ELDAN MPR200T - 6.7 Adjustment of the distance between static and flying knives

Insert new knife
ad 4 The knife should now be set in place and the fixing bolts complete with
washers inserted. It is recommended that the bolts are greased.
The fixing bolts should be tightened progressively with a final tight-
ening to 320 Nm.
This process should be repeated for every knife.
6.7 Adjustment of the distance between static and flying knives
Use gloves for hand protection by maintenance work etc. The ma-
chine can be very hot after continuous operation.
When replacing the knives the use of safety glasses is necessary,
because of the danger of splinters when the knives are exposed to
strokes and bumps.
The knife clearance is set by adj usting the gap between the flying and
static knives.
Since the flying knives, Figure 8 - Pos. 3 and Figure 9 – Pos. 1, are all the
same size and their fixing is not adjus table, all the adjustment is done by
moving the static knife Figure 6- Pos. 3.
To set the clearance, turn the rotor by hand until one of the flying knives is
in line with the static knife that you wish to set.
The bolts, Figure 6 - Pos. 3, are loosened and the knife holder is
pushed forward w ith the adjustment bolt, Figure 6 - Pos. 7, until the
gap betw
een the static and the flying knives is 0,5-0,8 mm.
Tighten the bolts for the knife holder slightly. When all static knives are ad-
justed, turn the rotor by hand in order to ensure that all knives in the row
are having the right clearance.
The knife fixing bolts can now be tightened using a 14-mm Allen key
socket to a torque of 320 Nm.
Having got the setting correct and havi ng tightened the knife bolts with the
correct torque, the counter nuts on the adjustment bolts are tightened.
This operation should be repeated for all of the static knives.
