Files and how to work with them
- Sharpen using a special le holder with a saw chain round
le dia. 4.0 mm. Normal round les are not appropriate for
this work. See "Accessories" for the order number.
- The le should cut only when pushed forwards (arrow). Lift
the 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.
- Always guide the le as in g. shown
- The le holder makes le guidance easier. It is marked for
the correct 30° sharpening angle (keep the marks parallel
with the chain when ling, see illustration) and limits the
cut depth to the correct 4/5 of the le 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 at
le (
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, rst
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
accessories.
