NOTE:

 If you don’t have cable keepers, then skip this step. Refer to Step 4 Attaching Cable 

Keepers, to determine if you have cable keepers installed.

IMPORTANT: 

CABLE KEEPERS ARE INTENDED TO HELP PREVENT COUNTERBALANCE LIFT 

CABLES FROM COMING OFF CABLE DRUMS ON MANUALLY OPERATED DOORS. ADDITION-

AL CABLE TENSIONING PROVISIONS MAY BE REQUIRED FOR MOTOR OPERATED DOORS.
Rotate arm up and hook around counterbalance lift cable, letting the cable keeper arm pull 

against the counterbalance lift cable, keeping it taut, as shown. Next, close the hook to 

prevent the counterbalance lift cables from coming out.

Attaching Weather Seal

NOTE:

 If you don’t have weather seals, then skip this step. Refer to Package Contents / 

Breakdown of Parts, to determine if you have weather seals.
Permanently attach the weatherstrips on both door jambs and header. The weatherstrips 

were temporarily attached in Preparing the Opening, in the pre-installation section of this 

manual.

NOTE:

 When permanently attaching the weatherstrips to the jambs, avoid pushing the weath-

erstrips too tightly against the face of door.

Balancing Door

 

31

 

Remove locking pliers. Lift door and check its balance. Adjustments to the required number 

of spring turns stated may be necessary. If door rises off floor more than 2 ft. under spring 

tension alone, reduce spring tension. If the door is hard to rise or drifts down on its own, add 

spring tension. A poorly balanced door can cause garage door operator problems.
To adjust spring tension, fully close door. Apply locking pliers to track above third track roller. 

Place locking pliers on torsion shaft, as shown in Step Attaching Counterbalance Lift Cables. 

Insert a winding rod into the winding cone. Push upward on the winding rod slightly while 

carefully loosening the set screws in the winding cone.

IMPORTANT: 

BE PREPARED TO SUPPORT THE FULL FORCE OF THE TORSION SPRING ONCE 

THE SET SCREWS ARE LOOSE.
Carefully adjust spring tension 1/4 turn. Retighten both set screws to 14-15 ft. lbs. of torque 

in the winding cone and repeat for the other side. Recheck door balance and re-adjust spring 

tension if needed.

IMPORTANT: 

DO NOT ADJUST MORE THAN 1 TURN FROM THE RECOMMENDED NUMBER 

OF TURNS.
If the door still does not operate easily, lower the door into the closed position, unwind 

spring(s) completely, and recheck the following items:
1.) Is the door level?
2.) Are the torsion shaft and flag angles / angle mount level and plumb?
3.) Does the distance between the flag angles / angle mount equal door width plus 3-3/8” to 

3-1/2”?
4.) Do the counterbalance lift cables have equal tension? Adjust if necessary.
5.) Rewind the spring(s).
6.) Make sure door is not rubbing on jambs.

IMPORTANT: 

IF DOOR STILL DOES NOT BALANCE PROPERLY, THEN CONTACT A TRAINED 

DOOR SYSTEM TECHNICIAN.

MAINTENANCE

Cleaning Your Garage Door

IMPORTANT: 

DO NOT USE A PRESSURE WASHER ON YOUR GARAGE DOOR!

While factory-applied finishes on garage doors are durable, it is desirable to clean them on 

a routine basis. Some discoloration of the finish may occur when a door has been exposed 

to dirt-laden atmosphere for a period of time. Slight chalking may also occur as a result of 

direct exposure to sunlight.
Cleaning the door will generally restore the appearance of the finish. To maintain an aestheti-

cally pleasing finish of the garage door, a periodic washing of the garage door is recom-

mended.

THE FOLLOWING CLEANING SOLUTION IS RECOMMENDED:

A mild detergent solution consisting of one cup detergent (with less than 0.5% phosphate) 

dissolved into five gallons of warm water will aid in the removal of most dirt.

NOTE:

 The use of detergents containing greater than 0.5% phosphate is not recommended 

for use in general cleaning of garage doors.

NOTE:

 Be sure to clean behind weatherstrips on both sides and top of door.

CAUTION 

NEVER MIX CLEANSERS OR DETERGENTS WITH BLEACH.

GLASS CLEANING INSTRUCTIONS

Clean with a mild detergent solution (same as above) and a soft cloth. After cleaning, rinse 

thoroughly.

ACRYLIC CLEANING INSTRUCTIONS

Clean acrylic glazing with nonabrasive soap or detergent and plenty of water. Use your bare 

hands to feel and dislodge any caked on particles. A soft, grit-free cloth, sponge or chamois 

may be used to wipe the surface. Do not use hard or rough cloths that will scratch the acrylic 

glazing. Dry glazing with a clean damp chamois.

NOTE:

 Do not use any window cleaning fluids, scouring compounds, gritty cloths or solvent-

based cleaners of any kind.

Painting Your Garage Door

SURFACE PREPARATION FOR PAINTING

Wax on the surface must be removed or paint peeling/ flaking will result. To remove this 

wax, it will be necessary to lightly scuff the surface with a fine steel wool pad saturated with 

soapy water. A final wipe and rinse should be done with clean water only to remove any loose 

particles and any soapy film residue.
Surface scratches, which have not exposed the metal substrate, can be lightly buffed or 

sanded with 0000 steel wool or no. 400 sand paper to create a smoother surface. Care must 

be taken to not expose the substrate under the paint. Once the substrate is exposed, the 

likelihood for rusting is greatly increased.
If substrate is exposed, it must be treated to prevent rust from forming. Sand the exposed 

area lightly and paint with a high quality metal primer specifically intended for galvanized 

surfaces to protect the area from corrosion. Allow for drying time on primer can label before 

applying topcoat.
The surface of the factory-applied finish, that is being painted, must not be too smooth, or 

the paint will not adhere to it. It is advisable to test in an inconspicuous area, to evaluate 

adhesion. If poor adhesion is observed, surface preparation for painting the factory-applied 

finish must be repeated until desired results are achieved. Again, care must be taken to not 

expose the substrate under the paint.

PAINTING:

After surface has been properly prepared, it must be allowed to dry thoroughly, and then 

coated immediately with premium quality latex house paint. Follow paint label directions 

explicitly. Oil base or solvent base paints are not recommended. Please note that if substrate 

is exposed and not properly primed, painting with latex paint may cause accelerated rusting 

of the steel in the exposed area.

NOTES:

1. Re-painting of finish painted steel doors cannot be warranted, as this condition is totally 

beyond the door manufacturer’s control.
2. Consult a professional coatings contractor if in doubt about any of the above directions.
3. Follow directions explicitly on the paint container labels for proper applications of coatings 

and disposal of containers. Pay particular attention to acceptable weather and temperature 

conditions in which to paint.

Operation And Maintenance
