How to Sharpen the Cutters
Be careful to file all cutters (Fig. 18) 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 "ADJUSTING THE CHAIN
TENSION" section earlier in this
manual.
3. Use a 0.177" (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. 19 & 20. 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.
