Files and how to work with them
Sharpen using a special fi le holder with a saw chain round
fi le. Normal round fi les are not appropriate for this work. See
„Accessories" for the order number.
File the fi rst cutter half with a 5.5 mm dia. round saw-chain
fi le, then switch to a 4.8 mm dia. fi le.
The fi le should cut only when pushed forwards (arrow). Lift the
fi le when leading it backwards.
First sharpen the shortest cutter. The length of this cutter is then
the standerd for all other cutters of the chain.
New saw teeth must be fi led to the exact same shape as the
used teeth, including on their running surfaces.
Always guide the fi le horizontally (10
The fi le holder makes fi le guidance easier. It is marked for the
correct sharpening angle of 25° (keep the marks parallel with
the chain when fi ling, see illustration) and limits the cut depth
to the correct 4/5 of the fi le diameter. See „Accessories" for the
order number.
After having sharpened the chain, the height of the depth limiter
must be checked by means of a chain gauge. See „Accessories"
for the order number.
Correct even the smallest excess height with a special fl at
fi le (1). See „Accessories" for the order number.
