OPERATION MANUAL
4.3 PRESSING PROCESS
1. Place the workpiece on the bed. It must be
completely stable and supported by packing
or shims where required. Steel pressing plates
are supplied, (Fig.4.2) which locate on the
bed in either flat or vertical position. Place the
workpiece on a combination of these to give
it stability.
NOTE:
Any packing pieces or shims used MUST
be capable of withstanding the pressure that will
be brought to bear, and MUST be of sufficient
size with sufficient surface area, so as to avoid the
possibility of slipping or springing out. Mating
surfaces MUST be horizontal so that the force
being exerted will NOT be at an angle.
2. Close the release valve by turning it clockwise
until tightly closed. (Fig. 4.3)
3. Pump the handle to bring the ram very lightly
into contact with the workpiece.
4. Position the workpiece or slide the ram to
one side so that the desired point of contact
is directly beneath the centre of the ram

5. When satisfied that the workpiece is correctly aligned and is completely stable in that
position, slowly pump the handle so that the ram begins to exert pressure on the work
piece. Continue to pump the handle whilst standing to the side. Do NOT stand directly
in front of the work, and constantly monitor the process, ensuring the ram and work
remain completely in line and there is no risk of slipping.
6. When the process is complete, turn the release valve anticlockwise in small increments to
release ram pressure and allow removal of the workpiece.
Do not exceed the rated capacity of the press. Do not allow any
person who is inexperienced in the use of hydraulic presses, to use the press unless they are
under direct supervision
