TESTING THE DOOR
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 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.

INSTALLING THE STOP COLLAR
• Install stop bracket collar on the opposite end to
where the opener is to be installed.
• Fit the stop bracket hard against the boss of the door
drum. Ensure the U-bolt holding the door axle to the
door bracket is tightly secured.

INSTALLING THE WEIGHT BAR (PROVIDED)
• Place the weight bar in the centre of the door.
• If the door curtain does not have a lifting handle you
will need to drill two 5.5mm holes through the two
marked positions, then place the weight bar on the
inside of the door.
• Use the 5mm bolts, washers and nuts (provided) to
fasten the weight bar in place.
NOTE: If the door has a lifting handle, remove the
handle, nuts & bolts. Place weight bar over the
handle holes, insert extended bolts through the
weight bar & fasten handle back in place.
