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.  \nDo not wear rings, watches or loose clothing while installing or servicing a garage door opener.  \nFrequently examine the door installation,  \nin 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.  \nTo avoid serious personal injury from entanglement, remove all ropes, chainsand locks connected to the garage door before installing the door opener.  \nInstallation and wiring must be in compliance with your local building and electrical codes.  \nThe 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.  \nThis opener should not be installed in adamp or wet space exposed to weather.  \nThis appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.  \nThe opener must not be used on a wicket door (door within a door).  \nThe Protector SystemTM must be used for all installations where the closing force as measured on the bottom of the door is over 400N (40kgf). Excessive force will interfere with the proper operation of the safety reverse system or damage the garage door.  \nAfter installation, ensure that the parts of the door do not extend over public footpaths or roads.  \nInstall the wireless wall control (or any additional wall control) in a location where the garage door is visible, at a height of at least 1.5m and out of the reach of children. Do not allow children to operate push button(s) or transmitter(s). Serious personal injury from a closing garage door may result from misuse of the opener.  \nPermanently fasten the Warning Labels in prominent places, adjacent to wall controls and manual release mechanisms as a reminder of safe operating procedures.  \nActivate 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.  \nDo not allow children to play near the door, or door controls.  \nDisconnect electric power to the garage door opener before making repairs or removing covers.  \nKEEP THESE INSTRUCTIONS  \nNOTE: If your garage has no service entrance door, a 1702AML outside quick release must be installed. This accessory allows manual operation of the garage door from outside in case of power failure.  \nCONTENTS PAGE  \nSAFETY INSTRUCTIONS ........1  \nCARTON INVENTORY ..........2  \nTOOLS REQUIRED ............2  \nDOOR REQUIREMENTS ........2  \nPREPARE & TEST THE DOOR ..3-4  \nINSTALLATION .........","cbCaieBfK8udp2Ac","https://ap.wps.com/l/cbCaieBfK8udp2Ac","pdf",5282005,16,"English","# Safety Instructions\n# Carton Inventory\n# Tools Required\n# Door Requirements\n# Prepare & Test the Door\n# Installation\n# Connect Electric Power\n# Adjustment\n# Install the Protector System (IR Beams)\n# Auto-Close\n# Wireless Programming\n# Special Features\n# Accessories\n# Troubleshooting\n# Operation of Your Opener\n# Care of Your Opener\n# Maintenance of Your Opener\n# Specifications\n# Warranty","[{\"question\":\"What safety reverse test is required for the opener?\",\"answer\":\"The garage door must reverse on contact with a 40mm obstacle placed on the floor.
