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.

MAINTENANCE

 Wipe the exterior surfaces of the generator with a damp
cloth.
CHECKING/CLEANING AIR FILTER
See Figure 15.
For proper performance and long life, keep air filter clean.
 Turn the knob on the bottom of air the filter cover to re-
lease. Remove cover and set aside.
 Remove the filter element.
 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 latch to secure.
NOTE: Do not run the generator without the air filter. Rapid
engine wear will result.
CHANGING ENGINE LUBRICANT
See Figure 16.
 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.
 Reinstall the oil cap/dipstick.
NOTE: Used lubricant should be disposed of at an approved
disposal site. See your local oil retailer for more information.
SPARK PLUG MAINTENANCE
See Figure 17.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
 Locate and remove four screws on the side of the engine
cover. Remove cover and set aside.
 Remove the spark plug cap.
 Clean any dirt from around base of spark plug.
 Remove spark plug using wrench (not included).
