Translation of the Original Operating Manual
2.4.3 Hydraulic system
The hydraulic system is under high pressure.
Verify that the hydraulic hose lines are connected properly.
Do not block any actuators on the machine which are used to perform direct hydraulic movements
of components, e.g. tipping, swinging and sliding.
The respective movement must stop automatically once you release the corresponding actuator.
This does not apply to the movements of devices:
o that are continuous,
o that are controlled automatically,
o that require a float position or pressurized position for operation.
Before working on the hydraulic system:
o Secure raised moving parts of the machine from being lowered inadvertently.
o Depressurize the hydraulic system.
Have an expert verify the proper technical condition of the hydraulic hose lines at least once per
year.
Replace hydraulic hose lines when detecting obvious defects, damage and wear. Use only original
hydraulic hose lines.
Do not use hydraulic hose lines for more than six years, including any storage time, which must not
exceed a period of two years.
Even if stored properly and only subjected to the permissible stress, hoses and hose connections
are subject to natural aging, limiting their storage time and period of use. The actual period of use
may deviate from these specifications based on experience and, in particular, taking potential
hazards into consideration. The same guidelines apply to hoses and hose lines made of
thermoplastics.
Never attempt to seal leaking hydraulic hose lines using your hand or fingers.
Fluids (hydraulic oil) escaping under high pressure may penetrate the skin and enter the body,
resulting in severe injury.
Seek immediate medical attention if injury from hydraulic oil has occurred. Risk of infection.
2.4.4 Electrical system
Switch off the power supply before performing any work on the electrical system. Turn the main
switch to the “OFF” position and secure it against restart.
Use only the designated fuses. Using higher amperage fuses may destroy the electrical system –
as there is a risk of fire.
Make sure all electrical installations are completed by trained and qualified personnel and as
specified in the circuit diagram.
