30 minutes of cool down time before performing any
maintenance. Failure to follow these instructions can result
in serious personal injury or property damage.

replacement parts. Use of any other parts could create
a hazard or cause product 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 contact customer service or
a qualifed 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 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 Figures 8 - 9.
For proper performance and long life, keep air filter clean.
 Loosen the knob on the side of the engine cover. Remove
cover and set aside.

MAINTENANCE

 Loosen the screw in the center of the air filter cover.
Remove the cover and set aside.
 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. Tighten screw to secure.
 Reinstall the engine cover. Tighten knob to secure.
CHANGING ENGINE LUBRICANT
See Figure 10.
For best performance, engine lubricant should be changed
after every 100 hours or 6 months of operation.
 Loosen the knob at the side of the engine cover. Remove
cover and set aside.
 Loosen the two screws and remove the oil drain cover.
 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.
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.
 Reinstall the oil drain cover and tighten the screws.
 Reinstall the engine cover. Tighten knob to secure.
NOTE: Used lubricant should be disposed of at an approved
disposal site. See your local retailer for more information.
SPARK PLUG REPLACEMENT
See Figure 11.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
 Loosen the knob on the side of the engine cover. Remove
cover and set aside.
 Remove the spark plug cap.
