 Return the generator to an upright position and refill with
lubricant following the instructions in the Checking/
Adding Lubricant section previously in this manual.
For amount of lubricant needed to refill, see Product
Specifications earlier in this manual or the accompanying
engine manual, if applicable.
 Replace and secure the oil cap/dipstick.
 Reinstall the side cover. Replace the screws and tighten
securely.
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used lubricant.
SPARK PLUG REPLACEMENT
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 cover.
 Remove the spark plug cap.
 Clean any dirt from around base of spark plug.
 Remove spark plug using spark plug wrench.
 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 0.024−0.028 in.
(0.60-0.70 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.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
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.
MAINTENANCE
EXHAUST DIFFUSER
See Figure 17.
Inspect the exhaust diffuser for breaks or holes. Replace if
necessary.
 Loosen the screws on the rear cover. Remove rear cover
and set aside.
 Loosen the screw on the exhaust diffuser cap. Then,
remove the exhaust diffuser cap and exhaust diffuser.
 Use a brush to remove carbon deposits from the exhaust
diffuser.
 Replace the exhaust diffuser, exhaust diffuser cap, and
rear panel. Ensure that all screws are tightened securely.
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
NOTICE:
Remove all lubricant from the unit before draining the fuel
tank. Failure to do so could cause damage to the unit.
 Remove the fuel cap.
 Tilt the generator and allow fuel to drain from the fuel tank
into an approved container.
 When the fuel has drained from the tank, replace the fuel
cap.
DRAINING THE CARBURETOR
 Raise the generator and securely position props
underneath for support.
 Position a suitable container under the carburetor drain
line to catch fuel.
 Put the on/off switch in the OFF ( O ) position.
 Remove the carburetor drain screw cover to access the
drain screw.
 Loosen the carburetor drain screw and allow fuel to drain
completely into container.
 Retighten drain screw securely.
 Replace the carburetor drain screw cover.
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used fuel.
TRANSPORTING
 Put the on/off switch in the OFF ( O ) position.
 Close the vent on the fuel cap by rotating the fuel cap
lever to the OFF (O) position.
