MAINTENANCE
■Raker (depth gauge) clearance.
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.

SHARPENING THE CUTTERS
See Figures 57, 58, 59, 60, and 61.
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 3/16 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 60.
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.
