5. Insert jaw #1 into jaw guide and hold jaw
against scroll-gear.
Rotate chuck key clockwise one turn to
engage tip of scroll-gear lead thread into
jaw. Pull jaw; it should be locked into jaw
guide.
6. Install remaining jaws in numerical
order, in same manner. The jaws should
converge evenly at center of chuck.
If jaws do not converge evenly, remove
them. Re-install jaws sequentially 1–3,
make sure each one engages with scroll-
gear lead thread during its fi rst rotation.
Tailstock Fig: 18
The tailstock is typically used to support long
workpieces at the side opposite the spindle,
using a live or dead center. It can also hold a
tapered drill bit for boring holes.
Positioning Tailstock
1. Rotate tailstock lock lever clockwise
(facing machine) to unlock tailstock from
bedways.
2. Slide tailstock to desired position by
pushing it along the bedways.
3. Rotate
tailstock
counterclockwise

Spindle Speed Fig. 20
Using the correct spindle speed is important for
getting safe and satisfactory results, as well as
maximizing tool life.
Setting Spindle Speed Range Fig. 21
The high/low range lever is used to select one
of the two spindle speed ranges.
When the lever is moved to the right, the low
speed range (0-1100rpm) is selected. When the
level is m- oved to the left, the high speed range
(0-2500rpm) is selected.
The carriage handwheel moves the carriage left
or right along the bed.
Setting Spindle Direction & Speed
Set the spindle rotation direction to forward or
reverse with the spindle direction switch. Turn
on the machine then turn the speed adjusted
knob clockwise until the desired spindle speed
display on speed di- splay.
Confi guration Example
Follow this example to gain a better understanding
of how to set the spindle speed.
To set spindle speed to 100rpm:
1. Make sure spindle is completely stopped,
and shift high/low range lever to low.
Note: if high/low range lever does
not easily adjust into position, rotate
chuck by hand while you apply
pressure to lever. When gears align,
the lever will easily move into place
2. Turn variable speed dial to "0"
