When replacing hydraulic hoses, proceed as follows:
Danger
Shut down the machine before starting work and secure it against
unauthorised or accidental starting.
Ensure that all pressures in the hydraulic system and in the delivery
line have fallen to 0 bar.
Hydraulic hoses may be mechanically prestressed. There is a risk of
injury from whipping hoses.
Relieve oil pressure completely.
Notes
Mark all hydraulic hoses and their corresponding connection points
for reassembly.
Environmental protection
Carefully collect escaping hydraulic fluid without fail and dispose of
in accordance with regulations! Guard against oil spillage. Biologi-
cally degradable hydraulic fluids must also be disposed of separa-
tely from other waste, just like mineral hydraulic fluids.
Comply with the relevant national and regional regulations.
Only work with waste disposal companies who are approved by
the responsible authorities.
Collect escaping hydraulic fluid in a suitable oil catch pan.
Take care when undoing the joints.
Close the connection points with a plug immediately after you
have removed the old hydraulic hoses. No dirt may enter the
hydraulic circuit and the hydraulic circuit must not be drained.
Dispose of the collected hydraulic fluid properly.
