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.
Remove the 1 lb. cylinder or close the 20 lb. cylinder valve
completely. Inspect all hoses before each use. Replace any
damaged hoses before using 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.

MAINTENANCE

CHECKING/CLEANING AIR FILTER
See Figures 14 - 15.
For proper performance and long life, keep air filter clean.
 Use the included Torx screwdriver to remove the screws
securing the engine side cover. Remove cover and set
aside.
 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.
 Replace engine side cover and reinstall screws to secure.
CHANGING ENGINE LUBRICANT
See Figure 14 and 16.
For best performance, engine lubricant should be changed
after every 100 hours or 6 months of operation.
 Use the included Torx screwdriver to remove the screws
securing the engine side 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 accompany-
ing engine manual, if applicable.
 Replace and secure the oil cap/dipstick.
 Reinstall the oil drain cover and tighten the screws.
 Replace engine side cover and reinstall screws to secure.
