SHARPENING THE CUTTERS
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.
1. Wear gloves for protection.
2. Tension the chain prior to sharpening.
Note: Refer to “Maintenance – Adjusting the Chain
Tension” earlier in this manual.
3. Use a 5/32 in. diameter round file and holder. Do all of
your filing at the midpoint of the bar.
4. Keep the file level with the top plate of the tooth. Do not
let the file dip or rock. See Figure 58.
5. Using light but firm pressure. Stroke towards the front
corner of the tooth.
6. Lift the file away from the steel on each return stroke.
7. 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.
8. Remove filings from the file with a wire brush.

CLEARANCE

■ Raker (depth gauge) clearance. See Figure 55.
1. Too low increases the potential for kickback.
2. Not low enough decreases cutting ability.
■ If the cutter teeth hit hard objects such as nails and
stones, or are abraded by mud or sand on the wood,
have the Homelite Service Center sharpen the chain.
Note: Inspect the drive sprocket for wear or damage
when replacing the chain. If signs of wear or damage
are present in the areas indicated, have the drive
sprocket replaced by a Homelite Service Center.
