SERVICE SCHEDULE
22 KW - 150 KW GASEOUS STATIONARY EMERGENCY GENERATOR
The following is a recommended maintenance schedule for Gaseous Stationary Emergency Generator sets from 22kW to 150 kW in size. The

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 potential 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:

“OFF” position.
• Remove the 15 amp control panel fuse.
• Turn off the battery charger.*
• Remove the negative battery cable.
