DIM012EN - 03.06.2020
For all work in connection with operating materials, the information in
the data sheets of the respective manufacturers and the information
in the document Notes on Operating Materials must be observed.
Only filters with retained particle sizes described in the fluid plans
must be used.
Depressurize the hydraulic system by opening the accumulator drain
valve, turn off the machine and prevent it from restarting.
Use personal protective equipment, e.g., suitable safety groves and
safety goggles, when working in tanks with hydraulic fluids.
Contaminated or degraded hydraulic fluids are hazardous waste and
must be disposed of according to regulations. Also clean the
hydraulic fluid tank before filling in new hydraulic fluid. When
changing the type of hydraulic fluid, the unit must be flushed with new
fluid.
Do not use cotton waste for cleaning.
When cleaning with cotton waste, fibers or thread can get loose
causing safety problems.
The following tools are required:
- A pump with pre-filter is required for changing the hydraulic fluid. - Filter
fineness 3 µm (β200)
- Hydraulic fluid, specification and quantity as specified in the technical data
- Empty oil drum or similar for collecting the used oil
- Cleaning rags. - Do not use cotton waste
- Personal protective equipment
During maintenance of the entire hydraulic system, first perform a visual inspection
of all hydraulic components for leakage and their visual condition. The following
components must be examined during maintenance of the hydraulic system:
- Hydraulic fluid filter (replace the filter cartridge of the hydraulic fluid filter, if
necessary )
- Hydraulic pump
- Pressure gauges
- Pressure relief valves and directional control valves
- Safety valves
- Fluid lines
- Check oil level in the sight glass of the hydraulic fluid tank
1. Check all hydraulic blocks, distributors, valves, and pumps for leaks and
function.
2. Check hydraulic system pressure and related sensors (sensor system).
