ence between the maximum and the comfortable reach
limits, a subjective but important consideration in design.

Position wheelchair as close as possible to the desired
object. Point front casters forward to create the longest
possible wheelbase. Reach back only as far as your arm
will extend without changing your sitting position.
Tilting
WARNING
DO NOT tilt the wheelchair without assistance.
When tilting the wheelchair, an assistant should grasp
the back of the wheelchair on a non-removable (non-
detachable) part. Inform the wheelchair occupant be-
fore tilting the wheelchair and remind him/her to lean
back. Be sure the occupant’s feet and hands are clear of
all wheels.
REACHING, LEANING - BACKWARDS.
WARNING
DO NOT lean over the top of the back uphol-
stery. This will change your center of gravity and
may cause you to tip over.
