PREVENTIVE
MAINTENANCE
Reasonable care in preventive maintenance will insure
high reliability and a long life for the engine generator set
and the Automatic Transfer Switch.
*************
***** WARNING ****
*************
When performing any type of maintenance on this
equipment make sure the selector switch on the engine
generator is in the off position. If you are working in the
Automatic Transfer Switch, confirm with a reliable meter
that all power has been disconnected.
AUTOMATIC TRANSFER SWITCH
Clean and inspect the switch once a year. De-energize all
power sources, both line and engine generator set, then
brush and vacuum away any excessive dust and dirty
accumulation. You can at this time with the contactor de-
energized remove the contactor covers and check the
contacts. Make sure the contacts are clean and not
burned or pitted.
ENGINE GENERATOR SET
Service the engine in accordance with the engine
manufacturers manual provided with your new equip-
ment. Routinely remove debris and dirt from around and
inside generator enclosure. Insure that the air intakes are
free from leaves and other debris at all times.
Clean and inspect battery terminals at least twice a year.
Check the battery water level at least twice a year also.
Other than keeping the generator clean and free of debris
there is no other routine or preventive maintenance
required, as long as the generator is run once a week to
keep it dry and in good working order.
