What to do if the lift supports no longer want to retract and thus prevent further travel:
The lift supports have an emergency operation that can be carried out in the event of control failure, hydraulic failure and interruption of the power supply to one or more units.
Aids: Jack, jack stands, wooden blocks, hexagonal spanner AF10
- Raise the vehicle with the jack and secure it additionally with the jack stands
- Loosen the emergency release screw with a hexagonal spanner by 2.5 turns (see picture)
- Raise the jack slightly, relieve the load on the jack stands and pull them out.
- Lower the jack slowly - the support retracts automatically due to the vehicle weight
- Raise the vehicle again with a jack
- Support with wooden blocks
- Lower the jack - The prop now retracts to the maximum level
- Raise the vehicle with a jack and remove the wooden blocks underneath
- Lower the jack - The vehicle now stands securely on all tyres again, the support is only slightly extended
- Position the jack under the support and slowly push it in as far as it will go
- Tighten the emergency release screw hand-tight.
IMPORTANT: Immediately thereafter, visit a specialist workshop and have the emergency drain plug tightened with a tightening torque of 5Nm.
