The Hougen-Ogura Electro-hydraulic Hole Puncher is an
integrated unit, containing the electric motor, hydraulic pump,
and"C"-frame punching unit. It uses hydraulic power to force the
punch through the workpiece, and a strong spring to return the
punch piston to its "home" position. The patented design includes
an automatic valve that releases the hydraulic pressure when the
punch piston is at the bottom of its stroke. The automatic valve
remains open until the punch piston has fully returned to the
home position.
As a result of this design, the piston will not return to its
home position automatically unless the full stroke has been
completed. Also, the punch will not begin another stroke
unless the punch has fully returned to the home position,
resetting the automatic valve. To allow the punch piston to be
manually returned in the event that the punch cycle is stopped
prior to completion, a manual return valve is provided.
Read, understand and follow all safety instructions and
operating procedures. If you do not understand the
instructions or if conditions are not correct for proper
operation, do not operate the machine. Consult your
supervisor or other responsible person.
*Check that the trigger switch is not locked on.
*Check that the manual return valve is closed.
*Make sure that the proper punch and die are installed
correctly. (SEE PAGE 5) See Die Selection and Proper
Punches and Dies (SEE PAGE 9)
*If you are using the hole locator gauge, adjust it to the
proper distance. See Hole Locator Gauge Adjustment
below.
*Plug the power cord into the proper power supply.
INSTRUCTIONS -- FOOT SWITCH
Although the foot switch is guarded against inadvertent
operation, it is best to position the foot pedal away from
normal standing position. Place it in a position that
requires deliberate effort to reach and activate the switch.
HOLE LOCATOR GAUGE ADJUSTMENT
The Hole locator Gauge can be set to hold the Hole
Punches at a constant distance from the edge of the
workpiece. The gauge is held in place by one or two
socket head caps screws. Before making any adjustment,

*Position the puncher at the proper location on the
workpiece using the hole locator gauge or by locating the
point on the end of the punch into a center punch mark on
the piece.
With everything in proper order, the switch can be activated
to start the electric motor. The punch piston will move out
and push the punch through the material. Keep the switch
on until the punch has reached the end of its stroke and
stops. Release the switch. The automatic return valve will
open at the end of the stroke allowing the punch piston to
retract to its home position. The punch piston must return
completely before another hole can be punched.
If the punch stops in the midst of its stroke or does not
come out of the material, open the manual return valve.
Once the punch piston has returned to its home position,
tighten the manual return valve.
The trigger switch should be locked on only when ready
to punch. Release the trigger switch immediately after
punching to prevent operation by inadvertent actuation
of the foot switch.
first, unplug the power cord. To adjust the position of the
gauge, loosen the cap screw(s), tap the gauge into the
desired position and retighten the cap screw(s).
