6.17 Hydraulic system
Warning! The hydraulic system is under high pressure. Hot hydraulic fluid may emit
from leaks and can cause severe injuries!
Work on pressure reservoirs of the machine may only be performed by trained
personnel. When working on the pressure reservoirs, the machine must first be rendered
completely pressureless. The pressure reservoirs may in no case be damaged or
opened because the constant preloading pressure may severely injure people. The
preloading pressure of the pressure reservoirs is present even when the remaining
components of the hydraulic system are already pressureless. During all work on the
hydraulic system, ensure extreme cleanliness. If dirt – even only in minute quantities –
enters the hydraulic system, this may lead to heavy damage to the complete hydraulic
system.
Regularly check the hoses of the hydraulic system!
Immediately replace damaged or aged hoses. Use only original hoses from ROPA
or hoses fully complying with the specifications of the original hoses! Observe the
regionally applicable safety regulations regarding the service life of hydraulic hoses.
The hydraulic system is operational after the diesel engine has been started. To reduce
wear of the hydraulic system, the engine speed during the first minutes (about 5
minutes) after a cold start should in no case exceed the value of 1300 rpm. Even
higher speeds for short times should be avoided. If your euro-Maus4 is fitted with an
independent heating system, then use it for preheating the hydraulic fluid
When first starting of the machine drive for work in environmental temperatures lower
than +10°C, proceed as follows:
Before switching on the machine drive, switch off the drives of the recleaner and pickup.
For this purpose, press the keys (9) (8) and (7) on the right joystick one after the other.
These drives are then displayed in white on the color terminal. Switch on the machine
drive by briefly pressing key (6) on the right joystick. The hydraulic system is operating,
the rollers are standing still. Wait for two to three minutes, before you switch on the
drives again, one at a time, one after the other.
