Changing Spindle Speeds
The Woodfast lathe features five step motor and
spindle pulleys (A-Fig. 22) to provide five different
spindle speed ranges. Open the access covers on
the headstock and stand to change spindle
speeds.(See Fig.22)
With access covers open, loosen the motor plate.
Raise the motor to release tension on the pulleys.
Check speed and belt position chart on the
headstock to determine spindle speed required.
(See Fig.23)
Move drive belt to desired pulley combination.
Lower the motor plate, the weight of the motor will
provide proper tension on the drive belt. Tighten the
motor plate and close access covers.

Variable Speed Switch
In conjuntion with the five speed pulley system, the
Woodfast lathe also features a variable speed
switch. To use with in a specific belt speed range,
simply turn the lathe on (A-Fig. 24) and rotate the
variable speed dial (B-Fig. 24) clockwise to
increase the speed, and counter clockwise to
decrease the speed. The spindle speed will be
indicated on the digital readout (C-Fig. 24).
Note: The variable speed dial will only increase
speed to the highest speed shown depending on
belt position. (See Fig.23)
