IMPORTANT NOTE: Before the operator is installed, be sure the door has been properly aligned and is working
smoothly. Although each installation will vary due to particular building characteristics, refer to the following gen-
eral procedures to install the operator.

The trolley operator is generally mounted over the
center of the door. However, off center mounting may
be required due to interfering structures or location of
door stile / top section support. In such cases, the
operator may be mounted up to 24” off center on tor-
sion spring doors.
Extension springs require center
mounting.
1.
Locate the center of the door and mark a line on
the wall directly above the door. Extend this line up
the wall.
2.
Determine the highest point of door travel. Slowly
raise the door and observe the action of the top sec-
tion. When the top section reaches its highest point,
use a level and project a line from this point to the
center line the of the door.
MOUNT OPERATOR
1.
Allowing the motor to rest on the floor, raise the
front end of the track assembly to the front header
bracket and fasten using the 3/8”dia. x 6.40” long pivot
shaft and cotterpins supplied.
3.
Using the projected lines for location, mount a
suitable wood block or length of angle iron to the wall
above the door opening.
Refer to the illustration
below. This will provide a mounting pad for the front
header bracket of the operator. If necessary reinforce
the wall with suitable mounting brackets to ensure
adequate support of mounting pad.
Using suitable
hardware, mount the (U shaped) front header bracket
to the pad.

2.
Swing the operator to a horizontal position above
the guide rails and temporarily secure with a suitable
rope, chain, or support from the floor.
Now open
garage door slowly, being careful not to dislodge the
temporary support.
Using the door as a support,
place a level against the rail and shim the operator
until it is horizontal. Make sure that the operator is
aligned with the center line of the door.
