The castor fork adjustment mechanism has three settings:
• Castor fork angle
• Directional stability
• Castor fork height
The settings for directional stability and the castor fork height
are combined; by twisting the slightly angled castor axis (A)
(Fig. 1), the fork moves inwards (B) or outwards (C) (Fig. 2). At
the same time, the distance of the fork from the frame also
changes by 1 mm for every full rotation of the castor axis.
The detailed instructions for making the adjustments are
described in the following section.
NOTE: The following adjustments may only be made by
Sunrise Medical dealers
NOTE: You can also find a service video about this on the Sun-
rise Medical YouTube channel
WARNING:
• Faulty adjustments, or adjustments that have not been
carried out correctly, may cause damage to the wheelchair
or result in a fall and severe injuries to the user and other
people.
• Wherever torque settings are specified, it is strongly
recommended that a torque meter (not included), is used to
verify correct torque specification is achieved.
• Some of the screws that are used during manufacture are
fitted with threadlock, (blue dot on the thread) and can be
undone and re-tightened up to three times before they must
be replaced with new screws and threadlock. Alternatively,
you can put Loctite™ 243 threadlock on the screws and
re-fit them.

Assembly and adjustment instructions for castor fork
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)
