ADJUSTMENTS
1. Unplug the lathe from the power source.
2. Remove the front Belt Door (#B54) to gain access to
the belt and pulleys that are inside of the headstock.
3. Loosen the motor mount Locking Hex Head Screws
(#B37 & B36, FIG. 10, A).
4. Lift the Tensioning Handle (#B40, B) to loosen the
tension on the Poly V-Belt (#B24). The belt can now be
positioned on the pulleys for the desired speed range.
FIG. 11 shows the belt positions for the two speeds.
NOTE: The ‘High’ speed range (0-3200 RPM) provides
maximum speed. The ‘Low’ speed range (0-1200 RPM)
will provide maximum torque. See the Speed Chart on
page 10, FIG. 6, for recommended speeds based on the
diameter of the workpieces being turned.
4. With the Poly V-Belt positioned on the pulleys, lower
the tensioning handle so that the weight of the motor
provides the needed tension on the belt. Then secure the
locking handle in place by re-tightening the two hex head
screws that were loosened in step 3, above.
5. Re-attach the front Belt Door onto the headstock to
protect the belt, pulleys and internal working from dust.
NOTE: The AC Inverter (#B18), located on the rear of
the headstock, does not require any programming. It
is pre-programmed from the factory. The buttons and
knob on the face of inverter should not be changed.
Use only the controls on the front of headstock.

CHANGING SPEEDS
THE MACHINE MUST NOT BE
PLUGGED IN AND THE POWER SWITCH MUST BE IN THE
OFF POSITION UNTIL ALL ADJUSTMENTS ARE COMPLETE.
ADJUSTING THE LOCKING HANDLES
The locking handles on the tailstock, tool rest and head-
stock are pre-set at the factory to give ample holding pres-
sure against the lathe bed to keep these lathe assemblies
positioned, so that they will not move during use.
If adjustments are needed, the clamping pressure can be
changed by turning the large Hex Nuts (#A26, B41) that are
located under the lathe bed and below the assemblies. This
can be done with an adjustable wrench (not included).
FIG. 12 shows the tool rest removed from the lathe bed.
1. Loosen the locking handle so that there is no clamping
pressure being exerted on the lathe assembly.
2. With the wrench, slightly turn the Hex Nut to loosen or
tighten it on its threaded Clamping Bolt (#A4, A13, B43).
3. Test the clamping pressure with the locking handle, and
adjust the nut again, if needed, to set the right pressure.
