14.0 Maintenance and Cleaning
CAUTION!
It is important that you follow the following cleaning and
maintenance schedule in order to keep your wheelchair in tip
top condition.
14.1 Tyre maintenance and pressures
14.1.1 Tyre pressure
CAUTION!
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.
NOTE: It is important that front wheels are inflated to equal
pressures 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.
DANGER!
Do not inflate beyond the maximum allowed tyre pressure.•
Always use the pump that is supplied with the chair, •
Never use a forecourt pump•
14.1.2 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.
14.1.3 Drive wheel tyre repair
Remove the plastic hub cap by levering it off (
Fig. 14.1).
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. 14.2).
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. 14.3)
Lift the inner rim off the tyre wall (Fig. 14.4).
Lift the tyre and tube off the outer rim. Gently get a hold of the
inner tube just behind the valve.
Carefully feed the tube out of the tyre.
