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, (Fig.14.1).
14.1.3 drive wheel tyre repair
to remove the wheel/tyre
:
Please see below and next page for photographs.
Use a 8.0 mm hex key to loosen the 3-Socket studs,
•
(
Fig. 14.2
).
Jack the wheel up and support it using blocks,
•
(
•
Fig. 14.3
).
Remove the 3 studs and pull the wheel away from
•
the hub.
Remove the valve cap and let the air out of the tyre
•
by gently pressing the valve stem with a small screw
driver, (
Fig. 14.4
).
There are 6 rim studs that must be loosened/
•
tightened in the number order shown, (Fig.14.5).
Use a 5.0 mm Allen key to release/tighten the studs.
•
(
Fig. 14.5
) .
Lift the inner rim off the tyre wall
•
(
Fig. 14.6
).
Lift the tyre and tube off the outer rim, (Fig.14.7).
•
Gently get a hold of the inner tube just behind the
•
valve.
Carefully feed the tube out of the tyre, (fig.14.8).
•
Ensure all parts are clean before reassembling,
•
(Fig.14.9).
to refit
Place the tube inside the tyre and rest the tyre on
•
the outer rim.
Align the valve stem with the cut out in the rim.
•
Face the valve stem outward.
•
Place the inner rim over the tyre, tube and outer rim.
•
Align the cut out to fit over the valve stem and match
•
it up to the cut out in the outer rim, (Fig.14.10).
Make sure the stud mounts are in line on both rims.
•
Tighten the studs in the sequence shown in Fig.14.5,
•
taking care not to pinch the tube.
Slowly inflate to the pressures quoted in section
•
14.1.1 .
Refit the wheel back onto the motor shaft and fix it
•
safely with the 3 studs to a torque of 47Nm.
For solid tyres the sequence is the same, just discount
the references to the inner tube and valve.
