SAFETY INSTRUCTION FOR ELECTRO HYDRAULIC HOLE PUNCHER
AWARNING
—
. 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 firmly fixed 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 be run for a few minutes at 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
Ogura.
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 specifications.
10. Remove and check the Carbon Brushes regularly. Replace them after 200 times of use. Carbon
Brushes with a length of about 6 mm 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.
A CAUTION
1. Do not cover or clog the motor air vents as this may cause the motor to overheat, resulting in
smoke, fire and explosion.
2.This tool is a hydraulic tool powered by electricity. When the temperature is low, hydraulic oil
may become solid and tool cannot perform well. Idle tool for a few minutes before use.
3. As the oil reservoir was filled before delivery, do not add oil unless the tool works abnormally.
4. When using an extension cord with the charger, it is recommended to use a cord with the cross
section below and with a length as short as possible. For charging outdoors, use a cab tyre
extension cord.

BATTERY CHARGE
Yellow
. Plug the battery charger into the proper AC voltage source.
Charging light will flash in green color repeatedly.
. Insert the battery cartage into charger until stops adjust-
ing to the guide of charger. Terminal cover of charger
can be opened with inserting and closed with pulling
out the battery cartridge.
. When the battery cartridge is inserted, the red charging
light will light up and charging will begin with a preset
brief melody sound coming out for assurance as to which
sound will come out to notify the completion of charging.
. With finish of charge, the charging light will charge from
red one to green one and the melody sound or buzzer
sound (a long deep) comes out to notify completion of
charge.
. If you leave the battery cartridge in the charger after the
charging cycle is complete, the charger will switch into
its “trickle charge (maintenance charge)” mode which
will last approximately 24 hours.
. Charging time varies by temperature (10°C (50°F) -
40°C (104°F)) that battery cartridge is charged at and
conditions of the battery cartridge, such as a battery car-
tridge which is new or has not been used for a long pe-
riod of time.
. After charging, remove the battery cartridge from the
charger and unplug the charger from the power source.
The battery charger is for charging OGURA-battery cartridge. Never use it for other purposes or for
other manufacturer's batteries.
If you charge a battery cartridge from a just-operated tool or battery cartridge which has been left in a
location exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait
for a while. Charging will begin after the battery cartridge is cooled by the cooling fan installed in the charger.
* If the charging light flashes alternately in green and red color, charging is not possible. The terminals
on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.

If the material is not properly supported, it will move when
the Punch tries to return causing the Punch to jam and
damaging the tool.

Caution when selecting the Die
It is important that the Die selected is correct for the
thickness of the material to be punched.
Punching material of thickness 4 mm to 8 mm using a
Die for thinner material can cause the Punch to jam in
the material. This is due to the smaller clearance bet-
ween the Die and Punch. In such a case the material
will be pulled up by the retracting Punch as shown in
the drawing on the left. Special care should be taken
when punching flat bar of mild steel, aluminum and
К copper.
The difference between the old and new Die
Material
The Dies used with the N series are a new design and are not interchangeable with the older style Dies.
A WARNING
The old design Dies cannnot be used with the N
series. Using the older style Dies with the N series
may result in serious injury.
= = Use only the correct Dies installed according to
+ the instructions in this manual.

OPERATING PROCEDURE
How to operate the Trigger Switch and the Switch Lock
Switch Lock
Trigger Switch
Rotating Function of Motor
A WARNING
Before the Battery is inserted into the Motor, pull
and release the Trigger Switch to ensure that the
Trigger returns when released.
- If the Trigger Switch does not work correctly it
- The motor is on when the Trigger Switch is pulled
may cause an accident.
and off when the Trigger Switch is released.
How to use the Switch Lock
- Push in the Switch Lock on side A. The Switch is
un-locked and the Trigger can be pulled.
- Push in the Switch Lock on side B. The Switch is
locked and the Trigger cannot be pulled.
A CAUTION
The Trigger Switch should be locked at all times
when not in use.
The Motor Body can be rotated though 360 degrees, in
either direction, during operation. This feature is particularly
useful when working in awkward or narrow areas as it allows
the operator to position the tool in the best position for easy
operation.
CARBON BRUSHES REPLACEMENT PROCEDURE
When the carbon brushes become less than 6mm the motor force deteriorates because of low rectification.
Carbon brushes need to be replaced.
1. Remove the carbon brush cap of the motor outer frame using the standard screwdriver.
2. Replace the carbon brushes with new ones.
3. Put back the caps.

MAINTENANCE
CAUTION
Keep the air hole at the end of the C Frame clear of dirt
and obstructions. The air hole has to be open in order to
control the hydraulic pressure.
Air Hole
Do not undo or remove the three screws in the drawing
on the left. Doing so will cause oil to leak from the tool.

ADDING OIL
This Hole Puncher is electro-hydraulic. When shipped from the factory, it was filled with the oil. Do not atte-
mpt to add oil as long as the tool performs well. When the oil-pressure is not enough for proper operation add
oil as follows. Make sure that the work area and all equipment is 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. Operate the tool 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 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 fill can be
obtained. Disconnect the tool from its power source.
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 fill
the reservoir. Rock the Hole Puncher back and forth slightly several times to free any trapped air bubbles,
then add additional oil as 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.
A CAUTION
Only pure hydraulic oil as recommended by Ogura & Company Ltd., should be used in this tool.
Recommended oils include the Ogura supplied hydraulic oil, Super Hyrando #46 (JX Nippon
Oil & Energy Corp.); 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 int-
ernal machine parts.

NOTE: The internal components of the pump have very close clearances and are sensitive to damage
from dust, dirt, contamination of the hydraulic fluid or improper handling. The disassembly of the
pump housing requires special tools and training, and should only be attempted by repair personnel
who have been properly trained and have the proper equipment. The improper servicing of electrical
components can lead to conditions that could cause serious injury. The pump and piston components
and all electrical components should be serviced only by authorized repair shop, dealer or distributor.
Any attempt by unauthorized personnel to service the internal
components of the pump area will void the warranty.
