by a specialist dealer.
Clean the front wheels

2. Remove any dirt or hair from the front wheel bearings.
Check the bolts
Bolts can work loose through constant use.
1. Check that the bolts are tight (on the footrest, seat cover, sides,
backrest, frame, seat module).
2. Tighten any loose bolts with the suitable torque. Therefore
refer to the Service Manual, available on the internet at
www.kueschall.com.

of repeated loosening and tightening.

brake is set correctly if the brake shoe depresses the tire by a
few millimeters when the brake is applied.

correctly set by a specialist dealer.
IMPORTANT!
The parking brakes must be reset after replacing the rear
wheels or changing their position.
Checking after a heavy collision or blow
IMPORTANT!
The wheelchair can sustain visibly undetectable damage
as a result of a heavy collision or hard blow.
– It is essential to have your wheelchair checked by a
specialist dealer after a heavy collision or hard blow.
Repairing or changing an inner tube
1. Remove the rear wheel and release any air from the inner tube.
2. Lift one tire wall away from the rim using a bicycle tire lever. Do
not use sharp objects such as a screwdriver which could damage
the inner tube.
3. Pull the inner tube out of the tire.
4. Repair the inner tube using a bicycle repair kit or, if necessary,
replace the tube.
5. Inflate the tube slightly until it becomes round.
6. Insert the valve into the valve hole on the rim and place the tube
inside the tire (the tube should lie right round the tire with no
creases).
