CAUTION
Do not underfill or overfill the oil bath cups. Overfilling of cups causes loss of capacity; underfilling cups causes lack of filtering efficiency.

The lower portion of the air cleaner should be inspected each time the oil cup is inspected or serviced. If there is any sign of contaminant buildup or plugging, the body assembly should be removed and back flushed.
At least once a year or at regular engine service periods, remove the entire air cleaner and perform the following:
1. Remove oil cups. Check and clean center tube.
WARNING
Do not use gasoline to clean air cleaner parts.
2.Pump solvent through the air outlet with sufficient force and volume to produce a hard, even stream out of the bottom of the body assembly. Reverse flush until all foreign material is removed.

4.5.1Preventative Maintenance and Operating Precautions
Costly repairs and down time can usually be prevented by operating electrical equipment under conditions that are compatible with those under which the equipment was designed. Follow the instructions outlined below to insure maximum efficiency of the electrical equipment.
a. Cooling
Keep all cooling parts clean. DO NOT EXCEED TEMPERATURE RISE OF 80C (176F) ABOVE A 40C
(104F) AMBIENT. This ensures that the NEMA Class âFâ insulation will not be damaged. DO NOT EXCEED RATED LOAD except as specified for the equipment. OPERATE GENERATOR AT RATED SPEED. Failure to operate generators at rated load or speed will cause overheating and possible damage to windings due to over voltage or current.
