Punching metal sheets
Gather together the appropriate tool set comprising a punch, punching die and tension bolt. For best punching
results we recommend using high-quality ALFRA-tools.
Be sure to punch only one metal sheet at a time. Two or more layers of material may not be
processed during one punching process.
1. Mark the exact hole position for the punching.
2. Now use a spiral or step drill to make the starting hole in the metal sheet.
3. Turn the drain screw as far as it will go to the left into the OFF position. The load piston moves to its starting
position.
4. Screw the tension bolt into the load piston by hand until it stops.
Always ensure that the entire length of the thread is used otherwise the tension bolt may pull out.
5. Place the spacer and punching die on the tension bolt. Then guide the tension bolt through the
prepared hole.
6. Turn the punch onto the tension bolt from behind and align the punching die with the markers.
7. Move the punch into position and screw on the punch by hand in order to fix the complete assembly in place.
Always ensure that the entire thread of the punch is used.
8. Turn the drain screw to the right into the ON position to build up the pressure. Pump on the hand lever until the
hole is punched. Avoid the punch tips touching the die bottom.
Risk of injury. Keep hands and fingers away from the punching die and punch whilst punching.
9. Pump 3 to 4 times with the hand lever to press the punching scraps loosely into the punching die.
10. To release the pressure turn the drain screw into the OFF position. Let the load piston return to its starting
position.
11. Unscrew the punch and thoroughly remove all scraps of material from the punching die.
Cleaning and care
Regular cleaning and caring can increase the leakproofness of your ALFRA hydraulic punch driver and extend its
lifetime. Please proceed as follows:

Regularly remove dirt and abrasive dusts from the sliding surfaces and moving parts.

When the punch driver is no longer used, turn the drain screw into the OFF position and release the pressure.

Store and use the punch driver in a dry place.
