OPERATION

OPERATIONS, CHECKS AFTER STARTING ENGINE

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 break-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.
Immediately after starting the engine, avoid sudden starts, sudden acceleration, unnecessary sudden stops, and
sudden changes in direction.
WARMING-UP OPERATION
NOTICE
Do not accelerate the engine sharply during the warming-up operation. Sharp acceleration can shorten the service life of the
engine parts.
Do not continue the low idle or high idle operation for more than 20 minutes. It can cause oil leakage from the turbocharger.
1. After the engine starts, run it for 5 minutes in the range between low idling and medium speed to warm it up.
2. Check that the engine water temperature gauge pointer is in
the white range (above (A)).
If the engine water temperature gauge pointer is in the white
range (above (A)), the engine is warmed up.
If the engine water temperature gauge pointer has not reached
the white range (above (A)), continue the warming-up
operation more.
After finishing the warming-up operation, check that the
machine monitor is normal.
If the machine monitor is abnormal, ask your Komatsu
distributor for inspection/repair.
REMARK
While the AISS switch is in the AUTO position and the engine water temperature is low, the low idle speed is set a
little high automatically.
3. Check that the steering operation is normal, the lamps light up and go off normally, the horn sounds, and the
exhaust gas color, sound, and vibration are normal. If any of them is abnormal, ask your Komatsu distributor for
inspection/repair.
