8.2 Tailstock
Refer to Figures 8-2 and 8-3:
Loosen locking lever (C) and slide tailstock into
position. Retighten locking lever.
Do not position edge of
tailstock off end of bed. This will reduce
clamping surface and may increase risk of
injury.
To remove tailstock, loosen lever (C) and slide
tailstock off end of bed.
Handle (D) locks and unlocks tailstock quill. (The
handle is adjustable – lift up on handle and rotate it
on pin, then release, making sure it seats itself on
the pin.)
Handwheel (E) advances and retracts quill.
NOTE: If quill is well advanced and won’t respond
to handwheel rotation, push quill toward
handwheel until it engages.
Figure 8-2
The clamping system has been properly adjusted
by the manufacturer. If in the future it does not
properly lock tailstock in position, remove tailstock
from bed, and turn it over. Adjust cam lock nut
(Figure 8-3) as needed.

8.3 Speed Change
Refer to Figures 8-4 and 8-5.
The lathe has six speeds, determined by which pair
of pulley steps is chosen. See Figure 8-4. A speed
chart is affixed to the inside of the upper access
door.
Figure 8-4
To move belt to a different pulley:
1. Open upper and lower pulley access doors.
2. Relieve belt tension by pulling handle (F,

3. Move belt to desired pulley set. Make sure belt
is properly seated in both pulleys, and both
pulleys are aligned (belt is vertical, not
slanted).
4. Push lever (G) down to tighten belt, and close
access doors.
Keep access doors closed
during operation.
