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.

_ WARNING:
The tines may turn during idle speed _ Cover
adjustments. Wear protective clothing and observe all
1
safety instructions to prevent serious personal injury.
NOTE: Careless adjustments can seriously damage the unit. A Sears or
other qualified 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
any of the following conditions are true, take the unit to a Sears or
other qualified service dealer:
• the engine will not idle
the engine hesitates or stalls on acceleration
there is a loss of engine power
