How To Sharpen The Cutters
Be careful to file all cutters (Fig. 29) 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 0.177" (4.5 mm) diamet er
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° betwe en the file and the saw
chain; see Fig. 30 & 31. 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.
