WARNING:
While operating and storing, keep at least 3 feet of clear-
ance on all sides of this product, including overhead.
Allow a minimum of 30 minutes of "cool down" time
before storage. Heat created by muffler and exhaust
gases could be hot enough to cause serious burns and/
or ignite combustible objects.
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.
OPERATION
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.

MAINTENANCE

CHECKING/CLEANING AIR FILTER
See Figure 15.
For proper performance and long life, keep air filter clean.
 Release the screws located at the top and bottom of 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.
 Replace the element in the air filter unit.
 Replace the air filter cover; reinstall screws and tighten
securely.
NOTE: Do not run the generator without the air filter. Rapid
engine wear will result.
