damage and increase risk of injury.

AC Belt Replacement
The following instructions outline the AC motor replacement procedure.
1.
Ensure that the power to the AC motor is switched off.
ZiPline Conveyor recommends using
Lockout/Tagout (LOTO) procedures for this operation.
2.
Manually move the belt to where the belt splice is easily accessible.
3.
Mark/measure the position of the tensioner rods on the drive section of the conveyor.
4.
Loosen the take-up equally on both sides of the conveyor. This relaxes the belt tension across
the conveyor. To loosen the take-up pulley, move the take-up bearings towards the upstream
side of the conveyor.
5.
Remove the belt splice pin from the splice.
Prior to removing the belt splice pin, ensure that you have access to a new splice pin.
The belt splice pin is a consumable part and will require replacement if the splice is
removed.
6.
Remove the belt from the conveyor.
7.
Install the new belt and route the belt through the conveyor. Splice the ends of the belt. Refer to
section 5.3 for detailed information on belt installation.
8.
Re-track and re-tension the belt. Refer to section 5.4 for further information.
