SERVICE

GH
- 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.

CAUTION: Before doing any work on the guide bar or
chain, always switch off the engine and pull
the plug cap off the spark plug (see "Replacing
the spark plug"). Always wear protective gloves!
CAUTION: Start the chain saw only after having assem-
bled it completely and inspected.

STOP

- Remove the sprocket guard (K/1) (See "PUTTING INTO
OPERATION" figs. A and B).
- Turn the chain tightener screw (K/2) to the left (counter-
clockwise) until you feel resistance.
- Remove the chain (K/3) and guide bar (K/4).
- Clean the interior with a brush, in particular the brake-band
area (K/5).
NOTE: Make sure that no residue or contaminants remain in
the oil guide groove (K/6) and the chain tightener (K/7).
- For replacing the guide bar, chain, and sprocket see
"PUTTING INTO OPERATION".
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.
