Maintenance
Hydraulics
High pressures in the hydraulic system
The hydraulic system is under high pressure. Regularly check all
pipes, hoses and bolted connections for leaks and externally visible
damage. Only use suitable tools when looking for leaks. Eliminate da-
mage immediately. Escaping fluid may result in injuries and fires.
Seek medical attention immediately if injuries occur.
Clean hydraulic system
Close or disconnect the hydraulic coupling with great care. Remove
any dirt or air which has entered the hydraulic system. The hydraulic
system can be seriously damaged. Material damage and injuries to
personnel may be caused.
Hydraulic lines
Replace any worn, cut, chafed, pinched or other damaged hydraulic
lines as well as worn tubes immediately. Broken or defective tubes
can cause the implement to move unexpectedly and uncontrollably
and may cause serious injury to personnel or damage to the imple-
ment. There is otherwise the risk of serious or fatal injury.
Be careful when welding
Do not perform any welding work in the vicinity of the hydraulic tubes.
Hydraulic oil can burst into flames very easily.
Hydraulic system at zero pressure
Work must only be performed on the hydraulic system if the tractor
and implement hydraulic system is at zero pressure. A pressurised hy-
draulic system can trigger unforeseen movements on the implement
and can cause serious damage and injuries. There is otherwise the
risk of serious or fatal injury.
Hydraulic tubes
Hydraulic tubes can age without this being externally visible. Replace
hydraulic tubes every six years. Check the hydraulic tubes on a regu-
lar basis.
