•
If you use a file holder or the FG 1:
Leave the chain on the bar.
•
Clamp the bar in a vise if necessary.
•
Lock the chain - push hand guard
forward
•
To rotate the chain - pull hand
guard against front handle
•
Sharpen chain frequently, take
away as little metal as possible -
two or three strokes of the file are
usually enough
•
Always file from the inside to the
outside of the cutter.
•
The file only sharpens on the
0°
forward stroke -
lift the file off the cutter on the back-
stroke.
•
Hold the file KRUL]RQWDOO\ for all
chain types (at right angle to side of
guide bar) and file according to the
angles marked on the filing tool.
•
Avoid touching the tie straps and
drive links with the file.
•
Rotate the file at regular intervals
while filing -
this avoids one-sided wear.
•
90°
Use a piece of hardwood to remove
burrs from cutting edge.
•
Check angles with the filing gauge.

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.
This can be very time consuming - it is
best to have it done in the workshop on
an electric grinder.
