Top Door Hinges
NOTE:
Obtain assistance from 1 or 2 additional people when removing the top door.
1. Make sure the VLS is powered OFF and unplugged.
2. Open the Top Door and locate the two hydraulic pressure cylinders. Remove the retaining clips from the
top of each.
3. Once the retaining clip has been removed the hydraulic pressure cylinder can be removed by pulling
outward from the door.
7. Locate the 12 window nuts and remove them with a needle nose pliers, as shown. Set the window nuts
aside in a safe place.
8. With the top door still on a flat surface, carefully remove all four Glass Window Mounts by gently prying
them with your fingers. The Glass Window Mounts may stick on the top door window.
9. Remove the glass window from the top door frame.
10. Installation of the Top Door is opposite of removal.
11. Plug in and power ON the VLS. Open and close the door. Check to see if the door open light on the
keypad turns on and off (red flashing light) when you open and close the door. Or check the UCP to see
if the system is indicating that a door is open.
