engine for several minutes. Then stop the engine.
2. Loosen the side maintenance cover screw (20) and
remove the side maintenance cover.
3. Remove the oil filler cap (19).
4. Drain dirty oil into a container
thoroughly by tilting the engine
toward the oil filler neck.

back up and place into the
generator up right position.
6. Refill with recommended oil.
Fill to the upper limit of the filler neck (Fig. T).
Note. The recommended 4 stroke engine oils are either SAE30
(single viscosity) or 10W30 (multi viscosity) 4 stroke oil.
CAUTION. Check that no foreign material, debris, dust

Air filter
It is very important to maintain an air filter in proper condition.
Damage to the generator may arise if the filter has:
• Improperly been serviced (20).
• Dirt and other foreign elements adhering to the filter due
to improper installation and engine wear.
ALWAYS keep the filter clean at all times.
1. Remove the side maintenance cover (5) (Fig. U).
2. Remove the air cleaner filter cover by firstly pushing
down on the tab on the top of the air cleaner housing
(Fig. V). Once the air cleaner filter cover tab has been
released out of the filter housing, continue to detach the
air filter cover housing by raising the air filter housing
cover up and detaching it form the bottom tab.
