Preparing your garage door
Before you begin:
• Disable locks.
• Remove any ropes connected to garage door.
• Complete the following test to make sure your garage door is
balanced and is not sticking or binding:
1. Lift the door about halfway as shown. Release the door.
If balanced, it should stay in place, supported entirely by its
springs.
2. Raise and lower the door to see if there is any binding or
sticking.

systems technician.
