3.4 Changing the carbon brushes
When the carbon brushes are worn, the automatic
cut-out interrupts the power supply and the
machine comes to a standstill. The automatic cut-
out prevents the collector of the armature being
damaged 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
Figure 9: Carbon deposits
After at least every second carbon brush change,
the gaps in the armature must be cleaned out using
a plastic brush.
Figure 10: Armature
Disconnect the saw from the
power supply. The carbon brushes
may only be replaced in pairs.
