Seat Sling
Remove the screws on the left
side of the sling. Adjust the
VELCRO® material to increase
the tension of the seat sling.
Tighten up the screws again.
If the screws are difficult to fit
back in place, try and locate the
holes with a sharp object.
Ensure also that the plastic base is in the correct position
before the screws are tightened again, (Fig.4.16).

Adjusting the Seat Height
(Fig.4.17)
To adjust rear seat height, slacken and remove the 4
screws (1) (2 each side), which
secures the clamp (2) Adjust the two clamps to the
required height and replace the 4 screws. Before
tightening the screws, please follow the instructions for
setting the toe-in/toe-out to zero (See Fig.4.19-4.20).
Tighten the screws to 7 Nm.
NOTE:
An adjustment to the castor angle may be
necessary when adjusting the rear seat height.
Castor, Castor Adapter, Castor Fork
From time to time the wheelchair may veer slightly to the
right or left, or the castors may flutter. This may be caused
by the following:
• The forward or reverse wheel motion has not been set
properly.
• The castor angle has not been adjusted properly.
• Castor and/or rear wheel air pressure is incorrect;
wheels do not turn smoothly.
The optimum adjustment of the castors is required for the
wheelchair to run in a straight line.
Castors should always be adjusted by an authorized
dealer. The castor plates must be re-adjusted, and the
wheel locks must be checked any time the rear wheel
position has been altered.
Castors
Adjusting the Castor
To ensure that both forks are set parallel, simply count the
teeth visible on both sides. After setting the castor fork,
the teeth will guarantee a secure position, allowing an
adjustment of 16° in 2° increments. Use the flat side on
the front of the castor fork to check for a right-angled
position to the ground (Fig. 4.19).
The patented design allows the castor fork to be turned,
so that it can be reset at right-angles to the ground when
the seat angle is changed.
Setting the Directional Stability
Release the Allen screws (1) on the underside of the fork.
You can then undo the screw (2). You can now turn the
black socket (3) left or right.
Left – chair pulls to the left
Right – chair pulls to the right
Then tighten up the screw (2) again. Please set a 90°
angle from the fork to the floor.
Now tighten up the screw (1) again. (Fig. 4.20).
