UPHOLSTERY
The seat upholstery is made of two-ply polyester fabric and is attached to the seat frame by straps.
It can easily be removed by undoing the straps under the seat.
To remove the backrest upholstery, first take off the cover. Then remove the elastic strap and any
accessories, and pull the upholstery straight up.
The seat and backrest upholstery are machine-washable at 40°C.
REAR WHEEL/CASTOR FRONT FORK ATTACHMENT
Tyre/inner tube: Check the tyre pressure (see side of tyre) at least once a month; also check the tread.
Spokes:
Loose spokes can lead to wheel wobble. Consult a cycle dealer or your wheelchair
supplier if you need to adjust the spokes.
Wheel axles:
The axles should be kept free of dirt. Clean as necessary.
Ball bearings:
The ball bearings require no maintenance.
Handrims:
If a handrim should be damaged in such a way that it could lead to hand injury, it
should be replaced.
Front fork attachment: To achieve the best operating conditions, the attachments should be installed
at the correct angle. Check also that the front forks are tightened, see para 12:4.
BRAKES
The function of the brakes is dependant upon tyre pressure. Encrusted dirt can have a negative
effect on the brake mechanism. The brakes should be checked at least once a month. In the event of
adjustments see para 12:10
WASHING THE FRAME
Both for your own comfort and the longevity of the chair, it is important to keep the wheelchair clean.
Sting is easy to wash and keep clean. Wash the chair with car shampoo or washing-up liquid. If the
chair is particularly dirty, a grease remover can be used.
TOUCH-UP PAINT
Small bottles of touch-up paint, to repair scratches and chips, are available in all Sting colours.
MISCELLANEOUS
If there is a fault on your wheelchair you should contact your dealer at once. Defective chairs should
not be used. If your chair needs reconditioning or repair, only original Cross or parts of equal quality, as
specified in our diagrams, should be used. Etac will not be held responsible for damage or injury caused
by use of non-original parts.
(!) If necessary, lubricate moving parts/joints with cycle oil or similar.
