How To Sharpen The Cutters
Be careful to file all cutters (Fig. 30) to the
specified angles and to the same length,
as fast cutting can be obtained only when
all cutters are uniform.
1. Remove the battery pack. Wear
gloves for protection.
2. Properly tension the chain prior
to sharpening. Refer to the
section: "ADJUSTING THE CHAIN
TENSION" earlier in this manual.
3. Use a 4.5 mm diameter round file
and holder (available separately).
Do all of your filing at the middle
position of the guide bar.
4. Keep the file level with the top plate of
the tooth. Do not let the file dip or rock.
5. Keep a correct sharpening angle of
30° between the file and the saw
chain; see Fig. 31 & 32. Always use
a file holder (available separately)
when sharpening saw chains by
hand. File holders have markings for
the sharpening angle.
6. Using light but firm pressure, stroke
towards the front corner of the
tooth. Lift the file away from the
steel on each return stroke.
7. 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. 33).
