SERVICE SCHEDULE
The following is a recommended maintenance schedule for Stationary Emergency 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 calendar time or accumulated run 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.
Performed monthly this 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 5 amp and 15 amp control panel fuses.
• Turn off the battery charger (turn OFF utility supply to ATS).
• 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 break-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.

mately 2.5 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 a Service Dealer.

problem areas.
