Removal
► Use the software or manually move the conveyor rail into a position which allows you best ac-
cess.
– To move the conveyor rail manually, pull the toothed belt of the width adjustment unit.
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation. Observe the instructions in section 1.2 "Preparatory Work..." [}15].
► Move all gantries out of the transport area as far as possible at one side of the machine.
► Loosen the movable idler pulley.
CAUTION
Loosen the movable idler pulley only as far as necessary!
► Do not remove the movable idler pulley. Otherwise the T-slot nut on the inner side will
fall into the conveyor rail.
► Carefully unthread the belt drive.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following in-
structions:
CAUTION
Installation instructions
► Check the new toothed belt before fitting it. Hold it up high. It should hang loose and
should not twist.
► Do not bend or damage the toothed belt.
► Make sure that the toothed belt is positioned accurately in the guidance on the motor
shaft or in the belt drive.
► When you tighten the idler pulley, set the tension of the toothed belt (see below).
