THE TWO BELT TENSIONING BRACKETS ARE SPRING LOADED WITH TWO TENSION SPRINGS
ON EACH. CARE SHOULD BE TAKEN TO INSURE THAT THESE SPRINGS ARE ATTACHED TO THE
TENSION ROLLER BRACKET AFTER THE BELTS HAVE BEEN REPLACED.
TO REPLACE A BELT, BRING THE BELT LACING TOT HE TOP AND PULL THE LACING PIN. REPLACE
WITH NEW BELT. ONLY FACTORY SUPPLIED BELTS SHOULD BE USED TO AVOID MOTOR FAILURE
DUE TO EXCESSIVE FRICTION. EACH BELT IS REPLACED SEPARATELY, HOWEVER, IT IS ADVISABLE
TO REPLACE BOTH BELTS AT THE SAME TIME.
IF ONE OR BOTH BELTS AT THE EXIT END OF THE MACHINE TRAVEL TO THE LEFT OR RIGHT, THE
BELT LAGGING ON THE DRIVE ROLLERS MUST BE REPLACED.
TO REPLACE THE BELT LAGGING, FIRST REMOVE THE BELT THAT IS TRAVELING OUT OF LINE.
TURN MACHINE ON AND WITH A UTILITY KNIFE, CUT ABOUT 1/8” OFF THE BELT LAGGING WITH THE
POINT OF THE KNIFE WHILE THE DRIVE ROLLER IS TURNING. BE SURE TO PLACE THE KNIFE ON THE
ROLLER SO THAT THE ROLLER IS MOVING AWAY FROM THE POINT OF THE KNIFE, LIFT UP A SECTION
OF THE CUT LAGGING AND PULL OFF UNTIL IT IS REMOVED FROM THE DRIVE ROLLER COMPLETELY.
THIS CAN BE DONE BY JOGGING THE MACHINE ON AND OFF WHILE PULLING THE CUT STRIP OF
LAGGING. ATTACH NEW BELT LAGGING. REPLACE THE BELT AND CHECK ALIGNMENT. THE BELT
WILL HAVE MOVED TO THE OPPOSITE SIDE THAT WAS CUT. THIS PROCEDURE MAY HAVE TO BE
REPEATED UNTIL THE BELTS ARE CENTERED.
