11 OVERLOAD PROTECTION
11.1 Shearing protection
DANGER
There are crushing and shearing points in the area of the shearing
protection.
Never remain in the plough base release area during ploughing
work.
The plough bases release upwards when the shear bolt is over-
loaded.
Ensure that an adequate safety distance is maintained.
Only shear bolts of the following dimensions and quality may be
used, as these are the only bolts that provide effective protection
against damage.
If a shear bolt (1) breaks, proceed as fol-
lows:
Release the bolt (3).
Remove the remains of the shear bolt.
Swivel the plough base back to its work-
ing position with the raised device.
Fit the new shear bolt.
Carefully tighten the shear bolt (1) and
the bolt (3). See «Tightening torques,
