IDLE SPEED ADJUSTMENT

NOTE: Careless adjustments can seriously damage your unit. An

authorized service dealer should make carburetor adjustments.

If after checking the fuel mixture and cleaning the air filter the engine

still will not idle, adjust the idle speed screw as follows:

1. Start the engine and let it run for about 2-3 minutes at a high

speed (full throttle) to warm up. Refer to the Starting and

Stopping Instructions.

NOTE: Ensure the tines are not in contact with the ground when

adjusting the idle.

2. Release the throttle control and let the engine idle. If the engine

stops, use a small Phillips screwdriver to turn the idle speed

screw clockwise, 1/8 of a turn at a time (as needed) until the

engine idles smoothly (Fig. 12).

NOTE: The tines should not rotate during engine idle.

3. If the tines rotate when the engine idles, turn the idle speed

screw counterclockwise 1/8 of a turn at a time (as needed), to

reduce idle speed.

Checking the fuel mixture, cleaning the air filter, and adjusting the

idle speed screw should solve most engine problems. If not and all

the following are true:

• The engine will not idle

• The engine hesitates or stalls on acceleration

• There is a loss of engine power

Have the carburetor adjusted by an authorized service dealer.

WARNING: The tines may turn during idle speed

adjustments. Wear protective clothing and observe all

safety instructions to prevent serious personal injury.

AIR FILTER MAINTENANCE

Cleaning the Air Filter

Failure to maintain your air filter properly can result in poor

performance or can cause permanent damage to your engine.

1. Open the air filter cover by unscrewing the cover screw (Fig. 10).

2. Remove the air filter and the screen that sits behind it (Fig. 10).

3. Wash the filter in detergent and water. Rinse the filter thoroughly

and allow it to dry.

4. Apply enough clean SAE 30 motor oil to lightly coat the filter.

5. Squeeze the filter to spread and remove excess oil.

6. Replace the air filter and the screen that sits behind it (Fig. 10).

NOTE: Operating the unit without the air filter will VOID the warranty.

7. Reinstall the air filter cover. Insert the hooks on the air filter

housing into the slots on the air filter cover (Fig. 11).

8. Swing the air filter cover to the right and align the cover screw

with the cover screw hole (Fig. 11). Tighten the cover screw to

secure the air filter cover.

NOTE: Do not over tighten as this may strip the screw.
