Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced. For replacement
spark plug, see Product Specifications earlier in this
manual or the accompanying engine manual, if applicable.
Use gap spark plug tool to adjust gap. The correct gap is
0.028−0.031 in. (0.7-0.8 mm). To widen gap, if necessary,
carefully bend the ground (top) electrode. To lessen gap,
gently tap ground electrode on a hard surface.
Seat spark plug in position; thread in by hand to prevent
cross-threading.
Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn for
proper washer compression.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.
Reinstall the spark plug cap.
CLEANING THE EXHAUST PORT AND
MUFFLER
Depending on the type of fuel used, the type and amount of
lubricant used, and/or your operating conditions, the exhaust
port and muffler may become blocked with carbon deposits.
If you notice a power loss with your gas-powered products,
you may need to remove these deposits to restore perfor-
mance. We highly recommend that only qualified service
technicians perform this service.

DRAINING FUEL TANK/CARBURETOR
See Figures 21 - 22.
To help prevent gum deposits in the fuel system, drain the
fuel from the tank and carburetor before storing.
DRAINING THE FUEL TANK
Turn the engine stop switch OFF.
Move the choke lever/fuel valve to the OFF (O ) position.
Remove the fuel line from the hose barb by squeezing
the end of the retaining clip and sliding the fuel line off.
NOTE: Make sure you are removing the fuel line that runs
between the fuel valve and the carburetor, NOT the line
that runs between the fuel valve and the fuel tank.
Place the fuel line with fuel valve in a fuel container large
enough to catch the fuel being drained from the tank.
Move the choke lever/fuel valve to the RUN position.
When the fuel has drained from the tank, move the choke
lever/fuel valve to the OFF (O) positon and reinstall fuel
line securely on hose barb.
DRAINING THE CARBURETOR
Turn the engine stop switch OFF.
Move the choke lever/fuel valve to the OFF ( O ) position.
Position a suitable container under the carburetor drain
screw to catch fuel; loosen the screw.
Allow fuel to drain completely into container.
Retighten drain screw.
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used fuel.
REPLACING FUEL FILTER
See Figure 23.
Occasionally the fuel filter may become clogged and need
to be replaced. To purchase a replacement fuel filter, contact
customer service or a qualified service center.
NOTE: Fuel tank must be empty before replacing fuel filter.
Run unit until tank is empty, if needed, or inspect filter prior
to fill-up.
To replace:
Remove both fuel lines from the old fuel filter by squeezing
the ends of the retaining clips and sliding the fuel lines off.
Reinstall fuel lines to the new fuel filter.
Pull on lines to make sure they are secured
TRANSPORTING
Turn the engine stop switch OFF.
Disconnect any equipment that is plugged into the gen-

For security, insert the pins to secure the handles before
transporting.
Tilt the machine toward you until it balances on the
wheels, then roll the machine to the desired location.
If transporting in a vehicle, drain the fuel tank, move the
choke lever/fuel valve to the OFF (O) position, and se-
curely restrain the generator.
Provide a plastic sheet or absorbent pad below the gen-
erator to catch any drips of fuel or lubricant.
