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.

Resetting Maintenance Alarms

The PowerZone controller will display a warning
message when the unit is due for maintenance or
service. The maintenance or service interval is set at
250, 500 and 3,000 hours of engine running time. Once
the unit has been serviced, the appropriate maintenance
alarm reminder must be reset. Proceed as follows to
reset the maintenance alarms:
1. With the unit shut down, move the control power
switch to CONTROL ON (I). The controller will
toggle automatically to the home screen after
initialization.
2. Press ▲, ►, ▼, or ◄ to enter the maintenance
screens.
