Air Filter – Check
A dirty air filter will restrict air flow into the
carburetor, will cause poor fuel economy, and
may damage the engine. To keep the generator
in good operating condition, service the air filter
regularly. Service more frequently when
operating the generator in extremely dusty areas.
Note: Never operate the generator without the
air filter in place. Operating the generator without
the air filter in place will result in rapid engine
wear.
Remove the fan cover panel (5) by removing the
screws (6) and lifting out. Unscrew and remove
the air filter lock (1) and cover case (2). Remove
the clip (3) and air filter (4). Make sure both the
paper and foam elements of the air filter (4) are
clean and not damaged. If the foam element is
dirty, wash it. If the paper element is dirty, knock
the dirt off. If either element is damaged, replace
the air filter.
Use a nonflammable solvent or a mixture of
household detergent and warm water to wash
the foam element. Rinse the filter thoroughly to
remove all of the cleaning solution. Never let the
foam element contact engine oil.
Note: Do not wring out the filter. Wringing out the
filter may damage the filter.
Use a damp rag to wipe dirt from the case and
cover. Install the filter into the housing. Place the
clip over the filter. Place the cover case over the
filter and clip. Reinstall the lock and screw in the
cover panel.

Only qualified service personnel should perform
this maintenance procedure. Contact your local
service center to schedule this maintenance.
Engine Oil Level – Check
Always check the engine oil with the generator
on a level surface and with the engine stopped.
1. Open engine access door. Remove the
oil level gauge (1) and wipe clean.
2. Check the oil level by re-inserting the oil
level gauge.
3. If the oil level is low (2), remove the oil
filler cap (4) and add the recommended
engine oil, using the articulated funnel
supplied, until the oil level reaches the
upper mark (3) on the oil level gauge.
Use the chart below to determine which
viscosity oil to use.
4. After adding oil, install and tighten the
oil filler cap (4) and oil level gauge (1),
and close the engine access door.
Note: Non-detergent and 2-stroke engine oils will
damage the engine and must not be used.
