Seat Height; Wheel Alignment - Sunrise Medical Quickie Argon Directions For Use Manual

Options – Seat height
Adjusting front seat height (Adjustable
frame)
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 tor-
que.
Adjusting the directional stability
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 direc-
tion 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 directio-
nal 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 tor-
que.
Options – Wheel Alignment
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-
2
nes how well the rear wheels of the
3
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.
