different. Hanging brackets (1) should be angled (Figure A) to  
provide rigid support. On finished ceilings, (Figure B) attach a sturdy  
metal bracket (not supplied) (4) to a structural support before installing  
the opener. For concrete ceiling mount, (Figure C), use concrete  
anchors (5) provided.  
Wear protective goggles when working overhead to protect your  
eyes from injury.  
Disengage all existing garage door locks to avoid damage to the  
garage door.  
To avoid serious personal injury from entanglement, remove all  
ropes connected to the garage door before installing the opener.  
On each side of opener measure the distance from the opener to the  
structural support (or ceiling).  
Installation of this product shall comply with ZH1/494, VDE 0700  
Part 238, and VDE 0700 Part 1.  
Cut both pieces of the hanging bracket to required lengths. Flatten one  
end of each bracket and bend or twist to fit the fastening angles. Do  
not bend at the bracket holes. Drill 4,5mm (3/16") pilot holes in the  
structural supports (or ceiling). Attach flattened ends of brackets to  
supports with wood screws (2).  
It is recommended that the opener be installed  
2,1m (7 feet) or more above the floor where space permits.  
Lift opener and fasten to hanging brackets with screw, lock washer  
and nut (3). Check to make sure T-rail is centered over the door.  
REMOVE 25mm (1") board. Operate door manually. If door hits the  
rail, raise header bracket.

23  
ADJUSTMENT SECTION  
Press door control button. Trolley will travel to full open position (8).  
Manually raise door to open position (parallel to floor) and lift door  
arm (9) to trolley. The arm should touch trolley just in back of door arm  
connector hole (10) as shown in solid line drawing. Increase up limit  
if necessary. One full turn equals 5cm (2") of door travel.  
21  
LIMIT ADJUSTMENT –  
Closed Door Adjustment: Decrease down limit. Turn down limit  
adjustment screw clockwise 5 complete turns.  
Run the opener through a complete travel cycle. Limit adjustments  
are not necessary when the door opens and closes completely and  
doesn't reverse unintentionally in the fully closed position.  
Press door control button. Trolley will travel to full closed position (11).  
Manually close door and lift door arm (12) to trolley. The arm should  
touch trolley just ahead of door arm connector hole (13) as shown in  
dotted line drawing. Decrease down limit if necessary. One full turn  
equals 5cm (2") of door travel.  
Situations requiring limit adjustment are listed below. Run the opener  
through a complete travel cycle after each adjustment.  
Note: Repeated operation of the opener during adjustment  
procedures may cause motor to overheat and shut off. Allow a  
15 minute cooling period after 5 continuous operations of  
the opener.  
Connect Door Arm to Trolley: With door closed, connect curved arm  
to trolley with remaining clevis pin. Secure with ring fastener.  
Note: Lift door slightly to make connection if necessary.  
Read the following carefully before proceeding to Force Adjustment.  
Use a screwdriver to make limit adjustments.  
Run opener through a complete travel cycle. If door has a slight  
"backward" slant in full open position, decrease up limits until door is  
parallel to floor.  
If Door Doesn't Open Completely but Opens at Least 1,5m  
( 5 feet): Increase up travel. Turn the up limit adjustment screw (1)  
clockwise. One turn equals 5cm (2") of travel.  
If door does not open at least 1,5m (5 feet): Adjust up (open)  
force. See Force Adjustment.  
If Door Doesn't Close Completely: If door arm is at maximum length,  
increase down travel. Turn down limit adjustment screw (2)  
counterclockwise. One turn equals 5cm (2") of travel.  
If the door still will not close completely, the header bracket is  
positioned too high.  
If Opener Reverses in Fully Closed Position: Decrease down  
travel. Turn down limit adjustment screw (2) clockwise. One turn  
equals 5cm (2") of travel.  
If Door Reverses when Closing and there is no Interference to  
Travel Cycle: Test door for binding. Pull manual release handle.  
Manually open and close door. If door is binding, call a door  
serviceman. If door is not binding or unbalanced, adjust down

OPERATION OF YOUR OPENER  
22  
FORCE ADJUSTMENT –  
Your opener can be activated by any of the following devices:  
The force, as measured on the closing edge of the door, should  
not exceed 150 N (15kg). If the closing force is adjusted to more  
than 150 N, the Protector System must be installed.  
• The Lighted Door Control Button (optional). Hold the button down  
until door starts to move.  
Do not use force adjustments to compensate for a binding or  
sticking garage door. Excessive force will interfere with proper  
operation of safety reverse system or damage garage door.  
• The Outside Keylock or Keyless Entry System (if you have  
installed either of these accessories).  
• The Remote Control Transmitter. Hold the push button down until  
the door starts to move.  
Force Adjustment Controls (1 & 2) are located on the back panel of  
opener.  
