4.5 CHANGING SPINDLE SPEEDS(FIG.13)
- The lathe features three step motor and headstock spindle 
pulleys. These three drive ratios are used in conjunction with the 
electronic variable speed control to provide maximum power and 
speed when required.
- Open both motor pulley and Headstock pulley access doors.
 Loosen motor locking arm and raise motor.
 Move drive belt to selected drive ratio.
 Lower motor for adequate belt tension and tighten locking arm.
 (Do not apply excessive load onto the belt prior to locking, as 
damage may result.)
- 
High ratio range - (small diameter Headstock pulley / large
diameter motor pulley) This ratio is for faster speeds - eg. 
Spindle turning and small Faceplate projects.
- 
Medium ratio range - (center Headstock / Motor Pulley
diameters) This ratio is suitable for most general woodturning 
work such as Spindle and Faceplate projects.
- 
Low ratio range - (large diameter Headstock pulley / small
diameter motor pulley) This range will provide maximum lower 
speed power ideally suited for larger Bowl turning projects.
- Once the desired ratio has been selected, firstly ensure the 
project is fixed to the machine in a strong and safe manner and 
fully supported by the Tailstock where possible.
Make sure the speed control knob is set on the slowest "o" 
position.
The machine can now be started with the speed control knob 
being slowly increased until a suitable and safe cutting speed is 
achieved.
NOTE:
For operator safety, always return speed control knob to "O" 
position when stopping the machine.
