OPERATION
NOTE:
With the DC Motor Assembly off of the lathe, the
sliding bed can be moved manually. The Sliding Bed Handle
(#C9), FIG. 27, can now be used to pull/extend the sliding
bed away from the headstock. Just push the end of the
sliding bed to move it back towards the headstock. Make
sure that the sliding bed’s locking handle is released before
moving the bed, and secured once the bed is positioned.
Option 2:
The ‘Gap’ on the lathe bed (FIG. 22) can be filled
with RIKON’s Gap Bed Insert accessory (FIG. 24). This
short, duplication of the lathe’s upper lathe bed installs over
the exposed lower bed and continues the upper bed track
at the same height as the sliding bed. This means that your
tool rest base can be now positioned anywhere on the lathe
for turning, sliding from end-to-end, between center-to-
center. A second tool rest base is not needed.
NOTE:
The Gap Bed Insert #70-907 is sold separately.

THE SLIDING BED MOTOR ASSEMBLY
As instructed on page 13, the sliding bed’s position on the
lathe is set with a selector switch on the lathe’s control box.
This switch activates the lathe’s second DC 24V motor and
screw drive that is located under the sliding bed. Figure 25.
It is important that the sliding bed’s rear
locking handle (FIG. 19, page 13, #C4) is released before
the bed is moved, or excess stress to the DC motor assem-
bly and electrical circuitry will result. Once the sliding bed
is positioned where you want it for turning, secure the rear
locking handle to prevent the bed from moving during work.
If the sliding bed’s DC motor assembly ever fails, it can be
disconnected from the lathe. Simply disconnect the electri-
cal wires at the Molex® connector, and remove the 2 cotter
pins that hold the assembly ends in place under the sliding
bed’s frame. FIG. 25 & 26. The DC motor assembly can
then be removed from the lathe for replacement or repair.
Reverse the process to install the new/repaired DC motor
assembly.

ADJUSTMENTS
Remember,
the end handle is to be used ONLY when the
DC motor assembly is disconnected from the sliding bed to
move the sliding bed manually. It is not designed for lifting.
ALIGNING SPINDLE CENTERS
The alignment of the headstock spur center and the tail-
stock live center are set at the factory, but, this should be
checked once the lathe is assembled and ready for use.
1. Slide the tailstock towards the headstock until the center
point of the live center almost touches the headstock’s spur
center. Figure 28.
2. Check the alignment of the center points by viewing
from the top and side.
3. If the centers do not align, slightly loosen the 4 bolts that
secure the headstock to the bed. Carefully nudge the head-
stock to align the centers. Then fasten the 4 bolts to secure
the headstock in place.
