To prevent damage to the garage door and opener:
• ALWAYS disable locks BEFORE installing and operating the
opener.
• ONLY operate the garage door opener at 230 - 240 V, 50 Hz or
battery power to avoid malfunction and damage.
To prevent possible SERIOUS INJURY or DEATH:
• ALWAYS call a qualified door technician if garage door binds,
sticks, or is out of balance. An unbalanced garage door may not
reverse when required.
• NEVER try to loosen, move or adjust garage door, door springs,
cables, pulleys, brackets or their hardware, ALL of which are
under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected to garage
door BEFORE installing and operating the garage door opener to
avoid entanglement.
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 (15 kgf is the absolute maximum
allowable to raise or lower the door in any position).
If your door binds, sticks, or is out of balance, call a
qualified door technician.
