Install the hydraulic punch with the long stem facing downward.
Before using the punch make sure that the set screw and cap nut are tightened securely.
Advance the punch through the die and check for proper alignment. The punch must pass freely through the die. Minor adjustments to the die are possible by loosening the set screw and repositioning the die, then re-tightening the set screw.
During punching operation, periodically check the cap nut to ensure that the punch remains tight. Remove slugs from the punch to prevent damage.
Dry stripping is a principal cause of hydraulic punch failure. Lubrication will facilitate easy punching and will significantly prolong the life of the punch.
