CARE AND MAINTENANCE
NOTICE: 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. 13a) 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 5/32ʺ (4.0 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. 13b & 13c). 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. Make 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. 13d).
