Operation
3.56 Releasing the pressure on the operating hydraulics
Danger!
Before connecting or removing hydraulic lines from the attachment, ensure
that the work hydraulics is not under pressure.
Risk of injury.
☞
Ensure that no-one is dangerously close to the machine.
Notice!
The hydraulic system of the machine is still pressurized even when the engine is
not running. The hydraulic quick couplers can be released, however they cannot
be re-attached due to the residual pressure in the lines.
• Release the pressure in the sections of the system and hydraulic lines which are
to be opened before starting setup or repair work, for example fitting/removing
an attachment.
Releasing pressure
☞
Place the machine on level ground.
☞
Lower the attachment completely to the ground.
☞
Stop the engine.
☞
Turn the ignition key to position
1
.
☞
Move the control lever or the pedal of the hydraulic circuit in all directions repeatedly.
➥
The pressure in the system sections that have been actuated is released. This can
be seen by the brief movement the hoses make as the pressure is actually released.
➥
Uncouple the attachment immediately after the pressure has been released,
otherwise pressure can be created again.
Pressure release with proportional controls (option)
☞
Park the machine on level ground.
☞
Lower the attachment completely to the ground.
☞
Stop the engine.
☞
Turn the ignition key to position
1
.
➥
Release the load only after you have switched on ignition and waited 2 seconds
(otherwise if actuated too early, the characteristic curve is shifted and the load is not
released).
☞
Release the pressure on the auxiliary hydraulics or the 3rd control circuit by pressing
the rocker switch connected with the left or right-hand proportional joystick to the left
and right.
➥
The pressure in the system sections that have been actuated is released. This can
be seen by the brief movement the hoses make as the pressure is actually released.
➥
Uncouple the attachment immediately after the pressure has been released,
otherwise pressure can be created again.
