PREPARING YOUR GARAGE DOOR

To prevent possible SERIOUSINJURYor DEATH:

• ALWAYS call a trained door systems technician if garage door binds, sticks, or

is out of balance. An unbalanced garage door may NOT reverse when required.

• NEVER try to loosen, move or adjust garage door, door springs, cables,

pulleys, brackets or their hardware, ALLof which are under EXTREME tension.

• Disable ALLlocks and remove ALLropes connected to garage door BEFORE

installation and operating garage door opener to avoid entanglement.

• DO NOT install on a one-piece door if using devices or features providing

unattended close. Unattended devices and features are to be used ONLY with

sectional doors.

To prevent damage to garage door and opener:

• ALWAYS disable locks BEFORE installing and operating the opener.

• ONLY operate garage door opener at 120V, 60Hz to avoid malfunction and

damage.

Before you begin:

1. Disable locks and remove any ropes connected to the garage door.

2. Lift the door halfway up. Release the door. If balanced, it should stay in

place, supported entirely by its springs.

3. Raise and lower the door to check for binding or sticking. If your door binds,

sticks, or is out of balance, call a trained door systems technician.

4. Check the seal on the bottom of the door. Any gap between the floor and the

bottom of the door must not exceed 1/4" (6mm). Otherwise, the safety

reversal system may not work properly.

5. The opener should be installed above the center of the door. If there is a

torsion spring or center bearing plate in the way of the header bracket, it

may be installed within 4feet (1.2 m) to the left or right of the door center.

PLANNING

Identify the type and height of your garage door. Survey your garage area to see if any

of the conditions below apply to your installation. Additional materials may be

required. You may find it helpful to refer back to this page and the accompanying

illustrations as you proceed with the installation of your opener. Depending on your

requirements, there are several installation steps which may call for materials or

hardware not included in the carton.

• Installation Step 1 – Look at the wall or ceiling above the garage door. The

header bracket must be securely fastened to structural supports.

• Installation Step 5 – Do you have a finished ceiling in your garage? If so, a

support bracket and additional fastening hardware may be required.

• Installation Step 12 – Depending upon garage construction, extension

brackets or wood blocks may be needed to install sensors.

• Installation Step 12 – Alternate floor mounting of the safety reversing

sensor will require hardware not provided.

• Do you have an access door in addition to the garage door? If not, an

emergency key release is required.

• Look at the garage door where it meets the floor. Any gap between the floor

and the bottom of the door must not exceed 1/4" (6 mm). Otherwise, the

safety reversal system may not work properly. See Adjustment Step 2. Floor

or door should be repaired.

SECTIONAL DOOR INSTALLATION

• Do you have a steel, aluminum, fiberglass or glass panel door? If so,

horizontal and vertical reinforcement is required (Installation Step 8).

• The opener should be installed above the center of the door. If there is a

torsion spring or center bearing plate in the way of the header bracket, it

may be installed within 4 feet (1.22 m) to the left or right of the door

center. See Installation Steps 1 and 8.

• If your door is more than 7 feet (2.13 m) high, see rail extension kits listed

on Accessories page.

INSTALLATION STEP 1

DETERMINE THE HEADER BRACKET LOCATION

To prevent possible SERIOUS INJURY or DEATH:

• Header bracket MUST be RIGIDLY fastened to structural support on header

wall or ceiling, otherwise garage door might NOT reverse when required. DO

NOT install header bracket over drywall.

• Concrete anchors MUST be used if mounting header bracket or 2x4 into

masonry.

• NEVER try to loosen, move or adjust garage door, springs, cables, pulleys,

brackets, or their hardware, ALL of which are under EXTREME tension.

• ALWAYS call a trained door systems technician if garage door binds, sticks,

or is out of balance. An unbalanced garage door might NOT reverse when

required.

Installation procedures vary according to garage door types. Follow the instructions

which apply to your door.

1. Close the door and mark the inside vertical centerline of the garage door.

2. Extend the line onto the header wall above the door. You can fasten the

header bracket within 4 feet (1.22 m) of the left or right of the door center

only if a torsion spring or center bearing plate is in the way; or you can

attach it to the ceiling (see page 14) when clearance is minimal. (It may be

mounted on the wall upside down if necessary, to gain approximately 1/2"

(1 cm). If you need to install the header bracket on a 2x4 (on wall or ceiling),

use lag screws (not provided) to securely fasten the 2x4 to structural

supports as shown here and on page 14.

3. Open your door to the highest point of travel as shown. Draw an intersecting

horizontal line on the header wall above the high point:

• 2" (5 cm) above the high point for sectional door and one-piece door with

track.

• 8" (20 cm) above the high point for one-piece door without track.

This height will provide travel clearance for the top edge of the door.

NOTE: If the total number of inches exceeds the height available in your garage, use

the maximum height possible, or refer to page14 for ceiling installation.

