TESTING THE DOOR
4
Complete 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
door.
• Lift the door to about halfway and then release it. The
door should remain spring balanced.
• Raise and lower the door to determine if there are any
sticking or binding points (20kgF is the absolute maximum
allowable to raise or lower the door in any position).
• If your door does not hold in place or the door binds, sticks
or requires excessive force to move, call a qualified door
technician before installing the opener.

the opener is to be installed.
• Fit the stop collar hard against the boss of the door
drum. Ensure the U-bolt holding the door shaft to the door
bracket is tightly secured.

THE RELEASE HANDLE & CORD
• Thread one end of the rope through the hole in the top
of the red release handle so that “NOTICE” reads
right side up as shown.
• Secure with an overhand knot at least 25mm from the
end of the rope to prevent slipping.
• Thread the other end of the rope through the loop of
the manual release cable.
• Adjust rope length so the handle (when installed) will
be no higher than 1.8m above the floor. Secure with
an overhand knot.
NOTE: Final adjustment of handle height should be
completed after the opener is installed. If it is
necessary to cut the rope, heat seal the cut end to
prevent unravelling (refer section 13).
