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 15.
This unit uses a paper air filter. For proper performance and
long life, keep air filter clean.
Release the latches on the air filter cover. Remove cover
and set aside.
Remove the filter element.
If the filter element is dirty, blow compressed air through
the back side of the element.
Replace the element in the air filter unit.
Replace the air filter cover and fasten the latches to
secure.
NOTE: Do not run the generator without the air filter. Rapid
engine wear will result.
CHANGING ENGINE LUBRICANT
See Figure 16.
Remove the oil cap/dipstick.
Place a container underneath the oil drain plug tube to
collect used lubricant as it drains.
Loosen the oil drain plug and remove.
Allow lubricant to drain completely.
NOTE: Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
WARNING:
Do not change engine lubricant while it is hot. Accidental con-
tact with hot engine lubricant could result in serious burns.
Tighten the oil drain plug securely.
Refill with lubricant following the instructions in the
Checking/Adding Lubricant section. For amount of
lubricant needed to refill, see Product Specifications
earlier in this manual or the accompanying engine manual,
if applicable.
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 17.
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. For replacement
spark plug, see Product Specifications earlier in this
manual or the accompanying engine manual, if applicable.
Use gap spark plug tool to adjust 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.
Reinstall the spark plug cap.
CLEANING THE EXHAUST PORT AND
MUFFLER
Depending on the type of fuel used, the type and amount of
lubricant used, and/or your operating conditions, the exhaust
port and muffler may become blocked with carbon deposits.
If you notice a power loss with your gas-powered products,
you may need to remove these deposits to restore perfor-
mance. We highly recommend that only qualified service
technicians perform this service.
