WARNING:
While operating and storing, keep at least 3 feet

and exhaust gases could be hot enough to cause
serious burns and/or ignite combustible objects.

MAINTENANCE

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
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 Figure 17.
For proper performance and long life, keep air filter clean.
 Remove the screws from the air filter cover. Remove cover
and set aside.
 Remove the filter element.
HIGH ALTITUDE OPERATION
Specific modifications are needed for high-altitude operation.
Please contact your authorized service center for important
information regarding these modifications. Operating this
engine without the proper altitude modification may increase
the engine's emissions and decrease fuel economy and
performance.
CALIFORNIA PROPOSITION 65
WARNING:
This product, its exhaust, and other substances
that may become airborne from its use may contain
chemicals, including lead, known to the State of
California to cause cancer, birth defects, or other
reproductive harm. Wash hands after handling.
 If the filter element is dirty, clean with warm, soapy water.
Rinse and let dry.
 Apply a light coat of engine lubricant to the element, then
squeeze it out.
 Replace the element in the air filter unit.
 Replace the air filter cover and secure using screws.
NOTE: Do not run the generator without the air filter. Rapid
engine wear will result.
CHANGING ENGINE LUBRICANT
See Figure 18.
 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.
