Proper cooling of the generator is vital to maintain
performance and prevent equipment failure. Blocked
cabinet openings or other airflow obstructions are
potential fire hazards and can cause failures.
Periodically inspect generator cabinet openings and the
engine oil cooler for blockages. Do not allow leaves,
grass, dirt, snow or other objects to build up around the
cabinet. Keep plants and other landscaping groomed to
allow a minimum of three (3) feet of open space around
all sides of the generator. Do not place a cover over the
generator.
The engine governor is set at the factory to maintain
generator output frequency within specifications and is
readjusted if required during installation. However,
engine wear may cause frequency to vary as the
generator accumulates hours. Periodic checking and
adjustment of generator frequency by a qualified
generator technician is recommended as outlined in the
table on page 25. If speed adjustment is necessary,
follow the listed procedure to set the correct engine
speed.
1. Start the engine by moving the control panel Mode
switch to the RUN position and let the generator run
for a minimum of five minutes with no electrical loads
connected.
2. Once the generator is warmed up, check the
generator output frequency with a suitable meter.
Normal unloaded frequency is approximately 62.5
Hz.
3. Adjust engine speed to 62.5 as required by turning
the engine governor screw, shown in Fig K. Turn
the screw clockwise to increase frequency and
counterclockwise to decrease frequency.
4. Turn the engine off by moving the control panel
Mode switch back to the OFF position.

• This adjustment should only be performed by
trained personnel. If incorrect adjustments are
made, the unit may fail to operate or operate
inefficiently.

• Covering or restricting the air passages on the
generator will cause the unit to overheat and
may create a fire hazard. Do not allow snow or
leaves to cover enclosure openings.
• Leave a three foot open area around all sides of
the unit. Do not plant trees or plants which may
grow within three feet of the unit.
• Unit should be located to prevent combustible
material from accumulating against the
generator.
• The generator MUST be installed outdoors.

• Generator exhaust air contains carbon
monoxide, a deadly odorless, colorless and
tasteless gas. Breathing carbon monoxide
causes severe nausea, fainting or death. Do not
allow exhaust air to enter a building through
windows, doors, air intakes or other means.
Avoid breathing exhaust air while operating or
servicing the generator set. The engine exhaust
from this product contains chemicals known to
the State of California to cause cancer, birth
defects, or other reproductive harm.
