Cleaning the Generator
CAUTION
DO NOT spray generator directly with water.
Water can enter the generator through the cooling slots and
damage the generator windings. It can also contaminate the
fuel system.
1. Use a damp cloth to clean exterior surfaces of the generator.
2. Use a soft bristle brush to remove dirt and oil.
3. Use an air compressor (25 PSI) to clear dirt and debris from
the generator.
4. Inspect all air vents and cooling slots to ensure that they are
clean and unobstructed.
To prevent accidental starting, remove and ground the spark plug
wire before performing any service.
Changing the Engine Oil
Change oil when the engine is warm. Refer to the oil specification
to select the proper grade for your operating environment.
1. While holding the flat part of the drain tube with pliers or
wrench, remove the oil drain bolt with a 10 mm socket or
wrench.
