Note – Each accessory shaft can be removed from the machine so accessories can be
added, removed, or changed. The upper shaft and guide fingers must be removed prior
to removing the lower shaft.
Loosen the depth control lock knob (6) and turn the depth control knob (7) to the maximum
open position.
Raise the acrylic safety cover (13). Note – A safety interlock switch will prevent the
machine from running while the acrylic safety cover is raised.
Rotate the hand wheel (5) until the set screw at the operator end of the upper shaft is
accessible (figure 2). Loose the set screw using the “T” handle Allen wrench supplied with
machine.
Grasp the upper shaft and slide it toward the non-operating side of the machine until it is
disengaged from the shaft journal (figure 2). Lift the free end up and pull the shaft from the
swivel bearing at the opposite end.
If the lower shaft is to be removed, repeat this procedure. Note – Do not attempt to
interchange the shafts. When reinstalling shafts, install bottom shaft first.
To reinstall a shaft, first slide the shaft into the swivel bearing on the non-operator side of the
machine. Slide the other end of the shaft into the operator side shaft journal. Note – Be sure
that you align the dimple on the accessory shaft with the set screw hole in the shaft
journal. Tighten the shaft journal set screw using the “T” handle Allen wrench. Note – If
the lower shaft contains a stripper, make sure the bottom point is placed between the
exit roller and the tie rod.
