Raise the front safety guard (
65
) and place the work to be pressed on
the lower bolster pressing face (
5
) covering the piston (
4
). Ensure that
the work is positioned centrally and lower the safety guard. Screw
down the top bolster pressing face (
23
) attached to the lead screw
(
21
), by turning the lead screw handle (
20
) clockwise.
Important:
Ensure that all the components of the work to be pressed
(usually a die set) have been squeezed tightly together
before starting to pump a pressure. However, leave a 1mm
gap between the top of the die set and the top bolster (
23
)
pressing surface to allow for some initial travel of the
pressing piston (
4
) on the press.
Rotate the pressure release handle (
30
) clockwise until it has tightened
firmly. This closes the pumping system so that it is ready for you to
build up the pressure with the pump handle grip (
33
).
Warning:
Ensure that the safety guard is lowered before pumping.
Now start to pump the press by pulling and pushing gently, but
smoothly, on the pump handle grip (
33
). (The correct leverage and
force is applied by holding at the rubber handle.) It will take a few
strokes to build up pressure in the oil, but once resistance is offered by
the work to the raising of the piston, the load will be indicated on the
load gauge (
31
). Keep on pumping until the required load is achieved.
There is a maximum piston (
4
) travel of 25 mm. There is a red ring
around the piston (
4
) showing when the limit is reached (See Fig 6.)
DO NOT CONTINUE PUMPING WHEN THIS RED RING SHOWS.
If you do not stop pumping, you will cause damage to the press
mechanism.
There is an internal spring stud (
16
) within the piston (
4
) assembly that
is designed to break, protecting the press if the allowed piston travel is
exceeded. This spring stud (
16
) allows the action of the piston spring
(
19
) to pull the piston (
4
) back down when the oil pressure in the
system is released. If the stud (
16
) breaks, the spring (
19
) is not
compressed when the piston (
4
) is pumped, consequently the piston
will not return easily to the start position once the pressure is released.
