3.3.6 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) Torx screws "T27" and
take off 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
14).
5. Push the boot firmly on the spark plug and install side panel.

3.4 SERVICE AIR CLEANER
The engine will not run properly and may be damaged if using a
dirty air cleaner. Clean or replace the air cleaner paper filter once
a year (Figure 15). Clean or replace more often if operating under
dusty conditions.
To clean or replace paper air filter:
• Remove air cleaner cover; then remove foam pre-filter (service
if necessary) and remove paper filter.
• 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 cleaner cover then slip pre-cleaner over filter. Next
insert new paper filter into the base of the air cleaner. Re-install
air cleaner cover.
To order a new air filter, please contact the nearest authorized
service center at 1-888-775-6937.

3.5 CLEAN SPARK ARRESTOR SCREEN
The engine exhaust muffler has a spark arrestor screen. Inspect
and clean the screen at least once each year (Figure 16). 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:
• Remove muffler heat shield from muffler by removing the four
screws.
• Remove spark arrestor from muffler by removing the four
screws.
• 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 muffler heat shield.
