18. Reverse Fan Switch

(Only Use for DX420, 480, 520LC)

This switch is used to clean the front of the radiator by

blowing air out from the engine compartment.

O. In this position, the radiator fan motor draws air into

the engine compartment.

I.

In this position, the radiator fan motor blows air out

from the engine compartment.

NOTE: When working in areas where debris can build

FG016027

up quickly on radiator it is advised to reverse the

Figure 28

fan every fifteen minutes.

NOTE: Pay attention to the engine coolant temperature

gauge. A sudden rise in temperature is an

indicator that the fan may need to be reversed

to clean radiator.

WARNING

There should be no personnel in front of the fan when

it is reversed, to keep them from being injured from

flying materials.

IMPORTANT

1.

Set safety lever on "LOCK" position.

2.

Set reverse fan switch on "I" (ON) position.

19. Overload Warning Switch (Optional)

O

If unit is equipped with an overload warning device, push

this switch to activate it.

WARNING

To prevent injury, do not exceed the rated load

capacity of the machine. If the machine is not on level

ground, load capacities will vary. There may be local

government regulations about the use of excavators

for lifting objects.

Please observe these regulations.

During operation, the pointer must be in the blue zone.

If the gauge pointer moves into the red zone, the engine

coolant temperature warning light will turn "ON," a warning

buzzer will sound, and the engine speed will be

automatically reduced. Allow the engine to run at low idle

speed until temperature gauge registers in the blue zone

again. When the blue zone is reached, allow the engine to

idle for an additional three - five minutes before shutting

down the engine. If not allowed to idle, heat surge may

develop which will damage the engine. Allowing the engine

to idle will dissipate heat. Check the coolant level, look for

a loose fan belt, inspect for debris around radiator, and so

on.

When the temperature reaches the normal range, the

engine speed will automatically recover.

Engine Coolant Temperature Warning

If engine coolant overheats, this symbol appears on the

screen an alarm will sound, and the engine speed will be

automatically reduced, until coolant temperature drops. Do

not turn engine "OFF" because this will cause coolant

temperature to rise and may cause engine to siege

because of heat surge.

the gauge pointer moves into the red zone, the

engine coolant temperature warning light will

engine speed will be automatically reduced.

Allow the engine to run at low idle speed until

temperature gauge registers in the blue zone

engine to idle for an additional three

- five

minutes before shutting down the engine. If not

allowed to idle, heat surge may develop which

will damage the engine. Allowing the engine to

abdomen.

Under no circumstances should the operator be

standing in the cabin when operating the excavator.

Do not adjust the seat position while the vehicle is

moving because a loss of control may result. Stop the

SAFETY LEVER

WARNING

When stopping engine or leaving the operator's seat,

"LOCK" the safety lever, otherwise, a serious accident may

occur by accidental movement of travel and work levers.

Whenever leaving the operator's seat, make sure the engine

is shut down and the safety lever is "LOCKED."

Especially, when adjusting the seat, control stands, or

raising the front window, lower window, or ceiling cover,

never forget to lock the safety lever in its "LOCKED"

position.

Be careful not to move the work levers (joysticks) when moving

safety lever.

1.

Push safety lever (Figure 25) down into the "LOCKED"

position. When safety lever is in the "LOCKED" position,

the front attachment, swing and travel movement will be

disabled even though a lever is moved.

NOTE: Lower bucket

(front attachment) to ground.

Place all control levers in "NEUTRAL" and shut

down engine, before using the safety lever.

NOTE: When the engine is not running, but the safety

lever is "RELEASED" and the starter key is

TRAVEL

WARNING

1.

Before operating the travel levers, make sure that you

know in which direction the machine is pointing. Look at

the end of the track assemblies. If the drive motors are

visible while sitting in the operator's seat, you are

looking at the back end of the track assembly (therefore,

you are looking backwards). In this case, the response of

the travel levers will be the reverse of normal operation.

2.

Before moving, make sure that there are no personnel

in the way or on the machine. Sound the horn to alert

workers that you are about to move the machine.

3.

Be sure the path is clear during travel.

4.

Use extreme caution when reversing travel. Be sure

there is a clear path behind the machine.

5.

Make sure to operate the travel control levers

smoothly to avoid sudden starts or stops.

6.

Before leaving the operator's seat, make sure to lock

out all control systems and shut down the engine to

avoid accidental activation.

Automatic Travel Speed Control

WARNING

Do not change the travel mode while traveling. Always use

speed mode "O" when traveling down a slope. It is very

dangerous to change to speed modes indicated "I" or "II"

while going down a slope. Only change travel mode after

coming to a complete stop.

Two travel speed ranges can be selected by using the travel

speed selector switch on the control panel (Figure 26).

O

"O" (LOW) - In this position low travel speed and a higher torque

I

are selected.

II

"I" (HIGH) - In this position high travel speed and a lower torque

are selected.

"II"

(AUTOMATIC) - Setting the control at the "II" position

enables the machine to change to a different speed range

automatically. This change happens automatically depending on

the hydraulic oil pressure in the travel circuit. When hydraulic oil

FG016016

pressure rises, the travel speed is automatically set to low. An

Figure 26

example is if the machine is traveling on a flat, solid surface, the

higher speed range would be used. When a slope is

encountered, the speed drops and the travel circuit hydraulic

pressure rises, causing the control circuit to shift to the higher

torque, lower speed range.

When possible, travel on firm, level ground. Avoid sudden

movements and sharp turns.

4.

When traveling on rough ground, travel at a slow speed

[1.0 - 1.5 km/h (0.62 - 0.93 MPH)]. Reduced engine speed,

to avoid shock loading the equipment. Be careful that an

excessive force is not added to equipment by touching or

climbing on rocks.

Figure 33

Operation

OP001173

5.

On rough, frozen or uneven terrain, travel slowly.

WARNING

When traveling, keep bucket from 20 - 30 cm (8 - 12 in)

above ground.

Do not travel backward on a slope.

Never turn or travel crosswise on a slope.

Choose a safe alternate route before climbing a slope.

FG000212

If excavator starts to slip or becomes unstable, lower

Figure 34

the bucket immediately into the ground, using it as a

brake.

Avoid working on slopes, because there is a danger of

overturning by becoming unbalance while swinging

and performing front attachment operations.

It is very dangerous to swing towards bottom of slope

with a loaded bucket.

In unavoidable cases level the slope with fill soil, to

make the vehicle as horizontal as possible. See Figure

34.

Do not travel on slopes more than 30° because of

FG000126

turnover danger.

Figure 35

6.

Travel straight up or down slopes, never diagonally across

the slope. See Figure 35 and Figure 36. Extend the arm

and lower the boom to keep the bucket about 20 - 30 cm (8

-

12 in) off the ground. If the machine starts to slide or

becomes unstable, lower the bucket to regain control. If the

engine stalls, lower the bucket, make sure that all controls

are in the neutral position and restart the engine.

NOTE: Even though engine stops on a slope, do not

operate swing control. The hydraulic

accumulators may cause the unit to swing.

FG000128

NOTE: Do not open or close operator's door on a slope.

Figure 36

Make sure door is latched.

If dirt or mud builds up in the track frame, raise each track

and rotate and clean that track.

CAUTION

When using the boom and arm to lift any portion of the

machine, roll the bucket until round base is against the

ground. The angle of the arm to the boom should be at

90°.
