Top Slide Handwheel
(U, Figure 9-2): Rotate
to position rest. The accompanying scale on
collar is graduated in 0.001 inch increments.

Tailstock Quill Lock
(V, Figure 9-3): Push
clockwise to lock sleeve; counterclockwise to
unlock.

Tailstock Quill Traverse Handwheel
(W,
Figure 9-3): Rotate clockwise to advance quill;
counterclockwise to retract. Fully retract quill to
eject a center or drill chuck.

Tailstock Clamping Lever
(X, Figure 9-3):
Push up to lock; down to unlock.

Foot Brake
(see Figure 4-1): For emergency
shutdown of all lathe functions. The connecting
rod mechanism is in the bed stand, and
activates a brake strap at the main motor.
(Caution: Lathe still has power.)
NOTE: The foot brake is not intended for normal
stopping of the lathe. Overuse can result in
premature wear of brake parts.
21.
Chuck Key Bracket
: The chuck key must be
placed within the bracket (Figure 9-4) for the
lathe to operate. A sensor in the bracket will
deactivate spindle if key is not present – this
prevents key from accidentally being left in the
chuck.

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 range 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 (O, Figure 9-2) should be at neutral
position.
If foot 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 10-1.
Figure 10-1
Avoid long workpiece extensions, as parts may
bend or fly off. See Figure 10-2. Use rests or the
tailstock for support.
