Cutter shapes
: Micro = Semi-chisel
The specified angles A and B are obtained
automatically if the recommended files or
sharpening tools and correct settings are used.
The angles must be the same on all cutters. If
the angles are uneven: Chain will run roughly,
not in a straight line, wear quickly and finally
break. As these requirements can be met only
after sufficient and constant practice:
Use a file holder: A file holder must be
used for manual re sharpening. The
correct filing angles are marked on the
file holder.
For checking angles
Use a filing gauge. 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.
For checking angles
Select sharpening tools according to chain pitch.
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.
Clamp the bar in a vise if necessary.
Sharpen the chain frequently, take away as little metal as possible
–
two or
three strokes of the file are usually enough.
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.
Always file from the inside to the outside of the cutter.
The file only sharpens on the forward stroke
–
lift the file off the cutter on the
backstroke.
Avoid touching the tie straps and drive links with the file.
Rotate the file at regular intervals while filing to avoid one-sided wear.
Use a piece of hardwood to remove burrs from the cutting edge.
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.
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.
