Adjusting the Depth Stop

To drill multiple holes at the same preset depth, use the depth stop:

1.Lower the bit until it touches the workpiece.

2.Loosen lock knob (A, Fig. 7) and rotate housing (B, Fig. 7) until the pointer lines up with the depth you want to drill, indicated by the scale.

3.Tighten lock knob.

4.The drill bit will now advance to this depth.

Changing Spindle Speeds

A spindle speed and belt arrangement chart are found on the inside of the belt cover, see Figure

8.Refer to this chart whenever changing speeds.

To change spindle speeds:

1.Unplug the machine from the power source.

2.Loosen two bar knobs (C, Fig. 9) found on each side of the head assembly.

3.Rotate the tension adjuster (D, Fig. 9) to bring the motor base as close to the head as possible.

4.Change the belts location according the speed chart and the speed you desire.

5.Rotate the tension adjuster (D. Fig. 9) to tension the belts.

6.Tighten two bar knobs (C, Fig. 9). Belts are properly tensioned when finger and thumb pressure midway between the two pulleys causes approximately ½” deflection.
