MAINTENANCE
OIL CHANGE
Drain the oil while the engine is still warm to ensure quick and complete draining.
Remove the oil filler cap and drain the oil.
Fill with the recommended oil (see start-up) and check the level.
Oil capacity: 0.6 L.
Wash your hands with soap and water after handling used oil.
Note: Dispose of used motor oil in an environmentally friendly manner. We recommend taking it
in a sealed container to your local service to
your recovery. Do not throw it in the trash or pour it on the ground.
AIR FILTER
A dirty air filter will limit air flow to the carburetor. To avoid problems, service the air filter
periodically. Service more often when using the engine in very dusty areas.
Never use gasoline or low flash point solvents to clean the air filter element. It could cause
a fire or explosion.
CAUTION: Never run the engine without the air filter.
This will wear out the engine.
- Remove the wing nut and air filter cover. Take out the items and separate them.
Carefully check both items for holes or tears and replace them if damaged.
- Foam element: Clean it with warm soapy water, rinse it and let it dry well. You can also clean it
with a high flash point solvent and let it dry. Immerse the element in a clean, moistened engine
during initial start-up if too much oil remains in the foam.
- Paper element: Tap it several times on a hard surface to remove excess dirt or blow compressed
air through the filter from the inside out. Never try to remove dirt with a brush, as this could
force it into the fibers.
FUEL FILTER COVER CLEAN
Gasoline is highly flammable and explosive under certain conditions. Do not smoke or
allow flames or sparks in the area.
Turn the fuel valve to the OFF position and remove the fuel strainer cup and O-ring.
Wash removed parts in solvent, dry thoroughly, and reinstall securely. Turn the fuel valve
ON and check for leaks.
SPARK PLUGS
Recommended spark plug: BPR5ES (NGK) or W16EPR-U (NIPPONDENSO).
To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
Remove the spark plug cap. Be careful if the engine has been running, as the muffler will be very hot.
Visually inspect the spark plug. Discard if insulation is cracked or peeling.
Measure the spark plug gap with a feeler gauge. It should be 0.7 to 0.8 mm (0.028 to 0.031 in).
Correct as necessary by bending the side electrode.
Install the plug washer. Screw the cap on by hand to prevent it from twisting.
When installing a new spark plug, screw in 1/2 more thread with the wrench after compressing the
washer. If it's an old one, just screw in 1/8 - 1/4 more thread.
CAUTION: The spark plug must be tightened properly. An improperly tightened plug can become very hot
and damage the engine. Never use a spark plug with an improper configuration.
CLUTCH CABLE ADJUSTMENT
Measure the free play at the tip of the lever. Free play should be 3-8 mm (0.1-0.3 inch).
If the free play is incorrect, loosen the jam nut and turn the adjusting bolt in or out as necessary.
After adjustment, tighten the locknut firmly. Then start the engine and check that the clutch lever
works correctly.
THROTTLE CABLE ADJUSTMENT
Measure the free play at the tip of the lever. Free play should be 5-10 mm (0.2-0.4 inches).
If the free play is incorrect, loosen the locknut and turn the adjusting nut in or out as necessary.
After adjustment, tighten the locknut firmly.
BELT TENSION ADJUSTMENT
Standard belt tension is 60 to 65 mm (2.4 to 2.6 inches) at the tensioner pulley with the clutch.
To adjust, loosen the four engine mounting bolts and the engine mount clamping bolt. Move the
motor forward or reverse to obtain the proper belt tension.
Note: After adjusting the tension, make sure the outside face of the drive pulley is flush with the
outside face of the driven pulley using a straight gauge.
Loosen the belt stopper fixing screws.
Adjust the slack between the belt stop and the belt with the clutch lever depressed.
