A3.3 Checking and replacing the brush motor carbon brushes on
the bench
If the brush motor carbon brushes cannot be checked and/or replaced without removing the
head from the machine (see paragraph A1.3), remove the head as described in paragraph A3.1

You are recommended to always check the brush motor carbon brushes whenever the head is
dismounted from the machine for whatever reason.
The CT 230 is available in 850 mm and 1050 mm disk head versions mounting two
different types of motor which differ in the cooling system, power (Watts) and type of
carbon brush.
