C. FINAL ADJUSTMENTS
The power door operators are shipped with the actuator arms in the "Open" position. To make certain that the vehi-
cle doors are opened and closed properly, it may be necessary to adjust the actuator rod length and limit switches.
If more than one power door operator is installed in the same vehicle, adjust the operators one at a time and repeat
the procedure for the other operator. To adjust the power door operators, follow this procedure:
1. Assemble hex-rod assembly between the door operator actuator arm and clevis bracket.
2. Refer to
Figure 2-6 . With the actuator arm pointing inward INTO the door jam (the "open" position), the
door operator mechanical stop located on the spur gear should make contact with the main plate adjustable
setscrew. If not, with the "open" limit switch mounting position centered between its adjustment slot, turn
setscrew clockwise to decrease the "open" door travel limit, or counter-clockwise to increase the "open"
door travel limit.
3. Deploy the lift or ramp with the control pendant. Verify proper “door open position” of the power door opera-
tor and readjust setscrew as required.
4. Stow the lift or ramp with the control pendant. Verify proper “door closed position” of the power door opera-
tor (the actuator arm is pointing outward AWAY from door jamb.)
5. At the "closed" position, the limit switch should be tripped by the spur gear mechanical stop. If not, loosen
the limit switch mounting screws and slide the switch up or down until it contacts the mechanical stop (the
switch will “click”). The top limit switch mounting screw position should be approximately 1/4" from top of
adjustment slot. Tighten mounting screws sufficiently to allow the switch to be adjusted.
6. Verify proper opening and closing by repeating the above steps.
7. Tighten limit switch mounting screws.
