START BY READING THESE IMPORTANT SAFETY INSTRUCTIONS
WARNING
• Failure to comply with the following instructions may result in serious personal injury or property 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 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.
Frequently examine the door installation,
particular 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
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
40mm obstacle placed on the floor. Failure to
properly adjust the opener may result in serious
personal injury from a closing garage door. Repeat
the test once a month and make any necessary
adjustments.
This appliance is not intended for use by persons
(including children) with reduced physical, sensory
or mental capablities, or lack of experience and
knowledge,
supervision or instruction concerning use of the
appliance by a person responsible for their safety.
This opener should not be installed in a damp or wet
space exposed to weather.
NOTE: If your garage has no service entrance door, a CM1702 outside quick release must be installed.
This accessory allows manual operation of the garage door from outside in case of power failure.

the opener.
Permanently fasten the Warning Labels in
prominent places, adjacent to wall controls and

while the door is in motion.
Do not allow children to play near the door, or
