CAUTION
Spacer
The fastening screw for some idler pulleys also holds the spacers in place.
► Make sure that you do not loose these.
► Unthread the deflection pulley from the conveyor toothed belt and remove it.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
CAUTION
Installation instructions
► Tighten the fixing screw with a torque of 0.58Nm. Make sure that you do not tighten the screws
too much. This could cause irreparable damage to the conveyor!
The corresponding threads are only in 1.5 to 2mm thick plates and could be damaged 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!
► Use any spacers available.
► 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.
► Remove the adhesive tape, if necessary.
► While you tighten the idler pulley, set the tension of the toothed belt correctly (see Setting the
tension of the conveyor toothed belt).
