■ hydraulic opening device SYK-15 type
■ size of the rod, washers, nuts will be ready.
■ Size is (top left): 114, 100/101, 89, 80, 76, 63
■ Maximum shear force: 150kn
■ Maximum stroke: 22mm
■ Packing: iron box
■ Weight: 22KG

Steps for usage:
1. To be hole in the hole before the workpiece, first with a hand drill a 11.5 mm guide hole.
2. Insert the piston rod into the screw hole of the piston cylinder, and then insert the gasket into the piston rod and then into the die, and then insert the piston rod into the guide hole of the workpiece, and finally screw into the punch so that the punch Machining surface closely, punch, workpiece, die three reliable fixed.
3.Close the oil return valve clockwise, and then press the push-in lever repeatedly to start the piston pump. The oil pressure rises, and the shear force between the die and die increases. The die cuts the hole in the workpiece until it is cut. Immediately after cutting off, press and hold the lever.
4. Unscrew the oil return valve counterclockwise to completely unload the oil pressure, and complete a complete opening procedure after the above four steps.
5. Unscrew the punch, remove the die in the mold, wipe clean mold.
■ Note: Hole can only be opened in the metal plate, the so-called 'metal plate' refers to the following 4mm iron plate, aluminum, stainless steel plate can only be within 1.2mm!
