Maintenance
• Coat gasket of new filter with clean engine oil. Turn filter
clockwise until gasket contacts lightly with filter adapter. Then
tighten an additional 3/4 turn.
• Fill oil sump with recommended oil and replace the oil fill plug.
(See "Before Starting the Generator" for oil recommendations).
• Wipe up any spilled oil.
• Dispose of used oil at a proper collection center.
3.2.6 REPLACING THE SPARK PLUG
Use Champion RC14YC spark plug or equivalent. Replace the
plug once each year. This will help the engine start easier and
run better.
1. Stop the engine and pull the spark plug wire off of the spark
plug.
2. To gain access, remove the four (4) socket head screws and
take off the side panel.
3. Clean the area around the spark plug and remove it from the
cylinder head.
4. Set the spark plug's gap to .76 mm (0.030 in.). Install the
correctly gapped spark plug into the cylinder head (Figure 13).
5. Push the boot firmly on the spark plug and install side panel.

3.3 SERVICE AIR FILTER

The engine will not run properly and may be damaged if using a
dirty air filter. Clean or replace the air filter paper filter every 200
hours or once a year (Figure 14). Clean or replace more often if
operating under dusty conditions. To clean or replace paper air
filter:
• Remove air filter cover and remove paper filter (Figure 14).
• Clean paper filter by tapping it gently on a solid surface. If the
filter is too dirty, replace it with a new one. Dispose of the old
filter properly.
• Clean air filter cover. Next insert new paper filter into the base
of the air filter. Re-install air filter cover.
To order a new air filter, please contact the nearest authorized
service center at 1-888-GENERAC. The air filter part number

3.4 CLEAN SPARK ARRESTOR SCREEN

The engine exhaust muffler has a spark arrestor screen. (CARB
only) Inspect and clean the screen at least once each year (Figure
15). If unit is used regularly, inspect and clean more often.
 If using the generator on any forest-covered,
brush-covered or grass-covered unimproved
land, it must equipped with a spark arrestor.
The spark arrestor must be maintained in good
condition by the owner/operator.
Clean and inspect the spark arrestor when the engine is at ambient
temperature as follows:
• Loosen the clamp and remove the spark arrestor screen from
the muffler.
• Inspect screen and replace if torn, perforated or otherwise
damaged. DO NOT USE a defective screen. If screen is not
damaged, clean it with commercial solvent.
• Replace the spark arrestor and secure with the clamp.
