MAINTENANCE
Cleaning the Air Filter - Continued from Page 20
NOTICE
Never dispose of soap cleaning solution used to
clean the air filter by dumping the solution into
a sewer, on the ground, or into ground water or
waterways. Always be environmentally responsible.
Follow the guidelines of the EPA or other
governmental agencies for proper disposal of
hazardous materials. Consult local authorities or
reclamation facility.
7. Dispose of used soap cleaning solution properly.
8. Dry the air filter elements by again applying a slow
firm squeezing action.
9. Once the air filters are dry, coat the air filters with
clean engine oil (see Figure 20 below).
10. Squeeze the filters to remove any excess oil.
11. Install the filters back into the unit. If there are two
filters make sure the gray (fine) air filter goes in
first followed by the black (coarse) air filter on the
outside.
12. Install the air filter cover and secure the air filter assembly.

SPARK PLUG MAINTENANCE

The spark plug must be checked and cleaned after
every 100 hours of use or 6 months and must be
replaced after 300 hours of use or every year.
1. Stop the generator and let it cool for several
minutes if running.
2. Move the generator to a flat, level surface.
3. Remove the spark plug boot by firmly pulling the
plastic spark plug boot handle directly away from
the engine (see Figure 21).
NOTICE
Never apply any side load or move the spark plug laterally when
removing the spark plug. Applying a side load or moving the spark
plug laterally may crack and damage the spark plug boot.

4. Clean area around the spark plug.
5. Using the 13/16" spark plug socket wrench
provided, remove the spark plug from the cylinder
head.
6. Place a clean rag over the opening created by the
removal of the spark plug to make sure no dirt can
get into the combustion chamber.
Inspect the spark plug for:
• Cracked or chipped insulator
• Excessive wear
• Spark plug gap (the acceptable
limit of 0.027–0.032 in.
[0.60 – 0.80 mm]) (see Figure 22).
NOTICE
Use only recommended spark plugs when servicing.
The manufacturer is not responsible for engine
damage when using spark plugs not recommended
by the manufacturer.
7. Install the spark plug by carefully following the
steps outlined below:
a. Carefully insert the spark plug back into the
cylinder head. Hand-thread the spark plug until
it bottoms out.
b. Using the 13/16" spark plug socket wrench
provided, turn the spark plug to ensure it is fully
seated.
c. Replace the spark plug boot, making sure the
boot fully engages the spark plug's tip.
