seat height

Übersicht
adjusting front seat height (adjustable
frame, fig.6.11)
1. Slacken the screw (1) and remove
the cover (2). This releases the height
adjustment fixing.
2. By turning the castor connection you
can continuously adjust the seat height
by +/- 1.5 cm. Using the marking (3) on
the castor connection, you can ensure
that both castors are set the same.
3. Ensure that both castors are set at the same
height, otherwise the chair cannot move in a
straight line.
4. Ensure that the bolts (4) always face outwards
and are at right-angles to the direction of travel,
so that it will move in a straight line.
5. Replacing the cover (2) and tightening the
screw (1) secures the height adjustment fixing.
When doing this, be careful to observe the
starting torque.
Adjusting the directional stability (Fig.6.12)
1. Slacken the screw (1) and remove the cover
(2). This releases the height adjustment fixing.
2. Bring the castor fork at right-angles to the
direction of travel and put a set-square onto
the straight surface (3) of the fork.
3. By turning the castor connection, the castor
can be turned inwards or outwards to correct
directional stability.
4. Replacing the cover (2) and tightening the
screw (1) secures the height adjustment fixing.
When doing this, be careful to observe the
starting torque.

wheel alignment

adjusting wheel alignment (fig.6.13 - 6.15)
Important: Your chair will only roll properly if the
rear wheel positions have been opti mized, which
means correct ly adjusting the wheel alignment.
To do this, measure [the distance between] both
wheels front and rear to ensure that they are
parallel to one another. The difference between
both measurements should not exceed 5 mm. To
adjust the wheels to make them paral lel, 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 setting
is necessary only with 3°, 6° and 9°
camber cylinders.

The term "toe-in or toe-out" defines
3
how well the rear wheels of the
chair are aligned in relation to
the ground. This determines how
Fig.6.11
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) plane 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
1
the same on both sides, or there
should be no gap at all. Tighten the
2
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 optionally 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.
