The half nut is correctly adjusted when it has a slight
drag while opening and closing.
5. The movement should not be too stiff or too
sloppy.

Feedrod Clutch Adjustment
This lathe has an adjustable feed clutch that helps
protect the drivetrain from overload.
The feed clutch release point is adjusted at the factory.
However, it can be be easily adjusted depending on
operator requirements.
To adjust the clutch release point :
1. Disconnect Lathe from POWER !
2. Remove the front and side feed access covers,
as shown in Figure 93.
4. Insert the hex wrench into the collar adjustment
hole shown in Figure 95, and use the wrench to
rotate the clutch collar.

with the closest set screw slot that is cut into the
feedrod (see Figure 95).
6. Install and tighten the set screw so it is fully
seated in the slot.

V-Belts
V-belts stretch and wear with use, so they should be
checked on a monthly basis to ensure optimal power
transmission. Replace all the V-belts if any of them
show signs of glazing, fraying, or cracking.
To adjust or replace the V-belts on the lathe :
1. Disconnect Lathe from POWER !
2. Remove the cover shown in Figure 96.
3. Turn the hex nuts on the motor mount bolts
shown in Figure 97 to move the motor mount
plate up or down and adjust the V-belt tension.
When correctly tensioned, each belt should have
about 19mm de
fl
ection when pressed
fi
rmly (see
Figure 97).
