8. When the pressure is set, hold the knob in position and lightly tighten the lock nut to hold the
knob and prevent inadvertent pressure changes.
Main Cylinder Direction Control Valve
The selector valve and the main direction control
valves are located on the top cover of the hydraulic
unit.
The Selector valve is a 2-position switching valve. It is
used to direct and oil flow to either the main cylinder
directional valve, or to the side cylinder directional
valve.
Push the Selector valve lever inward to the Main Ram
position to direct oil flow to the main directional valve.
The Main Directional valve is a 3-position spring return
to center valve:
•
Middle position: When the lever has not been
operated, the valve will always return to this
position. There is no movement of the piston.
•
Up position: When the lever is pushed inwards, the
piston of the cylinder will raise. As long as the valve
is operated, the piston will move until it is fully
retracted. When the lever is released, the piston will
stop and stay in this position. The lever will return
to the middle position.
•
Down position: When the lever is pulled outwards,
the piston of the cylinder will extend. As long as the
valve is operated, the piston will move. When the
lever is released, the piston will stop and stay in
this position. The lever will return to the middle
position.
Pressure Gauge
The pressure gauge is located on the top cover of the hydraulic unit. The gauge gives the
pressure in mPa and PSI. The maximum pressure for this press is
4350psi. (30mPa).
If this maximum pressure is reached, also the maximum capacity of the press is reached.
