ADJUSTING LIMIT SWITCH
(FIGURE 2)
NOTE: The following procedure is for high back captains
van seat model wheelchairs only.
WARNING
NEVER operate the wheelchair while in any
recline position over 114
o
RELATIVE TO THE SEAT
FRAME. If the limit switch does not stop the
wheelchair from operating in a recline posi-
tion greater than 114
o
RELATIVE TO THE SEAT
FRAME, DO NOT operate the wheelchair. Ad-
just the limit switch BEFORE using the wheel-
chair, otherwise injury or damage can occur.
1. Place the wheelchair on a level surface.
2. Recline the captains van seat back to a 24
o
to achieve
the 114
o
angle relative to the seat frame. Refer to AD-
JUSTING CAPTAINS VAN SEAT in PROCEDURE 4 of
the owner’s manual, 1081227.
NOTE: The captains van seat frame is at a 5
o
angle relative
to the ground. When the back angle is adjusted to 114
o
rela-
tive to the seat, it will measure 61
o
relative to the ground.
NOTE: To determine 114
o
back angle relative to the seat
frame, place a magnetic protractor (available at any hard-
ware store) on the back as shown in FIGURE 2 and adjust
the back until the magnetic protractor reads 61
o
.
3. Turn the wheelchair power switch on the joystick to the
ON position.
NOTE: The wheelchair should not operate.
4. IF wheelchair operates, proceed to the following steps
to adjust the actuator on the upper limit switch bracket:
A. Fully recline the back. Refer to ADJUSTING CAP-
TAINS VAN SEAT in PROCEDURE 4 of the
Owner’s Manual, 1081227.
NOTE: This will make access to the limit switch easier.
B. Loosen, but do not remove, the two (2) phillips
screws, washers and locknuts that secure the ac-
tuator to the upper limit switch bracket.
C. Slide the actuator UP (towards the top of the wheel-
chair).
CAUTION
DO NOT over tighten the phillips screws that
secure the actuator to the upper limit switch
bracket. Damage to the actuator can occur.
D. Only tighten the two (2) phillips screws, washers
and locknuts that secure the actuator to the upper
limit switch bracket until the actuator does not move.
E. Repeat STEPS 1-3 until the wheelchair does not
operate when the captains van seat back is at a 24
o
angle.
