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 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.
INFLATING THE TIRES
WARNING:
To reduce the risk of injury, do not over-inflate the tires
of this unit. During inflation regularly check the pressure
using a reliable tire pressure gauge, and never exceed
25 psi. Always ensure the bolts in the wheel hubs are
securely tight before adding pressure to the tire.
NOTE: THE TIRES SHOULD BE INFLATED US-
ING A HAND PUMP ONLY. DO NOT USE AN AIR
COMPRESSOR.
CHECKING/CLEANING AIR FILTER
See Figure 13.
For proper performance and long life, keep air filter clean.
 Loosen the screws on the top and bottom of the air filter
cover. Remove cover and set aside.
 Remove the filter element.
 If the filter element is dirty, clean with warm, soapy wa-
ter. Rinse and let dry.
 Apply a light coat of engine lubricant to the element,
then squeeze it out.

MAINTENANCE

 Replace the element in the air filter unit.
 Replace the air filter cover and tighten screws to secure.
NOTE: Do not run the generator without the air filter. Rapid
engine wear will result.
CHANGING ENGINE LUBRICANT
See Figure 14.
 Remove the oil cap/dipstick.
 Place a container underneath the
used lubricant as it drains.
 Unscrew the
 Allow lubricant to drain completely.
 Reinstall the
 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 ap-
proved disposal site. See your local oil retailer for more in-
formation.
SPARK PLUG MAINTENANCE
See Figure 15.
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 BPR4ES.
 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.
