1. Setting the directional stability:
• Insert special Sunrise Medical tool (C spanner, item no.
66009203-ET) into a ¼" ratchet or torque wrench
• Undo the round nut between the fork and castor connection
with the C spanner (Fig. 3)
• Rotate the castor inwards, place a 90° setting gauge on the
front of the fork and grasp the castor axis between the round
nut and the fork with a flat 19 mm open-end spanner (item
no. 66009203-ET) and rotate it until the front of the fork is
level with the setting gauge (Fig. 4 and Fig. 5).
To do this, rotate it by a maximum of 90° in one direction,
to avoid accidentally changing the height.
• After the adjustment has been made, keep the castor axis in
position with the open-end spanner while tightening the
round nut to a torque of 28 Nm.
Note: The fork angle must be set after adjustment has
been made (see 3. Setting the castor fork angle)

2. Adjusting the height:
If the wheelchair does not stand properly on 4 wheels, i.e. one of
the castors is not completely touching the floor, the height of this
castor should be adjusted as follows:
• Place the wheelchair on a flat surface, such as a worktop or
similar.
• Load the footrest with a weight of approx. 2.5 kg, make sure
that the air pressure is identical in both drive wheels, and
rotate both castors into the straight line position (castors
pointing to the back)
• Insert special Sunrise Medical tool (C spanner, item no.
66009203-ET) into a ¼" ratchet or torque wrench
• Undo the round nut between the fork and castor connection
with the C spanner
• Grasp the castor axis between the round nut and fork with a
flat 19 mm open-end spanner (item no. 66009203-ET) and
rotate it anticlockwise. The castor will be lowered by 1 mm
with each complete turn (360°)
• If the castor axis is rotated by one complete turn (360°), this
will not influence the directional stability. In all other cases,
the directional stability must be re-adjusted. See "1. Setting
the directional stability" for more on this.
• Adjust the castor axis until all 4 wheelchair wheels are
standing firmly on the ground
• After the adjustment has been made, keep the castor axis in
position with the open-end spanner while tightening the
round nut to a torque of 28 Nm.
