ENCLOSURE AND SITE
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.
DANGER 
•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.
CAUTION 
•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.
GOVERNOR SPEED ADJUSTMENT
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.
CAUTION 
•This adjustment should only be performed by trained personnel. If incorrect adjustments are made, the unit may fail to operate or operate inefficiently.
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.
