Air Filter – Check
A dirty air filter will restrict air flow into the
carburetor, 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 air filter cover bolt (3) and remove
the air filter cover (2).
Make sure that the air filter
(1) is clean and not damaged. If the air filter is
dirty, wash the filter. If the air filter is damaged,
replace the air filter.
Use a nonflammable solvent or a mixture of
household detergent and warm water to wash
the filter. Rinse the filter thoroughly to remove all
of the cleaning solution. After the filter has dried,
pour some engine oil onto the filter. Then
squeeze the filter to distribute the oil throughout
the filter and remove any excess oil.
Note: Do not wring out the filter. Wringing out the
filter may damage the filter.
Install the filter into the filter housing. Place the
air filter cover over the filter and reinstall the air
filter cover bolt.
Cylinder Head - Clean
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. Remove the oil filler cap (1) and wipe
the oil level gauge (2) to clean it.
2. Check the oil level by inserting the oil
level gauge into the filler neck. Do not
screw the oil filler cap in when checking
the oil level.
3. If the oil level is low (5), add the
recommended engine oil until the oil
level reaches the upper mark (4) 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.
Note: Non-detergent and 2-stroke engine oils will
damage the engine and
must not be used.
