18.3.1 Connecting trailer
Risk of injury due to non-roadworthy machine/trailer unit!
If the support, axle and trailer loads are exceeded during operation, the machine/trailer unit is
no longer roadworthy.
• When operating with the trailer, ensure that the permitted support, axle and trailer loads are
not exceeded.
Risk of injury due to unexpected movements of machine and trailer!
If there are people between the machine and trailer during the coupling process and if the
uncoupled trailer moves in an uncontrolled manner, there is a risk of injury.
• When coupling, ensure that there is nobody between the machine and trailer.
• Secure the trailer against rolling away.
Risk of injury due to insecurely locked trailer!
If the bolt (2) is not completely engaged, the trailer coupling is not locked and the trailer may
become detached from the trailer coupling and endanger people.
• After making the connection, ensure that the bolt (2) is completely engaged.
