Assembly:
¶ Reciprocal succession in relation to disassembly
! When performing assembly of the brackets (console)
on the three-phase motor the brackets (console)
must be picked up onto the aligning pin Pos. 9 and
lay on the both cylindrical pins Pos. 10. The inner
hexagon screws Pos. 7 must be tightened with one
tightening torque of 80Nm.
! During the assembly of the flywheel and the inter-
mediate flange the tightening torque for the inner
hexagon screws amounts to 70+5Nm
! The assembly of the adapter is carried out with
70+5Nm.
! After the assembly of the flywheel it must be tested
for true running and face strike, in which here is only
max 0,05 mm permitted.
! Align the drive motor and clamping rail unit centrally
on the support frame.

demounting or mounting the heating elements
(Fig. 28, Pos. 1) ensure that the float switch (Fig. 28,
Pos. 6) and the temperature sensor (Fig. 28, Pos. 3)
are not damaged for it can cause faulty measurement
or failure of heater controls.
Disassembly:
1. Disconnect electrical connecting cable from the
damaged heating element (Fig. 28, Pos. 1) in the
switch cabinet.
2. Pull connecting cable through the cable screwing.
3. Remove hexagon screw (Fig. 28, Pos. 4).
4. Lift off fastening panel (Fig. 28, Pos. 7).
5. Remove inner hexagon screw (Fig. 28, Pos. 5).
6. Pull down heating elements.
Assembly:
¶ The assembly is carried out in reciprocal succession.
