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.
