3.3.6 REPLACING THE SPARK PLUG
Use spark plug F6TC, NGK BPR4ES or Champioin RN14YC.
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. Clean the area around the spark plug and remove it from the
cylinder head.
3. Set the spark plug's gap to 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gapped spark plug into the cylinder head
and torque to 15 ft/lbs. (Figure 12).

3.3.7 SPARK ARRESTOR
1. Shut off generator and allow the engine and muffler to cool
down completely before servicing spark arrestor (located on
the back of the muffler).
2. Remove the clamp and spark arrestor screen.
3. Clean the spark arrestor screen with a small wire brush.
4. Replace the spark arrestor if it is damaged.
5. Installation of the spark arrestor screen is the reverse of the
removal.
3.4 SERVICE AIR FILTER
The engine will not run properly and may be damaged if using a
dirty air filter. Clean the air filter once a year (Figure 13). Clean or
replace more often if operating under dusty conditions.
1. Remove air filter cover.
2. Wash in soapy water. Squeeze filter dry in clean cloth (DO
NOT TWIST).
3. Clean air filter cover before re-installing it.
To order a new air filter, please contact the nearest authorized
service center at 1-888-436-3722.

3.5 VALVE CLEARANCE
• Intake — 0.10 ± 0.02mm (cold), (0.003" ± 0.001" inches)
• Exhaust — 0.15 ± 0.02mm (cold) (0.005" ± 0.001" inches)
After the first 50 hours of operation, check the valve clearance
in the engine and adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or
the proper tools are not available, please take the generator to the
nearest service center to have the valve clearance adjusted. This is
a very important step to ensure longest life for the engine.
3.6 GENERAL
The generator should be started at least once every 30 days and
be allowed to run at least 30 minutes. If this cannot be done and
the unit must be stored for more than 30 days, use the following
information as a guide to prepare it for storage.
NEVER store engine with fuel in tank indoors
or in enclosed, poorly ventilated areas where
fumes may reach an open flame, spark or
pilot light as on a furnace, water heater,
clothes dryer or other gas appliance.
3.7 LONG TERM STORAGE
It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose or tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during storage. Acidic
gas can damage the fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer, as follows:
1. Remove all gasoline from the fuel tank. Use a commercially
available, non-conductive vacuum siphon.
