Files and how to work with them
- Sharpen using a special file holder with a saw chain round
file dia. 4.0 mm. Normal round files are not appropriate for
this work. See “Accessories” for the order number.
- The file should cut only when pushed forwards (arrow). Lift
the file 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.
- Always guide the file as in fig. shown
- The file holder makes file guidance easier. It is marked for
the correct 30° sharpening angle (keep the marks parallel
with the chain when filing, see illustration) and limits the cut
depth to the correct 4/5 of the file diameter. See “Acces
-
sories” 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 flat
file (1
). See “Accessories” for the order number.
- Round off the front of the depth limiter (

).

Cleaning the guide bar,
lubricating the sprocket nose
CAUTION: Protective gloves must be worn.
Regularly inspect the bearing surfaces of the guide bar for
damage, and clean them with a suitable tool.
If the saw is used intensively it will be necessary to lubricate the
return sprocket bearings regularly (once a week). To do this, first
thoroughly
clean the 2 mm hole at the tip of the guide bar, and
then press in a small amount of multi-purpose grease.
Multi-purpose grease and grease guns are available as acces-
sories.
