Raising
Operation state:
• Motor is running in full speed.
• The steering wheel is actuated or not.
• The implement lifter is activated upwards.
The operator has actuated the hand lever (10) to its raising position (rear position), which
moves the slide (9) to change the hole pattern between the connections in the valve. The
hole pattern is adapted for the raising procedure. Oil forces through the non-return valve
(8), through the slide (9) and presses out the piston in hydraulic cylinder (11).
When the piston in cylinder (11) is fully extended and the hand lever still is activated, the
oil will flow only through the valve (6) and a noice will be heard from the valve.
When the hand lever is released, valve (9) will reurn to its neutral position and the system
switches over to its normal state. The piston in the hydraulic cylinder (11) is then locked in
its actual position.
