BREAKING IN YOUR 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 break in the machine for the initial 100 hours (as indi-
cated by the hour meter.)
During breaking in:
● Idle the engine for 5 minutes after starting it up.
● Avoid operation with heavy loads or at high speeds.
● Sudden starting or acceleration, unnecessarily abrupt braking
and sharp turning should be avoided except in cases of emer-
gency.
Additionally for the first 20 hours
● Avoid operating engine for prolonged periods at constant
speed (including idle.)
● Avoid high speed travelling for periods of more than 5 min-
utes.
Pay particular attention to oil pressure and temperature indicators
& check coolant and oil levels frequently during breaking in.
The precautions given in this manual for operating, maintenance,
and safety procedures are only those that apply when this product
