Adjusting Wheel Alignment
Important: Your chair will only roll properly if the rear
wheel positions have been optimized, which means
correctly adjusting the wheel alignment. To do this,
measure the distance between both wheels front
and rear to ensure that they are parallel to one ano-
ther. The difference between both measurements
should not exceed 5 mm. To adjust the wheels to
make them parallel, loosen the screws and turn the
axle sleeve accordingly. When finished, make sure
that all screws have been properly tightened (see
the page on torque).

3. Setting the toe-in/toe-out to
zero
NOTE: On a wheelchair with 0°
camber cylinders it is not possible
to set toe-in or toe-out. This set-
ting is necessary only with 3°, 6°
and 9° camber cylinders.
The term "toe-in or toe-out" defi-
nes how well the rear wheels of the
chair are aligned in relation to the
ground. This determines how well the chair will run.
Normal resistance or rolling resistance is provided,
when toe-in is set to zero.
To set toe-in/toe-out to zero:
Slacken the 2 screws (1) (1 each side)
which secure the angle tube clamp.
Check the ball in the horizontal (2) pla-
ne and turn the angle tube (3) until the
ball is in the centre. Toe-in is now zero.
Before tightening screws (1), check
that the camber tube is centred left-to-
right. The gap should be the same on
both sides, or there should be no gap
at all. Tighten the screws to 7 Nm.

K. REAR WHEELBASE
The rear wheelbase is defined as
the distance between the upper
side of the rear wheels and the
backrest tubes, and is represented
by measurement X. The factory
setting is (1.25 cm). A bigger gap is
usually required when a sufficient
gap between the tyres and optio-
nally height-adjustable armrests
has to be created.
NOTE: When adjusting the rear wheelbase, adjust first one
wheel then the other. If both sides are slackened at the same
time, the adjustment of toe-in/toe-out will be altered.
To adjust the rear wheelbase, the parts of the camber (4) move
telescopically into or out of the camber tube (5), and lock into
place when they reach the end. Slacken screw (6) (located closest
to the camber tube) on the left side of the chair. Move the quick-
release axle inwards or outwards to achieve the desired wheel-
base. Tighten the screws to 7 Nm. Repeat this procedure on the
right side of the chair and adjust the gap so that it is the same
amount as on the left side.
