OPERATION

OPERATIONS AND CHECKS AFTER STARTING ENGINE

q Emergency stop
If the operation is abnormal or any other trouble occurs, turn the key in the starting switch to the OFF
position.
q 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.
NOTICE
When the hydraulic oil temperature is low, do not carry out operations under heavy load or at high speed.
There is danger that the pump may be broken.

BREAKING-IN THE MACHINE

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 performance and shorten the
machine life.
Be sure to break-in the machine for the initial 100 hours (as indicated by the service meter).
During breaking-in operations, follow the precautions described in this manual.
q Idle the engine for 5 minutes after starting it up.
q Avoid operation with heavy loads or at high speeds.
q Immediately after starting the engine, avoid sudden starts, sudden acceleration, unnecessary sudden stops,
and sudden changes in direction.
