Presetting the speed
The speed dial
allows you to adjust the opera-
3a
ting speed to specific speeds.
Which speed is most suitable depends on the
material you will be working on. We recommend
testing the speed to determine the correct setting.
Tip: These two basic rules about speeds
are always helpful:
1. larger bore diameter = lower speed and vice
versa, smaller bore diameter = higher speed
2. hard material = low speed
