TO AVOID DAMAGE TO DOOR AND OPERATOR,
MAKE ALL DOOR LOCKS INOPERATIVE. SECURE
LOCK(S) IN "OPEN" POSITION.
IF THE DOOR LOCK NEEDS TO REMAIN FUNCTION-
AL, INSTALL AN INTERLOCK SWITCH.
DO NOT CONNECT ELECTRIC POWER UNTIL
INSTRUCTED TO DO SO.
KEEP DOOR BALANCED. STICKING OR BINDING
DOORS MUST BE REPAIRED. DOORS, DOOR
SPRINGS, CABLES, PULLEYS, BRACKETS AND
THEIR HARDWARE MAY BE UNDER EXTREME TEN-

SITE PREPARATIONS
It is imperative that the wall or mounting surface provide
adequate support for the operator.
This surface must:
a) Be rigid to prevent play between operator and
door shaft.
b) Provide a level base.
c) Permit the operator to be fastened securely and
with the drive shaft parallel to the door shaft.
The safety and wear of the operator will be adversely
affected if any of the above requirements are not met.
For metal buildings, fasten 2” x 2” x 3/16” (or larger) angle
iron frames to the building purlins. For proper spacing,
retain .2.75” between. See Figure 1.
IMPORTANT SAFETY NOTES

chain and set it aside.
Remove the two E Rings securing the sprocket on the
gear reducer shaft. Remove the screws securing the yoke
to the disconnect shaft, set the yoke aside.

1a.Wall Mounting
The operator should generally be installed below the door
shaft, and as close to the door as possible. The optimum
distance between the door shaft and operator drive shaft is
between 12” - 15”.Refer to Figure 3.
OPERATOR MOUNTING
IMPORTANT:The shelf or bracket must provide adequate
support, prevent play between operator and door shaft,
and permit operator to be fastened securely and with the
drive shaft parallel to the door shaft.
1b.Bracket or Shelf Mounting
The operator may be mounted either above or below the
door shaft. The optimum distance between the door shaft
and operator drive shaft is between 12” - 15”. Refer to
Figure 4.
1c.Place door sprocket on the door shaft. Do not insert the
key at this time.
2. Wrap drive chain around door sprocket and join roller
chain ends together with master link.
3.Raise operator to approximate mounting position and
position chain over operator sprocket.
4.Raise or lower operator until the chain is slightly taut
(not tight). Make sure the operator output shaft is paral-
lel to door shaft and sprockets are aligned. When in
position, secure the operator to wall or mounting brack-
et.
5.Align sprockets and secure, (see Figure 5).
FIGURE 4
FIGURE 3
Before your operator is installed, be sure the door has been properly aligned and is working smoothly. The operator may
be wall mounted or mounted on a bracket or shelf. If necessary, refer to the operator preparations on page 3. Refer to the
illustration and instructions below that suits your application.
Typical Left Hand
Wall Mounted Operator
Be sure door
sprocket is properly
aligned with drive
before securing to
the shaft.
Chain Keeper
FIGURE 5
Remove the three cotter pins from the disconnect shaft.
Do not discard the pins. Slide the disconnect shaft out of
the support bracket. The release lever will now be free
inside the motor frame. Remove the release lever and
sash chain from the motor frame. Slide the disconnect
hub, compression spring, and flatwasher from the end of
the gear reducer shaft. Remove the disconnect support
bracket by first removing the the two gear reducer hous-
ing screws. Replace the screws in the gear reducer and
firmly tighten.
2. Re-assemble Disconnect Assembly
Remove the two screws on the opposite side of the gear
reducer and mount the disconnect support bracket with
the notched side facing the motor. For the remainder of
the installation, follow the steps outlined above in reverse
order, referring to the illustration as necessary.

