Changing RPM
Figure 18. RPM dial.
The variable speed dial shown in Figure 18 controls the
spindle speed and the pulleys shown in Figure 19 control
the speed range. As a general rule, smaller bits and
softer material require higher speeds and less torque,
and larger bits and harder materials require slower
speeds and greater torque.
To change the RPM, do these steps:
1. Turn the mill ON and rotate the RPM dial (Figure
18) to reach the desired speed.
To change speed range, do these steps:
1. Remove the pulley cover and loosen the motor
mount nuts shown in Figure 19.
2. Slide the motor pulley toward the spindle pulley and
move the round belt to the other pulley position.
Note: The upper pulley position is the low range,
and the lower pulley position is the high range.

Depth Stop
Figure 17. Depth stop.
The depth stop allows the operator to make numerous
holes that all are the same depth or to hold the mill at a
specified depth.
To set the depth stop, do these steps:
1. Use the micro downfeed knob to set the desired
depth.
2. To set the quill to repeat the same depth, rotate
the graduated dial ( Figure 17) past the O mark until
it stops, then tighten the set screw.
3. To lock the quill at the specified depth, rotate the
graduated dial past the 30 mark until it stops, then
tighten the set screw.
