If the cutter teeth hit hard objects such as nails and stones or are abraded by mud or sand on the wood, have an
authorized service technician to sharpen the chain.
NOTE:
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.
Sharpening The Cutters
Be careful to file all cutters (Fig 34) 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".
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. 35 & 36. 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
ach 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. See fig 37.
Warning:
sharpened chain can cause excessive motor
speed during cutting, which may result in
severe motor damage.
Warning:
sharpening increases the potential of
kickback.
Warning:
a damaged chain can cause serious injury.

CORRECT 30° – file holders are marked with guide marks
to align file properly to produce correct top plate angle.
•
LESS ThAN 30° – for cross cutting.
•
MORE ThAN 30° –feathered edge dulls quickly.
