4.10 Variable Speed Switch
1. In conjunction with the six speed pulley system, the lathe also features
a variable speed control. To use with in a specific belt speed range, simply
turn the lathe on by pressing the green button (A-Fig.4.12) and rotate the
variable speed control knob (B-Fig.4.12) clockwise to increase the speed, and
counter clockwise to decrease the speed. To turn the lathe off press the red
stop button (C-Fig.4.12).
If you wish to put the lathe into reverse simply turn the motor direction knob
(D-Fig.1.12) to the right.
Please note: The reverse switch must only be used when the
machine is switched off.
2. The variable speed dial will only increase speed to the highest speed
shown depending on belt position. (Fig.4.13).
Caution: Most turning can be safely and effectively achieved
between 400 and 2000 rpm. The additional speeds achievable
with this unit are for specialist turning such as high speeds for
miniature work, pens and lace bobbins and slow speeds for
thread cutting for example. These speeds are only to be used
by experienced turners who have had adequate training and
observe all recommended safety and operating procedures.
Pulley Speed Ranges (Fig.4.13)
By changing the belt on to each of the six different pulleys the speed can be
varied from 50 rpm to 3850 rpm.
Please note: When using the revering function, be aware that any
accessories fitted to the headstock spindle thread may become
loose as the direction of rotation will be the same as the thread,
only use accessories that feature an additional looking function
(such as a grub screw etc) and do not rely on the spindle thread
alone to secure them to the lathe.
