SERVICE SCHEDULE

30 KW - 150 KW STANDBY GAS ENGINE DRIVEN GENERATOR SETS

The following is a recommended maintenance schedule for standby gas engine driven generator sets from 30kW to 
150 kW in size. 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 calendar time, from the previous maintenance interval to determine 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 insure it is ready to operate when required and to identify any poten-

tial problem areas.

 

 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 15 amp 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 condition 
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 wear-in service inspection of the generator set to insure 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.

 

 This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge 
to accomplish and should be performed only by an Authorized Service Dealer.

3

   An operational inspection of the generator set to insure 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.

 

 This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge 
to accomplish and should be performed only by an Authorized Service Dealer.

4

   A mid-level inspection of the generator set to insure it is ready to operate and carry the load when required, 

and to identify any potential problem areas.

   

Performed annually or following each 100 hours of operation of the unit.

 

 This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge 
to accomplish and should be performed only by an Authorized Service Dealer.

5

   A comprehensive inspection of the generator set to insure it is properly serviced and ready to operate and carry 

the load when required, and to identify any potential problem areas.

 

 Performed annually or following each 250 hours of operation of the unit.

 

 This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge 
to accomplish and should be performed only by an Authorized Service Dealer.
