Adjusting the Depth Stop
To drill multiple holes at the same preset depth,
use the depth stop:
1. Use a pencil to mark the depth the bit will
drill into the workpiece (A, Figure 7).
2. With the drill bit in the chuck, lower down
feed handle to advance bit to your mark,see
Figure 7.
3. With your other hand, advance the lock nuts
(B, Figure 7) on the depth stop rod until they
are snug to the seat (C, Figure 7).
4. The drill bit will now advance to this point.
5. To release, advance the nuts counter-
clockwise to the top of the depth stop.
Changing Spindle Speeds
A spindle speed and belt arrangement chart are
found on the inside of the belt cover (D, Figure
8). Refer to this chart whenever changing
speeds. (A similar chart is shown in Figure 11.)
To change spindle speeds:
1. Unplug the machine from the power
source.
2. Loosen two bar knobs (E, Figure 8) found
on each side of the head assembly.
3. Rotate the tension adjuster (F, Figure 8) 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 (F. Figure 8) to
tension the belts.
6. Tighten two bar knobs (E, Figure 8). Belts
are properly tensioned when finger and
thumb pressure midway between the two
pulleys causes approximately 1/2”
deflection.
