MAINTENANCE

AIR FILTER MAINTENANCE

The air filter must be cleaned after every 50 hours of use or
six months (frequency should be increased if the generator
is operated in a dusty environment).
1. Place the generator on a level surface and allow the
engine to cool for several minutes.
2. Release the cover clips then remove the air filter cover.
3. Remove the wing nut and air filter. Carefully remove the
foam pre-filter. Clean using compressed air. DO NOT
submerge the filter in liquids or add oil.
4. Install the air filter in the housing and secure with the
wing nut. Reinstall the air filter cover and secure with
the clips.
ENGINE OIL LEVEL CHECK
Avoid skin contact with engine oil. Wear protective
clothing and equipment. Wash all exposed skin with
soap and water.
ALWAYS use the specified engine oil. Failure to use the
specified engine oil can cause accelerated wear and/or
shorten the life of the engine.
When using the generator in dusty conditions or in
extremely hot weather, change the oil more frequently.
Ambient air temperature will affect engine oil performance.
Change the type of engine oil used based on weather
conditions.