INSTALLATION STEP 5

HANG THE OPENER

To avoid possible SERIOUS INJURY from a falling garage door opener, fasten it

SECURELY to structural supports of the garage. Concrete anchors MUST be used

if installing ANY brackets into masonry.

Three representative installations are shown. Yours may be different. Hanging

brackets should be angled (Figure 1) to provide rigid support. On finished ceilings

(Figures 2 and 3), attach a sturdy metal bracket to structural supports before

installing the opener. This bracket and fastening hardware are not provided.

1. Measure the distance from each side of the motor unit to the structural

support.

2. Cut both pieces of the hanging bracket to required lengths.

3. Drill 3/16" pilot holes in the structural supports.

4. Attach one end of each bracket to a support with 5/16"-9x1-5/8" lag screws.

5. Fasten the opener to the hanging brackets with 5/16"-18x7/8" hex bolts,

lock washers and nuts.

6. Check to make sure the rail is centered over the door (or in line with the

header bracket if the bracket is not centered above the door).

7. Remove the 2x4. Operate the door manually. If the door hits the rail, raise

the header bracket.

NOTE: DO NOT connect power to opener at this time.

INSTALL THE LIGHTS

To prevent possible OVERHEATING of the end panel or light socket:

• Use ONLY A19 light bulbs.

• DO NOT use incandescent bulbs larger than 100W.

• DO NOT use compact fluorescent light bulbs larger than 26W (100W

equivalent).

• DO NOT use halogen bulbs.

• DO NOT use short neck or specialty light bulbs.

LED bulbs may cause remote control radio interference. Visit craftsman.com for

a list of recommended LED bulbs.

1. Pull light lens down.

2. Insert light bulb.

3. Close light lens.

INSTALLATION STEP 7

ATTACH THE EMERGENCY RELEASE ROPE AND HANDLE

To prevent possible SERIOUS INJURY or DEATH from a falling garage door:

• If possible, use emergency release handle to disengage trolley ONLY when

garage door is CLOSED. Weak or broken springs or unbalanced door could

result in an open door falling rapidly and/or unexpectedly.

• NEVER use emergency release handle unless garage doorway is clear of

persons and obstructions.

• NEVER use handle to pull door open or closed. If rope knot becomes untied,

you could fall.

1. Insert one end of the emergency release rope through the handle. Make sure

that “NOTICE” is right side up. Secure with an overhand knot at least 1" (2.5

cm) from the end of the rope to prevent slipping.

2. Insert the other end of the emergency release rope through the hole in the

trolley release arm. Mount the emergency release within reach, but at least 6

feet (1.83m) above floor, avoiding contact with vehicles to prevent

accidental release and secure with an overhand knot.

NOTE: If it is necessary to cut the emergency release rope, seal the cut end with a

match or lighter to prevent unraveling. Ensure the emergency release rope and handle

are above the top of all vehicles to avoid entanglement.

INSTALLATION STEP 8

FASTEN THE DOOR BRACKET

Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE

reinforcement BEFORE installation of door bracket. Contact the garage door

manufacturer or installing dealer for opener reinforcement instructions or

reinforcement kit.

Follow instructions which apply to your door type as illustrated below or on the

following page.

A horizontal reinforcement brace should be long enough to be secured to two or

three vertical supports. A vertical reinforcement brace should cover the height of

the top panel.

Figure 1 shows one piece of angle iron as the horizontal brace. For the vertical

brace, 2 pieces of angle iron are used to create a U-shaped support. The best

solution is to check with your garage door manufacturer for an opener installation

door reinforcement kit.

NOTE: Many door reinforcement kits provide for direct attachment of the clevis pin

and door arm. In this case you will not need the door bracket; proceed to Step 9.

SECTIONAL DOORS

1. Center the door bracket on the previously marked vertical centerline used

for the header bracket installation. Note correct UP placement, as stamped

inside the bracket.

2. Position the top edge of the bracket 2"-4" (5-10cm) below the top edge of

the door, OR directly below any structural support across the top of the

door.

3. Mark, drill holes and install as follows, depending on your door’s

construction.

Metal or light weight doors using a vertical angle iron brace between the door panel

support and the door bracket:

• Drill 3/16" fastening holes. Secure the door bracket using the two 1/4"-

14x5/8" self-threading screws. (Figure2A)

• Alternately, use two 5/16"-18x2" bolts, lock washers and nuts (not

provided). (Figure2B)

Metal, insulated or light weight factory reinforced doors:

• Drill 3/16" fastening holes. Secure the door bracket using the self-threading

screws. (Figure3)

Wood doors:

• Use top and bottom or side to side door bracket holes. Drill 5/16" holes

through the door and secure bracket with 5/16"-18x2" carriage bolts, lock

washers and nuts (not provided). (Figure4)

NOTE: The 1/4"-14x5/8" self-threading screws are not intended for use on wood

doors.
