MAINTAINING THE AIR FILTER
Failure to maintain the air filter can result in poor performance or
can cause permanent damage to the engine. Engine failure due to
improper air filter maintenance is not covered by the product warranty.
Cleaning the Air Filter
1. Open the air filter cover: unscrew the cover screw and swing the
air filter cover to the right (Fig. 17).
2. Remove the air filter (Fig. 18).
3. Wash the air filter in detergent and water. Rinse the air filter
thoroughly and allow it to dry.
4. Lightly coat the air filter with clean SAE 30 oil.
5. Squeeze the air filter to spread and remove excess oil.
6. Reinstall the air filter (Fig. 18).
NOTE: Make sure the metal screen is seated in the air filter housing
before reinstalling the air filter (Fig. 18).
NOTE: Operating the unit without the air filter and air filter cover will
VOID the warranty.
7. Close the air filter cover: insert the hooks on the air filter cover into
the slots on the air filter housing. Swing the air filter cover to the
left and align the cover screw with the cover screw hole (Fig. 19).
Tighten the cover screw to secure the air filter cover.
NOTE: Do not over tighten as this may strip the screw.
ADJUSTING THE IDLE SPEED
WARNING:
The tines may rotate during idle speed
adjustments. Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
If the engine will not idle properly:
1. Start the engine. Refer to Starting and Stopping.
2. Release the throttle control and let the engine idle.
NOTE: Make sure the tines are not in contact with the ground when
adjusting the idle speed.
• If the engine stops, increase the idle speed. Use a small
Phillips screwdriver to turn the idle speed screw clockwise,
1/8 of a turn at a time, until the engine idles smoothly (Fig. 20).
• If the tines rotate when the engine idles, reduce the idle speed.
Turn the idle speed screw counterclockwise, 1/8 of a turn at a
time, until the tines stop moving (Fig. 20).
