5 Using the press
5.1 First use
Before using the press for the
fi
rst time, the piston needs to be moved up and down a few times. From the mid
position, push the piston down and back up, then move it up to the maximum stroke position and back down
(avoid hitting the piston against the pilot sleeve or head cover). Repeat these movements a few times, which
will remove air from the cylinder and enable effective lubrication.
In presses equipped with a hydraulic actuator with an internal safety valve, after reaching the lower extreme
stamp position – the pressure in the hydraulic system and force on the stamp drops to a value close to zero.
5.2 Regular use
Place the workpiece on the working table so that it is directly under the piston rod. The centre of the piston
must be in alignment with the application axis. Take care when performing operations on elements that are
likely to
fl
y off, break (especially casting elements and hardened elements) or bounce up as a result of the
applied load. In this event, a cover must be installed around the workpiece, or the operator should stand at a
safe distance.
It is not permitted to use the return stroke of the piston for performing operations on a workpiece (e.g.
stretching).
Upward movement of the piston rod can be used only for adjustment of the working
table or returning the piston rod to its start position
After correct placement of the workpiece on the working table, press the start button on the control panel
and push down the direction valve lever (see label next to the lever). If the application point does not lie on
the cylinder’s axis or the contact area is not right, move the piston upwards and adjust the location of the
workpiece.
