omplete the following test to ensure your door is well
balanced, and not sticking or binding:
• Disable all locks and remove any ropes connected to
the garage door.
•
Lift the door to about halfway and then release it. The
door should remain suspended entirely by its spring.
• Raise and lower the door to determine if there are any
sticking or binding points (20 Kgf is the absolute maximum
allowable to raise or lower the door in any position).
• If your door does not hold in place or it binds or sticks,
call a qualified door technician before installing the opener.
