***** WARNING *****
*****************
When performing any type of maintenance on this
equipment make sure the selector switch on the en-
gine generator is in the off position. If you are work-
ing 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-ener-
gize all power sources, both line and engine genera-
tor set, then brush and vacuum away any excessive
dust or dirty accumulation. You can at this time with
the contactor de-energized remove the contactor
covers and check the contacts. Make sure 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
equipment. Routinely remove debris and dirt from
around the inside generator enclosure. Insure that
the air intakes are free from leaves and other debris
at all times.
Clean and inspect battery terminals a 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 preventative main-
tenance required, as long as the generator is run
biweekly to keep it dry and in good working order.
COLD WEATHER OPERATION
Extreme cold weather operation requires special
considerations. Higher CCA batteries are required
for cold weather starting, 650 CCA or larger are rec-
ommended. In addition you should consider install-
ing an oil heater kit and a battery warmer for reliable
starting during cold weather.
