SPARK PLUG MAINTENANCE

See Figure 16.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
 Remove the spark plug cap.
 Clean any dirt from around base of spark plug.
 Remove spark plug using wrench (not included).
 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.
 Measure plug 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.
SPARK ARRESTOR
See Figure 17.
NOTICE:
This product is equipped with a spark arrestor that
has been evaluated by the USDA Forest Service;
however, product users must comply with Federal,
State, and local fire prevention regulations. Check
with appropriate authorities. Contact customer
service or a qualified service center to purchase a
replacement spark arrestor.
 Inspect the spark arrestor screen for breaks or holes.
Replace if necessary.
 Use a brush (not provided) to remove carbon deposits
from the spark arrestor screen as needed.
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
performance. We highly recommend that only qualified service
technicians perform this service.
DRAINING FUEL TANK/CARBURETOR
See Figures 18 - 19.
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 OFF.
 Turn the fuel valve to the OFF position.
 Remove the fuel line from the petcock by squeezing the
ends of the retaining clip and sliding the fuel line off.
 Install one end of a drain line over the petcock, and place
the other end in a fuel container large enough to catch
the fuel being drained from the tank.
 Turn the fuel valve to the ON position.
 When the fuel has drained from the tank, close the fuel
valve and reinstall fuel line securely on petcock.
DRAINING THE CARBURETOR
 Turn the engine OFF.
 Turn the fuel valve to the OFF 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.
TRANSPORTING
 Turn the engine OFF. Disconnect any equipment that is
plugged into the generator.
 Turn the fuel valve to the OFF position.
 Allow 30 minutes of "cool down" time before transporting
the machine. Make sure engine and exhaust of unit are
cool.
 For security, insert the pins to secure the handles before
transporting.
 Grasp the handles and roll the machine to the desired
location.
 If transporting in a vehicle, drain the fuel tank, close the
fuel valve and securely restrain the generator.
 Provide a plastic sheet or absorbent pad below the
generator to catch any drips of fuel or lubricant.
