6.3.2 Controlling double-acting hydraulic devices
Double-acting hydraulic devices are controlled by
control levers.
Throwing the control lever away from the operator's
side causes the lower hydraulic connection (usually
colour-coded blue) to be supplied with hydraulic fluid.
Throwing the control lever towards the operator's side
causes the upper hydraulic connection (usually colour-
coded red) to be supplied with hydraulic fluid.
How far the control lever is thrown determines the flow
rate in the associated line
and thus the speed of motion
of the implement.

WARNING / DANGER / CAUTION!
Before the rerailing equipment concerned is removed, make sure that the load is
in a stable, immovable condition.
Procedure:
1. Return all implements to home position.
2. Switch off the hydraulic unit.
3. Move the lever on the manual pressure shut-off valve into the closed position (turn
clockwise to the stop). Also check the pressure on the attached pressure gauge. This
should be practically “0”.
4. You can now disassemble the system as described in “Connection of hydraulic devices”
and in the separate instructions for the rerailing equipment used.
REMARK:
Components should be disassembled in reverse order to assembly.
