OPERATING PROCEDURES
1. Before make any adjustment, turn off the power supply and unplug the power cord.
2. Check the position for punching and adjust the slide stopper to the required distance. The slide stopper, which is set to
hold the hole puncher at a constant distance from the edge of the workpiece, is held in place by one or two socket head
cap screws. Loosen the cap screw(s) and tap the slide stopper into the desired position. Retighten the cap screw(s).
3. Plug the power cord into a power outlet, ensuring that the voltage of the tool is the same as the supply.
4. Check that the return lever is fully closed in the clockwise direction.
5. Make sure that the punch piston is fully retracted.
6. Make sure that the proper punch and die are selected and that they are installed correctly.
7. Place the puncher in the require position on the work piece, using the slide stopper as a guide and lining up the point
of the punch with the center mark of the hole to be punched.
8. Pull the trigger switch. The punch rod will extend and push the punch through the material. Keep the switch on until the
punch has reached the end of its stroke and returns to its starting position. If the punch doesn’t return after punching
finishes, release the switch to turn the motor off. Pull the switch again to run the motor and to return the punch.
(See further explanation below for procedure when punch becomes stuck in the material.)
To aid accurate and easy positioning of the punch, the switch can be operated on and off to jog the punch down to the
work piece. If the position is not satisfactory, open the manual return lever to retract the punch for another attempt. If the
punch doesn’t return to its starting position with manual return lever open, pull the trigger switch to return the punch.
CAUTION WHEN USING THE STRIPPER
Do not position the material with one end or both ends
unsupported by the stripper. If the material is not properly
supported, it will move when the punch tries to return causing
the punch to jam and damage the tool.
Material
Stripper
When the punch fails to come out of the material after the punching:
1. Pull the trigger switch to run the motor and to return the punch to its
starting position by hydraulic power.
2. Release the switch, when the punch is fully returned to its starting
position.
3. Proceed with the next punching operation according to the normal
operating procedure.
When the punch fails to come out of the material after the
punching or when it is necessary to stop the operation before
punching is finished:
1. Turn the return lever counterclockwise until it hits the spring pin and
then immediatley back to its starting to release the internal pressure.
Note: If at this stage the punch retracts from the material under its own
power, allow the punch to completely return and then turn the return
lever back to its position. In this case it is not necessary to complete
the stages 2 and 3.
2. Pull the trigger switch to run the motor and to return the punch to its
starting position by hydraulic power.
3. Release the switch when the punch is fully returned to its starting
position.
4. Proceed with the next punching operation according to the normal
operating procedure.
