NOTICE
Before connecting or removing hydraulic lines from the attachment, ensure
that the operating hydraulics is not under pressure!
Information!
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 that are to
be opened before starting setup or repair work, for example fitting/removing an
attachment!
Releasing pressure
Release the pressure as follows:
☞
Park the machine on firm and level ground.
☞
Lower the attachment completely to the ground.
☞
Stop the engine.
☞
Turn the starting 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!
