4. WARNING!
Risk of accident due to unhitching of the ball coupling during transport!
If the coupling is not fully closed the compressor can become uncoupled from the towing vehi‐
cle and cause an accident.
➤
Check correct coupling.
➤ Check correct location of the security pin.
5. Place the open coupling over the towing vehicle ball hitch.
The weight on the coupling will cause it to audibly close. The coupling locks automatically.
Closing and locking is automatic.
6. Push the handle down to be certain of locking.
The coupling is fully locked when the handle is fully down and can be pushed no further.
7. Insert the security pin in the ball coupling fixing opening.
