Care of the Opener
When properly installed on a door which is in balance
and in good repair, opener will provide high
performance with a minimum of maintenance. The
opener does not require additional lubrication.
Most complaints of unsatisfactory opener operation
can be traced to problems with the door itself. When
operated manually, a properly balanced door will stay
in any point of travel while being supported entirely by
its springs.
THE OPENER IS NOT INTENDED TO CORRECT
ANY PROBLEMS THAT ARE CAUSED BY AN
UNBALANCED OR BINDING DOOR, BROKEN
DOOR SPRINGS OR BY FAULTY DOOR
HARDWARE.
LIMIT AND FORCE ADJUSTMENTS: These
adjustments must be checked and properly set when
opener is installed. Only a screwdriver is required.
Pages 20 and 21 refer to the limit and force
adjustments. Follow the instructions carefully.
REPEAT THE SAFETY REVERSE TEST AFTER
ANY ADJUSTMENT. Weather conditions may cause
some minor changes in the door operation, requiring
some readjustments, particularly during the first year
of operation.
THE SAFETY REVERSE SYSTEM IS IMPORTANT
(see page 22). GARAGE DOOR MUST REVERSE
ON CONTACT WITH A 25MM OBSTACLE PLACED
ON THE FLOOR. FAILURE TO PROPERLY
ADJUST OPENER MAY RESULT IN SERIOUS
PERSONAL INJURY FROM A CLOSING GARAGE
DOOR.
CHAIN TENSION ADJUSTMENT: After installation
of the opener and adjustment of forces and limits, the
chain may appear loose. This is normal.
TO CHECK THE CHAIN TENSION: Disconnect the
trolley by pulling the red manual release handle. If the
chain returns to the position described and illustrated
in Step 4 page 9, DO NOT make ANY further
adjustments.
REMOTE CONTROL TRANSMITTER: The portable
remote control may be secured to a car sun visor with
the clip provided. Additional remote transmitters can
be purchased at any time for use in all vehicles using
the garage. Refer to Accessories on page 5.
The opener must learn the code of any new remote
control. Page 23 explains how to program your
garage door opener and how to erase all codes if
required. Self service of your receiver and remote
control is not recommended. If service is needed, call
the toll-free number listed on the back page.
THE REMOTE CONTROL BATTERY
The lithium battery should produce power for up to
5 years. To replace battery, pry open case with visor
clip or screwdriver, as shown. Insert battery positive
side up.
Dispose of old battery properly.
ONCE A MONTH
MANUALLY OPERATE DOOR. If it is unbalanced or
binding, call professional garage door service.
CHECK TO BE SURE DOOR OPENS AND
CLOSES FULLY. Adjusts Limits and/or Force if
necessary.

PROCEDURE: Raise the opener onto a stepladder.
Open garage door. Place a 25mm board on the top
section of door near centerline as shown. Rest T-rail
on 25mm board as shown.
PROCEDURE: Measure the distance from floor to top of
door (in fully open position and parallel to the floor). Using a
stepladder as a support, raise opener to the same distance
from the floor (it will have a slight angle as shown).
The top of the door should be level with the top of
opener. For maximum efficiency, do not position opener
more than 5cm above this point.

Two representative installations are shown. Yours may be different. Hanging brackets should be angled (Figure 1)
to provide rigid support. On finished ceilings (Figure 2) attach a sturdy metal bracket (not supplied) to structural supports
before installing opener.
PROCEDURE: Measure the distance from EACH side
of the opener to structural support.
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
brackets holes. Drill 5mm pilot holes in the structural
supports. Attach flattened ends of brackets to
suppports with 5/16"x1-7/8" lag screws.
Lift opener and fasten to hanging bracket as shown.
Check to make sure T-rail is centered over door.

OPEN DOOR ADJUSTMENT
Decrease UP limit. Turn UP limit adjustment screw
counterclockwise 5-1/2 turns.
Press door control button. Trolley will travel to full
open position.
Manually raise door arm to open position (parallel to
floor) and lift door arm to trolley. The arm should
touch trolley just in back of door arm connector hole
as shown in solid line drawing. If arm does not
extend far enough, adjust limit further. One full turn
equals 5cm of door travel.
CLOSED DOOR ADJUSTMENT
Decrease DOWN limit. Turn DOWN limit adjustment
screw clockwise 5 complete turns.
Press door control button. Trolley will travel to full
closed position.
Manually close door and lift door arm to trolley. The
arm should touch trolley just ahead of door arm
connector hole as shown in dotted line drawing. If
arm is behind the connector hole, adjust limit further.
One full turn equals 5cm of door travel.
CONNECT DOOR ARM TO TROLLEY: With door closed, join curved arm to connector hole in trolley with
remaining clevis pin. Secure with ring fastener. NOTE: It may be necessary to lift door slightly to make
connection.
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.
19
13mm Socket Wrench
Before connecting door arm to trolley, limits of travel must be adjusted on one-piece doors. Limit adjustment
screws are located on left side panel as shown in illustration on page 20. Follow procedures below.

Adjustment Step 1
Adjust UP and DOWN Limits
LIMIT ADJUSTMENT settings regulate the points at
which the door will stop when moving up or down.
NOTE: Door STOPS in the UP direction if
anything interferes with door travel. Door
REVERSES in the DOWN direction if anything
interferes with the door travel (including binding
or unbalanced doors).
PROCEDURE: To operate the opener, press the
Door Control Button or transmitter. Run the opener
through a COMPLETE TRAVEL CYCLE. No limit
adjustments are necessary when the door opens
and closes completely and doesn’t reverse
unintentionally when fully closed.
The following chart outlines adjustments procedures. RUN THE OPENER THROUGH A COMPLETE TRAVEL
CYCLE AFTER AFTER EACH ADJUSTMENT.
NOTE: REPEATED OPERATION OF THE OPENER DURING ADJUSTMENT PROCEDURES MAY CAUSE
MOTOR TO OVERHEAT AND SHUT OFF. SIMPLY WAIT 15 MINUTES AND TRY AGAIN.
Read the chart carefully before proceeding to Step 2. Use a screwdriver to make limit adjustments.
IF DOOR DOES NOT OPEN COMPLETELY
BUT OPENS AT LEAST 1.5M
Increase UP travel. Turn the UP LIMIT adjustment
screw clockwise. One turn equals 5cm of travel.
If door does not open at least 1.5m: Adjust UP
(OPEN) FORCE as explained in step 2.
IF DOOR DOES NOT CLOSE COMPLETELY
Increase DOWN travel. Turn down limit adjustment
screw counterclockwise. One turn equals 5cm of
travel.
If the door still will not close completely, the header
bracket is positioned too high. See Step 1, page 10.
IF OPENER REVERSES
IN FULLY CLOSED POSITION
Decrease DOWN travel. Turn down limit adjustment
screw clockwise. One turn equals 5cm 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 for garage door service. If door is not
binding or unbalanced, adjust DOWN (CLOSE)
FORCE. See Step 2.