EMERGENCY MANUAL OPERATION
This operator has a floor level disconnect chain to dis-
connect the door from the door operator allowing for
manual operation of the door in case of emergency or
power failure.
1. To disengage, pull the chain and secure in the disen-
gaged position by slipping the end through the keyhole
bracket mounted on the wall. Or if emergency egress
device is used, pull handle to disengage operator from
door.
2. The door may now be pushed up or pulled down
manually. Release the disconnect chain to operate the
door again electrically.
Keyhole Bracket
6. Mount Chain Keeper / Keyhole Bracket
Using suitable hardware mount the chain keeper
approximately 4 feet above the floor, near the free
hanging chain. Remove disconnect sash chain from
bag and place the end through the keyhole in the the
chain keeper. Remove excess links if necessary.
TURN OFF POWER TO THE OPERATOR BEFORE
MANUALLY OPERATING YOUR DOOR.

WARNING
LIMIT SWITCH ADJUSTMENT
MAKE SURE THE LIMIT NUTS ARE POSITIONED BETWEEN THE LIMIT SWITCH ACTUATORS BEFORE PRO-
CEEDING WITH ADJUSTMENTS.
ELECTRIC SENSING EDGES
Electric sensing edges with an isolated normally open
(N.O.) output are compatible with your operator. If your
door does not have a bottom sensing edge and you wish
to purchase one, contact the supplier of your operator.
If not pre-installed by the door manufacturer, mount the
sensing edge on the door according to the instructions
provided with the edge. The sensing edge may be elec-
trically connected by either coiled cord or take-up reel.
Refer to the steps below
Important Notes:
a) Proceed with Limit Switch Adjustments before mak-
ing any sensing edge wiring connections to operator
as described below.
b) Electrician must hardwire the junction box to the
operator electrical box in accordance with local
codes.
ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL)
TAKE-UP REEL: Take-up reel should be installed 12"
above the top of the door.
COIL CORD: Connect operator end of coil cord to junc-
tion box (not supplied) fastened to the wall approximate-
ly halfway up the door opening.

to spin freely. After adjustment, release plate and
ensure it seats fully in slots of both nuts.
2. To increase door travel, spin nut away from actuator.
To decrease door travel, spin limit nut toward actua-
tor.
3. Adjust open limit nut so that door will stop in open
position with the bottom of the door even with top of
door opening.
4. Repeat Steps 1 and 2 for close cycle. Adjust close

CONTROL WIRING
Standard C2 or B2 Wiring
Model MGJ operators are shipped from the factory with
jumper set for C2 wiring, which requires constant pres-
sure on button to close the door. If momentary contact
on close direction is desired (B2 wiring) you must include
an entrapment protection device. See close control
jumper setting below.
Constant pressure on close (C2 wiring)
Red jumper wire was placed on terminal #2 in the elec-
trical enclosure. The operator will require constant pres-
sure on close control in order to keep door moving in the
close direction.
Momentary contact on close (B2 wiring)
Move red jumper wire from terminal #2 to terminal #3.
The operator will require only momentary contact to
close the door.
LOCATING THE CONTROL STATION
All operators are supplied with some type of control station. Generally a three button station (OPEN/CLOSE/STOP) is pro-
vided.A two-position key switch or control station (OPEN/CLOSE) may be added or substituted when requested at the time
of order. Mount the control station near the door.
WARNING
CAUTION
WARNING
WARNING
INSTALL THE CONTROL STATION WHERE THE DOOR
IS VISIBLE, BUT AWAY FROM THE DOOR AND ITS
HARDWARE. IF CONTROL STATION CANNOT BE
INSTALLED WHERE DOOR IS VISIBLE, OR IF ANY
DEVICE OTHER THAN THE CONTROL STATION IS
USEDTO ACTIVATETHE DOOR,
A REVERSING EDGE
MUST BE INSTALLED ON THE BOTTOM OF THE
DOOR.
FAILURE TO INSTALL A REVERSING EDGE
UNDER THESE CIRCUMSTANCES MAY RESULT IN
SERIOUS INJURY OR DEATH TO PERSONS
