintenance of

the accumulator, or when disposing of the

accumulator, the charged gas must be properly

released. Contact your DOOSAN distributor.

•

Wear safety goggles and protective gloves when

working on an accumulator. Hydraulic oil under

pressure can penetrate the skin and cause serious

injuries.

Indoor Ventilation

Engine exhaust gases can cause fatal accidents, and

unconsciousness, loss of alertness, judgment and motor control

and serious injury.

Make sure there is adequate ventilation before starting the

engine in any enclosed area.

You should also be aware of open windows, doors or ductwork

where exhaust may be carried, or blown by the wind, exposing

others to danger.

identify their locations. Be careful not to damage or cut any of

these lines.

Check the condition of the riverbed, and the depth and flow of

the water before operating in water or crossing a river. NEVER

work in water that is more than the permissible water depth.

Any object in vicinity of boom could represent a potential hazard,

or cause the operator to react suddenly and cause an accident.

Use a spotter or signal person when working near bridges,

FG000363

phone lines, work site scaffolds, or other obstructions.

Minimum levels of insurance coverage, work permits or

certification, physical barriers around the work site or restricted

hours of operation may be mandated by governing authorities.

There may also be regulations, guidelines, standards or

restrictions on equipment that may have to be followed for local

requirements. There may also be regulations related to

performing certain kinds of work. If there is any question about

whether your machine and work site complies with the

applicable standards and regulations, contact your local

authorities and agencies.

Avoid entering soft ground. It will be difficult for the machine to

escape.

FG000372

Figure 16

Avoid operating your machine to close to the edge of cliffs,

overhangs, and deep ditches. The ground may be weak in such

areas. If the ground collapses, the machine could fall or tip over

resulting in serious injury or death.

Remember that soil after heavy rain, blasting or after

earthquakes, is weakened.

Newly laid earth and the soil near ditches is typically loose. It

can collapse under the weight of vibration of your machine and

cause your machine to tip over.

Install the head guard (FOPS) if working in areas where there is

a danger of falling rocks.

Checks Before Starting Engine

Every day before starting the engine for the first time, carry out

the following checks. If these checks are not carried out

properly, there is a danger of serious injury.

Remove all wood chips, leaves, grass, paper and other

flammable materials accumulated in the engine compartment

and around the battery. They could cause a fire. Remove any

dirt from the window glass, mirrors, handrails, and steps.

Do not leave tools or spare parts laying around in the operator's

cabin. The vibration of the machine when traveling or during

operations may cause them to fall and damage or break the

control levers or switches. They may also get caught in the gap

of the control levers and cause the work equipment to

malfunction or move dangerously. This may lead to unexpected

accidents.

Check the coolant, fuel, and hydraulic tank oil levels, and check

for clogged air cleaner and damage to the electrical wiring.

Adjust the operator's seat to a position where it is easy to

operate the machine, and check the seat belt and mounts for

damage and wear.

Check the operation of the gauges and the angle of the mirrors,

and check that safety lever is in "LOCKED" position.

If any abnormalities are found in the above checks, carry out

repairs immediately.

Safety

OP001002

1-24

Engine Starting

Walk around your machine before getting in the operator's

cabin. Look for evidence of leaking fluid, loose fasteners,

misaligned assemblies or any other indications of possible

equipment hazard.

All equipment covers and machinery safety guards must be in

place, to protect against injury while the machine is being

operated.

Look around the work site area for potential hazards, people or

property that could be at risk while operation is in progress.

NEVER start the engine if there is any indication that

maintenance or service work is in progress, or if a warning tag is

attached to controls in the cabin.

A machine that has not been used recently, or is being operated

in extremely cold temperatures, could require a warm-up or

maintenance service before start-up.

Check gauges and monitor displays for normal operation before

starting the engine. Listen for unusual noises and remain alert

for other potentially hazardous conditions at the start of the work

cycle.

Do not short-circuit the starting motor to start the engine. This is

not only dangerous, but may also damage the machine.

When starting the engine, sound the horn as an alert.

Start and operate the machine only while seated.

Safety

1-25

Before Operating Machine

If checks are not carried out properly after starting the engine, it

may result in a delay in discovering abnormalities in the

machine, and this may lead to personal injury or damage to the

machine.

Carry out the checks in an open area where there are no

obstructions. Do not let anyone near the machine when carrying

out the checks.

•

Check the operating condition of the equipment, and

the movement of the bucket, arm, boom, travel, and

swing systems.

•

Check the machine for any abnormal noise, vibration,

heat, smell, or abnormality with the gauges. Check

also for leakage of air, oil, and fuel.

