Depth Stop
The depth stop is useful for repetitive drilling of
holes of the same depth.
Referring to Figure 19:
1. Measure the distance from the tip of the drill
bit to the workpiece. Add to this the desired
depth of the hole in the workpiece.
2. Rotate the bottom nut (A, Figure 19) to this
measurement on the accompanying scale.
3. Bring the top nut (B, Figure 19) flush with
the bottom nut. This will prevent any
movement of the bottom nut as it contacts
the seat (C, Figure 19).
Alternatively, for less precise drilling, you can
lower the bit to the desired depth, as shown in
Figure 19, and tighten both nuts (A and B)
against the seat (C).
Return Spring
The tension of the return spring (which raises
the spindle after drilling) has been pre-set at the
factory. No further adjustment should be
attempted unless absolutely necessary. Should
it become necessary, proceed as follows.
Referring to Figure 20:
1. Disconnect machine from power source.
2. Pry off the cap (A, Figure 20) and remove
the hex nut and two washers (B). Pull off the
hub (C).
3. Loosen the two inner hex nuts (D) Do not
remove.
4. Pull out slightly the coil spring cover (E)
while firmly holding it. DO NOT allow the
coil spring cover to turn freely in your
hand, or the spring will unwind.
5. Rotate the coil spring cover until the tab (F)
on the spring retainer engages the next
notch in the coil spring cover. Rotate the coil
spring cover counterclockwise to increase
spring tension, clockwise to decrease.
6. Make sure the coil spring cover is pushed
back in, then tighten the two hex nuts (D).
Do not over tighten. The hex nuts should be
tightened against each other.
7. Re-install hub, washers, hex nut and cap.
Start/Stop
Power Indicator Light – The start switch has a
power indicator lamp which is on whenever
there is power connected to the Drill Press,
not just when the Drill Press is running.
