Coupling and uncoupling the hydraulic connections
WARNING
Risk of injury due to pressure!
A fine jet of hydraulic oil under high pressure can penetrate through the
skin. This can cause serious injury.
► Seek medical attention immediately if hydraulic oil penetrates the
skin or eyes.
► Only open hydraulic systems after the pressure in them has been re-
leased.
► Wear protective gloves and safety glasses.
NOTICE
Soiled hydraulic connections can cause dirt to penetrate into the hy-
draulic system and cause damage!
► Clean hydraulic connections before connecting or disconnecting.
► Seal unused hydraulic connections with protective caps.
► Replace missing protective caps.
Environment
Hydraulic oil is harmful to the environment!
When coupling and uncoupling the hydraulic connections, hydraulic oil
may leak.
► Avoid releasing it into the environment.
► When coupling and uncoupling, hold the tank under the hydraulic
connections to catch any leaking hydraulic oil.
► Dispose of leaked hydraulic oil in an environmentally friendly man-
ner.
