Lift

When the pump motor starts, the oil flows through the non-return valve to the lift cylinders.

Lowering

When the lowering valve is actuated by the lowering button on the tiller arm, the valve opens to allow the oil in the pressure lines to return to the oil tank. Lowering using the button on the tiller arm gives a constant lower speed.

Operating pressure

The operating pressure at rated load is 171 bar.

Relief valve

The relief valve opens at 180bar.

Pressure sensor

The pressure sensor is used to regulate the drive speed and is influenced by the load and the drive direction. It has an analog operation.
