WARNING:
Before inspecting, cleaning or servicing the machine, shut
off engine, wait for all moving parts to stop, and discon-
nect 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.
WARNING:
When servicing, use only recommended or equivalent
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

OPERATION
NOTE: This tool is heavy and requires several people to
lift. To avoid back injury, keep your knees bent and lift
with your legs, not your back, and get help when needed.
HIGH ALTITUDE OPERATION
Your engine is configured for operation below 2000 feet
altitude at the factory. Your engine must be reconfigured for
operation above 2000 feet altitude. Operating the engine
with the wrong engine configuration at a given altitude may
increase its emissions, decrease fuel efficiency, degrade per-
formance, and cause irreversible damage. Engines configured
for high altitude operation cannot be operated in standard
altitude conditions. A qualified service center should ensure
that your engine is properly configured for your location.

MAINTENANCE

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 Figure 16.
For proper performance and long life, keep air filter clean.
 Loosen the screw on the bottom of the air filter cover.
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 tighten screw to secure.
NOTE: Do not run the generator without the air filter. Rapid
engine wear will result.
