2. AIR CLEANER SERVICE
A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor
malfunction, service the air cleaner regularly. Service more frequently when
operating the generator in extremely dirty areas.
n Do not use gasoline or low flash point solvents for cleaning. They are flammable
and explosive under certain conditions.
n Never run the generator without the air cleaner, otherwise rapid engine wear may
result.
a. Open service door.
b. Unsnap the clips and remove the air cleaner cover.
c. If the paper element is dirty, torn, or replacement is called for based on hours of
operation, replace it with a new one. Do not attempt to clean the element.
d. Reinstall the air cleaner cover.
e. Close and latch the service door.
n Please dispose of used motor oil in a manner that is compliant with environment
and local disposal regulations. Do not throw it in the trash, pour it on the ground,
or down the drain.
3. SPARK PLUG MAINTENANCE

of deposits.
Recommended spark plug: WR7DC
To ensure proper engine operation, the spark plug must be properly gapped and free
of deposits.
a. Open the service door.
b. Remove the spark plug cap.
c. Use the wrench provided to remove the spark plug.
d. Clean any dirt from around the spark plug base.
e. Visually inspect the spark plug. Discard if the insulator is cracked or chipped.
Clean the spark plug with a wire brush if it is to be reused.
f. Measure the plug gap with a feeler gauge. The gap should be 0.028-0.031in (0.7-
0.8mm). Correct as necessary by carefully bending the side electrode.
g. Install the spark plug carefully, by hand, to avoid cross-threading.
h. After a new spark plug has been seated by hand, it should be tightened 1/2 turn
with a wrench to compress the sealing washer. If a used plug is being reinstalled,
it should only require 1/8 to 1/4 turn after being seated.
