Figure 22 - Valve Clearance Adjustment
Start all four screws before tightening or you will not be able to
get all the screws in place. Make sure the valve cover gasket
is in place.
• Re-attach the spark plug wire to the spark plug.
• Repeat the process for the other cylinder.

3.7 STORAGE

The generator should be started at least once every seven days and
be allowed to run at least 30 minutes. If this cannot be done and
you must store the unit for more than 30 days, use the following
information as a guide to prepare it for storage.
DANGER

NEVER store engine with fuel in tank indoors or in
enclosed, poorly ventilated areas where fumes may
reach an open flame, spark or pilot light as on a
furnace, water heater, clothes dryer or other gas
appliance.

3.8 LONG TERM STORAGE

It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose or tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during storage. Acidic
gas can damage the fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer, as follows:

Section 3 — Maintenance
Portable Generator System
NOTICE:
• Remove all gasoline from the fuel tank.
DANGER

Drain fuel into approved container outdoors, away
from open flame. Be sure engine is cool. Do not
smoke around gasoline.
• Start and run engine until engine stops from lack of fuel.
• While engine is still warm, drain oil from crankcase. Refill with
recommended grade.
• Remove spark plugs and pour about 1/2 ounce (15 ml) of engine
oil into the cylinders. Cover spark plug hole with rag. Press the
"Start" button and allow engine to crank for 2 seconds. Then
press the "Stop" button.

Avoid spray from spark plug holes when cranking engine.
• Install and tighten spark plugs. Do not connect spark plug
wires.
• Clean the generator outer surfaces. Check that cooling air slots
and openings on generator are open and unobstructed.
• Store the unit in a clean, dry place.

3.9 OTHER STORAGE TIPS

• Do not store gasoline from one season to another.
• Replace your gasoline can if your can starts to rust. Rust and/
or dirt in your gasoline will cause problems with the carburetor
and fuel system.
• If possible, store your unit indoors and cover it to give protection
from dust and dirt. BE SURE TO EMPTY THE FUEL TANK.
• If it is not practical to empty the fuel tank and the unit is to be
stored for some time, use a commercially available fuel stabilizer
added to the gasoline to increase the life of the gasoline.
• Cover your unit with a suitable protective cover that does not
retain moisture.
DANGER

NEVER cover your generator while engine and exhaust
area are warm.