Opening the Door Manually:  
If the force adjustments are set too light, door travel may be  
interrupted by nuisance reversals in down direction and stops in up  
direction. Weather conditions can affect the door movement,  
occasional adjustment may be needed.  
Door should be fully closed if possible. Weak or broken springs  
could allow an open door to fall rapidly. Property damage or  
serious personal injury could result.  
The door can be opened manually by pulling the release handle down  
and back (toward the opener). To reconnect the door, pull the release  
handle straight down.  
Maximum force adjustment range is 260 degrees, about 3/4 of a  
complete turn. Do not force controls beyond that point. Turn force  
adjustment controls with a screwdriver.  
Do not use the manual release handle to pull the door open  
or closed.  
Test Down (Close) Force: Grasp the door handle or door bottom  
when door is about halfway through down (close) travel. Door should  
reverse. (Reversal halfway through down travel does not  
guarantee reversal on a 25mm (1") obstruction.) If the door is hard  
to hold or doesn't reverse, decrease down (close) force by turning  
the control (2) in a counterclockwise direction. Make small  
adjustments until door reverses normally. After each adjustment, run  
opener through a complete cycle.  
When the Opener is Activated by Remote Control:  
1. If open, the door will close. If closed, the door will open.  
2. If closing, the door will reverse.  
3. If opening, the door will stop (allowing space for entry and exit of  
pets and for fresh air).  
4. If the door has been stopped in a partially open position, it  
will close.  
If Door Doesn't Open at Least 1,5m (5 feet): Increase up (open)  
force by turning the control (1) in a clockwise direction. Make small  
adjustments until door opens completely. Re-adjust  
up limit if necessary. After each adjustment, run opener through a  
complete travel cycle.  
5. If an obstruction is encountered while closing, the door will reverse.  
6. If an obstruction is encountered while opening, the door will stop.  
7. The optional Protector System™ uses an invisible beam which,  
when broken by an obstruction, causes a closing door to open and  
prevents an open door from closing. It is STRONGLY  
If Door Reverses During Down (Close) Cycle: Increase down  
(close) force by turning the control (2) in a clockwise direction. Make  
small adjustments until door completes close cycle. After each  
adjustment, run the opener through a complete travel cycle.  
RECOMMENDED for homeowners with young children.  
Allow a 15 minute cooling period after 5 continuous operations of  
the opener.  
Do not increase the force beyond the minimum amount required  
The opener light will turn on: 1. when opener is initially plugged in;  
to close the door.  
2. when the power is interrupted; 3. when the opener is activated.  
The light turns off automatically after 4-1/2 minutes. Bulb size is  
40 Watts maximum, ESRS type.  
23  
TEST THE SAFETY REVERSE SYSTEM –  
The safety reverse system test is important. Garage door must  
reverse on contact with a 25mm (1") obstacle laid flat on the  
floor. Failure to properly adjust opener may result in serious  
personal injury from a closing garage door. Repeat test once a  
month and adjust as needed.  
Procedure: Place a 25mm (1") obstacle (1) laid flat on the floor under  
the garage door. Operate the door in the down direction. The door  
must reverse on the obstruction. If the door stops on the obstruction,  
it is not traveling far enough in the down direction. Increase the down  
limit by turning down limit adjustment screw counterclockwise  
1/4 turn. Repeat test.  
CARE OF YOUR OPENER  
When properly installed, opener will provide high performance with  
a minimum of maintenance. The opener does not require additional  
lubrication.  
Limit and Force Adjustments: These adjustments must be checked  
and properly set when opener is installed. Only a screwdriver is  
required. Weather conditions may cause some minor changes in  
the door operation, requiring some re-adjustments, particularly  
during the first year of operation.  
When the door reverses on the 25mm (1") obstacle, remove the  
obstruction and run the opener through a complete travel cycle. Door  
must not reverse in closed position. If it does, adjust Limits and Force  
and repeat safety reverse test.  
Refer to the limit and force adjustments on pages 4 & 5. Follow the  
instructions carefully and repeat the safety reverse test after  
any adjustment.  
INSTALL THE PROTECTOR SYSTEM TM  
(See accessories)  
24  
Remote Control Transmitter: The portable remote control may be  
secured to a car sun visor with the clip provided. Additional remotes  
can be purchased at any time for use in all vehicles using garage.  
Refer to Accessories. The receiver must be programmed to operate  
with any new remote.  
The force, as measured on the closing edge of the door, should  
not exceed 150 N (15kg). If the closing force is adjusted to more  
than 150 N, the Protector System must be installed.  
Remote Control Battery: The 12 Volt battery should produce power  
for at least one year. When the light becomes dim or does not come  
on, replace the battery. If transmission range lessens, check the  
battery test light.  
After opener has been installed and adjusted, The Protector  
System™ accessory can be installed. Instructions are included with  
this accessory.  
The Protector System™ provides an additional measure of safety  
against a small child being caught under a garage door. It uses an  
invisible beam which, when broken by an obstruction, causes a closing  
door to open and prevents an open door from closing and is strongly  
recommended for homeowners with young children.  
