OPERATION
MAINTENANCE
 Remove the air filter.
 Wash the air filter with warm, soapy water. Rinse and
squeeze to dry.
 Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the
generator. Installing the filter incorrectly will allow dirt to
enter the engine, causing rapid engine wear.
 Reinstall the air filter cover by aligniing the tabs on the
cover with the slots in the generator housing.
 Replace the engine maintenance cover and reinstall the
screw to secure.
CHANGING ENGINE LUBRICANT
See Figure 14.

Loosen the screw at the top of the engine maintenance
cover. Remove cover and set aside.
 Remove the oil fill cap/dipstick.
 Tilt the generator to the side and allow lubricant to drain
from the oil fill hole into an approved container.
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.
 Return the generator to an upright position and refill with
lubricant following the instructions in the Checking/
Adding Lubricant section previously in this manual.
For amount of lubricant needed to refill, see
Product
Specifications earlier in this manual or the accompanying
engine manual, if applicable.
 Replace and secure the oil cap/dipstick.
 Replace the engine maintenance cover and reinstall the
screw to secure.
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used lubricant.
SPARK PLUG REPLACEMENT
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 cover.
 Remove the spark plug cap.
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from
spark plug. Allow 30 minutes of cool down time before
performing any maintenance. Failure to follow these
instructions can result in serious personal injury or
property damage.
NOTICE:
Periodically inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts, caps,
etc. Tighten securely all fasteners and caps and do not
operate this product until all missing or damaged parts
are replaced. Please call 1-800-860-4050 or contact an
authorized service center for assistance.
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

For proper performance and long life, keep air filter clean.

Loosen the screw at the top of the engine maintenance
cover. Remove cover and set aside.
 Depress tabs on top and bottom of air filter cover. Remove
cover and set aside.
HIGH ALTITUDE OPERATION
Specific modifications are needed for high-altitude operation
for equipment operating in altitudes greater than 5000 feet
above sea level. Please contact your authorized service cen-
ter for important information regarding these modifications.
Operating this engine without the proper altitude modifica-
tion may increase the engine’s emissions and decrease fuel
economy and performance.
