16 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 qualifi ed garage door
professional adjust or repair the door.
4 To reconnect the operator, fl ip the release lever
up. Raise the door manually until the operator
reconnects.
5 Perform the Safety Beam Test (Section 11).
6 Perform the Safety Reversal System Test as described
in Steps 4-6 in Section 14.
After Servicing the Operator
1 Perform the Safety Beam Test (Section 11).
2 Perform the Open and Close Limit Adjustments
(Section 13).
3 Perform the entire Door Force Safety System Test
(Section 14).
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.

11 Aligning the Infrared Safety Beam
The safety beam has two components, a sender and a receiver. The sender produces a narrow infrared beam that
travels across the bottom of the door opening to the infrared receiver. If an object blocks the infrared beam while the
door is closing, the door will stop, then reverse and fully open (the operator’s light will fl ash three times).
As a safety feature, the operator will ignore signals from all remote controls if the door is open and the
infrared safety beam is blocked or out of alignment. In this case, the door can be forced closed by pressing
and holding the wall station’s up/down arrow pushbutton (be sure the door area is in clear view).
Safety Beam Test
1 Check that the operator has power. The green lights on
the sender and receiver should be lit.
2 If the receiver’s green light is on, but the red light is off,
the receiver has power but is not detecting the infrared
beam from the sender. The red light might fl ash when
the beam is partially detected. This can be caused by
mis-alignment or something blocking the beam. Adjust
the safety beam sender and receiver while watching the
receiver’s red light (stay out of the beam while aligning
it). When the red light stays on, the beam is aligned.
SAFETY BEAM INDICATOR TABLE
GREEN ON POWER ON
GREEN OFF POWER OFF
RED ON BEAM OK - NO BLOCKAGE

➤ NOTE: If the receiver’s red light remains off, check
for: 1) Dirt on the receiver’s lens, 2) Sunlight shining
into the receiver’s lens, 3) A short in the safety beam
wiring (from staples or at the operator terminals).
3 With the door closed and the operator disengaged
from the door, press the wall station’s UP/DOWN
ARROW button to move the traveler (the part on the
belt or chain that the trolley engages with) to the up
position (away from the door).
4 Push the wall station’s UP/DOWN ARROW button
again. While the traveler is moving to the down
position (toward the door), block the safety beam. THE
TRAVELER MUST STOP, THEN REVERSE TO THE
UP POSITION. The operator’s lights should fl ash three
times.
5 Place an object in the path of the safety beam. Check
that constant pressure is required on the wall station’s
UP/DOWN ARROW button to cause the traveler
to move toward the down position. Release the
pushbutton before the operator stops; check that the
traveler returns to the up position.
➤ NOTE: The garage door operator will not respond
to a CLOSE command from a radio transmitter if the
safety beam is blocked.
6 To reconnect the operator, fl ip the release lever
up. Raise the door manually until the operator
reconnects.
12 Remote Controls
The operator 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 wire
on the back of the operator serves as an antenna for the remote controls. Do not cut off the short wire or the remote
controls will not operate well.
To Add a Remote Control
1 Press the operator’s LEARN button. The red LEARN
light will glow. The red light will stay on for about 15
seconds. A remote must be added while the red
LEARN light is still on.
2 Send a signal from a remote. The red LEARN light and
the operator’s lights will fl ash once indicating that the
operator has accepted the remote.
3 Repeat Steps 1 & 2 for any additional remote controls.
To Remove all Remote Controls
1 Press and hold the operator’s LEARN button for ten
seconds or more.
2 Release the LEARN button. The red LEARN light will
blink three times signaling that all of the remotes
in the operator’s memory were erased. The red
LEARN light will turn off, then turn on for 15 seconds.
A remote control can be entered during this time using
Step 2 above.
Testing
1 Before testing the remote control, straighten out the
operator’s short antenna wire so it points up.
2 Stand clear of the door, press the remote control’s
button and verify that the operator starts. PRESS THE
REMOTE CONTROL’S BUTTON AGAIN TO STOP
THE DOOR MID-TRAVEL.
3 Set the open and close limits as described in the
next section before any further testing.
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.
1 Open the remote’s case and remove the circuit board
2 Replace old batteries with two Type 2032 batteries.
3 Re-assemble the remote.
13 Adjusting the Open and Close Limits
The limit adjustments that control how far the door will
open or close are located on the side of the operator. The
limits should be adjusted so the door opens just short of
any door stops, and closes right at the fl oor level. Each
full turn of a limit adjustment equals about 2-½” of door
travel.
1 Activate the remote control. Wait while the door moves
to the open position and stops.
2 Examine the position of the door.
• If the door needs to open more, turn the OPEN LIMIT
adjustment clockwise ¼-turn (towards UP on the label)
to raise the open limit.
• If the door needs to open less, turn the OPEN LIMIT
adjustment counterclockwise ¼-turn (towards DOWN
on the label) to lower the open limit.
3 Activate the remote control. Wait for the door to move
down a few feet, then activate the remote control again
to stop the door.
4 Repeat Steps 1-3 until the open limit is properly
adjusted.
5 Activate the remote control. Wait while the door moves
to the closed position and stops.
6 Examine the position of the door.
• If the door needs to close more, turn the CLOSE
LIMIT adjustment counterclockwise ¼-turn (towards
DOWN on the label) to lower the close limit.
• If the door needs to close less, turn the CLOSE LIMIT
adjustment clockwise ¼-turn (towards UP on the label)
to raise the close limit.
7 Activate the remote control. Wait for the door to move
up a few feet, then activate the remote control again to
stop the door.
8 Repeat Steps 5-7 until the close limit is properly adjusted.
➤ NOTE: If the door stops during opening or reverses
during closing before reaching the limits, the door force
adjustment needs to be set. Change the adjustment as
described in the next section then return to this section
to fi nish setting the limits.
14 Testing & Adjusting the Door Force Safety System
The door force adjustments are located on the side of the
operator. The door force adjustments must be properly
set at all times. The CLOSE FORCE adjustment
controls how much force is required to cause the door to
reverse direction if an obstruction is encountered during
closing. The OPEN FORCE adjustment controls how
much force is required to stop the door if an obstruction is
encountered during opening.
➤ NOTE: Read the following directions carefully before
setting the door force adjustments.
Door Force Safety System Test
1 Start with the door open. Use the remote control to
cycle the door during these tests.
Adjusting the Close Force
2 Turn the CLOSE FORCE adjustment 1/8-turn at a time
in the DECREASE direction (counterclockwise) until the
door stops and reverses mid travel while going down.
3 Turn the CLOSE FORCE adjustment 1/8-turn at a time
in the INCREASE direction (clockwise) until the door
fully closes without reversing.
Safety Reversal System Test
4 Lay a 2 x 4 board fl at on the fl oor where it will be struck
by the center of the door as it closes.
5 Verify that the door reverses when it strikes the board.
The door must reverse within two seconds after
striking the board.
➤ NOTE: If the door stops after encountering the board
and does not reverse, the CLOSE FORCE needs to be
DECREASED.
6 Repeat the Safety Reversal System Test until the door
reverses within two seconds of striking the board.
Adjusting the Open Force
7 Turn the OPEN FORCE adjustment 1/8-turn at a time
in the DECREASE direction (counterclockwise) until
the door stops mid travel while going up.
8 Turn the OPEN FORCE adjustment 1/8-turn at a time
in the INCREASE direction (clockwise) until the door
fully opens without stopping.
