Risk of injury due to escaping hydraulic fluid!
The entire hydraulic system must be depressurized by manually
actuating the accumulator drain valve in the fluid cabinet before
starting any maintenance and repair work.
Further information can be found in chapter "Hydraulic system" of the User

Depending on service conditions, the hose lines should not remain
in use for more than four years.
The information in the data sheets of the fluid manufacturers and in
the document Notes on Operating Materials must be observed
during all work involving fuels and fluids.
The filling quantities of the fuels and fluids are stated in the
respective fluid schedules.

• Switch off the hydraulic system
• Depressurise the hydraulic system
• Empty the hydraulic tank (drain or pump off the oil)
• Clean the tank
