Setting a Drilling Depth
Located on the left side of the Headstock is the depth feed
adjustment assembly, which allows drilling a series of holes
to the same depth using one setting.
1. Lower the drill (with the power OFF) so that it contacts
the material and hold in that position.
2. Screw down the lower Adjustment Nut (65) on the Stop
Rod (64) until the gap between the underside of
the Nut and the Drill Stop face equals the depth of
the hole required.
3. Screw down the upper Adjustment Nut against
the lower Adjustment Nut to lock setting.
Note: Alternatively, drilling depth for a one-time
procedure can be determined by lowering the drill (with
the power OFF) until it contacts the work, noting
the position of the Pointer (63) on the Scale, turning
the drill ON, and drilling to the required depth using
the Scale as a guide.

Changing Drill Speed
Before changing drill speeds, make sure the machine
is switched OFF and UNPLUGGED.
1. Open the Pulley Cover.
2. Loosen the Motor Tension Knob (42) on the Headstock,
and move the Motor (14) towards the Headstock to
relieve tension on the V-Belt (45).

3. Consult the chart below and position the V-Belt on
the Pulleys (2, 17) according to the desired drill speed.
4. When the Belt has been correctly positioned, tighten it
by pushing the Motor away from the Headstock until
the Belt deflects by approximately 1/2" at its center
when using reasonable thumb pressure. Lock this
position in with the Motor Tension Knob.
