Half Nut Lever
The half nut lever locks the half nuts around the lead screw, which engages the carriage drive for
threading.
The half nuts are engaged when this lever is to the right and disengaged when this lever is to the
left.
CAUTION: Do not engage the half nuts for any turning or facing operation.

Tip: Don
’
t try to engage the half nuts when the power feed is engaged. There
’
s an
interlock, but you can break it if you try.
You’ll find it easier to engage or disengage the half nuts while the lathe is running. If you do
attempt to change when the lathe is stopped, don’t force it.
Power Feed Lever
The power feed lever engages the carriage drive when it is down, and the cross slide drive when it
is up. Power feed is disengaged in the middle position. Push the lever to the left before moving it
up or down.

The tailstock is locked into position on the ways by the tailstock locking lever on the back of the
tailstock. Pull the lever toward you to tighten the tailstock lock. Push the lever back to release
the tailstock.
Tailstock Quill Hand Wheel
The tailstock quill hand wheel moves the tailstock quill in and out. There are (mm) graduations on

wheel dial.
Retract the tailstock quill all the way to remove tools from the taper in the tailstock quill.
Tailstock Quill Digital Position Readout (Model 7550 only)
The HiTorque Deluxe Bench Lathe has a digital readout on the tailstock that displays the quill
position more precisely than the graduated markings on the standard model. Operation of the
tailstock readout is the same as those for th
