3.3.3 Operations and checks after starting engine
WARNING
z Emergency stop
If the operation is abnormal or any other trouble occurs, turn
the key in the starting switch to the OFF position.
z If the work equipment is operated without warming up the
machine sufficiently, the response of the work equipment to
the movement of the control lever will be slow, and the work
equipment may not move as the operator desires, so always
carry out the warming-up operation. Particularly in cold
areas, be sure to carry out the warming-up operation fully.
NOTE
When the hydraulic oil temperature is low, do not carry out oper-
ations under heavy load or at high speed. There is danger that
the pump may be broken.
Breaking-in the machine
CAUTION
Your KOMATSU machine has been thoroughly adjusted and
tested before shipment. However, operating the machine under
severe conditions at the beginning can adversely affect the per-
formance and shorten the machine life.
Be sure to break-in the machine for the initial 100 hours (as indi-
cated by the service meter).
During breaking-in operations, follow the precautions described
in this manual.
z
Idle the engine for 5 minutes after starting it up.
z
Avoid operation with heavy loads or at high speeds.
z
Immediately after starting the engine, avoid sudden starts,
sudden acceleration, unnecessary sudden stops, and sud-
den changes in direction.
