SCHEDULED MAINTENANCE

Following is a recommended maintenance schedule for Generac small standby and residential generator sets. The
established intervals in the schedule are the maximum recommended when the unit is used in an average service
application. They will need to be decreased (performed more frequently) if the unit is used in a severe application.
Use the unit hour meter or calendar time, whichever occurs first, from the previous maintenance interval to deter-
mine the next required maintenance interval.
Service Maintenance Interval Information:
The various service maintenance intervals are designated by interval numbers as follows:
1 An early inspection of the generator set to ensure it is ready to operate when required and to identify any poten-
tial problem areas.
Performed monthly or following each 10 hours of operation of the unit and requires approximately .5 man-
hours per unit to complete.
This inspection may be performed by the end user providing the following safety steps are taken to prevent
the engine from starting automatically without warning:
To prevent injury, perform the following steps in the order indicated before starting any maintenance:
Disable the generator set from starting and/or connecting to the load by setting the control panel
AUTO-OFF-MANUAL switch to the "OFF" position.
Remove the control panel fuse.
Turn off the battery charger.
Remove the negative battery cable.
The battery charger must be turned off BEFORE removing the battery cable to prevent an over current condi-
tion from burning out sensitive control panel components and circuits.
Following all maintenance, reverse these steps to insure the unit is returned to standby setup for normal
operation when required.
2 A break-in service inspection of the generator set to ensure it is ready to operate and carry the load when
required, and to identify any potential problem areas.
Performed ONLY ONCE following the first three months or the first 30 hours of operation after purchase of
the unit and requires approximately 2.5 man-hours per unit to complete.

to accomplish and should be performed only by an authorized Generac Service Dealer.
3 An operational inspection of the generator set to ensure it is ready to operate and carry the load when required,
and to identify any potential problem areas.
Performed semi-annually or following each 50 hours of operation of the unit and requires approximately 1.5
man-hours per unit to complete.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by an authorized Generac Service Dealer.
4 A mid-level inspection of the generator set to ensure it is ready to operate and carry the load when required,
