Periodic maintenance
All inspections must be done with the machine switched off.
Although the intervals between these inspections depend on the frequency of use of the
brake, they should be done every 3 months in any case so as not to compromise all
aspects of safety.
1.
Check that the play between each lining pad and the friction disc does not exceed 1 mm. If
the play is too large adjust it to the initial value as described in Chapter 9.1. When the wear
of each lining reaches 5 mm replace it as described in Chapter 9.2.
2.
Check that the surfaces of the linings and the disc are not contaminated with grease, oil or
similar substances as these prevent the brake from working effectively.
3.
Check that the anchoring screws of the brake and the brake units are correctly tightened.
