7.6 Drill Stop Switch
The Drill Stop Switch consists of a magnet (no wires) mounted near a magnetic reed switch (with
wires) mounted inside the machine case near the Safety Buttons. (Fig 28) At the full extension
of the drilling stroke, the carriage interrupts this switch to signal the end of the drilling stroke and
the end of the cycle. If the clamp doesn’t release and the pilot drill won’t retract, then the
magnet is too close to the reed switch.

• Turn the power to the machine off.
• Remove the Work Top
• Loosen, but do not remove, the screws (Fig 29) that secure the magnet and the reed switch
to the machine case (you may need to remove a portion the laminate strip on the front of the
machine to access the mounting screws). Although the mounts are not slotted, spread the
magnet and the reed switch as far from each other as possible, then retighten the screws.