•

If any abnormality is found, repair the problem

immediately. If the machine is used without repairing

the problems, it may lead to unexpected injury or

failure.

•

Clear all personnel from directly around machine and

from the area.

•

Clear all obstacles from the machine's path. Beware

of hazards.

•

Be sure that all windows are clean. Secure the doors

and the windows in the open position or in the shut

position.

•

Adjust the rearview mirrors for best visibility close to

the machine. Make sure that horn, the travel alarm (if

equipped), and all other warning devices are working

properly.

•

Fasten the seat belt securely.

•

Warm up the engine and hydraulic oil before

operating machine.

•

Before moving the machine, check undercarriage

position. The normal travel position is with idler

wheels to the front under the cabin and the drive

sprockets to the rear. When the undercarriage is in

the reversed position, the travel controls must be

operated in opposite directions.

MACHINE OPERATION

When Swinging or Changing Direction of

Travel

Before operating the machine or the work equipment, always

observe the following precautions to prevent serious injury or

death.

•

Start and operate the machine only while seated.

•

When changing travel direction from forward to

reverse or from reverse to forward, reduce speed

early and stop the machine before changing the

HAOA190L

travel direction.

Figure 17

•

Sound the horn to warn people in the area.

•

Check that there is no one in the area around the

machine. There are blind spots behind the machine,

so if necessary, swing the upper structure to check

that there is no one behind the machine before

traveling in reverse.

•

When operating in areas that may be hazardous or

have poor visibility, designate a person to direct work

site traffic.

•

Ensure that no unauthorized person can come within

the turning radius or direction of travel.

Be sure to observe the above precautions even if a travel alarm

or mirrors are installed.

Travel Precautions

TRAVEL POSTURE

Never turn the starting switch to the "O" (OFF) position when

traveling. It is dangerous if the engine stops while the machine is

traveling. It will be impossible to operate the steering.

Attachment control levers should not be operated while

traveling.

Do not change selected travel mode

(FAST/SLOW) while

traveling.

40 ~ 50 cm (16 ~ 20 in.)

Fold in work equipment so the outer end of the boom is as close

to the machine as possible, and is 40 - 50 cm (16 - 20 in)

aboveground.

INCORRECT

Never travel over obstacles or slopes that will cause the

machine to tilt severely. Travel around any slope or obstacle that

causes the machine to tilt 10 degrees or more to the right or left,

or 30 degrees or more from front to rear.

Do not operate the steering suddenly. The work equipment may

hit the ground and cause the machine to lose its balance, and

this may damage the machine or structures in the area.

When traveling on rough ground, travel at low speed, and avoid

FG000349

sudden changes in direction.

Figure 18

Always keep to the permissible water depth. Permissible water

depth is to the centerline of the upper track rollers.

When traveling over bridges or structures on private land, check

first that bridge or structure can withstand the weight of the

machine. When traveling on public roads, check with the local

authorities and follow their instructions.

Safety

OP001002

1-28

Traveling on Slopes

Never jump onto a machine that is running away to stop it. There

is a danger of serious injury.

Traveling on slopes could result in the machine tipping over or

slipping.

On hills, banks or slopes, carry the bucket approximately 20 - 30

cm (8 - 12 in) above the ground. In case of an emergency,

quickly lower the bucket to the ground to help stop the machine.

Do not travel on grass, fallen leaves, or wet steel plates. Even

slight slopes may cause the machine to slip to the side, so travel

at low speed and make sure that machine is always traveling

directly up or down the slope.

Avoid changing travel direction on a slope. This could result in

tipping or sideslipping of the machine.

When possible, operate the machine up slopes and downslopes.

Avoid operating the machine across the slope, when possible.

FG000365

Figure 19

Prohibited Operations

Do not dig the work face under an overhang. This may cause the

overhang to collapse and fall on top of the machine.

FG000368

Figure 20

Do not carry out deep digging under the front of the machine.

The ground under the machine may collapse and cause the

machine to fall.

Working heavy loads over loose, soft ground or uneven, broken

terrain can cause dangerous side load conditions and possible

tip over and injury. Travel without a load or a balanced load may

also be hazardous.

Never rely on lift jacks or other inadequate supports when work

is being done. Block tracks fore and aft to prevent any

movement.

FG000170

Figure 21

When using the machine, to prevent accidents caused by

damage to the work equipment and overturning because of an

excessive load, do not use the machine in excess of its ability (in

terms of the maximum load and stability determined by the

structure of the machine).

When working at the edge of an excavation or on a road

shoulder, the machine could tip over, possibly resulting in

serious injury or death. Investigate the configuration and ground

conditions of the work site beforehand to prevent the machine

from falling and to prevent the ground, stockpiles, or banks from

collapsing.

