For checking angles
Use a STlHL filing gauge (special
accessory, see table "Sharpening
Tools"). This is a universal
tool for
checking the filing and side plate angles,
depth gauge setting, cutter length and
groove depth. It also cleans the guide
bar groove and oil inlet holes.
File correctly
N
Move the retaining latch to
ƒ
.
N
Take the battery out of the machine.
N
Select sharpening tools according
to chain pitch.
N
Clamp the bar in a vise if necessary.
N
The saw chain cannot be locked in
place on the guide bar. To
resharpen the chain by hand,
increase tension of the chain
until it
can longer be pulled along the bar.
The chain must be re-tensioned
after sharpening. The alternative is
to remove the chain from the guide
bar and resharpen it on a bench-
mounted sharpener (FG 2, HOS,
USG).
N
If you use an FG 2, HOS or USG
sharpener: Remove the chain from
the bar and sharpen according to
the instructions supplied with the
tool.
N
Sharpen the chain frequently, take
away as little metal as possible –
two or three strokes of the file are
usually enough.
N
Hold the file
horizontally
(at a right
angle to the side of the guide bar)
and file according to the angles
marked on the file holder. Rest the
file holder on the top plate and depth
gauge.
N
Always file from the inside to the
outside of the cutter.
N
The file only sharpens on the
forward stroke – lift the file off the
cutter on the backstroke.
N
Avoid touching the tie straps and
drive links with the file.
N
Rotate the file at regular intervals
while filing to avoid one-sided wear.
N
Use a piece of hardwood to remove
burrs from the cutting edge.
N
Check angles with the filing gauge.
All cutters must be the same length.
If the cutters are not the same length,
they will have different heights. This
makes the chain run roughly and can
cause it to break.
N
Find the shortest cutter and then file
all other cutters back to the same
length. It is best to have this work
done in the workshop on an electric
grinder.
Depth gauge setting
The depth gauge determines the height
at which the cutter enters the wood and
thus the thickness of the chip removed.
a
Specified distance or setting
between depth gauge and cutting
edge.
This setting may be increased by
0.2 mm (0.008") for cutting softwood in
the mild weather season – no frost.
