19 Garage Door Operator Maintenance
Weather conditions may affect the door operation which could require some re-setting of the operator’s adjustments.
Doors may swell and become heavier during wet periods, door hinges and rollers might bind during cold periods.
To insure safe operation of the door, perform the following tests, including any additional test steps described.
Every Month
1
With the door closed, pull the red release handle to
disconnect the operator from the door.
2 From outside the garage, slowly open the door
manually all the way, and then close it all the way.
Notice if there is any binding, sticking or rubbing. The
door should move smoothly in both directions.
3 Raise the garage door about halfway up. Carefully
release the door and see if the door balances. It
should stay in place. Close the door.
NOTE:
If the garage door is unbalanced or the door
travel isn’t smooth, have a qualified garage door
professional adjust or repair the door.
4
To reconnect the operator, flip the release lever up
and run the operator.
5 Perform the Safety Beam Test (Section 12).
6
Perform the Safety Reversal System Test as
described in Section 16.
After Servicing the Operator
1
Perform the Safety Beam Test (Section 12).
2
Perform the Open and Close Limit Adjustments
(Section 14).
3 Perform the Safety Reversal System Test (Section 16).
Every 6 Months
Check the belt or chain tension.
•
For belt-drive rails, examine the length of the tension
spring in the traveler. It should be about 1” long.
• For chain-drive rails, examine the spacing between
the turnbuckle and the rail. The turnbuckle should be
slightly above the rail.
NOTE:
Too much or too little chain tension will cause
excessive sprocket noise.
Chain Adjustment
If necessary, use the following steps to adjust the chain.
1
Hold the turnbuckle with a flat blade screwdriver and
loosen the two locknuts with a 7/16” end wrench.
2 Twist the turnbuckle to adjust the chain tension.
Adjust the chain until the turnbuckle is sightly above
the rail.
3 Hold the turnbuckle with a flat blade screwdriver and
tighten the two locknuts with a 7/16” end wrench.
Belt Adjustment
The tension spring in the traveler keeps the belt taut.
The factory setting for the tension spring length is .9”
long. If the tension spring is longer than 1”, adjust the
belt.
1
Hold the traveler so the adjustment wheel is visible
through the large slot.
2 Use a flat blade screwdriver to turn the adjustment
wheel to compress the tension spring until its length
is between .9” and 1” long.
Every Year
Check the door hardware for lubrication needs.
Lubricate door hinges, rollers and bearings according
to door manufacturer’s recommended procedures.

IMPORTANT USER SAFETY INSTRUCTIONS
WARNING
A MOVING GARAGE DOOR CAN CAUSE INJURY OR DEATH!
TO REDUCE THE RISK OF DEATH OR SEVERE INJURY:
1 READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2 NEVER LET CHILDREN OPERATE, OR PLAY WITH DOOR CONTROLS! KEEP REMOTE CONTROL AWAY FROM CHILDREN!
3 Always keep moving door in sight and away from people and objects until it is completely closed.
NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4 NEVER GO UNDER A STOPPED, PARTIALLY OPEN DOOR.
5 Test door operator monthly. The garage door MUST reverse on contact with a 1-1/2 inch object (or a 2x4 board laid flat
at the center of the door) on the floor. If adjusting either the force or the limit of travel, re-test the door operator. Failure
to adjust the operator properly may cause severe injury or death.
6 If possible, use the red emergency release handle only when the door is closed. Use caution when using this release with
the door open. Weak or broken springs may cause the door to fall rapidly, causing injury or death.
7 KEEP GARAGE DOORS PROPERLY BALANCED. (See Garage Door Operator Maintenance) An improperly balanced door
could cause severe injury or death. Have a qualified service person make repairs to cables, spring assembly and other
hardware.
8 This operator system is equipped with an unattended operation feature. The door could move unexpectedly. NO ONE
SHOULD CROSS THE PATH OF THE MOVING DOOR. Only use the Smart Control wall station for unattended operation when
installed with a sectional residential overhead door.
9
SAVE THESE INSTRUCTIONS.
WARNING
The garage door operator must not be
installed and used on an unbalanced door. The
operator’s internal door force sensor will not
function properly on an unbalanced door. Risk
of serious injury or death may result.
WARNING
Garage door hardware (springs, cables,
brackets, pulleys, etc.) are under extreme
pressure and tension. DO NOT ATTEMPT
TO LOOSEN, TIGHTEN OR ADJUST ANY DOOR
HARDWARE. CALL A QUALIFIED GARAGE DOOR
INSTALLATION PROFESSIONAL!
WARNING
Always perform the Safety Reversal System
Test (see Section 16) after making any
adjustments to the operator.
