Use only special saw chain sharpening
files. Other files have the wrong shape
and cut.
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
Disconnect the plug from the wall
N
outlet.
Select sharpening tools according
N
to chain pitch.
Clamp the bar in a vise if necessary.
N
To rotate the chain – pull hand
N
guard against handle to disengage
the chain brake Hold the hand guard
in this position – the coasting brake
is disengaged.
Sharpen the chain frequently, take
N
away as little metal as possible –
two or three strokes of the file are
usually enough.
MSE 250 C
Hold the file horizontally (at a right
N
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.
Always file from the inside to the
N
outside of the cutter.
The file only sharpens on the
N
forward stroke – lift the file off the
cutter on the backstroke.
Avoid touching the tie straps and
N
drive links with the file.
Rotate the file at regular intervals
N
while filing to avoid one-sided wear.
Use a piece of hardwood to remove
N
burrs from the cutting edge.
Check angles with the filing gauge.
N
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.
Find the shortest cutter and then file
N
all other cutters back to the same
90°
length. It is best to have this work
done by a servicing dealer 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.
