OPERATION
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at an authorized service center.
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.
CHECKING/CLEANING AIR FILTER
See Figure 8.
For proper performance and long life, keep air filter clean.
Press the latch tabs on top of the air cleaner cover and
remove the cover.
Remove the filter element.
If the filter element is dirty, tap the filter on a hard surface
to remove dirt or debris. You can blow compressed air
through the filter from the clean side.
NOTE:
Do not use a brush to remove dirt. This will push
dirt into the fibers.
Wipe the air filter cover and body with a clean, damp
cloth.
Replace the filter and filter cover.
Press the latch tabs to secure.
NOTE
: Do not run the generator without the air filter. Rapid
engine wear will result.
MAINTENANCE
CHANGING ENGINE LUbRICANT
See Figure 9.
Remove the oil cap/dipstick.
Place a container underneath the oil drain plug to collect
used lubricant as it drains.
Unscrew 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
contact with hot engine lubricant could result in serious
burns.
Reinstall the oil drain plug and tighten 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 10.
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.
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.
engine without the proper altitude modification may increase
the engine’s emissions and decrease fuel economy and
performance.
