Files and how to work with them
‑ Sharpen using a special le holder with a saw chain round le.
File the rst cutter half with a 4.8 mm dia. round saw‑chain
le, then switch to a 4.5 mm dia. le. 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 horizontally (10
o
to the guide bar).
‑ All cutters must be sharpened to the same angle, 30°. Dif
‑
ferent angles result in a roughly, irregularly running chain,
increase wear and tear and cause chain beakage.
‑ The 85° front rake of the cutter results from the cut depth of
the round le. If the proper le is used in the right manner,
the correct front rake will be obtained automatically.

‑ 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 (
H). See "Accessories" for the order number.
‑ Round off the front of the depth limiter (
I).
‑ 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.

Cleaning the guide bar,
lubricating the sprocket nose
CAUTION:
Protective gloves must be worn!

Regularly inspect the bearing surfaces of the guide bar for dam‑
age, 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.
