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: press in the lock tab and swing the air
filter cover to the right (Fig. 11).
2. Remove the air filter from inside the air filter cover (Fig. 11).
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 inside the air filter cover (Fig. 11).
NOTE: Operating the unit without the air filter and air filter cover will
VOID the warranty.
7. Close the air filter cover: swing the air filter cover to the left and
press it closed until the lock tab snaps into place (Fig. 11).

ADJUSTING THE IDLE SPEED

If the engine will not idle properly:
1. Start the engine. Refer to Starting and Stopping.
2. Move the cruise control to the LO (slow) position and let the
engine idle.
NOTE: Make sure the choke lever is NOT engaged while 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. 12).
