Safety precautions:
•
Take care that the tyres always show correct air pressure. Low tyre pressure is not
only a needless obstruction for easy wheeling, it above all reduces the parking
brakes’ functional performance considerably and their operation function may
even be eliminated completely.
•
Always take care that the brakes have to operate reliably. Especially when
wheeling on slopes, it must be ensured at any time that the wheelchair will stand
still when the brakes are locked.
•
Keep in mind that on rainy and wet days and as the chair is dirty, the braking
operation is considerably changed and reduced.
•
After each adjustment of the wheel positions as well as after each tyre-change,
the brakes must be adjusted anew. Have the knee lever brakes adjusted by a
qualified medical service centre.
Advice for your orthopaedic mechanic engineer:
For adjusting the brake as the tyres are properly inflated, both filister head screws
(A+B), fixing the brake on the brake support, must be loosened (max. air pressure on
the outer tyre).
The brake must be adjusted in such a way that with a released brake on 1“-tyres a
distance (s) of ca. 15-18mm between brake dowel and tyre surface exists and a
distance of ca. 12-15mm on 1 3/8“-tyres. Re-fix the brake in this position with the filister
head screws.
Now do a test on it: the brakes should block the wheel thus far that the occupied chair
can no longer be wheeled. The wheelchair will instead skid across the floor with
blocked wheels.
