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 resharpening
. The correct filing angles are marked on the file holder.
For checking angles
●
Select sharpening tools according to chain pitch.
●
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.
●
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.
