1. STARTING ENGINE & STOPPING ENGINE
1.1 STARTING ENGINE
• Start the engine only when the operator is sitting on the operator's seat.
• Do not start the engine by short-circuiting the starter circuit. Doing so may cause
serious physical injury or fire.
• Before starting the engine, make sure no personnel or impediments are close to the
machine and honk the horn.
• Exhaust gas is toxic. When starting the engine in a narrow, enclosed place, pay due
attention to ventilation.
CAUTION
• If it is difficult to start the engine because the
temperature is low, perform the cold climate engine
starting operation.
• Do not start the engine by turning the fuel adjustment
dial to near the full rotation position (MAX). Engine
parts may be damaged.
• Do not keep the starter turned for more than 20
seconds. Doing so will accelerate the battery
discharge.
If the engine fails to start, wait for 2 minute before
retrying.
1. Confirm that the disconnect switch in the battery box is
turned to ON position.
If it is turned OFF, engine does not start.
2. Check that the lock lever (1) is in the lock position (L).The
engine does not start if the lock lever (1) is in the free
position (F).
NORMAL ENGINE START
1. Turn the fuel adjustment dial (2) to the low idling position
(MIN).

- 3 -
2. Insert the key into the starter switch (3) and turn the key to
the "START" position. The engine starts.
3. When the engine has started, release your hand from the
key.
The key automatically returns to the "ON" position.
4. Continue the idling operation for 15 seconds immediately
after engine start. Do not operate the operation levers and
fuel adjustment dial during this period.
ENGINE START IN COLD CLIMATE
1. Check, before starting the engine that the fuel adjustment
dial (2) is in the low idling position (MIN).
2. Turn the fuel adjustment dial (2) to position between the
low idling position (MIN) and full rotation position (MAX).
3. Insert the key into the starter switch (3), turn the key to
the "ON" position and check that the auto glow lamp turns
on.
When preheating is completed, the auto glow lamp goes
on.
4. When the auto glow lamp goes out, turn the starter switch
key to the "START" position. The engine starts.
5. When the engine has started, release your hand from the
key.
The key automatically returns to the "ON" position.
6. Continue the idling operation for 15 seconds immediately
after engine start. Do not operate the operation levers
and fuel adjustment dial during this period.

1.2 STOPPING ENGINE
CAUTION
• Stopping the engine before it sufficiently cools down
may shorten the life of engine units. Do not stop the
engine suddenly except for an emergency.
• When the engine is overheated, do not stop the
engine suddenly. Change the engine speed to low,
and gradually cool down the engine before stopping.
1. Turn the fuel adjustment dial (2) to the low idling position
(MIN) and continue operation under no load for
approximately 5 minutes.
2. Turn the starter switch key (1) to the “OFF” position.
The engine stops.
3. Remove the starter switch key (1).

2. OPERATION LEVERS
(1) Lock lever
(2) Travel lever (with auto deceleration mechanism)
(3) Left work equipment operation lever
(with auto deceleration mechanism)
(4) Right work equipment operation lever
(with auto deceleration mechanism)
(5) Accelerator pedal
[1] LOCK LEVER
•When standing up from the driver seat, place the lock lever securely in the lock position (L). If the
lock lever is in the free position (F) and contacts the operation levers and operation pedals
carelessly, serious physical injury may be caused.
•When you leave the driver seat or work is suspended, check that the lock lever is securely in the lock
position (L).
•When pulling up or pushing down the lock lever, be careful not to allow it to contact the operation
lever of work equipment.
Use this lever to lock crane operation, slewing and travel operation.
•(L) Lock: Pull up the lever. The machine does not move even if each
operation lever is operated.
•(F) Free: Push down the lever. The machine moves if each operation
lever is operated. NOTES
Because the machine is hydraulically locked by the lock lever,
operation levers move even if the lever is placed in the lock position.
However, the machine does not move.

- 6 -
[2] TRAVEL LEVER
•When the sprocket (A) side is in the rear, the track frame faces
forward. When the track frame faces rearward, the direction
of travel lever operation is opposite to the direction of
machine movement (forward and rearward movement, right
and left movement direction).
When operating the travel lever, be sure to check if the track
frame faces forward or rearward.
Use this lever to move the machine forward/rearward, stop, change
the direction, and adjust the travelling speed.
•(a) Forward movement: Push the lever forward.
•(b) Rearward movement: Pull the lever toward you.
•(N) Neutral: Release your hand from the lever.
NOTES
When the travel lever is operated to the forward or rearward direction
from neutral, the alarm sounds and notifies the surrounding area that
the machine will start moving.
[3] LEFT WORK EQUIPMENT OPERATION LEVER
Use this lever to perform slewing operation of the revolving super
structure and extension and retraction operation of the boom.
Slewing operation
•(a) Right slewing: Pull the lever in the right direction.
•(b) Left slewing: Push the lever in the left direction.
Extension and retraction operation of boom
•(c) Retraction of boom: Pull the lever rearward.
•(d) Extension of boom: Push the lever forward.
(N) Neutral: Release your hand from the lever.
The revolving upper structure and boom length retain their positions as they stop.
[4] RIGHT WORK EQUIPMENT OPERATION LEVER
Use this lever to perform winch operation and boom derricking
operation.
Winch operation
•(e) Hoisting: Pull the lever rearward.
•(f) Lowering: Push the lever forward.
Boom derricking operation
•(g) Lowering of boom: Push the lever in the right direction.
•(h) Raising of boom: Pull the lever in the left direction.
(N) Neutral: Release your hand from the lever.
The hook block and boom angle retain their positions as they stop.

[5] ACCELERATOR PEDAL
Use the accelerator pedal only when the machine stops and you operate the crane.
Never use this pedal during travel operation. An operation mistake may be made, resulting in serious
physical injury.
Use the fuel adjustment dial to adjust engine speed during travel operation.
Use this lever to adjust the engine speed or output during crane
operation.
•(a) Low idling: Release your foot from the pedal.
•(b) Full revolution: Depress the pedal fully.
NOTES
As a priority is given to the engine speed of the fuel adjustment dial,
the engine speed does not fall below the set speed of the fuel
adjustment dial even if you release your fool from the accelerator
pedal.
When performing work using the accelerator pedal, operate the fuel
adjustment dial in advance to set the necessary minimum engine
speed.
