Sharpening the cutterS
•
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.
•
Tension the chain prior to sharpening. Refer to Adjusting The Chain Tension.
•
Use a 5/32 in. (4 mm) diameter round file and holder. Do all of your filing at the midpoint
of the bar.
•
Keep the file level with a top plate of the tooth. Do not let the file dip or rock.
•
Using light but firm pressure. Stroke towards the front corner of the tooth.
•
Lift the file away from the steel on each return stroke.
•
Put 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.
•
Remove filings from the file with a wire brush.

Make sure the battery is removed from the chainsaw before you work on the saw.

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

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