Adjustment

STEP 1

LIMIT ADJUSTMENT settings regulate the points at which the
door will stop when moving up or down.

NOTE: Door STOPS in the UP direction if anything interferes
with door travel. Door REVERSES in the DOWN direction if
anything interferes with the door travel (including binding or
unbalanced doors).

PROCEDURE: To operate opener, press wall push button. Run
the opener through a COMPLETE TRAVEL CYCLE. Limi
adjustments are not necessary when the door opens and closes
completely and doesn't reverse unintentionally in the fully closed
position.

The following chart outlines adjustment procedures. Run the opener through a COMPLETE TRAVEL CYCLE AFTER EACH
ADJUSTMENT. NOTE: REPEATED OPERATION OF THE OPENER DURING ADJUSTMENT PROCEDURES MAY CAUSE MOTOR
TO OVERHEAT AND SHUT OFF. SIMPLY WAIT 15 MINUTES AND TRY AGAIN. Read chart carefully before proceeding to Step 2. Use a

screwdriver to make limit adjustments.

LIMIT ADJUSTMENT CHART

IF DOOR DOES NOT OPEN COMPLETELY

BUT IT OPENS AT LEAST FIVE FEET

Increase UP travel. Turn the UP LIMIT adjustment screw

clockwise. One turn equals 2" of travel.

If door does not open at least 5 feet: adjust OPEN FORCE as
explained in Step 2.

IF SECTIONAL DOOR DOES NOT CLOSE COMPLETELY

Increase DOWN travel. Turn down limit adjustment screw
counterclockwise. One turn equals 2" of travel.
If the door still will not close completely, the header bracket is
positioned too high. Repeat Step 1, page 7.

IF ONE-PIECE DOOR DOES NOT CLOSE COMPLETELY

Increase DOWN travel. Turn down limit adjustment screw
COUNTERCLOCKWISE One turn equals 2 inches of travel.

IF OPENER REVERSES IN FULLY CLOSED POSITION

Decrease DOWN travel. Turn down limit adjustment screw
clockwise. One turn equals 2" of travel.

IF DOOR REVERSES WHEN CLOSING AND THERE

IS NO INTERFERENCE TO TRAVEL CYCLE

Test door for binding: Pull emergency release handle. Manually

open and close door. If door is binding, call a door serviceman. If
door is not binding or unbalanced, adjust CLOSE FORCE. See
Step 2.

STEP 2

DO NOT USE FORCE ADJUSTMENTS TO COMPENSATE FOR A BINDING OR STICKING GARAGE DOOR.
EXCESSIVE FORCE WILL INTERFERE WITH PROPER OPERATION OF SAFETY REVERSE SYSTEM OR DAMAGE
GARAGE DOOR.

Force Adjustment Controls are located on rear panel of opener.
FORCE ADJUSTMENT settings regulate amount of the power
required to open and close door.

NOTE: The door STOPS in the UP direction if anything
interferes with its travel. Door REVERSES in the DOWN
direction if anything interferes with its travel (including
binding or unbalanced doors).

If the force adjustments are set too light, door travel may be
interrupted by nuisance reversals in DOWN direction and stops in
UP direction. As weather conditions can affect the door movement,
occasional adjustment may be needed.

Maximum force adjustment range is 260 degrees, about 3/4 of a
complete turn. Do not force controls beyond that point. Turn force
adjustment controls with a screwdriver.

FORCE ADJUSTMENT CHART

TEST DOWN (CLOSE) FORCE

Grasp the door handle or door bottom when door i s about halfway
through DOWN (CLOSE) TRAVEL. Door should reverse. If the
door is hard to hold or doesn't reverse, decrease DOWN (CLOSE)
FORCE by turning the control in a counterclockwise direction.
Make 10 degree turn adjustments until door reverses normally.
After each adjustment, run opener through a complete cycle.

STEP 3

THE SAFETY REVERSE SYSTEM TEST IS IMPORTANT. GARAGE DOOR MUST REVERSE ON CONTACT WITH A
ONE INCH OBSTACLE PLACED ON THE FLOOR. FAILURE TO PROPERLY ADJUST OPENER MAY RESULT IN
SERIOUS PERSONAL INJURY FROM A CLOSING GARAGE DOOR. REPEAT TEST AT LEAST FOUR TIMES A YEAR
AND ADJUST AS NEEDED..

PROCEDURE: Place a 1-inch obstacle on the floor under the

garage door. Operate door in DOWN direction. The door must
reverse on the obstruction.

If a the door STOPS on the obstruction, it is not traveling far
enough in the DOWN direction. Increase the DOWN limit by
turning DOWN limit adjustment screw counterclockwise 1/4 turn.
REPEAT TEST.

NOTE: Make sure limit adjustments do not force the door
arm beyond a straight up and down position. See the
illustration on Page 13.

When the door reverses on the 1-inch obstacle, remove the
obstruction and run the opener through a complete travel cycle.
Door MUST NOT reverse in closed position. If it does, repeat
Adjustment Steps 1, 2 and 3.

Test Safety Reverse System

REPEAT ADJUSTMENT STEP 3 AFTER:

• EACH ADJUSTMENT OF DOOR ARM LENGTH, CLOSE FORCE OR DOWN LIMIT.

• ANY REPAIR OR ADJUSTMENT OF GARAGE DOOR (INCLUDING SPRINGS AND HARDWARE).

• ANY REPAIR OR BUCKLING OF THE GARAGE FLOOR.

• ANY REPAIR OR ADJUSTMENT OF THE GARAGE DOOR OPENER.

(Optional)

The PROTECTOR SYSTEM provides an ADDITIONAL
measure of safety against a small child being caught under a
garage door. It uses an invisible beam which, when broken by an
obstruction, causes a closing door to open and prevents an open
door from closing.

After the garage door opener has been completely installed and
adjusted, the PROTECTOR SYSTEM accessory can be
installed. Instructions are included with this optional device.
