9. Use and operation
9.1 Trailer operation
9.1.1 Setting up the trailer coupling on the towing vehicle
Move the towing device of the towing vehicle to the correct height.
Position the trailer coupling (
A ) on the towing vehicle so that the tank
trailer is horizontal when it is hitched
and so that, when the trailer is attached, there is sufficient space
between the drive shaft and the drawbar (
A1 ), especially during tight
turns.

Ball head coupling
The ball head coupling must only be coupled with an approved coupling ball (ball diameter 80 mm) that is suitable for
ensuring safe attachment and locking.
9.1.2 Coupling the trailer
1. Move the towing device of the towing vehicle or the drawbar eye of the trailer to the correct height.
2. Open the towing device on the towing vehicle.
3. Move the towing vehicle backwards until the drawbar eye engages in the towing device.
4. Secure the towing vehicle against rolling away (parking brake) and turn off the engine.
5. Check whether the towing device is engaged.
6. Establish the electrical connections and connect the service brake.

Hydraulic connections
- Connect all hydraulic lines to the towing vehicle in pairs (double action).
- For labelling to identify connection points, see the stickers on the vehicle and on the couplings.
Attaching the drive shaft
Attach the drive shaft between the tractor and the vacuum
tanker.
Ensure that the swivel head audibly engages in the PTO stub.
Fig. 33
:
Attaching the drive shaft
Before assembly, check the minimum length of the drive shaft. The minimum length is the smallest
possible distance between the tractor PTO and the connection point on the trailer. An excessively long
drive shaft can buckle during operation or even break off.
You must also read the drive shaft
operating manual carefully and follow the contained instructions.
9.1.3 Conducting a trial run
After the machine is set up and prepared and before work begins, a trial run must be conducted in unloaded condition .
