CHECKING AND ADJUSTING PLAY OF HEAD CARRIAGE
The rotary head carriage travels on the mast,
guided by 4-6-8 guide assemblies (A).
Each guide assembly is composed of:
- Wear sliding blocks (1)
- Wear sliding block stops (3)
- Wear sliding block support (5)
- Scraper (6)
- Adjusting screw (7)
5.18
Replace the wear sliding blocks (1) when they are excessively worn or show an anomaly.
The wear sliding block stop (3) must never interfere with the guides of the mast.
The maximum play between the guide assemblies and the guides of the mast (2): 5 mm.
Too much play on the head carriage and irregular adjustments of the guide units can lead to
anomalous wearing of the rotary head and vibrations when working.
