Correct function
• Have a second person lift the wheelchair up slightly in
the rear, so that the rear wheels have approximately 1
cm ground clearance.
• Pull the anti-tipper (1) upwards. The anti-tipper must lock
immediately and completely.
• In case the anti-tipper can be pulled upwards, then the
immobilisation mechanism needs to be adjusted. Please
see chapter "Adjusting the Immobilisation
mechanism of the anti-tippers" on page 78.
• Repeat the procedure on the other side.
