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

- Remove the chain (K/3) and guide bar (K/4).
- Clean the interior with a brush, in particular the brake-band

NOTE: The chain brake is a very impor-
tant safety device and like any other com-
ponent subject to normal wear and tear.
Regular inspection and maintenance are
important for your own safety and must
be done by a DOLMAR service center.
