5. Once all of the distances are correct, use
an open-ended spanner (AF 22 mm) to
hold the drive wheel bushing in position
and tighten the aluminium locking nuts (AF
41 mm) to a tightening torque of 70
Nm.
19.3 Wheel camber
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
The wheel camber increases the lateral stabil-
ity of the product but also increases the overall
width of the product.
The wheel camber is provided according to the
order and can subsequently be only slightly
adjusted due to the fixed welded caster-wheel
bearing blocks. If you want to make a change
to the wheel camber, please contact your re-
habilitation specialist dealer or PRO ACTIV.
19.4 Tyre pressure
Check the tyre inflation pressure at regular
intervals as well as after extreme influence of
temperature (not on solid rubber tyres). The
maximum and if applicable, minimum tyre
pressure is printed on the side of the tyre
.
This should be observed.
Too low tyre pressure has a negative
effect on the handling. Apart from that, there is
an increased risk of a flat tyre.
The tyre pressure increases with the
temperature. If the pressure is too high, the
tyre may burst. For this reason, product tyres
may not be exposed to unusually high temper-
atures such as under glass in the summer.
When inflating the tyres, make sure that
the prescribed air pressure is not exceeded.
To check or correct the tyre pressure
, pro-
ceed as follows:
1. Secure the product to prevent it rolling
away.
2. The drive wheel is normally fitted with a car
tyre valve. Unscrew the valve cap.

Figure 39: Valve without cap
3. Place the valve attachment of the com-
pressed air device or the compressor onto
the valve (if necessary, an adapter must be
placed on the valve attachment) and, if a
clamp lever is fitted, secure the connection
by applying the lever.
