Raker (depth gauge) clearance. Too low
•
increases the potential for kickback. Not low
enough decreases cutting ability.
If cutter teeth have hit hard objects, such as
•
nails and stones, or have been abraded by
mud or sand on the wood, have the chain
sharpened by a qualified service technician.
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 qualified service technician.
Sharpen the Cutters
Be sure to file all cutters (Fig. 19a) to the
specified angles and to the same length, as fast cutting can be obtained only when all cutters
are uniform.
a. Remove the battery pack. Wear gloves for protection.
b. Properly tension the chain prior to sharpening. Refer to the section: "Adjusting the Chain
Tension" earlier in this manual.
c. Use a 1/8" (3.2 mm) diameter round file and holder (available separately). Do all of your filing
at the middle position of the guide bar.
d. Keep the file level with the top plate of the tooth. Do not let the file dip or rock.
e. Keep a correct sharpening angle of 30° between the file and the saw chain (see Fig. 19b &
19c). Always use a file holder (available separately) when sharpening saw chains by hand.
File holders have markings for the sharpening angle.
f. Using light but firm pressure, perform a stroke towards the front corner of the tooth. Lift the file
away from the steel on each return stroke.
g. M ake 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. Occasionally remove
filings from the file with a wire brush (Fig. 19d).
