When adjusting the height of the
wheelchair, the height of the driving
wheels should be regulated before the
angle. There is a scale for adjusting
both the height and angle of the castor
wheels, which helps to achieve equal
measurements on both castor wheels.
Adjusting the castor wheel height
Figure 29
The driving wheel has a scale from 1–9
to help achieve the same height on both
castor wheels.
• Loosen screw (29A)
• Adjust to the desired height, see scale
(29B)
• Re-tighten the screw
Adjusting the angle of the castor
wheel
Figure 30
• Loosen screw (30A) slightly
• Loosen screw (30B)
• Place the Allen key into the rotating disk
(30C) and rotate to the desired angle.
See the scale
• Tighten screw (30B). A screw locking
device such as Blue Locktite, no. 243,
can be used.
• Tighten screw (30A)
When the front castor wheel is at the
correct angle, the bearing housing will be
in a vertical position (90°) to the base. This
is achieved by using a right angle to the
bearing house/floor. The bearing housing
level for achieving the correct angle can be
supplied as an accessory (see page 34).
