Important Safety Instructions
1. Proper selection of the punch and the die is essential. Select the correct punch and die according to
the hole shape, size of hole, material thickness and material type.
2. Ensure that any punch with stepped edge to prevent free rotation is installed correctly in the punch
piston before tightening the punch retaining nut.
3. For punching channel and stainless steel, use the die provided exclusively for these materials. Only
select a suitable punch & die combination that is correct for the material thickness.
4. Ensure the punch and the die are rmly xed in position with the nut or the bolt. Failure to do so may
cause serious damage to your tool and serious personal injury. Regularly check and tighten the punch
and die.
5. The tool is electro-hydraulic. When the temperature is cold it should run for a few minutes and idle
before starting operations.
6. Keep face, hands and other parts of the body away from the punching area during operation.
7. Remove battery before changing the punch and the die or when servicing or making adjustments.
8. The punch and the die that become worn, deformed, nicked, broken or damaged in any way may
cause a tool breakdown and a serious accident. Replace them immediately with new ones supplied
from Hougen Manufacturing, Inc.
9. When punching stainless steel, the punch and die may wear earlier than would be the case with softer
materials. Ensure that the punch and die are in good condition, free from wear and are not deformed,
nicked, broken or damaged in any way. Check with your dealer before punching any material not listed
in the specications.
10. Remove and check the carbon brushes regularly. Replace them after 200 times of uses. Carbon
brushes with a length of about 6mm or less may cause damage to the motor.
11. When using the tool continuously, its temperature can exceed 70 degrees, which may cause lower
performance. In this case, stop operating for about 1 hour to allow the tool to cool down before
using it again.

die. Remove the set bolt and the nut securing the
punch and the die. Insert the hex wrench supplied
through the hole of the stripper and undo the set
bolt. The set bolt can be released without
removing the stripper.
Note: When replacing the punch and the die
make sure that the correct size, thickness
and hole shape is selected. Shaped
punches and dies must be properly
aligned with each other.
3. The die must be installed rst. Place it in the
C-frame in the proper orientation. Secure rmly
with the set bolt and tighten the nut.
4. Insert the new punch into the punch piston.
Secure rmly with the set bolt and tighten the nut
to prevent the set bolt from coming loose.
Note: When installing a punch with a stepped
edge (anti rotation), make sure the
orientation is correct and that the
stepped edge is correctly positioned in
the punch piston.
5. Replace the stripper.
WarnInG
Make sure that the punch is seated properly in
the punch piston. Failure to do so may cause
serious damage to the tool and may cause
personal injury. When installing the oblong
punch, make sure the orientation is correct and
that the stepped edge of the punch is correctly
positioned in the punch piston before
securing it with the set bolt and nut.
For punching anges (llets) in channel
steels, use the die with a beveled edge.
Using the wrong die may cause serious
damage to the tool, punch and die.
The locating pin which is supplied with the
oblong punch can not be used with the Model
76000. Use the punch without installing the

ADDING OIL
The Cordless Hole Puncher is electro-hydraulic. When shipped from the factory, it was lled with oil. Do not
attempt to add oil as long as the tool performs well. When the oil-pressure is not enough for the operation,
add the oil as follows. 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 position 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 position, the maximum amount of oil has been drawn from the pump and the correct ll can
be obtained.
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. Lock the Hole Puncher back and forth 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 its 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.
CautIon
• Only pure hydraulic oil should be used in this tool. Recommended oils include the
supplied hydraulic oil, Super Hyrando #46 (Nippon Oil Corporation); Shell Tellus Plus
#46 (U.S. Shell); or equivalent spec anti-wear hydraulic oil, ISO Viscosity Grade 46.
Do not use other oils as these may cause damage to the seals and other internal
machine parts.
• Keep the air hole at the end of the C Frame clear of dirt. The air hole should be open
for controlling the hydraulic pressure.
