▶ Wear cut-resistant gloves.
▶ Use pliers to remove the punched-out plug.
4.1. PREPARING FOR THE PUNCHING OPERATION
1. Determine the size of hole to be punched.
2. Drill a guide hole in the material to be punched.
▶ Guide hole diameter for draw bolts [} Page 6]
▶ Guide hole drilled.
4.2. INSERTING THE DRAW BOLT AND PUNCH
1. Screw the appropriate draw bolt into the hydraulic cylinder (1).
2. Guide the matrix over the draw bolt into the hydraulic cylinder (1).
▶ Insert a spacer washer between the hydraulic cylinder and matrix.
3. Feed the draw bolt through the guide hole.
4. Screw the punch on to the opposite end of the draw bolt.
▶ Align the cutting edge of the punch with the material to be punched.
5. Screw up the punch tightly by hand.
▶ The manual hydraulic drive is now ready for the punching operation.
4.3. PERFORMING THE PUNCHING OPERATION
NOTICE
Uncontrolled pump strokes
Damage to the sheet metal punch.
