stopped, but the machine still has power.
Drilling Tapping Selector (B, Figure 9A) For drilling,
press the start switch (F, Figure 9A) to run the machine.
Caution: The internal depth stop (GHD-20PFT) is used
only with the tapping function. Raise the adjusting knob
(B, Figure 11) to the top of the depth stop screw so as
not to interfere with power downfeed or manual feeding
operations. For tapping, turn switch (B, Figure 9A) to

functions when upper limit switch is released. It then
reverses automatically after hitting lower limit switch and
will not stop until it hits the upper limit switch.

stop all operations.
Power Light (D, Figure 9A) Indicates power is on.
Reverse Switch (E, Figure 9A) If tapping is interrupted
press the reverse switch to reverse the tap from

reversing.

Electrical Connections
Electrical connections must be
made by a qualified electrician in compliance with all
relevant codes. This machine must be properly
grounded to help prevent electrical shock and
possible fatal injury. All adjustments or repairs must
be done with the drill disconnected from the power
source.
The motor is rated at 2 HP, 3 PH, 230V only. Make sure
the power available matches the power requirement of
the drill. The drill must be properly grounded.
When the drill is connected properly, the spindle turns
clockwise in a conventional drilling rotation. If the spindle
does not turn clockwise, disconnect the drill from the
power supply and reverse two of the three power leads.
