9.1 Dust emission reduction system

(ref.12, fig.1).
11. MAINTENANCE
- Maintenance operations must be performed by suitably
trained, experienced personnel.

replacement parts.
- It is advisable to remove any dirt and deposits formed in the
drum during mixing by washing with plenty of water.
Every two months of operation, check:
• the belt tension.
• the condition of the poly-V drive belt and pulleys.
Check weekly that the plug contacts on the electrical cabinet
are clean, dry and rust free.
- Periodically check the condition of the sheaths of the power
cables exiting the electrical panel.
- Periodically check that the machine stops rotating when the
drum safety guard is raised by 10 mm.
11.1 LIMIT SWITCH ADJUSTMENT
Adjustment of the limit switch must be carried out with the
drum safety guard in the lowered position. Loosen the cam
retaining screws, position the cam so that the track is in
correspondence with the limit switch roller, and then fully re-
tighten the screws.
11.2 CLEANING THE OUTLET GUARD

holes in the guard with the fixing holes, fit the screws and
tighten them.
Before starting the mixer, check that the outlet guard
