The teeth are chamfered alternately on one side,
every third tooth remains unmachined on the side
(see Fig. 4).
Figure 4: Grinding dimensions
Hundred percent cutting performance is only as-
sured if the dimensions shown are observed.
If the machine is used correctly, resharpening of the
blades is not generally necessary.
4.3 Changing the carbon brushes
When the carbon brushes are worn, the automatic
cut-out interrupts the power supply and the ma-
chine comes to a standstill. The automatic cut-out
prevents the collector of the armature being dam-
aged by the brush springs. Constant inspection is
thus eliminated.
When replacing carbon brushes with automatic in-
feed, the connection must be laid as a loop (see Fig.
5).
Figure 5: Carbon deposits
Disconnect the saw from the
power supply. The carbon brushes
may only be replaced in pairs.
After at least every second carbon brush change,
the gaps in the armature must be cleaned out using
a plastic brush.

4.4 Adjustment of the spring bal-
ancer
The fine adjustment of the spring balancer is effect-
ed via the PLUS/MINUS screw on its housing (see
Fig. 7).
Figure 7: Spring balancer
Turn the screw in MINUS direction until the saw
is hanging freely in equilibrium (with the spring
balancer) at working height.
If the saw cannot be pulled out, the spring balancer
is jammed and a readjustment is necessary:
Turn the screw in PLUS direction until the saw
can be pulled out and start the fine adjustment
again (see above).
5. Maintenance
Malfunctions may occur during operation, but these
are generally relatively simple to remedy. Table 1:
Troubleshooting lists these malfunctions with possi-
ble causes and resulting potential remedies.
