INSTALLATION INSTRUCTIONS

Do not install this opener or any other opener on "HIGH RISK" garage doors that may cause severe injury, entrapment or death!

See back page for serious injuries which may occur if “HIGH RISK” areas are left uncorrected. 

Martin Finger Shield Garage Doors are “Low Risk”.

Untrained or Negligent

 Installing, Adjusting and Servicing can be Dangerous!   The 

garage door springs and related parts can cause serious injury or death!   IF YOU ARE 
UNSURE, CALL A TRAINED MARTIN DOOR DEALER!

Garage door 

should be balanced and easy to open and close by hand.   

Locks 

should be disabled and pull down ropes should be removed.

Locate 

wall control/push button within sight of door, at min. height of 5' (1520) so 

small children cannot reach it, and away from all moving parts of door.  See Step 8.

Emergency release tag

 should be installed above knob and adjusted to about 

6' (1830) above the floor.  Opener should be 7’ (2130) above floor. See Step 9.

Risk of electrical shock

 is explained in Step10.  Do not connect opener to source 

of power until instructed to do so.

Entrapment

 

and warning labels

 should be installed next to the wall control/push 

button as explained in Step 14.

IMPORTANT

MAINTENANCE & SAFETY INSTRUCTIONS 

Monthly,

 check the opener's down cycle safety reverse.   The door must reverse when it 

contacts a 1 1/2" (38) high object (or a 2X4 board laid flat) on the floor, in line with the door 
opener.  A closing door must also reverse if the photo eyes are interrupted.  See Steps 12,13.

Always 

keep the moving door in sight and away from people and objects until it is 

completely closed.  NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.

Do not allow children

 to operate or play with the garage door controls. Keep the remote 

control away from children.

The emergency release

 should only be used when garage door is in the closed position. 

Weak or broken springs may cause door to fall if released in the open position, increasing 
the risk of severe injury or death. Use caution when using the release with door open. 

Monthly 

visually check the lift cables, spring assembly, hardware, etc. for wear and stability.

If the Safety Reverse

 or any other part of the garage door and opener system do not work 

properly, or if you do not understand, call a trained Martin Door Dealer.

DEATH, READ AND FOLLOW ALL INSTRUCTIONS
