MODEL MD OPERATOR APPLICATIONS:
Drawbar operators are for commercial and industrial use on
sectional overhead doors which use horizontal track with
normal radius. A draw bar operator is not suitable for
doors with high lift exceeding 24 inches or vertical lift
doors. The installation requires a minimum clearance of 5
inches above the high arc of the door (the highest point
reached by the door at any part of its travel). Add 4 feet, 8
inches to the door height (4 feet, 2 inches for a 10 foot high
door) when measuring for the back-room required to install
the operator. When properly installed a drawbar operator
effectively locks the door in the closed position.
The Model MD (drawbar) operators are used in the
following applications:
-Limited Duty Commercial installations only
-Rate of operation shall not exceed 10 cycles of openings
and closings per hour, maximum of 75 cycles per day.
-Indoor Use Only
-Up to 14 foot high doors with a maximum area of
approximately 196 square feet (will vary depending on
door construction, consult factory)
- To operate in Momentary Contact To Close mode and
comply with the UL325 Entrapment Protection
requirements effective Aug. 29, 2010, the door system must
include one of the following (a, b, or c):
(a) Linear Corp. Photo-Beam System that consists of an
emitter, Part No. 217792 and detector, Part No. 217800 for
doors as described above up to 30 FT wide. See Page 10.
(b) Any Miller Edge ME, MT/MU, and CPT family of
edges, with suffix T2, must be connected to the SM-102
Edge Module, Recognized by UL as per UL325 2010 on 08
-29-2010 for door as described above. See Page 10.
(c) A Vitector Fraba OSE 2-wire Photosystem as
Recognized by UL as per UL325 2010 on 08-29-2010 for
door as described above. See Page 10.
The manufacturer of this operator strongly recommends
installation of one of the entrapment protection device
above and states that one is REQUIRED where any
automatic, remote or manual control is used to activate the
door.
OPTIONAL FEATURES:
Digital Radio Controls: Open, Close and Stop operation.
Radio units are available to control up to 27 doors from one
transmitter.
Timer to Close Operation: Two of the programmable
operation modes (T & TS), closing delay is adjustable from 5
seconds (factory set at 30 seconds) to 5 minutes in five

WARNING
ELECTRIC DOOR OPENERS ARE DESIGNED
FOR DOORS IN GOOD WORKING CONDITION,
PROPERLY COUNTERBALANCED AND
PROPERLY ADJUSTED IN ACCORDANCE WITH
THE DOOR MANUFACTURER'S INSTALLATION
INSTRUCTIONS.
Before starting the installation of the operator, the door must be in
good working condition and properly counterbalanced. Inspect
the door and track for loose or missing hardware. Test the door
manually for balance and ease of operation. Lubricate door hinges
and rollers. If necessary, adjust the springs for proper
counterbalance of the door.
Before removing the operator powerhead from the shipping
carton, inspect the nameplate on the cover of the operator control
box to verify that it is the correct model for the intended
application and that the voltage and phase are in accordance with
electrical power provided at the job site.
PREPARATION
The rails and drawbar chain/hardware package are shipped
separately from the powerhead.
Warning: Rope off the area to keep personnel and
vehicles clear of the door and floor space in the vicinity
of the operator during the installation.
WARNING
SPRINGS ARE SUBJECT TO VERY
HIGH FORCES AT ALL TIMES AND
ADJUSTMENTS MUST BE MADE ONLY
BY A QUALIFIED PROFESSIONAL
DOOR INSTALLER.

