Changing/Adding Oil

The oil level in this generator should be checked before each use. When the oil level is low, add oil until the level is sufficient to operate this generator.
To drain the oil from this generator:
The oil should be changed after the first 20 hours of operation. The oil should then be changed every 6 months, or for every 50 hours of use time, or
when it has become contaminated with water and/or dirt.
Drain the oil while the engine is still warm to assure rapid and complete draining.
1. Place a bucket underneath the generator to catch oil as it drains.
2. Unscrew the oil drain plug located on the crankcase underneath
the oil filler/dipstick cap using 10 mm hex wrench. Figure12.
3. Allow all of the oil to drain from the generator.
4. Replace the oil drain plug and tighten using 10 mm hex wrench.
NOTE: Never dispose of used motor oil in the trash, down a drain or on the ground. Put oil in a sealed container and contact your local
recycling center or auto garage to arrange oil disposal.
To add oil to the engine crankcase:
