Normal maintenance, replacement or repair of emission con-
trol devices and systems may be performed by any qualified
repair establishment or individual with original or equivalent
parts. Warranty and recall repairs must be performed by an
authorized service center; please contact customer service
for assistance.

When servicing, use only recommended or
equivalent 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
contact customer service or a qualified 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
See Figure 18.
For proper performance and long life, keep air filter clean.
 To remove the air filter cover, pull up on the wire latch that
holds the cover in place. This will unhook the latch from
the tab on the air filter cover.
 Remove the second wire latch, at the bottom of the air
filter cover.
 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.
 Hook the wide end of the wire latch over the tab on the
air filter cover. Position the latch as shown and push the
opposite end of the latch forward until it locks the latch
into place.
 Repeat with the second wire latch.
NOTE: Do not run the generator without the air filter. Rapid
engine wear will result.
CHANGING ENGINE LUBRICANT
See Figure 19.
 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.
