Travel Limit Adjustment
!
WARNING
To prevent SERIOUS INJURY or DEATH from improper Force Adjustment:
- Improper adjustment of travel limits will cause operation of safety reversal mechanism.
- If Travel limit adjustment is made, Force Adjustment may also be needed.
- After ANY adjustments, the Safety Reverse Test MUST be performed to ensure the door reverses on
contact with a 1-1/2” thick object (2x4* laid flat). *For larger or heavier doors the 2x4 may need to be laid
high side up (3-1/2").
If the door reverses unintentionally
during closing, check below symptoms:
1. The Photo Eye System may be improperly
connected, misaligned or obstructed. The
courtesy light will flash continuously for 30
seconds. Refer to Troubleshooting on P.22.
2. Binding door — Disconnect the door from the
Opener by using the Emergency Release
Handle. Open and close the door manually
and check the following steps.
2.1 If the door is balanced, refer to “Force
Adjustment” to adjust Close force.
2.2 If the door is unbalanced, binding or
jammed, call a trained service person to
adjust the door.

About Travel Limits
Limit Adjustments regulate the position at which the door will
stop when opening and closing.
BEFORE making any adjustments, operate the door by using
the push button or Transmitter. Run the Opener through a
complete cycle.
If the door opens and closes completely without unintended
reversing upon closing — NO adjustment is necessary.
If the door does not open or close at desired positions, proceed
with the instructions below to adjust the travel limits.
Adjusting Travel Limits
Open and Close Limits can be increased (+) or decreased (-) by
turning the corresponding screws on the Opener. Use a “flat
head” screwdriver to make adjustments. One full turn of the
screw is about 2” (5cm) of actual travel.
NOTE: The Opener motor includes an automatic thermal
protection system which will shut down the motor in an overheat
situation. The thermal protector will reset itself once the motor
cools down. Opening and closing the Opener multiple times (in
a short period of time) may cause the motor to overheat and
shut down. If this happens, wait about 15 minutes for the motor
to cool and retry operation.
Setting OPEN (UP) Travel Limit
1. CLOSE the garage door by using either the Transmitter or
Push Button.
2. Adjust the OPEN Limit Screw.
3. OPEN garage door and check for proper adjustment.
4. Repeat steps 1-3 until the door opens to the desired
position. When the door is in the open position, make sure
there is enough clearance for your vehicle(s), and there is
a minimum 2“ (5cm) gap between Trolley and Stop Bolt.
5. Perform Safety Reverse Test on page 18.
If the door does not open past 5 feet (1.5m), follow Force
Adjustment on page 17 to adjust the Open Force.
Setting CLOSE (DOWN) Travel Limit
1. OPEN the garage door by using either the Transmitter or
Push Button.
2. Adjust the CLOSE Limit Screw.
3. CLOSE the garage door and check for proper adjustment.
4. Repeat steps 1-3 until door closes to the desired position.
5. Perform Safety Reverse Test on page 18.

Adjusting Force
1. Force Adjustment controls are located on the rear panel of
the Opener. The force adjustments regulate the amount of
force required to open or close the door.
2. Force Adjustment is applied only to compensate for the minor
resistance caused by weather or other means.
Note: Force is preset at level 6 for both Open and Close
adjustments. The size and operating conditions of the
garage door will determine the correct level of Force/
Sensitivity. Weather conditions may also affect the operation
of the door requiring further adjustments as needed.
Note: If the close force is set too light the Opener will reverse
the door during closing. If the open force is set too light the
Opener will stop the door during opening.
Note: There are 12 levels for open and close force settings.
When either the maximum or minimum level is reached, the
light will flash 6 times.
Never adjust the force setting by more than 1 level (1 press)
at a time.
Setting Force
Setting Close Force
1. If the door completes a full close cycle without reversing,
decrease (-) the Close Force by 1 level at a time until the
door reverses. If the door reverses during closing, increase
(+) Close Force by 1 increment. The Close Force is now
properly adjusted.
2. During the ”door-close” cycle, the Opener will reverse if the
force required to close the door is exceeded.
Setting Open Force
1. If the door completes a full open cycle without stopping,
decrease (-) the amount of force by 1 level until the door
stops during the opening. Once the door stops during
opening, increase (+) Open Force by 1 increment. The Close
Force is now properly adjusted.
2. During the “door-open” cycle the Opener will stop if the force
required to open the door is exceeded.
Force Adjustment
!
WARNING
To prevent SERIOUS INJURY or DEATH from improper Force Adjustment:
- DO NOT adjust force to compensate for binding or sticking of the garage door. Call a qualified garage door service
technician to make necessary adjustments in case of binding.
- DO NOT increase the force beyond minimum force required for closing the door. Too much force will
cause improper operation of safety reversal mechanism.
- If either the Force or Travel limit adjustment is made, the other adjustment may also be needed.
- After ANY adjustments, the Safety Reverse Test MUST be performed to ensure the door reverses on
contact with a 1-1/2” thick object (2x4* laid flat). *For larger or heavier doors the 2x4 may need to be laid high side
up (3-1/2").
For safe operation, the force setting should
always be set at the MINIMUM FORCE
required to run the door.

Final Adjustments and Testing
!
WARNING
To prevent SERIOUS INJURY or DEATH from a closing garage door:
- The Safety Reversal Test MUST be conducted ONCE A MONTH.
- NO ONE should cross the path of moving door during operation and/or testing.
- If either Force or Travel limit adjustment is made, the other adjustment may also be needed.
- After ANY adjustments, the Safety Reverse Test MUST be performed to ensure the door reverses on contact
with a 1-1/2” thick object (2x4* laid flat). *For larger or heavier doors the 2x4 may need to be laid high side up (3-1/2").

Testing the Safety Reverse System
The Safety Reverse System prevents the door from closing
when an obstruction is present.
1. Open the door by using the Push Button or Transmitter.
2. Place a 1-1/2” (3.8cm) thick solid object (or 2x4* laid flat) on
floor under the center of garage door. *For larger or heavier
doors the 2x4 may need to be laid high side up (3-1/2").
3. Keeping the door in sight, use the Push Button or
Transmitter to close the door.
4. The door MUST REVERSE upon striking the object within
1.5 seconds, and stop at the fully opened position.
5. The courtesy light will start flashing for 30 seconds upon
triggering the Safety Reverse System.
If the door just stops on the object, adjust the Opener as
follows:
The close travel maybe inadequate, Increase Close travel limit
by 1/4 turn (See Limit Adjustment on page 16).
Conduct the test again. If the door reverses on contact, remove
the object and run at least 3 COMPLETE travel cycles to ensure
proper adjustment.
If the door still does not reverse on the object, decrease the
Close Force (see Force Adjustment on page 17) and repeat
the test.
If the Opener still fails the Safety reverse Test, call a qualified
technician for door adjustment.
Testing the Photo Eye Safety System
1. Open the door by using the Push Button or Transmitter
2. Make sure both Photo Eyes steadily emit the green and red
indicator lights. (If not, check alignment)
