WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
GENERAL MAINTENANCE
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
entering 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 Figures 10 - 11.
For proper performance and long life, keep air filter clean.
Loosen the screws on the side of the engine cover.
Remove cover and set aside.
Loosen the screw in the center of the air filter cover and
turn the cover 1/4 turn clockwise, pulling the cover down
and off the unit. Remove air filter cover and set aside.
Remove both the large and the small air filters.
Wash the air filters with warm, soapy water. Rinse and
squeeze to dry.
Reinstall the air filters.
NOTE: Make sure the filters are seated properly inside
the generator. Installing the filters incorrectly will allow
dirt to enter the engine, causing rapid engine wear.
Reinstall the air filter cover. Tighten screw to secure.
Reinstall the engine cover. Tighten screws to secure.
CHANGING ENGINE LUBRICANT
See Figure 12.
For best performance, engine lubricant should be changed
after every 100 hours or 6 months of operation.
Loosen the screw at the top of the engine cover. Remove
cover and set aside.
Remove the oil fill cap/dipstick.
MAINTENANCE
Tilt the generator to the side and allow lubricant to drain
from the oil fill hole into an approved container.
NOTE: Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
Do not change engine lubricant while it is hot. Accidental
contact with hot engine lubricant could result in serious
burns.
Return the generator to an upright position and refill with
lubricant following the instructions in the Checking/
Adding Lubricant section previously in this manual.
For amount of lubricant needed to refill, see Product
Specifications earlier in this manual or the accompanying
engine manual, if applicable.
Replace and secure the oil cap/dipstick.
Reinstall the engine cover. Replace the screw and tighten
securely.
NOTE: Used lubricant should be disposed of at an approved
disposal site. See your local retailer for more information.
SPARK PLUG REPLACEMENT
See Figure 13.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
Remove the spark plug cover.
Remove the spark plug cap.
Clean any dirt from around base of spark plug.
Remove spark plug using spark plug wrench.
Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced. For replacement
spark plug, see Product Specifications earlier in this
manual or the accompanying engine manual, if applicable.
Measure plug gap. The correct gap is 0.024−0.028 in.
(0.60-0.70 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.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
