F:OPERATION AND ADJUSTMENT INSTRUCTIONS IMPORTANT SAFETY INSTRUCTIONS

WARNING	TO REDUCE THE RISK OF SEVERE INJURY OR
	DEATH, READ AND FOLLOW ALL INSTRUCTIONS!

•NEVER let children operate or play with door controls. Keep the Remote Control away from children.

•ALWAYS keep a moving door in sight and keep people and objects away from the door area until the door is completely closed. NO ONE SHOULD CROSS THE PATH OF A MOVING DOOR.

•TEST THE DOOR OPENER MONTHLY. The door MUST reverse upon contact with a 1-1/2” high object (or a 2 X 4 board laid flat) on the floor. After adjusting the sensitivity or the limit of travel, ALWAYS RETEST the Opener. Failure to ADJUST THE OPENER PROPERLY may result in SERIOUS INJURY OR DEATH.

•If possible, USE THE EMERGENCY RELEASE only when the door is closed. Use caution when using the Release with the door open. WEAK OR BROKEN SPRINGS MAY ALLOW THE DOOR TO CLOSE RAPIDLY, CAUSING SEVERE INJURY OR DEATH.

•KEEP THE GARAGE DOOR PROPERLY BALANCED. See the door owner's manual. An improperly balanced door MAY CAUSE SEVERE INJURY OR DEATH. Have a QUALIFIED SERVICE PERSON MAKE REPAIRS TO CABLES, SPRING ASSEMBLIES AND OTHER HARDWARE.

•SAVE THIS INSTRUCTION MANUAL.

NOTE: It is now necessary to turn on the power in order to run the Opener to check limit settings. Before doing so, ensure that all mounting hardware is installed and has been properly tightened, that all electrical connections are per local code requirements, and that proper wiring practices have been followed. Also, double-check that all ropes have been removed from the door and that the doorway is clear.

STEP 1: Testing the Limit Settings: To check the Limit Settings, start the Opener by pushing the standard wall Push Button (Mounted in Step 11). Be prepared to activate the Push Button again quickly - per the Operating Parameters outlined on Page 16 - if you see that the door is going to over travel. As illustrated above, move the Cams toward the Power Unit to DECREASE door travel and toward the Front Idler to INCREASE door travel. Adjust the Up Limit Cam so that the door comes to rest where it normally would without an electric Opener. Adjust the Down Limit Cam so that the door closes firmly without putting undue stress on the Door Arm.

For Models J3000 and J3500, adjust the "Restraining Device To Restrict Forced Door Opening" to the positions as shown when door is fully closed. When properly adjusted, this bracket will inhibit a forced door opening from the center of the door.

WARNING

IF LIMITS ARE NOT ADJUSTED PROPERLY, THE EMERGENCY RELEASE MECHANISM MAY NOT WORK PROPERLY AND DOOR OPERATION COULD RESULT IN DOOR DAMAGE, SERIOUS PERSONAL INJURY OR DEATH!
