REAR SEAT-TO-FLOOR HEIGHT
ADJUSTMENT - A-6/A-6S ONLY
(FIGURE 4)
Rear seat-to-floor height is a measurement taken at the rear
of the seat from the horizontal position, and is measured in
inches. The rear seat-to-floor height of the A-6/A-6S can be
adjusted up to 4-inches below the front seat-to-floor height.
WARNING
The position of the footrest, seat angle, back
angle, seating system/upholstery, caster size and
position, rear wheel size and position, anti-tippers,
as well as the user condition directly relate to the
stability of the wheelchair. Any change to one
(1) or any combination of the ten (10) may cause
the wheelchair to decrease in stability. EXTREME
care MUST be taken when changing the stability
of the wheelchair. Refer to the chart in
STABILITY
in PROCEDURE 1 of this manual.
WARNING
Adjusting the rear seat-to-floor height will change
the back angle with respect to the ground and
may decrease the stability of the wheelchair.
AFTER adjusting rear seat to floor height, ALWAYS
check back angle and adjust if necessary to en-
sure proper wheelchair stability.
DO NOT adjust rear seat-to-floor height with the
wheelchair occupied.
DO NOT adjust the rear seat-to-floor height so the
seat crossmember touches the axle tube.
CAUTION
DO NOT use tools to rotate the jam nut or turn-
buckle. Otherwise, damage to the turnbuckle
or jam nut may occur.
1. Rotate the jam nut COUNTERCLOCKWISE until a
few threads are showing between the jam nut and the
turnbuckle.
2. Rotate the turnbuckle in one of the following man-
ners to adjust the rear seat-to-floor height:
CLOCKWISE - Decreases the rear seat-to-floor height.
COUNTERCLOCKWISE - Increases the rear seat-
to-floor height.
NOTE: QUICK RELEASE LEVERS ONLY - If quick re-
lease levers are on TOP of the axle tube and interfere
with the desired rear seat-to-floor adjustment, the levers
can be repositioned. Refer to
REPOSITIONING QUICK
RELEASE LEVERS in this procedure of the manual.
3. Rotate the jam nut CLOCKWISE until it rests se-
curely against the turnbuckle.
4. The back angle with respect to the floor/ground has
changed. Adjust the back angle to maintain proper
wheelchair stability. Refer to BACK ANGLE ADJUST-
MENT - ADJUSTABLE BACKS ONLY in this proce-
dure of the manual.
