MACHINE OPERATIONS AND CONTROLS
AFTER STARTING ENGINE
Emergency stop
If there has been any abnormal actuation or trouble, turn the starting switch key to the OFF position.
If the work equipment is operated without warming the machine up 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.
BREAKING-IN THE NEW 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 running-in the machine for the initial 100 hours (as indicated by the service meter).
During running-in operations, follow the precautions described in this manual.
Idle the engine for 5 minutes after starting it up.
Avoid operation with heavy loads or at high speeds.
Avoid sudden starts, sudden acceleration, sudden steering and sudden stops except in cases of emergency.
