Chock both sets of wheels.
Lower both rear leveling jacks, secure leveling jacks with lockpins, and extend lower tubes
by stepping on hinged pads.
Remove fire extinguish and fuel cans from power unit when generator set is in
operation. This will insure that in the event of fire extra fuel will not be involved
and extinguisher will remain accessible.
Locate fuel cans and fire extinguisher on ground away from power unit.
Do not operate generator set until power unit is properly grounded (paragraph

ungrounded power unit.
To avoid damage to equipment, make certain of voltage, frequency, and
phase requirements of load being connected to generator set.

generator set load terminal board data plate. Data plate is located on inside of generator
enclosure door near load terminals.
