Checking Generator Drive Plate Torque

Replace fan/ALD drive belt
* If the unit is operated in a harsh environment or fuel quality is questioned, replace every 250 hours instead of every 500 hours.

Engine Break-In Requirements

NOTE: During the first 20 hours of operation, avoid long
periods of no load or sustained maximum load operation.
If the generator is to run for longer than five minutes
without a load, shut down the generator.
Operate the engine at heavy loads (60–90% of
maximum) as much as possible. If the engine has spent
significant time at idle, constant speed(s), or light load, or
if makeup oil is required, a longer break in period may be
needed. Refer to the engine operator's manual for a full
description of necessary procedures on the addition of
break-in oil and extension of the break-in period. For
more information on regular maintenance intervals, refer
to
Basic Maintenance Schedule.
