Figure 5
The snails (3) are fastened to the drive
shaft (4) using shearing bolts (1) and safety
splints (2). The bolts are designed in such
a way that they break (shear off) when the
snail comes in contact with foreign bodies.
This protects the machine against damag-
es. These parts should only be replaced by
original spare parts (Spare bolts and safety
splints are included in standard delivery).
Î
Remove broken bolts (1) and safety
splint (2); clean and lubricate the fas-
tening point.
Î Use new shearing bolts and new safety
splint.

Note: The replacement bolts and safety
splints can be fastened to the dashboard.