To Change Battery: Remove visor clip and connecting screw in  
transmitter case. Snap connector onto new battery. Do not dispose of  
the old battery with household waste. Take batteries to a proper  
disposal center.

5. Opener noise is disturbing in living quarters of home:  
MAINTENANCE OF YOUR OPENER  
If operational noise is a problem because of proximity of the opener to  
the living quarters, Vibration Isolator Kit 41A3263 can be installed.  
This kit was designed to reduce the "sounding board effect" and is  
easy to install.  
Once a Month:  
Repeat safety reverse test. Make any necessary adjustments.  
Manually operate door. If it is unbalanced or binding, call for  
professional garage door service.  
Check to be sure door opens and closes fully. Adjust Limits  
and/or Force if necessary.  
6. The garage door opens and closes by itself:  
Make sure remote push button is not stuck "on".  
Twice a Year:  
Check chain tension. Disconnect trolley first. Adjust if necessary.  
Once a Year:  
7. Door stops but doesn't close completely:  
Review Travel Limits Adjustment.  
Oil door rollers, bearings and hinges. The opener does not require  
additional lubrication. Do not grease the door tracks.  
Repeat safety reverse test after any adjustment of door arm  
length, close force or down limit.  
8. Door opens but won't close:  
• Check The Protector System™ (if you have installed this accessory).  
If the light is blinking, correct alignment.  
• If opener light does not blink and it is a new installation, check the  
down force.  
Repeat the safety reverse test after the adjustment is complete.  
HAVING A PROBLEM?  
9. Opener light does not turn ON:  
1. Opener doesn't operate from remote control:  
Replace light bulb (40 Watts maximum). Replace burned out light  
bulbs with rough service light bulbs.  
• Does the opener have electric power? Plug lamp into outlet. If it  
doesn't light, check the fuse box or the circuit breaker. (Some outlets  
are controlled by a wall switch.)  
10. Opener light does not turn OFF:  
There may be a defective earth at the ceiling or wall receptacle.  
The unit must be earthed.  
• Have you disengaged all door locks? Review installation instruction  
warnings on page 1.  
• Is there a build-up of ice or snow under the door? The door may be  
frozen to ground. Remove any obstruction.  
11. Opener strains or maximum force is needed to activate door:  
Door may be unbalanced or springs are broken. Close door and use  
manual release rope and handle to disconnect trolley. Open and close  
door manually. A properly balanced door will stay in any point of travel  
while being supported entirely by its springs. If it does not, call for  
professional garage door service to correct the problem.  
• The garage door spring may be broken. Have it replaced.  
• Repeated operation may have tripped the overload protector in the  
motor. Wait 15 minutes. Try again.  
2. Remote has short range:  
Do not increase the force to operate the opener.  
• Is battery installed? Check battery test light. If the light is dim,  
change the battery.  
12. Opener motor hums briefly, then won't work:  
• Change the location of the remote control on the car.  
• Garage door springs are broken. SEE ABOVE.  
• A metal garage door, foil-backed insulation or metal siding will  
reduce the transmission range.  
• If problem occurs on first operation of opener, door is locked.  
Disable door lock. If chain was removed and reinstalled, the motor  
may be out of phase. Remove chain; cycle motor to down position.  
Observe drive sprocket. When it turns in clockwise direction and  
stops in down position, re-install chain.  
3. Door reverses for no apparent reason and opener light doesn't  
blink:  
Repeat safety reverse test after adjustment is complete.  
• Is something obstructing the door? Pull manual release handle.  
Operate door manually. If it is unbalanced or binding, call for  
professional garage door service.  
13. Opener won't activate due to power failure:  
• Clear any ice or snow from garage floor area where garage  
door closes.  
• Pull manual release rope and handle down and back to disconnect  
trolley. Door can be opened and closed manually. When the power is  
restored, pull the manual release handle straight down. The next  
time the opener is activated, the trolley will reconnect.  
• Review Force Adjustment.  
• If door reverses in FULLY CLOSED position, decrease travel limits.  
Repeat safety reverse test after adjustment is complete.  
• The Outside Quick Release accessory (if fitted) disconnects the  
trolley from outside the garage in case of power failure.  
The need for occasional adjustment of the force and limit  
settings is normal. Weather conditions in particular can affect  
door travel.  
14. The chain droops or sags:  
It is normal for the chain to droop slightly in the closed door position.  
Use the manual release rope and handle to disconnect the trolley. If  
the chain returns to the normal height when the trolley is disengaged  
and the door reverses on a 25mm (1") obstacle laid flat, no  
adjustments are needed.  
4. Door reverses for no apparent reason and opener light blinks  
for 5 seconds after reversing:  
Check The Protector System™ (if you have installed this accessory). If  
the light is blinking, correct alignment.
