This opener is supplied with a three-button remote control (the second and third buttons can be used to control an
additional operator or gate if it contains a Linear MegaCode™ receiver). Additional single and multi-button remote
controls can be purchased. An unlimited number of remote controls can be used with this operator. The short white

the remote controls. Do not cut off the white wire or the
remote controls will not operate well.

2
Replace old batteries with two Type 2032 batteries.
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
1
With the door closed, pull the red release handle to
disconnect the opener 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 qualifi ed garage door
professional adjust or repair the door.
4
To reconnect the opener, fl ip the release lever up.
Raise the door manually until the opener reconnects.
5
Perform the Safety Beam Test (Section 4).
6
Perform the Safety Reversal System Test as described
in Steps 4-6 in Section 6.
After Servicing the Opener
1
Perform the Safety Beam Test (Section 4).
2
Perform the Open and Close Limit Adjustments
(Section 5).
3
Perform the entire Door Force Safety System Test
(Section 6).
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 fl at 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 fl at 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 fl at 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.
