16.1 Maintenance of plough bodies
IMPORTANT:
Protect the working surfaces of the mould boards
and the shares against corrosion by applying a light
coating of grease or oil.
ʈ
In particularly sticky soil conditions, apply a coat of liquid oil
with a sprayer or from an aerosol can on the mould boards as
VRRQDV\RXOHDYHWKH¿HOG
ʈ
When placing in storage, applying a thicker coat of oil to the
mould boards or spraying with dry graphite will slow down
corrosion.
16.2 Tightening
torques
ʈ
Observe the tightening torques of the components. For each
component, the torques vary depending on the surface
condition and the lubrication. All values in the table below are
for information only.
Important
Torque for tapered screws for the tine and strip
screw connection on the plough bodies. In contrast
to the torques for the regular type screw threads, the
tapered screws are only permitted to be tightened to
80 Nm. 80 Nm / 59 lb-ft.
