Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the
safety reversing sensors are completely
installed.

 

24

Limit adjustment settings regulate the points at
which the door will 

stop when moving up or down.

The door will 

stop in the up direction if anything

interferes with door travel. The door will 

reverse in

the 

down direction if anything interferes with the

door travel (including binding or unbalanced doors).

To operate the opener, press the Door Control
button/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 (See page 26).

Adjustment procedures are outlined below. Run the
opener through a complete travel cycle after
each adjustment. 

Repeated operation of the opener during adjustment
procedures may cause the motor to overheat and
shut off. Simply wait 15 minutes and try again. 

Read the procedures carefully before continuing on
to Adjustment Step 2. Use a screwdriver to make
limit adjustments.

How and When to Adjust the Limits

• If the door does not 

open completely, but

opens 

at least five feet:

Increase 

up travel. Turn the UP limit adjustment

screw clockwise. One turn equals 2" of travel.

NOTE: To prevent the trolley from hitting the
cover protection bolt, keep a minimum distance
of 2-4" between the trolley and the bolt.

• If door does not open at least 5 feet:

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 2" of travel.

If the door still won't close completely and the trolley
bumps into the pulley bracket (see page 4 or 5), try
lengthening the door arm (see page 22).

If you have adjusted the door arm to the maximum
length and the door still will not close completely,
lower the header bracket. See Installation Step 1,
pages 8 and 9.

• If the opener 

reverses in fully closed position:

Decrease 

down travel. Turn the DOWN limit

adjustment screw clockwise. One turn equals 2" of
travel.

• If the door 

reverses when closing and there is

no visible interference to travel cycle:

If the opener lights are flashing, the Safety Reversing
Sensors are either not installed, misaligned, or
obstructed. See Troubleshooting, page 19.

Test the door for binding: Pull the manual release
handle. Manually open and close the door. If the door
is binding, call for garage door service. If the door is
not binding or unbalanced, adjust the DOWN (close)
force. See Adjustment Step 2.

Adjustment Section:  Pages 24 – 26

Improper adjustment of the travel limits could
interfere with the proper operation of the
safety reverse system. 

The door might not

reverse properly when required and could
seriously injure or kill someone under it. Test
the safety reverse system following all
adjustments to the travel limits. See page 26.
