12 Maintenance and Cleaning
It is important that you follow the following cleaning and
maintenance schedule in order to keep your wheelchair in
tip top condition.
12.1 Tyre maintenance and pressures
If pneumatic tyres are fitted to your wheelchair it is important to
regularly check the air pressure and for signs of wear.
The correct pressures are between the minimum of 137 kiloPascals
(20 psi, 1.37 bar) and the maximum 241 kiloPascals (35 psi, 2.41 bar)
for rear and front wheels (see side of tyre).
The pressure will need to vary, depending on the weight of the user.
IT IS IMPORTANT that front wheels are inflated to the same pressure
as a pair, and likewise the rear. The inflator pump provides the safest
method of inflating your wheelchair tyres and the pressure can be
checked with a standard motor vehicle pressure gauge.
Do not inflate beyond the maximum allowed tyre pressure.
12.2
Tyre wear
When inspecting the tyres for signs of wear, look for significant scuff
marks, cuts and a diminished tyre tread. Tyres will need to be changed
when the tread cannot be seen over the complete surface of the tyre.
12.3
Drive wheel tyre repair
•
Remove the plastic hub cap by levering it off (Fig.
•
To remove the wheel, use a 5.0mm hex
key on the 4-button head studs. The
button head studs protrude through
to the back of the wheel. Undo the
corresponding nyloc nuts using a
13mm spanner
(Fig.
102).
•
Remove the wheel. Note that when
replacing the wheel use new nyloc
nuts.
•
There are 5 rim studs that must be
loosened/tightened in the number
order shown. Use a 6mm Allen key to
release the studs.
(Fig. 103)
•
Lift the inner rim off the tyre wall (Fig.
104).
•
Lift the tyre and tube off the outer rim.
Gently get hold of the inner tube just
behind the valve.
•
Carefully feed the tube out of the tyre.
To refit
•
Place the tube inside the tyre & rest it
on the outer rim with the valve stem
aligned with the cut out in the rim.
Face the valve stem outward.
•
Place the inner rim over the tyre, tube
& outer rim. Align the cut out to fit
over the valve stem & match it up to
the cut out in the outer rim. Make sure the stud mounts are in line
on both rims.
•
Tighten the studs in the sequence shown earlier taking care not to
pinch the tube.
•
Slowly inflate to the pressure marked on the tyre. Refit the wheel
back onto the motor shaft and fix it safely with the 4-button head
studs to a torque of 47Nm.
In case a solid tyre is used the wheel needs to be replaced as a complete
assembly.
12.4 Removing the castor wheel
•
Note which one of the two holes is used to mount the castor
wheel. Ensure that both castors use the same mount position.
•
Depending on the castor wheel type use two 5 mm hex keys or

•
The SALSA tyre can be removed and repaired/exchanged by following
the rim split procedure for the drive wheel.
12.5 Cleaning your wheelchair
The wheelchair should be wiped over once per week with a slightly
damp, not wet, cloth and any fluff or dust that has accumulated around
the motors should be blown or dusted away.
Make sure that you dry all parts of your wheelchair if it becomes wet
or damp after cleaning or if it is used in a wet or damp atmosphere.
It is important that should the wheelchair be used by more than one
person it is cleaned thoroughly to ensure there is no cross infection.
12.6
Tears, dents, wearing or slackening of upholstery particularly near
to metal could result in poor posture or lower levels of comfort and
pressure relief.

You can wash all parts of the covers with a gentle-wash detergent at
40°C. You can spin-dry the covers, but do not dry them in a dryer. You
can remove all parts of the covers independently of each other and
wash them separately. Take out the foam inlays prior to washing and
close the Velcro fasteners!
Where upholstery cannot be removed, clean regularly to prevent build

12.8
Clean the control system and the joystick with a cloth dampened with
diluted detergent. Be careful when cleaning the joystick.
Never use abrasive or spirit based cleaners
Speciality controls
Ensure that wafer boards, joysticks (all variants), head arrays and
switches (all variants) are cleaned with a mild disinfectant and a
cleaning cloth to avoid any cross infection possibilities. Following
removal from chair regularly wash the sip & puff mouth piece and
tube to maintain cleanliness and functionality.
WARNING - Ensure control is switched off before cleaning.
12.9 Lighting bulb exchange procedure
If bulbs of your lights and indicator system show a defect, please
proceed in the following way:
Front lights and indicators (TUV light type):
two 13 mm spanners to undo the axle bolt.
Remove the nyloc nut in case of the hex bolt type. Always use a
new nyloc nut when refitting.
There is an enclosed spacer between the wheel bearings. When
refitting do not try to force the bolt through. Gently move the
wheel back and forth until the bolt slips through.
Withdraw the axle bolt. Remove the castor wheel.
