WARNING
Check hoses and couplings
Check all hydraulic hoses for damage before connecting them.
Check all hydraulic couplings for firm seating after connecting
them. Defective hydraulic hoses and poorly fitting hydraulic
connections can trigger unanticipated movements in the machine,
causing severe damage to the machine as well as personal injury.
Serious or fatal injury may be caused as a result.
Secure the tractor's control devices
In the transport position, secure the control devices on the tractor
against unintended actuation and lock them if possible. Uninten-
tional activation of a control device can trigger unpredictable
movements of the machine and cause serious machine damage
and personal injury. Serious or fatal injury may be caused as a
result.
Check the routing of the hydraulic hoses
Close or disconnect the quick couplings with great care. Remove
any dirt or air which has entered the hydraulic system. The
hydraulic system may otherwise be seriously damaged. Material
damage or personal injury may be caused as a result.
Hydraulic connection at zero pressure only
Only connect hydraulic hoses to the tractor hydraulic system if the
tractor and machine hydraulic system is at zero pressure. A
hydraulic system which is under pressure can cause unforeseen
movements on the machine.
Avoid mixing oils
If the machine is used on different tractors, an impermissible
mixing of oil may occur. Impermissible oil mixtures can destroy
tractor components.
High pressures in the hydraulic system
The hydraulic system is under high pressure. Regularly check all
lines, hoses, and screwed connections for leaks and externally
visible damage. Do not use hands to search for suspected leaks.
Only use suitable equipment when looking for leaks. Rectify any
damage immediately. Fluid escaping under pressure can
penetrate skin may result in injuries and fires. Seek medical
attention immediately if injuries occur.
