GENERAL MAINTENANCE
Before each use, inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts, caps, etc.
Tighten securely all fasteners and caps and do not operate
this product until all missing or damaged parts are replaced.
Please contact an authorized service center for assistance.
Keep the generator in a clean and dry environment where it
is not exposed to dust, dirt, moisture, or corrosive vapors.
Do not allow the cooling air slots in the generator to become
clogged with foreign material such as leaves, etc.
Do not use a garden hose to clean the generator. Water en-
tering the fuel system or other internal parts of the unit can
cause problems that will decrease the life of the generator.
To clean the unit:
Use a soft bristle brush and/or vacuum cleaner to loosen
and remove dirt and debris.
Clean air vents with low pressure air that does not exceed
25 psi.
Wipe the exterior surfaces of the generator with a damp
cloth.
CHECKING/CLEANING AIR FILTER
See Figure 14.
For proper performance and long life, keep air filter clean.
Loosen the knob on the bottom of the air filter cover.
Remove cover and set aside.
Remove the air filter.
Remove the deflector. Wipe with a clean cloth and replace
in the air filter unit.
If the air filter is dirty, wash it with warm, soapy water.
Rinse and squeeze to dry.
MAINTENANCE
Apply a light coat of engine lubricant to the air filter, then
squeeze it out.
Replace the air filter.
Replace the air filter cover and tighten knob to secure.
NOTE: Do not
run the generator without the air filter or
gasket. Rapid engine wear will result.
CHANGING ENGINE LUBRICANT
See Figure 15.
Remove the oil cap/dipstick.
Place a container underneath the oil drainage bolt to
collect used lubricant as it drains.
Unscrew the oil drainage bolt and remove.
Allow lubricant to drain completely.
Reinstall the oil drainage bolt and tighten securely.
Refill with lubricant following the instructions in the
Checking/Adding Lubricant
section.
Reinstall the oil cap/dipstick.
NOTE:
Used lubricant should be disposed of at an approved
disposal site. See your local oil retailer for more information.
SPARK PLUG MAINTENANCE
See Figure 16.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
Remove the spark plug cap.
Clean any dirt from around base of spark plug.
Remove spark plug using wrench (not included).
Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or chipped,
spark plug should be replaced.
NOTE:
If replacing, use the following recommended spark
plug or equivalent: NGK BP6ES.
Measure plug gap. The correct gap is 0.028−0.031 in.
(0.7-0.8 mm). To widen gap, if necessary, carefully bend
the ground (top) electrode. To lessen gap, gently tap
ground electrode on a hard surface.
Seat spark plug in position; thread in by hand to prevent
cross-threading.
Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn for
proper washer compression.
NOTE:
An improperly tightened spark plug will become
very hot and could damage the engine.
