Troubleshooting
Working on the spring-loaded cylinders is dangerous and may only be performed
by persons trained to do this work and who are familiar with
working on preloaded spring assemblies.
Warning! Danger of severe injuries from parts flung away with great force. Never open
the spring-loaded cylinder. The parts inside of the spring-loaded cylinder are preloaded
with high spring force and may be flung away and injure persons if the spring-loaded
cylinders are opened incorrectly.
8.15 Readjusting the brake
Work on the vehicle brakes may only be performed by specialist personnel with
corresponding training (for instance, motor vehicle mechanics, agricultural
machinery mechanics, brake service, etc.) in compliance with the applicable
safety regulations.
The wedge brake is fitted with an automated readjusting device. Readjusting the brake is
therefore not required.
8.16 Hydraulic valves
All hydraulics valves are electrically controlled. Problems on solenoid valves may be
located using specific test cables (ROPA Art. Nr. 330197), which are supplied with each
machine. These test cables may only be connected to the solenoid valves by trained and
instructed specialist personnel.
If an electrically controlled valve should malfunction, then in any case, without exception,
call in a specialist. In no case should a try be made, by shaking the solenoid valve
concerned, to remedy possible contact problems or a possible line break. If the valve
is suddenly opened during such tries, then the person concerned may suffer deadly
injuries.
Warning! Troubleshooting and fault repairs on all components of the hydraulic system
are exclusively the task of trained specialists. We expressly warn against attempts
to repair or arbitrary tests in unauthorized manner on electromagnetically operated
hydraulic valves. If, during such tests or attempts to repair, parts of the hydraulics system
are suddenly pressurized, this may lead to unintentional machine movements. This may
jam persons or even lead to crush injuries.
