IMPORTANT !
INCREASING THE SEAT HEIGHT, MOVING THE REAR WHEELS FORWARD AND INCREASING
THE BACKREST ANGLE WILL SIGNIFICANTLY DECREASE REARWARD STABILITY. IT IS
ESSENTIAL THAT A STABILITY CHECK BE PERFORMED AFTER ANY OF THESE ADJUSTMENTS
ARE MADE. STABILITY CHECKS SHOULD BE PERFORMED WITH AN ATTENDANT BEHIND THE
CHAIR AND WITH ANTI- TIPPERS PROPERLY INSTALLED AND ADJUSTED.
