7.2 Cleaning and Disinfection
The wheelchair should be cleaned regularly according to how often it is used and how dirty it is.
Clean the frame, plastic parts and wheels with a mild cleaning agent. After cleaning, dry all parts with a dry cloth.
Clean cushions and upholstery with warm water and washing-up liquid. Remove stains with a sponge or a soft
brush. Rinse afterwards with clean water and allow the parts to dry before mounting and using.
To disinfect, use water-based agents and follow the manufacturer’s instructions.
7.3 Changing a Tire
If a tire is punctured, the user or a helper may be able to change it without assistance. The procedure requires
having strong hands, practical ability and suitable tools. It is advisable to have a puncture repair kit and an air
pump for emergencies (excluding situations with-proof tires). Suitable air pumps, puncture repair kits or punc
-
ture sprays that fill the tire with expanding foam can be purchased at most bicycle shops.
Removing tires and tubes
•
Gently pull the tire edge over the edge of the rim with a tire lever (or two, if it is sitting very tightly).
Take care not to damage the rim or the tube (Image 14).
•
Screw off the valve nut and pull the valve out from the rim and the rim strap.
•
Pull out the tube from between the tire and the rim (Image 15).
Repair and check-ups
•
Repair the tube according to the instructions in the repair kit or replace it with a new tube.
•
Before remounting the tire and tube, make sure that no foreign objects that may have caused the puncture
are caught in the rim or tire.
•
Ensure that the tire band is intact. It protects the tube against damage from the spokes.
•
Push the tube into place between the tire and the rim.
Mounting tires
•
Gently pull the clear tire edge over the edge of the rim. Starting with the valve.
•
Check that there are no twists at all in the tube, otherwise air can get out.
•
Work the whole way around until the last section of the tire edge is taut and can be edged into place with
one or two levers.
The wheelchair must not be used in salt water.
Avoid getting salt, sand and other dirt that can
cause damage in the wheel bearings, caster
mounting bracket or rear wheels. If this hap
-
pens, the bearings should be replaced.
NOTICE
Do not wet-wash. Do not use high-pressure
equipment or a water jet. The wheelchair com-
ponents must not be put in a washing machine.
NOTICE
Do not use corrosive cleaning agents, solvents or
hard brushes.
NOTICE
Clean the seat and back upholstery, cushions,
handles and armrest before disinfecting.
NOTICE
Pumping
•
Check on both sides that the tube is not caught between the tire edge and rim.
•
Push the valve lightly in and pull It out again to make sure that it is not caught on the tire edge.
•
Fill the tire with air to the point where it is still possibnle to press It in with a thumb. If the control lines on
both sides of the tire indicate the same distance to the rim edge, the tire is centred. If the tire is not centred,
let some air out and adjust the tire until it is centred. Now pump up the tire to its maximum working pres
-
sure (see the side of tire) or at least 3.5 bars (350 kPa). Then screw the dust cap on, tightly.
Ensure that the tires have the correct pressure before using the chair.The maximum air pressure limit is
marked on the side of the tire. It must always be on a minimum of 3.5 bars (350 kPa) on the rear wheels.Like
push wheel locks, the knee-lever wheel locks are only effective when the air pressure is sufficiently high and
when they are correctly positioned.(When locked, the brake pad should push the tire in 5mm (allowing for
technical alterations).
