Force Adjustment
- 23
Do not 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.
Force adjustment controls
(1&2) are located on the back
panel of operator. 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.
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.
Test down (close) force: Grasp the door handle or door
bottom when door is about half way 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 operator
through a complete cycle.
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 operator
through a complete travel cycle.
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 operator through a
complete travel cycle.
Do not increase the force beyond the minimum amount
required to close the door.
Test the Safety Reverse System
- 24
The safety reverse system test is important. Garage door
must reverse on contact with a 1” (25mm) obstacle laid flat
on the floor. Failure to properly adjust operator 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 travelling far enough in the
down
direction. Increase the
down limit by turning down limit adjust-
ment screw counterclockwise 1/4 turn.
Repeat test.
When the door reverses on the 25mm (1”) obstacle, remove
the obstruction and run the operator through a complete travel
cycle. Door
must not reverse in closed position. If it does, adjust
limits and force and repeat safety reverse test.
Install the Protector System
TM
(Optional)
- 25
After operator has been installed and adjusted,
The Protector
System
TM
accessory can be installed. Instructions are included
with this optional device.
The Protector System
TM
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 obstruc-
tion, causes a closing door to open and prevents and open
door from closing and is
strongly recommended for
homeowners with young children.
Activation of Your Operator
Your operator can be activated by any of the following devices:
•
The Lighted Door Control Button. Hold the button down until
door starts to move.
•
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.
Opening the Door Manually:
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 operator). To reconnect the door,
pull the release handle straight down. It will reconnect on the
next UP or DOWN operation.
Do not use the manual release handle to pull the door open
or closed.
When the Operator is Activated by Remote Control or Lighted
Door Control Button.
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.
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
TM
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
recommended for homeowners with young children.
Allow a 15 minute cooling period after 5 continuous activations
of the operator.
The operator light will turn on: 1. When operator is initially
plugged in; 2. When the power is interrupted; 3. When the
operator is activated.
The light turn off automatically after 4 1/2 minutes. Globe size
is 40 watts maximum.
Care of Your Operator
When properly installed, your operator will provide high
performance with a minimum of maintenance. The operator
does not require additional lubrication.
Limit and Force Adjustments: These adjustments must be
checked an properly set when operator is installed. Only a
screwdriver is required.
Weather conditions may cause some
minor changes in the door operation, requiring some
readjustments, particularly during the first year of
operation.
Refer to the limit and force adjustments on pages 4 & 5. Follow
the instructions carefully and
repeat the safety reverse test
after any adjustment.
Remote Control Transmitter: The portable remote control may
be secured a to a car sunvisor with the clip provided. Additional
remotes can be purchased at any time for use in all vehicles
using garage. Refer to accessories.
Remote Control Battery: Remove the battery compartment
cover, unsnap the connector and remove the old battery. Insert
a replacement battery. Snap connector onto new battery and
replace compartment cover. Do not dispose of the old battery
with household waste. Take battery to a proper disposal
centre.
