Travel Limit Adjustments - Sears 39.18205SR - 1/2 HP Owner's Manual

ADJUSTMENT STEP 1
Adjust UP and DOWN Limits
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 the opener, press the
Wall Push Button or transmitter. Run the opener
through a COMPLETE TRAVEL CYCLE. No limit
adjustments are necessary when the door opens and
closes completely and doesn't reverse unintentionally
when fully closed.
The following chart outlines adjustments procedures. Run the opener through a COMPLETE TRAVEL
CYCLE AFTER 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 the chart carefully before proceeding to step 2. Use a screwdriver to make limit adjustments.
IF 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.
If door does not open at least 5 feet: Adjust UP
(OPEN) FORCE as explained in step 2.
IF 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. See Step 1, page 10.
LIMIT ADJUSTMENT CHART
Decrease DOWN travel. Turn down limit adjustment

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
for garage door service. If door is not binding or
