Read, understand and follow all safety instructions and 

operating procedures. If you do not understand the  

instructions or if conditions are not correct for proper  

operation, do not operate the machine. Consult your  

supervisor or other responsible person. 

*Check that the trigger switch is not locked on.

*Check that the manual return valve is closed.

*Make sure that the proper punch and die are installed 

correctly. See 

Die Selection

 and 

Proper Punches and

 

Dies 

on next page.

*If you are using the hole locator gauge, adjust it to the  

proper distance. See 

Hole Locator Gauge Adjustment

  

on next page.

*Plug the power cord into the proper power supply.

OPERATING PROCEDURES

 

*Position the puncher at the proper location on the 

workpiece using the hole locator gauge or by locating the 

point on the end of the punch into a center punch mark on 

the piece.

With everything in proper order, the switch can be activated 

to start the electric motor. The punch piston will move out 

and push the punch through the material. Keep the switch 

on until the punch has reached the end of its stroke and 

stops. Release the switch. The automatic return valve will 

open at the end of the stroke allowing the punch piston to 

retract to its home position. The punch piston must return 

completely before another hole can be punched. 

If the punch stops in the midst of its stroke or does not 

come out of the material, open the manual return valve. 

Once the punch piston has returned to its home position, 

tighten the manual return valve.

Although the foot switch is guarded against inadvertent 

operation, it is best to position the foot pedal away from 

normal standing position. Place it in a position that 

requires deliberate effort to reach and activate the switch.

The trigger switch should be locked on only when ready 

to punch. Release the trigger switch immediately after 

punching to prevent operation by inadvertent actuation 

of the foot switch.

INSTRUCTIONS -- FOOT SWITCH

WARNING! Failure to check punch retaining nut periodically during use, can result in  

personal injury or damage to the unit could occur.
