Starter Switch

O

I

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.

I.

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

(rpm) and

counterclockwise decreases engine speed.

A. Low idle (Lowest 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

Figure 5

reduce fuel consumption and noise. See “3.

Auto Idle Selector Button” on page 2-39.

I

O. In this position

, the quick clamp is "LOCKED." The

attachment is secured to the arm.

I.

In this position

, the quick clamp is "UNLOCKED."

The attachment is released from the arm.

NOTE: To move the switch, pull up on the toggle

and then move it into the "UNLOCKED"

FG001342

position.

Figure 6

WARNING!

When the attachment is still connected to the machine,

while the switch is "I" (

) position, do not operate the

machine or the attachment might fall to the ground. It

would cause personnel injuries.

4. Auxiliary Mode Switch

O

I

When the control system is out of order, the pump system

can be controlled manually.

O. In this position, the manual pump control is "OFF."

I.

In this position, the manual pump control is "ON."

CAUTION!

FG001343

Be sure to turn pump control to the "O" (OFF) position,

Figure 7

after the control system is operating properly.

5. Engine Emergency Stop Switch

O I

If the engine does not shut down when using the starter

switch, it can be stopped by moving the engine emergency

stop switch to the "I" (EMERGENCY STOP) position.

O. In this position, the engine emergency stop system is

"OFF."

I.

In this position, "EMERGENCY STOP" is selected.

The engine will shut down.

NOTE: When released, the switch will return to its

FG001344

original position "O" (OFF) position.

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 the 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.

8. Engine Oil Pressure Warning Light

This indicator light will turn "ON" when the engine starter

switch is turned "ON," and should go "OFF" after the

engine starts. For example, if the engine oil pressure

becomes too low, the light will turn "ON" and a warning

buzzer will sound. If this happens, shut the engine down

immediately and determine the cause of the problem. If

you continue to work when this light is "ON," it will result in

serious engine damage.

CAUTION!

If you continue to work when this light is "ON," it will

result in serious engine damage.

9. Engine Coolant Temperature Warning

Light

If engine coolant overheats, this light will turn "ON," 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 due to

heat surge.

NOTE: Check the engine coolant temperature gauge. If

HAOD350L

the gauge pointer moves into the red zone, the

Figure 57

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

the 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.

10. Engine Check Warning Light

This indicator light will turn "ON," when the engine needs to

be check.

DEVICES

Cabin Light

A light is installed on the top of the operator's compartment.

The light will work despite starter switch position.

NOTE: If light is left "ON" for a long time while the engine is

not running, the battery will be discharged.

Pilot Cutoff Switch

When the safety lever is put into the "LOCK" position, the switch

deactivates the work levers. With the work levers deactivated,

no digging/operational work can be done.

Circuit Breaker

A main circuit breaker is in the battery box. It will automatically

cut off in case of an electrical short circuit or overload. This will

prevent the electric wiring and components from being burned or

damaged.

If the circuit breaker is cut off, check all related circuits, this

means something is wrong in the electric circuit.

After maintenance, press the red button for normal operation of

circuit breaker.

If the engine does not crank, first check that the starter switch is

turned "ON" and that no power is available (No indicator lights

will light.). Check that the "A" portion (Figure 139) of the fusible

link is not broken or burned through. Replace the fusible link if

damage and investigate cause.

HAAE2120

WARNING!

Figure 139

When changing the fusible link, replace the fusible link with

the same capacity part. Otherwise, a fire could break out in

the wiring harness and/or other components of the circuit.

Always use original DOOSAN parts.

Fuse Boxes

There are two fuse boxes (Figure 140) on the left side of the

heater box. The fuses prevent electrical devices from

overloading or shorting.

A decal attached to the inside of the fuse box access cover

indicates the function and amperage of each fuse.

NOTE: For a further explanation see

“Fuse Boxes” on

page 4-77.

Spare fuses are mounted on the inside of fuse box access

cover.

Figure 140

Change a fuse if the element separates. If the element of a new

fuse separates, check the circuit and repair the circuit.

CAUTION!

Always replace fuses with the same type and capacity fuse

that was removed. Otherwise, electrical damage could

result.

machine control, then fasten the seat belt. Seat belts

must be worn across the pelvic region and adjusted

snugly to lessen the chance and severity of injury in

case of an accident. Never fasten a seat belt across the

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

machine, apply the parking brake, and then adjust the

seat.

Always, check the condition of seat belt and belt

bracket before fastening it. Do not use it with twists in

it. Replace belt or bracket if damaged or worn.
