SHARPEN THE CUTTERS
(FIG. 15, 16, 17, 18)
1. Disconnect the power cord from the power
source. Wear gloves for protection.
2. Properly tension the chain prior to
sharpening.
"ADJUSTING THE CHAIN TENSION"
earlier in this manual.
3. Always use a file holder (available
separately) when sharpening saw chains
by hand. File holders have markings for
the sharpening angle.
4. Be careful to file all cutters (Fig. 15) to the
specified angles and to the same length,
as fast cutting can be obtained only when
all cutters are uniform
5. Use a 0.177" (4.5mm) diameter round file
and holder (available separately). Do all
filing at the middle position of the guide
bar.
6. Keep the file level with the top plate of the
tooth. Do not let the file dip or rock.
7. Maintain a correct sharpening angle of 30°
between the file and the saw chain; see
Fig. 16 & 17.
8. Using light but firm pressure, stroke
towards the front corner of the tooth. Lift
the file away from the steel on each return
stroke.
9. 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 18).
NOTICE: A dull or improperly sharpened
chain can cause excessive motor speed
during cutting, which may result in severe
motor damage.
WARNING
can cause serious injury.
