Fit the wrench provided onto the lock nut and tap the
handle lightly with a hammer to loosen the lock nut. Take
off the die holder and use a wrench to remove the screw.
Then remove the punch.
To install the punch, insert it into the punch holder with its

OPERATION

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 (32.8
feet) of mild steel or stainless steel to be cut. Light oil or
kerosene should be used to keep an aluminum lubricated
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 (1-5/8") diameter or more in the material.
Cutting stainless steel

004792
There is more vibration when cutting stainless steel than
mild steel. Less vibration and better cutting is possible by
adding another washer (standard equipment) beneath
the die.
