22. Tailstock Off-Set Adjustment (D, Figure 17):
Two hex socket cap screws located on the
tailstock base are used to off-set the tailstock
for cutting tapers. Loosening one screw while
tightening the other will off-set the tailstock. Do
not clamp the tailstock lock handle when
adjusting.

23. Foot Brake (A, Figure 18): The connecting rod
mechanism is in the bed stand. The braking
device is in the pulley of the headstock. Press
the pedal to stop all lathe functions. (Caution:
Lathe still has power.)
24. Micro Carriage Stop (B, Figure 18): can be
used during manual feed operation. The dial
can be turned for fine tuning the position of the
stop. The micro carriage stop can be moved
along the bed by loosening the two socket
head cap screws underneath the stop.
25. Bed Cover (C, Figure 18): can be easily
removed to clean out the stand.
13.0 Operation
The operator should consult shop manuals such as
“Machinery’s Handbook” for cutting speeds and
feeds appropriate to specific workpieces. Correct
feed depends upon material to be cut, cutting
operation, tool type, chucking rigidity, depth of cut,
and desired surface quality.
IMPORTANT: Allow a break-in period for the new
lathe so that gears and bearings can adapt; do not
run the lathe above 560 RPM for the first six hours
of operation.
The following points must be
observed when operating the lathe:
• Never turn any handles or levers when spindle
is at high speed.
• Change spindle speed only after spindle stops.
• Change feed rate only when spindle is at low
speed or is stopped.
• Never exceed maximum speed limitation of the
work holding device.
• Before starting spindle, check that each handle
or lever is at correct position to ensure normal
engagement of gears. The spindle direction
control lever should be at neutral position.
• If the brake becomes ineffective, turn off
machine and adjust brake immediately.
• When operating spindle direction control lever,
always turn it to correct position; never use
“pre-position” for cutting at a reduced speed.
• Jaw teeth and scroll must be fully engaged, to
prevent the jaws from breaking and being
thrown from chuck (see Figure 19).
Figure 19 – Insufficient jaw tooth engagement
• Avoid long workpiece extensions, as parts may
bend or fly off (see figure 20). Use rests or the
tailstock for support.
Figure 20 – Improper setups
• Avoid short clamping contact (Figure 21, A) or
clamping on a minor part diameter (Figure 21,
B). Face-locate the workpiece for added
support.
