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 114o RELATIVE TO THE SEAT FRAME. If the limit switch does not stop the wheelchair from operating in a recline posi- tion greater than 114o 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 24o to achieve the 114o angle relative to the seat frame. Refer to AD- JUSTINGCAPTAINSVANSEATinPROCEDURE4of the owner’s manual, 1081227.

NOTE: The captains van seat frame is at a 5o angle relative to the ground. When the back angle is adjusted to 114o rela- tive to the seat, it will measure 61o relative to the ground.

NOTE: To determine 114o 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 61o.

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’sManual,1081227.
