MAINTENANCE

SHARPENING THE CUTTERS

See Figures 49 - 52.

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

WARNING:

The saw chain is very sharp. Always wear pro- tective gloves when performing maintenance to the chain to prevent serious personal injury.

nTension the chain prior to sharpening. Refer to Adjusting The Chain Tension.

nUse a 3/16 in. diameter round file and holder. Do all of your filing at the midpoint of the bar.

nKeep the file level with the top plate of the tooth.

Do not let the file dip or rock.

nUsing light but firm pressure. Stroke towards the front corner of the tooth.

nLift the file away from the steel on each return stroke.

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.

nRemove filings from the file with a wire brush.

CAUTION:

A dull or improperly sharpened chain can cause excessive engine speed during cutting, which may result in severe engine damage.

WARNING:

Improper chain sharpening increases the poten- tial of kickback.

WARNING:

Failure to replace or repair a damaged chain can cause serious injury.
