Cutting Speed
Blade speed selection should be made according to the material being cut. In general, the harder the material the slower the blade speed. The chart in Figure 12 provides a general reference.

Figure 11. Cutting speeds and pulley selection.
The speed is changed by moving the V-belt onto the different sized pulleys on the motor and the saw. See Figure 12.
1.Remove the belt guard.
2.Loosen the motor tension knob.
3.Pull the motor over to relieve the belt tension. Move the belt to one of the four desired locations according to the speed chart. Never cross the belt so it is diagonal across the pulleys.
4.Tighten the motor tension knob.
5.Replace the belt guard.

DO NOT attempt to assemble, adjust, or maintain this machine while it is running. Turn off the switch, disconnect the bandsaw from its power source and wait for all moving parts to come to a complete stop before attempting any adjustments or main- tenance. Failure to do so could result in serious injury.
