your hands are inside the headstock.
Tip: When rotating the adjustment ring, hold
the adjustment ring stationary and rotate the
input pulley to make the adjustment.
Continue loosening and testing until the
lever engages the troublesome position.
When you are satisfied with the loosened
setting, slide the adjustment ring towards
its clutch assembly to lock it in position (see

the clutch adjustment procedure as needed.

Do not attempt to over-tighten the clutch
to reduce spin-up time. 3-4 seconds is the
normal time required for the spindle to reach
full speed. Overtightening the clutch may
result in damage and improper lathe function.
