Sharpening of cutting tools
Caution: Wear always gloves during
sharpening!

D
Note: The cutting tools below should be sharpened only at
a qualified workshop! Manual resharpening will result in
an imbalance of the cutting tool, causing vibrations and
engine damage.
• Steel bush cutter (D/1)
• Star blade (D/2)
• 8-tooth eddy blade (D/3)
Expert sharpening can be obtained from a DOLMAR service
station.
Note: To increase the working life the steel bush cutter and
the star blade may be turned over once until their second cut-
ting sides are blunt.
Chisel type saw blade
When sharpening the chisel type saw blade (E/4) with a round
file take care to sharpen all tooth recesses evenly.
The damage of only one tooth requires equal sharpening or
refiling of all other teeth.
If teeth have broken off the chisel type saw blade, it has to be
replaced.
Uneven sharpening will result in strong vibration due to an
imbalance which will cause damage to the cutter as well as
generating vibration in the handles.
Use only a special 5.5 mm dia. round file for saw blades with
support (part no. 953 009 000) to sharpen the chisel type saw
blade. Other round files are not suitable.
When hand-sharpening a mounted saw blade, make sure the
brushcutter is properly supported.
E
File only the tooth face. The file support should rest on the
back of the tooth as illustrated above (arrow).

CAUTION: Before doing any work on the brushcutter, always switch off the motor and pull
the plug cap off the spark plug. Always wear protective gloves!
CAUTION: Start the brushcutter only after complete assembly and inspection!

After it has been sharpened and resharpened several times
the chisel type saw blade must be sharpened and balanced
at a qualified workshop.
Caution:
For to safety reasons, never try to straighten or weld a
damaged cutting tool!

Always maintain a sharpening angle of 20-25 degrees (F).
For this purpose please observe that the markings on the top
surface of the file should follow in a parallel direction to the
saw blade.
The inclination should be approximately 5 degrees (F).
Setting the teeth
A
G
Should the saw blade jam during cutting, inspect the tooth
setting.
The setting should be .040" (1 mm).
To correct the setting of the saw blade teeth use the saw blade
adjusting tool which is available as an accessory
(Part no. 953 385 010).
The existing tooth setting of the saw blade must be strictly
maintained!
Push down on the adjusting tool as shown (A).
To inspect the tooth setting, hold the adjusting tool against the
saw blade. The tooth should touch against the offset part of
the adjusting tool (B).
