4. When returning table to horizontal position,
loosen handle (E) and bolt (D), tilt table back
to zero degrees on scale, and tighten handle
(E), then tighten bolt (D).

8.2 Chuck and arbor removal
Referring to Figure 18:
1. Disconnect machine from power source.
2. Lower quill assembly with the downfeed
handles to expose slot. Rotate chuck to align
slots.
3. Insert drift key into slot.
4. Tap drift key into slot until chuck and arbor fall
out. NOTE: Hold on to chuck to prevent it
being damaged as it falls.

8.3 Changing spindle speeds
Change speeds only while drill
press is running.
With the drill press running, rotate handwheel
(shown in Figure 9) until desired speed is displayed
on LED readout at front of head. Speed range is
250 to 3000 RPM.
8.4 Depth stop
The depth stop is useful for repetitive drilling of
holes of identical depth.
Referring to Figure 19:
1. Measure distance from tip of drill bit to
workpiece. Add to this the desired depth of
hole in workpiece.
2. Position top nut (F
1
) so that its bottom edge
aligns with this measurement on the scale.
Note: For quick positioning, press button on
nut and slide into position; for fine adjustment
rotate nut along scale.
3. For less precise drilling, simply lower bit to
desired depth, as shown in Figure 19, and
slide top nut down to contact collar.
4. The lower nut (F
2
) can be used to hold the
spindle at a certain depth. Position the lower
nut up against the collar. The spindle will stop
at this position when the downfeed handle is
released.

8.5 Work stop
The work stop (G, Figure 19) is used for repetitive
drilling in boards of identical length. Flip up the
work stop to slide it along the fence or to remove it.
Pull it down to tighten in position.
8.6 Return spring
The tension of the return spring (which raises the
spindle after drilling) has been pre-set by the
manufacturer. No further adjustment should be
attempted unless absolutely necessary. Should it
become necessary, proceed as follows.
