- Storage: When not in use, store the towbar ball in a dry, protected environment to prevent corrosion and damage.
- Inspection: Before each use, visually inspect the towbar ball for any signs of wear, cracks, bends, or corrosion. Ensure the locking mechanism operates freely. If any damage is observed, do not use the towbar ball and contact Westfalia support for advice.
