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 spring balanced.
• Raise and lower the door to determine if there are any
sticking or binding points (20 kg 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 or
sticks, call a qualified door technician before installing the
opener.

INSTALLING THE STOP COLLAR
• Install the stop collar on the opposite end to where
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.

INSTALLING THE WEIGHT BAR (optional)
• Place the weight in the centre of the door (as shown).
• Use a pencil to mark the two hole positions.
• If the door curtain does not have a handle you will need
to drill two 5.5 mm holes through the two marked
positions, then place the weight bar on the inside of the
door.
• Use the 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.
