DEFLECTOR ADJUSTMENT - FIGURE 46
Deflectors (item 1) must be adjusted according to
the corn’s height. Position the deflectors so they are
just above the horizontal when operating in normal
conditions. In case of a very dry corn crop, raise the
deflector tubes above the ears of the corn to avoid
contact which could result in some corn falling to the
ground. Use the lower position only for very short
harvests.

FRICTION DISKS REPLACEMENT - FIGURE 47
The friction clutch protect the machine against over-
loads and reduces the load at start-up. It includes
two friction disks which are under a calibrated pres-
sure.
They are not adjustable and require no
maintenance
. In the case of frequent jams and
overheated disks, or if they need to be replaced for
any other reasons, the clutch will first need to be
taken apart.
To replace a disk:
1. Tighten nuts (item 7) to remove pressure on the
disk plates (items 5 & 6)
2. Using a hammer and a punch, unfold the tabs
(on item 1). These tabs are holding the spring
plates in place (item 2).
3. Remove the spring plates, the hub (item 3) and
the two friction disks (item 2).
4.
Clean the friction surfaces on the hub and the
housing (items 1 and 3).
5. Assemble back in the same order and push in
the tabs to hold the spring plates in place.
6.
Loosen the nuts.
