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. If the door is greater than 2.5m in
height the release cord extension kit accessory is
required.
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 16).

PINNING THE DOOR
Note: A ballooning door may delay the safety reversal
response and can compromise garage door security.
• To remedy any ballooning place self tapping metal screws
or rivets where the curtain leaves the roll. Secure these
through the curtain into the drum wheel at each end of the
roll.
• After determining the correct fastener location as shown, lift
the door approximately half a turn from the closed position
to allow access for drilling.
