Avoid any extreme settings.
CAUTION
Incorrectly adjusted wheelbase
Risk of falling or tipping of the user
► Please note that with the rear wheel in the front position and with an unfavourable body position, the user may

► Use an anti-tipper for inexperienced users and with extreme settings of the rear wheel.

the wheelchair.
