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.
PRINCIPLES OF OPERATION
CAUTION! To prevent electric
shock, do not use power tools
near wet areas, or where power
tool may become wet.
Always wear eye protection while
using punching tools, or in the
vicinity of punching.
CAUTION! The slug is ejected at
the end of the punch. Do not aim
the unit so that ejected slug may
hit someone around, or below
you.
SAFETY FIRST
CAUTION! Risk of pinching or
crushing . Keep away from
moving parts when unit is
in use.

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 Die Selection and Proper Punches and
Dies on next page.
*If you are using the hole locator gauge, adjust it to the
proper distance. See Hole Locator Gauge Adjustment
on next page.
*Plug the power cord into the proper power supply.
OPERATING PROCEDURES
*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.
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.
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.
INSTRUCTIONS -- FOOT SWITCH
WARNING! Failure to check punch retaining nut periodically during use, can result in
personal injury or damage to the unit could occur.

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,
rst, 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).
HOLE LOCATOR GAUGE ADJUSTMENT
All models can be used with an accessory work stand for
bench or table mounting of the Hole Puncher. The stand
is standard with all models. To install the stand, rst
unplug the power cord., then mount the unit to the stand
with the supplied hardware.
When using the stand, periodically check to make sure that
the punched material (slugs) are not stacking up between
the exit hole in the "C"-frame and the stand. Keep this area
clear of accumulated slugs.
USING THE WORK STAND
SELECTING PROPER DIES
Proper die selection is essential. Other than the obvious
necessity of matching shaped punches and dies, there are
two other basic selection factors that must be considered.
The rst is die clearance. Different material types and
different material thicknesses require different clearances
between the punch and die. In order to maintain the best
possible hole while remaining within the tonnage
capacity of the machine, it is essential to choose the die
with the proper clearance. The second is the die angle.
Most structural shapes can be punched with the standard
at dies, but "I" -beams and most channels which
have a 2-in-12 taper require the use of special
9-1/2 degree angled dies. Car and ship channel
anges and other structural shapes with a 2 degree
taper can be punched with at dies. Materials with
a ange taper of less than 5 degrees can also be
punched with the at die, however, the hole will be
slightly angled. Refer to specic information and
tables within this manual for the proper punch and
die combination.
Hougen-Ogura Punches are designed to be used in
Structural Steel. If used in harder or higher tensile
strength materials, performance will be impeded and
serious damaged could occur to your unit.

NOTE: The internal components of the pump and piston area have very close clearances and are sensitive
to damage from dust, dirt, contamination of the hydraulic uid or improper handling. The disassembly of the
pump housing requires special tools and training, and should be attempted by a qualied repair person. The
improper servicing of electrical components can lead to conditions that could cause serious injury.
ANY ATTEMPT BY UNAUTHORIZED PERSONNEL TO SERVICE THE INTERNAL COMPONENTS OF
THE PUMP AREA WILL VOID THE WARRANTY.
In order to insure smoother operation and longer life of your
hole puncher, the following maintenance should be done
periodically, based on use.
1. Keep the machine clean. It is especially important to
keep the sliding portion of the punch piston free from metal
chips, scale, dirt, dust or other debris. To clean the punch
piston, turn on the switch to move the punch piston almost
to the bottom of its stroke. If necessary, cycle the punch
several times to determine where the bottom of the stroke
is, and to correctly position the punch piston.
Unplug the power cord. Wipe any debris from the ex-
posed part of the punch piston.
2. Regularly tighten all fasteners and replace any
worn components.
3. Check power cord, if cracked or frayed, return the
machine to an authorized repair center for
replacement.
4. Check oil level, carefully using the procedure below.
ADDING OIL
4. Carefully open the oil port by removing the socket
head cap screw.
5. Using the small squeeze bottle supplied with the
Hole Puncher, carefully add hydraulic oil to completely
ll the reservoir. Rock the Hole Puncher back and forth
slightly several times to free any trapped air bubbles,
then add additional oil if necessary.
6. Replace the cap screw and wipe up any excess oil.
7. Cycle the Hole Puncher several times with the
Manual return Valve open, and again with the valve
closed, to work any trapped air out of the system,
then repeat the above procedure, making sure that the
punch piston is almost at the bottom of the stroke
before removing the cap screw from the oil port.
8. Add additional oil as necessary. If the unit was
extremely low on oil, it may be necessary to repeat
the procedure several times.
MAINTENANCE
HELPFUL HINTS FOR HOLE PUNCHING
Each of the punches is provided with a sharp point at its
center. If the hole locations are center punched, the point
on the end of the punch may be used to "nd" the center
punched spot.
Also, for accurate and easy positioning of the punch to a
hole location, the switch can be intermittently pulsed on
an off to jog the punch down to the work surface.
If the position is not satisfactory, open the manual return
valve to retract the punch for another attempt. This
operation can also be performed with the manual return
valve "cracked" open slightly to prevent full punching
pressure from being developed. In this manner, the
punch can be easily brought right down to the surface
without beginning to punch the hole. If the location is
satidfactory, close the valve and nish the operation.
Use of the correct hydraulic oil is essential. Approved oils
are Shell "TELLUS Oil" and Exxon "TERESSTIC" (Part
No. 75377). Grade #32 viscosity must be used. Check the
unit specications. Make sure that the work area and all
equipment are clean so that no dirt, dust or other foreign
material can get into the hydraulic oil or pump area.
1. Locate the socket head cap screw that plugs the oil port.
It is just above the manual return lever on the right hand
side of the Hole Puncher.
2. Lay the Hole Puncher on its left side so that the oil port
is facing up.
3. Turn on the switch to move the punch piston almost
to the bottom of its stroke. If necessary, cycle the punch
several times to determine where the bottom of the stroke
is, and to correctly position the punch piston. In this posi-
tion, the maximum amount of oil has been drawn from the
pump and the correct ll can be obtained.
WARNING! Failure to check punch retaining nut periodically during use, can result in
personal injury or damage to your unit.
