Removal
CAUTION
Toothed belt
► Make sure that the toothed belt is not folded or otherwise damaged.
► Use the software or manually move the conveyor rail into a position which allows you best
access.
– To move the conveyor rail manually, pull the toothed belt of the width adjustment unit.
– Make sure that the rear side of the conveyor rail is also accessible.
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation.
Fig.116: Movable idler pulleys
► Loosen the fixing screw of the relevant
movable idler pulley(1) to release the ten-
sion of the belt.
CAUTION!
Loosen the movable idler pulley only
as far as necessary!
Do not remove the movable idler pulley
(unless you explicitly need to remove it).
Otherwise the T slot nut on the inner side
fall into the conveyor rail.

Fig.121: Inserting the pinion gear drive
► Insert the pinion gear drive.
Fig.122: Screw
► Secure the pinion gear drive with the
screw(1) (Allen, DIN EN ISO 7380-M3x4-
A2-70 [03074775‑xx]). Tighten the screw
with a torque of 0.58Nm.
CAUTION!
Make sure that you do not tighten the
screw too much. This could cause irre-
parable damage to the conveyor!
The corresponding threads are only in 1.5
to 2mm thick plates and could be dam-
aged if you use a torque which is too high.
For this reason, avoid using screws which
are too short. Use a measuring scale to
check, if needed!

► Thread in the toothed belt(3).
Make sure that the toothed belt is posi-
tioned accurately in the guidance on the
motor shaft or in the belt drive.
► Fix the washer(2) with the screw(1)
(cross head).
► When you tighten the idler pulley, set the tension of the toothed belt.