Precautions for Operation

Be careful not to mistakenly travel too close to the edge of a cliff.

Use the machine only for its main purpose. Using it for other

purposes will cause failures.

To ensure a good view, always do the following:

•

When working in dark areas, attach working lights

and front lights to the machine. If necessary, set up

lighting at the work site.

•

Stop operations when the visibility is poor, such as in

fog, mist, snow, and rain. Wait for the visibility to

improve to a level which causes no problems for the

operation.

To avoid hitting the work equipment, always do the following:

•

When working in tunnels, on bridges, under electrical

wires, or when parking the machine or carrying out

other operations in places with limited height, be

careful not to hit the bucket or other parts.

•

To prevent collisions, operate the machine at a safe

speed when working in confined spaces, indoors, or

in crowded areas.

•

Do not pass the bucket over the heads of workers or

over the operator's cabin of dump truck.

FG000430

Figure 23

Avoid High-Voltage Cables

Serious injury or death can result from contact or proximity to

high-voltage electrical lines. The bucket does not have to make

physical contact with power lines for current to be transmitted.

Use a spotter and hand signals to stay away from power lines

not clearly visible to the operator.

Use these minimum distances as a guideline only. Depending

upon the voltage in the line and atmospheric conditions, strong

current shocks can occur with the boom or bucket as faraway as

4 - 6 m (13 - 20 ft.) from the power line. Very high voltage and

rainy weather could further decrease that safety margin.

NOTE: Before starting any operation near power lines (either

aboveground or buried cable type), you should

always contact the power utility company directly and

work out a safety plan with them.

Safety

OP001002

1-31

Protecting Cabin from Falling Object

(Optional)

In a work site where falling objects or flying objects are

expected, be sure to install adequate protective devices for

covering the cabin.

When using a breaker, be sure to install the front window

protection guard (Figure 25).

FG000112

Figure 25

In a work site where falling rocks can cause damage and

possibly crush personnel, or in a mining operation, be sure to

install the falling object protective structure (Figure 26).

Be sure to install any other additional protective structures

required for work site conditions.

When the falling object protective structure is installed, and the

front window needs to be cleaned, loosen the bolts marked with

an arrow. Be sure to tighten bolts when done.

Operate Carefully on Snow, Ice and in Very

Cold Temperatures

In icy cold weather avoid sudden travel movements and stay

away from even slight slopes. The machine could skid off to one

side very easily.

Snow accumulation could hide or obscure potential hazards.

Use care while operating or while using the machine to clear

FG000113

snow.

Figure 26

Warming up the engine for a short period may be necessary, to

avoid operating with sluggish or reduced working capacity. The

jolting shocks and impact loads caused by bumping or

bottoming the boom or attachment are more likely to cause

severe stress in very cold temperatures. Reducing work cycle

rate and workload may be necessary.

When the temperature rises, frozen road surfaces become soft,

and machine travel becomes unstable.

In cold weather, do not touch metal surfaces with your bare

hands. If you touch a metal surface in extremely cold weather,

your skin may freeze to the metal surface.

Safety

OP001002

Operations on Slopes

When working on slopes. there is a danger that machine may

lose its balance and turn over, when swinging, or when work

equipment is operated. Always carry out these operations

carefully.

Do not swing the work equipment from the uphill side to the

downhill side when the bucket is loaded. This operation is

dangerous.

If the machine has to be used on a slope, pile the soil to make a

FG000212

platform that will keep the machine as horizontal as possible.

Figure 27

In addition, lower the bucket as far as possible, keep it pulled

into the front, and keep the swing speed as low as possible.

Parking Machine

Avoid making sudden stops, or parking the machine wherever it

happens to be at the end of the workday. Plan so the excavator

120

will be on firm, level ground away from traffic and away from

high walls, cliff edges and any area of potential water

accumulation or runoff. If parking on inclines is unavoidable,

Block

block the crawler tracks to prevent movement. Lower the bucket

or other working attachment completely to the ground, or to an

overnight support saddle. There should be no possibility of

unintended or accidental movement.

When parking on public roads, provide fences, signs, flags, or

Unlock

lights, and put up any other necessary signs to ensure that

passing traffic can see the machine clearly. Park the machine so

the machine, flags, and fences do not obstruct traffic.

After the front attachment has been lowered to an overnight

storage position and all switches and operating controls are in

Lock

FG000666

the "OFF" position, the safety lock lever must be set to the

Figure 28

"LOCKED" position. This will disable all pilot circuit control

functions.

Always close the door of the operator's cabin.

