PREPARATION
Correct all “High Risk” areas on the garage door
before installation of the new Martin Torsion Drive
Opener. If unable to correct, replace garage door with
a new Martin Garage Door. See Back Page
Decide if the Motor Assembly will be mounted to the
right side or left side of the garage door.
The Torsion Tube/Shaft protrudes 5”(130) beyond the
lock-on/side bearing bracket. (Motor Assembly side
clearance requires an extra 4.5”(114) beyond the end
of the tube/shaft.) See Figure 12, 13
A qualified electrician should install a grounded
electrical outlet within 5’(1520) of the Control Box
Assembly location according to local codes.
See Figure 1
Make sure the garage door is properly balanced, the
moving steel parts properly lubricated, and the jambs
waxed where the garage door rubs. The door should
work free and easy as it opens and closes. Please call
a trained Martin Dealer if you have a problem or do not
understand.
The garage door should be at least 5’(1520) high.

Untrained or Negligent Installing, Adjusting and Servicing can be Dangerous! The
garage door springs and related parts can cause serious injury or death! IF YOUARE
UNSURE,CALLATRAINEDMARTINDOORDEALER!
Garagedoorshouldbebalancedandeasytoopenandclosebyhand.
Locksshouldbedisabledandpulldownropesshouldberemoved.
Locate the control box/push button within sight of door, at min. height of 5' (1520) so
small children cannot reach it, and away from all moving parts of door.
Emergency release lever should be installed and adjusted to about 6' (1830) above
the floor. Monthly check that the lever angle is correct. See page 4, 9
Risk of electrical shock is explained in Step 3. Do not connect opener to source of
power until instructed to do so.
Entrapment and warning labels should be installed next to the control box/push
button.
Where possible install opener 7’(2135) or more above the floor.
IMPORTANT
MAINTENANCE & SAFETY INSTRUCTIONS
Monthly, check the opener's down cycle safety reverse. The door must reverse when it contacts
a 1 1/2" (38) high object (or a 2X4 board laid flat) on the floor. Aclosing door must also reverse
if the optional photo eyes are interrupted.
Always keep the moving door in sight and away from people and objects until it is
completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
NEVER GO UNDER A STOPPED, PARTIALLY OPEN DOOR
Do not allow children to operate or play with the garage door opener controls. Keep all
remote control transmitters away from children.
The emergency release should only be used when garage door is in the closed position.
Weak or broken springs may cause door to fall if released in the open position, increasing
the risk of severe injury or death. Use caution when using the release with door open.
Monthly visually check the lift cables, spring assembly, hardware, etc. for wear and stability.
If the Safety Reverse or any other part of the garage door and opener system do not work
properly, or if you do not understand, call a trained Martin Door Dealer.

STEP 2
INSTALLING THE EMERGENCY RELEASE ASSEMBLY
Fasten the cable post which is fastened to the outer sheath of the bowden cable
to the vertical track or track bracket, etc., with the two flat head 7/32" (5) screws
and nuts provided. (If fastened to the jamb, use optional 2 1/2”(64) long hex head
lag screws.) Allow at least 2" (51) slack to the outer sheath of the bowden cable.
Mark and drill two 7/32" (5) holes. See Figures 6a to 7b, 21
Place screw hook in D-shackle at end of bowden cable or at the end of the
extension chain. See Figures 8a to 9b, 21
The Emergency Release Lever should be about 5’ - 6' (1830) above the floor. If
the Bowden cable is not long enough, a short piece of chain (optional) should be
used.
Mark and drill two 7/32” (5) holes in the vertical track or track bracket, etc., with
the emergency release lever at an 85° angle, never less than 90°. Fasten
emergency release lever with mounting bracket using two 7/32” (5) flat head
screws and nuts provided. See Figures 8a to 9b, 20a, 20b, 21
The Bowden Cable should be taut when the emergency release lever is at an 85°
angle. Adjust the screw hook as necessary, then tighten the lock nut. Push the
emergency release lever down. Drill new holes and remount if required.
When the emergency release lever (RED) is pushed down, the drive belt
tensioning plate moves, tightening the drive belt on the motor and torsion shaft
pulley. The garage door opener will not function without proper drive belt
tension. The computer cannot learn if drive belt slips. Pushing the
emergency release lever up or down, disconnects or connects the garage door
opener to the garage door. The garage door should be closed when
connecting or disconnecting the Emergency Release Lever. Following a
power outage etc, disconnect the power from the control box for 30
seconds. After reconnecting the power, open and close garage door two or
more complete cycles (door may run slow). The computer should restore the
original open and close positions without a calibration reset. See Step 4 for
calibration reset
Note: The emergency release lever is first set at an 85° angle before
engaging, because the chain, cable, belt, etc. will slightly stretch
during the first few cycles. NEVER ALLOW THE EMERGENCY
RELEASE LEVER TO BE MORE THAN 90° WHEN DISENGAGED
WITH THE BOWDEN CABLE TAUT. CHECK DRIVE BELT FOR
PROPER TENSION AFTER ONE MONTH OF USE.

