These safety alert symbols mean Caution – a personal safety or property damage instruction. Read these instructions carefully.
This garage door opener is designed and tested to offer reasonable safe service provided it is installed and operated in strict
accordance with the following safety rules.
Failure to comply with the following instructions may result in serious personal injury or property damage.
Do not use the force adjustments to compensate for a
binding or sticking garage door. Excessive force will
interfere with the proper operation of the Safety Reverse
System or damage the garage door.
Fasten the caution label adjacent to the lighted door
control button as a reminder of safe operating procedures.
Disengage all existing garage door locks to avoid
damage to garage door.
Install the lighted door control button (or any additional
push buttons) in a location where the garage door is
visible, but out of the reach of children. Do not allow
children to operate push button(s) or remote control(s).
Serious personal injury from a closing garage door may
result from misuse of the opener.
Activate opener only when the door is in full view, free
of obstructions and 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.
Use manual release only to disengage the trolley and, if
possible, only when the door is closed. Do not use the
red handle to pull the door open or closed.
Disconnect electric power to the garage door opener
before making repairs or removing covers.
This product is provided with a power supply cord of
special design which, if damaged, must be replaced by a
power supply cord of the same type; such a power
supply cord may be obtained from your local LiftMaster
distributor and must be fitted by a specialist.
START BY READING THESE IMPORTANT SAFETY RULES
Caution: If your garage has no service entrance door, Model 1702E Outside Quick Release must be installed. This accessory allows
manual operation of the garage door from outside in case of power failure.

Keep garage door balanced. Sticking or binding doors
must be repaired. Garage doors, door springs, cables,
pulleys, brackets and their hardware are under extreme
tension and can cause serious personal injury. Do not
attempt to loose, move or adjust them. Call for garage
door service.
Do not wear rings, watches or loose clothing while
installing or servicing a garage door opener.
To avoid serious personal injury from entanglement,
remove all ropes connected to the garage door before
installing the door opener.
Installation and wiring must be in compliance with your
local building and electrical codes. Connect the power
supply cord only to properly earthed mains.
Lightweight doors of fiberglass, aluminum or steel
must be substantially reinforced to avoid door
damage. (See page 4.) The best solution is to check with
your garage door manufacturer for an opener installation
reinforcement kit.
The safety reverse system test is very important. Your
garage door MUST reverse on contact with a 50mm
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 needed adjustments.
This unit should not be installed in a damp or wet
space.
Door must not extend over public byway during
operation.
