START BY READING THESE IMPORTANT SAFETY INSTRUCTIONS

WARNING

•Failuretocomplywiththefollowinginstructionsmayresultin serious injuryorproperty damage.

• Read and follow all instructions carefully.

• The garage door opener is designed and tested to offer safe service provided it is installed and
operated in strict accordance with the instructions in this manual.

These safety alert symbols mean WARNING : A possible risk to personal safety or
property damage exists.

Keep the garage door balanced. Do not let the
garage door opener compensate for a binding or
sticking garage door. Sticking, binding or
unbalanced doors must be repaired before
installing this opener.

Do not wear rings, watches or loose clothing

while installing or servicing a garage door
opener. Wear gloves and suitable protective
clothing where appropriate.

Frequently examine the door installation. In
particular examine cable, springs and mountings
for signs of wear, damage or imbalance. Do not
use if repair or adjustment is needed since springs
and hardware are under extreme tension and a
fault can cause serious personal injury.

To avoid serious injury from entanglement,

remove all ropes, chains and locks connected
to the garage door before installing the door

opener.
Installation and wiring must be in compliance

with your local building and electrical codes.

The safety reverse system test is very
important. Your garage door MUST reverse on

contact with a 40 mm obstacle placed on the
floor. Failure to properly adjust the opener may
result in serious injury from a closing garage
door. Repeat the test once a month and make

any necessary adjustments.

This appliance should not be used by children or
persons with reduced physical, sensory or mental
capablities, or a lack of experience & knowledge,
unless they have been given supervision or
instruction concerning use of the appliance by a
person responsible for their safety.

The opener must not be used on a wicket
door (door within a door).

The Protector SystemTMmust be used for all
installations where the closing force as
measured on the bottom of the door is over
400 N (40 kgf). Excessive force will interfere

with the proper operation of the safety reverse
system or damage the garage door.

After installation, ensure that the parts of
the door do not extend over public
footpaths or roads.

Install the wireless wall control (or any
additional wall control) in a location where

the garage door is visible away from
moving parts, at a height of at least 1.5 m
and out of the reach of children. Do not
allow children to operate push buttons or
transmitters. Serious personal injury from a

closing garage door may result from misuse of
the opener.

Permanently fasten the warning labels in
prominent places, adjacent to wall controls

and manual release mechanisms as a
reminder of safe operating procedures.

Activate opener only when the door is in
full view, free of obstructions and the
opener is properly adjusted. No one should
enter or leave the garage while the door is
in motion.

Do not allow children to play near the door
or with door controls.

If the power cable is damaged, it must be
replaced by the manufacturer, its service
agent or similarly qualified persons in order to
avoid hazard.

Automatic Drive - Keep away from the area of
the door as it may operate unexpectedly.

This opener should not be installed in a damp
or wet space exposed to weather.

NOTE: If your garage has no service entrance door, we recommend an outside quick release must be installed.
This accessory allows manual operation of the garage door from outside in case of power failure.

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 kgf 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.

ATTACHING THE STOP COLLAR

• The stop collar is required to be installed on the
opposite side of the door to where the opener is to be
installed.

• Ensure the U-Bolt holding the door shaft to the door
bracket is tightly secure.

(NOTE: This U-Bolt must not be removed or loosened)

• Remove the bolt assembly from the plastic stop
collar. Open the collar as wide as possible and push
it onto the door shaft.

• Fit the stop collar hard against the boss of the
door drum. Reinstall the bolt assembly onto the
stop collar and tighten.

ATTACHING THE WEIGHT BAR

If the door has a lifting handle, remove the handle, nuts &
bolts. Place the weight bar over the handle holes, insert the
extended bolts through the weight bar & fasten the handle
back in place.