STEP 3
INSTALLING THE CONTROL BOX ASSEMBLY
Fasten the control box to the wall about 5' (1520) from the ground with screws.
The holes are in the corner pillars, which are outside the water resistant gasket of
the control box. See Figures 1, 24 Because the push button is mounted in the
control box lid, the control box should be mounted within sight of the garage door,
clear of all moving garage door parts.
ATTENTION! The control box is water resistant. Do not drill holes in the control
box! Route all wires through the conduit outlets at the bottom of the control
box. Dress wiring tight and straight, using ties, staples or other means.
See Figures 23, 24
Temporarily fasten the control box lid to the left or right side, above or below the
control box to prevent it from hanging by the push button wires during the setup
process. See Figures 23, 24 The push button should only be used when the
garage door area is free of people or any obstructions.
Plug the three wire low voltage DC motor wiring harness, if not plugged in, into the
terminal block at the bottom right hand side of the circuit board that is marked "DC
Motor". See Figures 10b, 26a, 26b. Plug the opposite end into the three way
terminal in the motor assembly. See Figures 2b, 27. Do not cut or shorten excess
wiring. Coil excess wire and tie away from moving parts.
See Figure 28

***STEP 3 CONTINUED***
The control box assembly includes a 6’(1800) power cord with a
three prong plug. The third prong is ground. To reduce the risk of
electric shock do not alter or change plug or outlet in any way. Do not
try to conceal or staple the power cord or try to rout it through a door
way, window, wall, ceiling, floor, etc. The power cord must be routed
away from moving parts.
Also see “WARNING” On page 12.
Wait until Step 4 before plugging the power cord into the grounded
electrical outlet.
DO NOT PINCH WIRING! The door opener will not work properly
with damaged wiring.

TESTING THE GARAGE DOOR OPENER SYSTEM
Press the push button to open door. Observe that LED #5
OPNG illuminates as the garage door opens. The garage door
will stop when it reaches the full open position allowed by the
cable drums or optional bumper springs. Press the push button to
close the door. Observe that LED #4 CLSNG illuminates as the
garage door closes. The garage door will stop when it reaches
the floor. If OPNG or CLSNG light does not go out when door
stops, the belt tension may need to be adjusted (Max Power and
Close Sensitivity may also need adjusting). See Figure 43
Open and close garage door two more complete cycles.
Observe the movement of the garage door as the computer
memorizes the open and close position. You may notice that
LED #1 ACK illuminates from time to time. The garage door
opener system now provides “soft start” and “soft stop” as the
door opens and closes. See Figure 43
Do Not touch the following settings unless you are sure.
Force Setting: MAX POWER is factory set at one o’clock. Force
can be slightly increased by turning screw clockwise 10 degrees
at a time. See Figure 10b, 43
Sensitivity Setting: CLOSE SENSITIVITY is factory set at one
o’clock. Sensitivity can be increased by turning screw clockwise
10 degrees at a time. See Figure 10b, 43
Place a 1 1/2”(38) high object (or a 2X4 laid flat) on the floor,
under the door. When the closing door contacts the object, it
should stop, reverse, and automatically return to the open
position. See Figure 44
If the door does not reverse, the drive belt may be slipping. After
correcting drive belt tension and the door still does not reverse,
call a trained Martin Door dealer. See Step 2
STEP 7
INSERT INSTRUCTION MANUAL INTO PACKET
Fold and Insert instruction manual into the packet located on the
#3 door section of the Martin garage door or mount to the wall.
An Important safety/instruction label is included with opener
package. This label and the instruction manual must be fastened
inside your garage where they can be easily seen. Fasten them
next to the wall control box. Peel off the protective backing, and
press onto smooth, clean surface. Tacks or additional adhesive
may be necessary. DO NOT REMOVE OR PAINT OVERANY
LABELS. See Figures 45, 46

IMPORTANT MAINTENANCE & SAFETY INSTRUCTIONS
Monthly, check the opener's down cycle safety reverse. The door must reverse when it
contacts a 1 1/2" (38) high object (or a 2X4 board laid flat) on the floor. Aclosing door must
also reverse if the optional photo eyes are interrupted.
Always keep the moving door in sight and away from people and objects until it is
completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
NEVER go under a stopped, partially open door.
Do not allow children to operate or play with the garage door controls. Keep the remote
control away from children.
SAVE THESE IMPORTANT INSTRUCTIONS
If the Safety Reverse or any other part of the garage door and opener system do not work
properly, or if you do not understand, call a trained Martin Door Dealer.
The emergency release should only be used when garage door is in the closed position.
Weak or broken springs may cause door to fall, if released in the open position, increasing
the risk of severe injury or death. Use caution when using the release with door open.
Monthly visually check lift cables, spring assembly, hardware, etc. for wear and stability.
KEEP GARAGE DOOR PROPERLY BALANCED. See garage door owner’s manual. An
improperly balanced door increases the risk of severe injury or death. Call a trained Martin
Door Dealer to repair lift cables, spring assemblies and other hardware.
!
TO REDUCE THE RISK OF SEVERE INJURY OR
DEATH, READ AND FOLLOW ALL INSTRUCTIONS
STEP 8
INSTALLING THE FRONT MOTOR COVER (OPTIONAL)
The front cover has two motor barrel clips, which fasten over the motor
barrel. Position the front cover with the clips touching the motor barrel,
then with a hand over the clip area, firmly push the front cover until the
clips fasten to the motor barrel. Fit the two pegs
located in the top edge of the back cover into the
two holes located in the top edge of the
front cover. Fasten front and back
cover together with the small
screws into the small clips.
See Figures 2a, 2b, 47
FIGURE 47
INTERLOCK CIRCUIT WIRING
A pair of “Interlock” terminals is provided for a pass door switch or a key switch
(lock-out switch) to be interlocked to the opener, to prevent the garage door from
opening if the “Interlock” terminals are open circuit.
See Figure 10b, 48a
Interlock O/RIDE, DIP switch No. 5 is normally set to ON. If you want to add an
interlock device, move switch No. 5 to OFF. See Figure 10b, 48b
A slide lock switch may be installed and connected into the interlock terminals.
However this may not be necessary because the opener will detect the obstruction
and stop the garage door if the slide lock is left in the lock position.
