Speed Range Adjustment
(Refer to Fig. 11)
The lathe is designed having two speed ranges: Low Range: 60-1000 rpm and High
Range: 2000-3500 rpm.
In each range, the speed can be changed variably by the electronic variable speed
controller.
Follow the steps below to change the speed range:
1. Disconnect the lathe from the power supply;
2. Open the HeadStock Guard which is held by a strong magnetic pad;
3. Loosen the Motor Locking Handle “A”, pull up the Motor Mount Handle to release the belt
tension;
4. Position the belt on the desired speed range pulleys;
5. Turn the spindle hand wheel by hand, ensuring that the belt rotates smoothly and is
engaged with both the motor pulley and the spindle pulley;
6. Tighten the belt by pushing down the motor mount handle, then tighten the motor locking
handle “A”. Close the HeadStock Guard.

Note:
The best belt tension is determined by pressing the belt with one finger. The belt
should deflect about 1/4” -1/2” (about 6-12mm).