IMPORTANT INSTALLATION INSTRUCTIONS!
5
TO REDUCE THE RISK OF SEVERE
WARNING
INJURY OR DEATH:
READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS!
• Install only on a properly operating and balanced
garage door. A door that is operating improperly
could cause severe injury. Have qualified service
personnel make repairs to cables, spring
assemblies and other hardware before installing the
opener.
• Remove all pull ropes and remove, or make
inoperative, all locks (unless mechanically and/or
electrically interlocked to the power unit) that are
connected to the garage door before installing the
opener.
• Lightweight doors (fiberglass, aluminum etc.)
must be reinforced to avoid door damage. Check
the door manufacturer’s instruction manual for a
bracing procedure or the availability or a
Reinforcement Kit. See Page 9.
• Model MD is a Commercial Vehicular Door
Operator and as such IS NOT recommended for
pedestrian traffic. In installations where it is
known that pedestrians will be nearby ensure a
pedestrian door is available for entrance and exit to
the building. In addition YOU MUST install an
auxiliary entrapment protection device (reversing
door edge or photoelectric beam device).
• Connect an auxiliary entrapment protection
device (reversing edge or photoelectric device
across the door opening). A device of this type is
STRONGLY ADVISED FOR ALL commercial
operator installations. An auxiliary entrapment
protection device is REQUIRED when the three
button control station is out of sight of the door or
any other automatic or manual control is used.
• Install the door operator at least 8 feet or more
above the floor if the operator has exposed
moving parts.
• Do not connect the opener to the source of
power until instructed to do so.
• Locate the control station:
a) within sight of the door,
b) at a minimum height of five feet above the
floor so small children cannot reach it,
c) away from all moving parts of the door, and
d) far enough away from the door, or positioned
such that the user is prevented from coming in
contact with the door while operating the
controls.
Do not overtighten the clutch adjustment to
compensate for a poorly working door.
Install the Entrapment Warning Placard next to
the control station in a prominent location.
All warning signs and placards must be
installed so they are visible in the area of the door.
After installing the opener, all safety features
must be tested for proper operation (see page 20).
For products having a manual release, instruct
the end user on the operation of the manual
release.

RAIL/CHAIN ASSEMBLY
Refer to Figure 1 parts illustrations. The part names and
item numbers are referenced identically to the part
names and numbers in the assembly procedures
that follow. Before starting assembly of the
operator track check for the proper
length. The tracks are supplied for
8 Feet and 10/12/14 Feet high
doors. The tracks should
be three (3) feet
longer than the
door height. If the
tracks supplied
with the operator
are more than
three (3) feet
longer than the
door height it will
be necessary to
cut off two (2) feet
(or 4 feet for 10
FT doors) from
the power head mounting end as shown in Figure 2.
(48 INCHES FOR
10 FT DOORS
RAIL/CHAIN ASSEMBLY INSTRUCTIONS
107068
Figure 2
CAUTION: WHEN NECESSARY TO CUT THE TRACK ENSURE THE ENDS ARE LINED UP AS IN FIGURE 2.
1) Assemble the operator track by assembling the items as shown in Figure 2.
2) After the track is assembled, position track assembly onto the operator power head and attach with four 3/8”-16 x 1” bolts,
lock washers and nuts (supplied in a separate hardware package #100470).
3) Referring to Figure 1 , 2 and 3 (below) , slide the trolley onto the track with the chain take up bolt lug (C) toward the power
head. Thread one 3/8-16 keps nut (attached star washer) onto the Chain take up bolt with the keps part (attached star washer)
away from the chain attachment end. Insert the chain take up bolt threaded end through the lug hole on the trolley (C) just far
enough to start a second 3/8-16 keps nut. Attach one end of the chain to the opposite end of the threaded stud using a 3-piece
chain link (provided). See Figure 3.
4) Install chain around drive sprocket at operator head then around idler at front end of rail and thread through opening at fro nt
end of carrier. If the rail is equipped
with a chain guide-spacer near its
center (12 foot rail or longer only) pass
the chain over it in one direction and
under it in the other direction to
separate the two lengths of chain.
Apply initial tension by pushing
forward on the carrier while pulling
chain tight through opening in the
carrier in the direction of D. When
maximum tension has been applied by
this means, swing chain forward and
insert retaining plate, E, in place.
Insert 1/4-20 x 5/8 hex head machine
screw through retaining plate, E, and
tighten plate in place. Make final
adjustment of chain tension to remove
excess sag by adjusting nuts on
threaded rod at chain lug, C.
