A power plug is not provided with the drill press.
You may either connect the proper UL/CSA
listed plug, or "hard-wire" the machine directly to
a service panel, provided there is a disconnect
near the machine for the operator. During hard-
wiring of the machine, make sure the fuses have
been removed or the breakers have been
tripped in the circuit to which the drill press will
be connected. Place a warning placard on the
fuse holder or circuit breaker to prevent it being
turned on while the machine is being wired.
When the 3-phase model is properly wired, the
spindle turns clockwise in a conventional drilling
rotation. If the spindle rotates the wrong
direction,
disconnect the machine from power
and switch any two of the three incoming leads.
Consult the electrical diagrams on pages 22-24
for further clarification of wiring.
This machine must be grounded. Grounding
provides a path of least resistance to help divert
current away from the operator in case of
electrical malfunction.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the machine.
Extension Cords
For circuits which are far away from the
electrical service box, the wire size must be
increased in order to deliver ample voltage to
the motor. An undersized cord will cause a drop
in line voltage resulting in loss of power and
overheating.
The chart in Figure 3 shows the recommended
size cord to use for branch circuits and
extension cords. The smaller the gauge number
the heavier the cord. If in doubt, use the next
heavier wire gauge.
Operating Controls
(Figure 4)
The keyed On/Off Switch activates power to
the drill press, and can be locked in the OFF
position to prevent unauthorized use.
The Selector Switch is used to determine
direction of spindle rotation (Fwd/Rev) and to set
the speed range (1 or 2).
The Emergency Stop button is for fast shut
down of drilling operations. Before re-starting
the drill press, rotate the emergency stop button
clockwise until it disengages. NOTE: Use the
basic stop button for normal stoppage of drill
rotation.
