TRAK TRL Lathe, ProtoTRAK RLX CNC Safety, Installation, Maintenance, Service & Parts List
on the pedestal. When removing the belt, loosen nut “G” and advance nut “H” until the belt has
sufficient slack to be removed from the pulleys.
When installing the belt, retract nut “H” and tighten nut “G”. Initially, tension the belt such that
there is no slippage when the lathe is started at its maximum speed.
Belt tension should be checked frequently during the first days of operation, and periodically
thereafter. Keep the pulleys and belt clean and free of any foreign material to ensure long life and
maximum traction.
Adjust the belt tensions using the “Pencil Tester” approach. For the 1630RX/1630HSRX, the
specification is 3.5 to 4.0 lbs using a ½ deflection. For the 1845RX and 2470, use 3.0-3.5 lbs.
