Servicing the Castor Arm
Bushings
The castor arms have bushings pressed into the top and
bottom of the tube and after many hours of operation,
the bushings will wear. To check the bushings, move the
castor fork back and forth and from side to side. If the
castor spindle is loose inside the bushings, the bushings
are worn and must be replaced.
