2  Remote Controls

This opener is supplied with a three-button remote control (the second and third buttons can be used to control an 
additional opener or gate). Additional single and multi-button remote controls can be purchased. The short wire on 
the back of the opener serves as an antenna for the remote controls. Do not cut off the wire or the remote controls 
will not operate well.

To Add or Remove a Remote Control 

Press the opener’s LEARN button. The opener’s light 

and red light will flash once and turn on for about 15 

seconds. 

A remote must be added or removed 

while the red light is still on.

2  Send a signal from a remote. The opener’s light and the 

red light will flash once if a remote was added, or the 

opener’s light and the red light will flash four times if a 

remote was removed.

3  Repeat Steps 1 & 2 for any additional remote controls.

To Remove all Remote Controls

Press and hold the opener’s LEARN button for ten 

seconds or more.

2  Release the LEARN button. 

The red light and opener’s 

light will blink three times signaling that all of the 

remotes in the opener’s memory were erased.

 The 

red light will turn off, then turn on for 15 seconds. A 

remote control can be entered during this time using 

Step 2 above.

Testing

Before testing the remote control, straighten out the 

opener’s antenna wire so it points up.

2

  Stand clear of the door,

 press the remote control’s 

button and verify that the opener starts. 

Replacing a Remote Control’s Batteries

When the red light on the remote glows dimly, or fails to 
light at all when the remote is activated, the batteries need 
replacing.

Open the remote’s case and remove the circuit board.

2  Replace old battery with a Type CR032 battery.
3  Re-assemble the remote.

3  Garage Door Opener Maintenance

Weather conditions may affect the door operation which 
could require some re-setting of the opener’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

With the door closed, pull the red release handle to 

disconnect the opener from the door.

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.

To reconnect the opener, flip the release lever up and 

run the opener.

5  Perform the Safety Beam Test (Section 4).
6  Perform the Safety Reversal System Test as described 

in Section 8.

After Servicing the Opener

Perform the Safety Beam Test (Section 4).

2 Perform the Open and Close Limit Adjustments 

(Section 5).

3  Perform the Safety Reversal System Test (Section 8).

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.

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.

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.