Never Let Anyone Ride on Attachment

Never let anyone ride on any work attachment, such as the

bucket, crusher, grapple, or clamshell (grab bucket). There is a

danger of the person falling and suffering serious injury.

Clean Before Inspection or Maintenance

Clean the machine before carrying out inspection and

maintenance. This prevents dirt from getting into the machine

and ensures safety during maintenance.

If inspection and maintenance are carried out when the machine

is dirty, it will become more difficult to locate the problems, and

there is a danger that you may get dirt or mud in your eyes or

that you may slip and injure yourself.

When washing the machine, do the following:

•

Wear shoes with nonslip soles to prevent yourself

from slipping and falling on wet places.

•

Wear safety glasses and protective clothing when

washing the machine with high-pressure steam.

•

Take action to prevent touching high-pressure water

and cutting your skin or having mud fly into your

Burn Prevention

When checking the radiator coolant level, shut down engine, let

the engine and radiator cool down, then check the coolant

recovery tank. If the coolant level in the coolant recovery tank is

near the upper limit, there is enough coolant in the radiator.

Loosen the radiator cap gradually to release the internal

pressure before removing the radiator cap.

If the coolant level in the coolant recovery tank is below the

lower limit, add coolant.

Cooling system conditioner contains alkali. Alkali can cause

personal injury. Do not allow alkali to contact the skin, the eyes,

or the mouth.

Allow cooling system components to cool before you drain the

cooling system.

Hot oil and hot components can cause personal injury. Do not

allow hot oil or hot components to contact the skin.

Remove hydraulic tank filter plug only after the engine has been

stopped. Make sure that hydraulic tank filter plug is cool before

you remove it with your bare hand. Remove hydraulic tank filter

plug slowly to relieve pressure.

Relieve all pressure in the hydraulic oil system, in the fuel

system, or in the cooling system before you disconnect any

lines, fittings, or related items.

Welding Repairs

When carrying out welding repairs, carry out the welding in a

properly equipped place. The welding should be performed by a

qualified worker. During welding operations, there is the danger

of, generation of gas, fire, or electric shock, so never let an

unqualified worker do welding.

The qualified welder must do the following:

•

To prevent explosion of the battery, disconnect the

battery terminals and remove batteries.

•

To prevent generation of gas, remove paint from the

location of the weld.

•

If hydraulic equipment, piping or places close to them

are heated, a flammable gas or mist will be generated

and there is a danger of it catching fire. To avoid this,

never subject these places to heat.

•

Do not weld on pipes or on tubes that contain

flammable fluids. Do not flame cut on pipes or on

tubes that contain flammable fluids. Before you weld

on pipes or on tubes or before you flame cut on pipes

or on tubes, clean the pipes or tubes thoroughly with

a nonflammable solvent.

Prevention of Crushing and Cutting

You should always have at least two people working together if

the engine must be run during service. One person needs to

remain in the operator's seat, ready to work the controls or stop

the machine and shut off the engine.

Unless you are instructed otherwise, never attempt adjustments

while the machine is moving or while the engine is running.

Stay clear of all rotating parts and moving parts.

Keep objects away from moving fan blades. The fan blades will

throw objects and the fan blades can cut objects.

Do not use a wire rope cable that is kinked or frayed. Wear

gloves when you handle a wire rope cable.

When you strike a retainer pin, the retainer pin might fly out. The

loose retainer pin can injure personnel. Make sure that area is

clear of people when you strike a retainer pin. To avoid injury to

your eyes, wear protective glasses when you strike a retainer

pin.

Track Tension Adjustments Require

Caution

Never turn out the track tension grease valve. To release

pressure from the crawler frame track tension assembly, you

TOWING

Precautions When Towing

Cloth

If any mistake is made in the method of selecting or inspecting

the towing wire or in the method of towing, it may lead to serious

personal injury. Always do the following:

•

Always use the method of towing given in this

Operation and Maintenance Manual. Do not use any

other method.

Towing Wire

•

Use leather gloves when handling the wire rope.

•

When carrying out the preparation work for towing

with two or more workers, determine the signals to

use and follow these signals correctly.

•

Always fit the towing rope to the left and right hooks

and secure in position.

•

If the engine on the problem machine will not start or

there is a failure in the brake system. always contact

your DOOSAN distributor.

Towing Wire

•

Never go between the towing machine and the towed

FG014871

machine during the towing operation.

Figure 45

•

It is dangerous to carry out towing on slopes, so

select a place where the slope is gradual. If there is

no place where the slope is gradual, carry out

operations to reduce the angle of the slope before

starting the towing operation.

•

When towing a problem machine, always use a wire

rope with a sufficient towing capacity.

