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.
NOTICE
Before operating the machine for the first time, check that there is coolant in the radiator. If the machine has been delivered
without coolant in the radiator, run water through the system to flush the system thoroughly, then fill the radiator with coolant.
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.
