build-up speed dependent on the angle of rotation.
To open the clamps press the control lever to the right. The moving speed
dependent on the angle of rotation.
Pressure adjusting valve for milling pressure, beat forming pressure, heating
pressure and cooling pressure. The manometer provides information on the
regulated pressure.
Pressure relief valve. Anti-clockwise turn can lowered the pressure. The lowering
speed dependent from the number of turns. Right turn pressure hold.
