SECTION 13—WIRING HARNESS
136
Adjusting Limit Switch
NOTE: For this procedure, refer to FIGURE 13.3.
NOTE: The following section is for high back van seat model wheelchairs only.
WARNING
NEVER operate the wheelchair while in any recline position over 114° RELATIVE
TO THE SEAT FRAME. If the limit switch does not stop the wheelchair from oper-
ating in a recline position greater than 114° RELATIVE TO THE SEAT FRAME, DO
NOT operate the wheelchair. Adjust the limit switch BEFORE using the wheelchair,
otherwise injury or damage can occur.
1. Place the wheelchair on a level surface.
2. Recline the van seat back to a 24° to achieve the 14° angle relative to the seat frame.
Refer to Adjusting Van Seat in the User Manual, part number 1104782 or 1123757.
NOTE: The van seat frame is at a 5° angle relative to the ground. When the back angle is adjusted
to 114° relative to the seat, it will measure 61° relative to the ground.
NOTE: To determine 114° back angle relative to the seat frame, place a magnetic protractor
(available at any hardware store) on the back as shown in FIGURE 13.2 and adjust the back until
the magnetic protractor reads 61°.
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 Van Seat in the User Manual, part
number 1104782 or 1123757.
NOTE: This will make access to the limit switch easier.
B. Loosen, but DO NOT remove, the two phillips screws, washers and locknuts that
secure the actuator to the upper limit switch bracket.
C. Slide the actuator up (towards the top of the wheelchair).
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 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 van seat back is
at a 24° angle.
