ADJUSTMENT STEP 1

Adjust the UP and DOWN Travel Limits

Limit adjustment settings regulate the points at which the 
door will stop when moving up or down.

To operate the opener, press the door control push bar. Run 
the opener through a complete travel cycle.

•  Does the door open and close completely?

•   Does the door stay closed and not reverse unintentionally 

when fully closed?

If your door passes both of these tests, no limit adjustments 
are necessary unless the reversing test fails (Adjustment 
Step 3, page 29).

Adjustment procedures are outlined below. Read the 
procedures carefully before proceeding to Adjustment 
Step 2. Use a screwdriver to make limit adjustments. 

Run 

the opener through a complete travel cycle after each 
adjustment. 

NOTE: 

Repeated operation of the opener during adjustment 

procedures may cause the motor to overheat and shut off. 
Simply wait 15 minutes and try again. 

NOTE: 

If anything interferes with the door’s upward travel, 

it will stop. If anything interferes with the door’s downward 
travel (including binding or unbalanced doors), it will 
reverse.

HOW AND WHEN TO ADJUST THE LIMITS

•   If the door does not open completely but opens at least 

fi ve feet (1.5 m):

 

 Increase up travel. Turn the UP limit adjustment screw 
clockwise. One turn equals 3" (7.5 cm) of travel.

 

 NOTE: 

To prevent the trolley from hitting the cover 

protection bolt, keep a minimum distance of 2-4" 
(5 cm - 10 cm) between the trolley and the bolt.

•   If door does not open at least 5 feet (1.5 m): 

 

 Adjust the UP (open) force as explained in Adjustment 
Step 2.

•   If the door does not close completely:

 

 Increase down travel. Turn the down limit adjustment 
screw counterclockwise. One turn equals 3" (7.5 cm) of 
travel.

 

 If door still won't close completely and the trolley bumps 
into the pulley bracket (page 4), try lengthening the door 
arm (page 25) and decreasing the down limit.

•   If the opener reverses in fully closed position:

 

 Decrease down travel. Turn the down limit adjustment 
screw clockwise. One turn equals 3" (7.5 cm) of travel.

•   If the door reverses when closing and there is no visible 

interference to travel cycle:

 

 If the opener lights are fl ashing, the Safety Reversing 
Sensors are either not installed, misaligned, or 
obstructed. See Troubleshooting, page 22.

 

 Test the door for binding: Pull the emergency release 
handle. Manually open and close the door. If the door is 
binding or unbalanced, call for a trained door systems 
technician. If the door is balanced and not binding, adjust 
the DOWN (close) force. See Adjustment Step 2.

Without a properly installed safety reversal system, 
persons (particularly small children) could be 
SERIOUSLY INJURED or KILLED by a closing garage 
door.
•  Incorrect adjustment of garage door travel limits 

will interfere with proper operation of safety reversal 
system. 

•  If one control (force or travel limits) is adjusted, the 

other control may also need adjustment.

•  After ANY adjustments are made, the safety reversal 

system MUST be tested. Door MUST reverse on 
contact with 1-1/2" high (3.8 cm) object (or 2x4 laid 
fl at) on fl oor.

To prevent damage to vehicles, be sure fully open door 
provides adequate clearance.
