NOTE:
• When installing the screw and lock nut, be sure to tighten securely. If they
become loose during operation, the tool may break down.
Pre-lubrication
Coat the cutting line with machine oil to increase the punch and die service
life. This is particularly important when cutting aluminum.
Cutting method
004787
Smooth cutting is achieved by holding the tool upright and applying gentle
pressure in the cutting direction.
Apply tool oil to the punch about every 10 meters of mild steel or stainless
steel to be cut. Light oil or kerosene should be used to keep an aluminum lubri-
cated continuously. Failure to lubricate aluminum in the cut will cause chips to
adhere to the tool, dulling the die and punch and increasing load on the motor.
Cutouts
004789
Cutouts can be done by first opening a round hole of about 42 mm diameter or
more in the material.
