Service Schedule

SERVICE SCHEDULE

The following is a recommended maintenance schedule for 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 applica- tion. 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:

1An early inspection of the generator set to insure it is ready to operate when required and to identify any poten- tial 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.
