(FIGURE 2)
NOTE: The following procedure is for High Back Captain's
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 position greater than 114
o
RELATIVE TO THE SEAT FRAME, DO NOT op-
erate the wheelchair. Adjust the limit
switch or have the wheelchair serviced
by a dealer or qualified technician, oth-
erwise injury or damage may occur.
1. Place the wheelchair on a level surface.
2. Recline the captain's seat back to a 24
o
to achieve
the 114
o
angle relative to the seat frame. Refer to AD-
JUSTING CAPTAIN'S SEAT in PROCEDURE 5 of
the owner's manual, part number 1080722.
NOTE: The captain's seat frame is at a 5
o
angle relative
to the ground. When the back angle is adjusted to 114
o
relative 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 3 and ad-
just 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.

to adjust the actuator on the upper limit switch bracket:
A. Fully recline the back. Refer to
ADJUSTING
