Setting the foreign body protection
The foreign body protection should be set as sensitive
as possible. However, a tough crop can make a less
sensitive setting necessary.
The distance “B” from the outside roll diameter to the
back of the blade (see figure) should be 0–3 mm. The
larger the distance “B”, the more sensitive the blade
safety setting, the smaller the distance, the less sensiti-
ve the blade safety setting. The blade safety should be
set as sensitive as possible, to avoid damage to the
cutter blades if a foreign body is impacted.
Attention: Check the blade safety setting from time
to time and reset if necessary.
Check all blades daily.
Only sharpen the smooth side of the blades.
Best carried out with a KRONE sharpening device.
Setting foreign body protection, blade control, and installing and removing blades
The blade safety setting is adjusted as follows:
Apply multi-purpose key (6) and press in the direction of
the arrow so that the blade safety lever is resting on the
stop screw (3) at right and left.
Release counter nut (2) and screw out stop screw (3) if
blade safety is to be made more sensitive; screw in
stop screw if blade safety is to be made less sensitive.
If the stop screw is insufficient, the disk (4) on the
profile of the shaft stub can be turned accordingly by
one tooth.
Attention: If the blade safety device actuates without a
foreign body being present, check first whether the
blades are still sharp enough.
