9.1 Shearbolt Device
With the exception of the HX-version the
plough is fitted with shearbolts (1) inside
the leg brackets (2) as standard.
After a break of the shearbolt (1), swing
back the tripped plough body with lifted
plough after loosening the pivot bolt (3)
and removing the shearbolt sections.
Fit new shearbolt and tighten it together
with the pivot bolt (3).
Use only shearbolts of the following di-
mensions and quality, as only these bolts
ensure an efficient protection against dam-
age:
