Important Safety Instructions

WarnInG

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.

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.

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.

OBLONG PUNCH PROCEDURE

The locating pin which is supplied with the oblong punch can not be used with the Model

76000. Use the punch without installing the locating pin.

BATTERY CHARGE

1. Plug the battery charger into the proper AC voltage source. Charging light will ash

in green color repeatedly.

2. Insert the battery cartridge into charger. The terminal cover of the charger can be opened when inserting and closed when removing the battery cartridge.

3. When the battery cartridge is inserted, the red charging light will light up and charging will begin.

4. When the battery is fully charged, a preset tone will play and the charging light will change from red to green.

5. If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch into its "maintenance charge" mode which will last approximately 24 hours.

6. Charging times vary by temperature (10°C (50°F) - 40°C (104°F)) and condition of the battery.

7. After charging, remove the battery cartridge from the charger and unplug the charger from the power source.

• The battery charger is for charging the Hougen-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 one which has

been left in a location exposed to direct sunlight for a long time, the charging

light may ash in red color. If this occurs, charging will begin after the battery

cartridge is cooled by the cooling fan that is in the charger.

• If the charging light ashes alternately in green and red color, charging is

not possible. The terminals on the charger of battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.

CHANGING TONE/MELODY OF CHARGER

1. When inserting the battery cartridge onto the charger, it will play the last preset tone/melody that was selected.

2. Remove and reinsert the cartridge with in 5 seconds to change the tone.

3. When the desired tone/melody comes out, leave the cartridge inserted.

4. Preset tone/melody remains stored even when the charge is unplugged.

COOLING SYSTEM

• This charger is equipped with a built-in cooling fan for faster charging without damaging the battery.

• A yellow warning light will ash in the following cases: Trouble with fan and incomplete cool down of battery, or vents

2. Replace the carbon brushes with new ones.

3. Put caps back on.

1/4 “

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.
