A hydraulic press is a device using a hydraulic cylinder to generate a compressive force. Hydraulic presses are commonly used for forging, clinching, moulding, blanking, punching, deep drawing, and metal forming operations.
== Safety ==
*This machine is intended to operated by one person
*Wear proper eye protection
*Establish solid footing before operation
*Keep hands away from press points of operation
*Keep fingers out of pin holes
*Guard the work piece to prevent projectiles from reaching operator
*All pins must be fully inserted before applying pressure
*Never exceed the recommended stroke of 5 inches for this press. Exceeding the stroke will cause damage to the inner packing.
==Inspection==
Check for physical damage such as bent components, or leaking oil.
If Leaking oil is noticed refer to the Troubleshooting guide.
==Press Operations==
===Basics===
*Remove the table pins from the table and raise or lower the table with the crank to the desired height.
*Insert the table pins back into the table fully and unwind the crank to remove the tension off of the cables.
*Use the needed cross members if the part is too small to fit the table.
*Make sure the release valve hand wheel is closed so that the pump holds pressure.
*Center the part under the screw nose.
*Slowly pump the handle with an up and down motion.
*Once initial contact between the part and the screw head happens make sure the part is centered under the head before continuing.
*Slowly in a consistent movement pump the handle.
 *If the part starts to bend, or lean to one side stop immediately and release the pressure.
*If you are pressing out a part you will have to catch the falling part from under the table.
*Once the part is pressed out or the part is pressed in, slowly release the pressure and allow the head to raise back to the top position.
===End of Work===
If no other parts are needing pressed 
*Leave the release valve open so the head stays at the upper level.
*Clean the area around the press, it should be as clean as you found it.

*Smoothing application of pressure.
*Centering the part in the press.
*Securing any non moving parts or fixtures with clamps.
