PRECAUTIONS FOR OPERATION
•
Before starting the engine, check that lock lever (1) is in
LOCK position (L).
•
Adjust the mirrors to have a good rear view and a good
view of surrounding area from the operator's seat.
For the adjustment, see "METHOD FOR ADJUSTING
MIRRORS"
•
Adjust the cameras to have a good rear view and a good
view of surrounding area from the operator's seat.
For the adjustment, please contact your Komatsu distribu-
tor.
•
Adjust the armrest to a position for easier operation, and
fix it securely. Operation in an improper position can cause a serious personal injury or death.
•
Check that there are no persons or obstacles above, below, or in the area around the machine.
PRECAUTIONS WHEN STARTING ENGINE
The machine may suddenly move off and this may lead to serious personal injury or death. Always observe the
following.
•
Start the engine only while sitting down in the operator's seat.
•
When starting the engine, sound the horn as a warning.
•
Prohibit other personnel to get on the machine.
•
Do not attempt to start the engine by short-circuiting the engine starting circuit. This may cause fire, serious
personal injury or death.
IN COLD WEATHER
•
If the warm-up operation is not performed thoroughly, and the work equipment is operated, the reaction of
the work equipment to the operation of the control levers and pedals will be slow and the movement of it
may not be what the operator intended. Be sure to perform the warm-up operation. Particularly in a cold
weather, be sure the warming-up operation is completed.
•
If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power
source. There is a hazard that this will ignite the battery and cause the battery to explode.
Before charging or starting the engine with a different power source, melt the battery electrolyte and check
that there is no leakage of electrolyte before starting.
START ENGINE WITH JUMPER CABLES
If any mistake is made in the method of connecting the jumper cables, it may cause the battery to explode, so
always observe the following.
•
Always wear protective eyeglasses and rubber gloves
when starting the engine by using the jumper cables.
•
When connecting a normal machine to a failed machine
with the jumper cables, always use the normal machine
with the same battery voltage as the failed machine.
•
When starting the engine with the jumper cables, perform
the starting operation with 2 workers (one worker sitting in
the operator's seat and the other working with the battery).
•
When starting from another machine, be careful that the
normal machine does not contact with the failed machine.
•
When connecting the jumper cables, turn the starting
switch to OFF position for both the failed machine and the normal machine. If the failed machine has a bat-
tery disconnect switch, turn it to OFF position, and turn it ON again after connecting the cables.
It is dangerous that the machine may move when the power is connected.
•
Be sure to connect the positive (+) cable first when installing the jumper cables. Disconnect the negative (-)
cable (ground side) first when removing them.