•

Do not use a frayed, kinked rope or a rope with any

loss of diameter.

•

Do not use the lightweight towing hook for towing

another machine.

EXCAVATOR RATED LIFT

CAPACITY TABLES

WARNING

Let everybody be away from the boom cylinder. While lifting

operation, boom, arm, bucket hoses might burst and then

high-pressure oil will be ejected at high-speed.

If that failure mode takes place, handling weight or front

structure might fall by its gravity to the ground to cause

fatal injury to the person.

When changing the hoses record the part numbers of the

hoses to factory log book.

Do the service job under the company's serviceman.

Figure 46

WARNING

All rated lift capacities are based on the machine and the

load both remaining level at all times. DO NOT EXCEED THE

RATED LIFT CAPACITY. Lifting loads greater than those

shown in the rated capacity tables can cause catastrophic

equipment failure and/or structural collapse of the machine.

To operate safely the excavator should be on a firm, level and

uniformly supporting surface. The operator is expected to make

due allowance for all specific work site and lift related conditions,

and respond to changes in those conditions that could pose a

hazard. The following could all cause hazardous conditions and

accidents or injuries:

•

Soft or uneven ground.

•

Unlevel terrain.

•

Side loads.

•

Modifications or poor maintenance of the excavator.

•

Failure to lift squarely over the end or over the side of

the machine.

When a load is in the air, the operator must remain alert.

•

Avoid side loads that may be caused by uneven

slings, traveling with the load or swinging too quickly.

•

The load can become unbalanced if the hook line is

twisted and starts to rotate. If the surface area of the

load is large enough, wind gusts can create side loads.

•

Keep the bucket hook point directly over the load.

Tag lines on opposite sides of the load can help

maintain greater stability against side loads and wind gusts.

Safety

OP001002

1-46

Avoid traveling with a suspended load. Before swinging (or if

required, traveling), bring the load into an arm position (radius

and height) that has a safer weight capacity rating and adequate

movement clearance. The operator and all work site personnel

should be thoroughly familiar with safety instructions and

procedures within this Operation and Maintenance Manual.

The following weight loads are in compliance with SAE (J1097)

and ISO applicable, recommended standards for hydraulic

excavators performing lifting operation on a firm supporting

surface. An asterisk (*) next to the lift rating indicates rated load

does not exceed 87% of hydraulic capacity. All other ratings

have been determined not to exceed 75% of tipping capacity.

Do not attempt to lift or hold any load that exceeds rated load

capacity at the specified distances (from the machine's rotation

centerline and height - see "lift radius" and "lift height" in the

reference drawing, Figure 47).

Figure 47

The weight of slings and any auxiliary lifting device (and/or the

weight difference of any attachment heavier than standard

configuration) must be deducted from the rated lift capacity to

determine allowable net lifting load. The lift point should be on

the back of the bucket, as shown in Figure 47.

IMPORTANT

Select the Digging Mode switch on the Instrument Panel

before using the excavator for lifting work. Engine and

hydraulic oil should both be fully warmed up to operating

temperature before starting a lift.

Starter Switch

A three-position starter switch is used to start or shut down

engine for equipment operation.

O. Turning the switch to this position turns the engine

"OFF" along with its electrical system. In this position

the engine is "OFF" but the interior cabin light and

fuel tank transfer pump (if equipped) are functional.

Turning the switch to this position turns the engine

electrical system "ON." When the switch is first turned

FG000014

"ON" the six indicator/warning lights across the top of

Figure 4

the instrument panel, will light for approximately two

seconds. The battery warning light and the engine oil

pressure warning light should remain "ON" after the

other four have turned "OFF."

NOTE: Preheat Indicator Light - The operation of

the preheat cycle depends on coolant

temperature. When the engine coolant is

cold enough, the preheat indicator light will

remain "ON" until the engine preheat cycle

is completed. The preheat cycle takes

about twenty seconds to complete, and

the indicator light will turn "OFF." When

the light turns "OFF," engage the starter.

. Moving switch to this position will crank engine. When

engine starts, release key and allow it to return to the

"I" (ON) position. Do not operate the starter switch for

more than fifteen seconds at a time. This will help

prevent damage to starter.

WARNING

DO NOT USE STARTING FLUIDS. The preheat system

could cause the starting fluid to explode. Starting

fluids should never be used.

2. Engine Speed Control Dial

The engine speed is controlled by the dial. Rotating it

clockwise increases engine speed

B High idle (Highest engine speed)

NOTE: The auto idle system will automatically reduce

engine speed to idle speed approximately four

seconds after all of the control levers are in the

HAOA690L

neutral position. This system is designed to
