CLEANING THE AIR FILTER

See Figures 70, 71, and 72.

Note: Always clean the air filter before making any mixture adjustments of the carburetor.

1.For access to the air filter and carburetor area, loosen the three screws holding the cylinder cover.

2.Activate chain brake.

3.Lift the front of the cylinder cover past chain brake lever.

4.Lift the back of the cylinder cover past the handle.

5.Before removing the air filter from the carburetor, blow or brush as much loose dirt and sawdust from around the carburetor and chamber as possible.

Note: Make sure to pull the choke lever out to keep the carburetor from being contaminated.

6.Remove the screw securing the air filter.

7.Position a flat screw driver between the tabs and twist.

8.Lift the air filter off the air filter base.

Choose one of the following cleaning options:

9.To lightly clean, tap the filter against a smooth, flat surface to dislodge most saw dust and dirt particles.

10.For a more thorough cleaning, clean in warm soapy water, rinse, and let dry completely.

Note: An alternate method is to clean the filter with compressed air (always wear eye protection to avoid eye injury).

11.Reinstall the air filter, making sure that the tabs on the air filter are located in channels on the air filter bottom before tightening filter retainer screw.

■Clean the pre-filter every 25 tanks of fuel or sooner, if required. Remove the cylinder cover, starter assembly and the fan housing baffle for access to the pre-filter in the engine housing.

Note: If you use an air hose for drying, blow through both sides of filter.

CAUTION:

Never run the engine without the air filter, serious damage could result.

Make sure the air filter is correctly placed in the air filter cover before reassembly.
