How to Sharpen the Cutters

See Figures 24 - 27.

Be careful to file all cutters to the specified angles and to the same length, as fast cutting can be obtained only when all cutters are uniform.

nTighten the chain tension enough that the chain does not wobble. Do all of your filing at the mid-point of the bar. Wear gloves for protection.

nUse a 5/32 in. diameter round file and holder.

nKeep the file level with the top plate of the tooth. Do not let the file dip or rock.

nPut a few firm strokes on every tooth. File all left hand cutters in one direction. Then move to the other side and file the right hand cutters in the opposite direction. Oc- casionally remove filings from the file with a wire brush.

nUsing light but firm pressure, stroke towards the front corner of the tooth. Lift file away from the steel on each return stroke.

WARNING:

Improper chain sharpening increases the potential of kickback. Failure to replace or repair damaged chain can cause serious injury.

CLEANING THE EXHAUST PORT AND MUFFLER

Depending on the type of fuel used, the type and amount of lubricant used, and/or your operating conditions, the exhaust port and muffler may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, a qualified service technician will need to remove these deposits to restore performance.

SPARK ARRESTOR

The spark arrestor must be replaced every 50 hours or yearly to ensure proper performance of the product. Spark arres- tors may be in different locations depending on the model purchased. Please contact the nearest service dealer for the location of the spark arrestor for your model.
