Step 4: Review of brushes.

Back cover

Carbon brushes

Tools:

4 hexagon socket and torque wrench

Tightening:

5 Nm o 3.7 Lbf.ft

Screw cap carbon brushes DIN 7991 M -6x16
A2 INOX 2

To check t he brushes, it is necessary t o remove the
back cover and follow t he st eps.

ATTENTION: after removing the sealing caps and housings it is
very important to make sure they close tight again. If the gasket is
in a bad condition, then seal with silicone.

Check t he cable connect ions w it h t he brushes and
