COMPLETED INSTALLATION –

As you proceed with the assembly, installation and adjustment

proceedures in this manual, you may find it helpful to refer back

to this illustration of a completed installation.

FASTEN T-RAIL TO THE OPENER –

Place packing material under the opener to protect the opener cover.

For convenience, place a support under the cable pulley bracket end

of rail.

Remove the (2) washered screws (1) from the top of the opener. Align

holes in back end of the T-rail with holes in opener (2).

Fasten the rail to the opener with the same washered screws and

tighten securely. Caution: Use only those screws! Use of any other

screws will cause serious damage to the door opener.

Insert a hex screw (3) into trolley stop hole in T-rail (4). Tighten

securely with a lock washer (5) and nut (6).

INSTALL THE CHAIN/CABLE & ATTACH THE

SPROCKET COVER –

Do not remove chain/cable from carton.

Dispense a few inches of cable from carton and fasten to trolley with

a master link.

Master Link Procedure: Push pins of master link bar (5) through

cable loop (6) and hole in front end of trolley (7). Push cap (2) over

pins (8) and onto notches. Slide clip-on spring (1) over cap and onto

pin notches until both pins are securely locked in place.

Caution: Keep chain taut during installation to help prevent

kinking.

With the trolley against screwdriver, dispense chain/cable around

pulley (4). Proceed back around the opener sprocket (9). The opener

sprocket teeth must engage the chain. Continue forward to the trolley

threaded shaft.

Use the second master link to connect the chain to the flat end of the

threaded shaft (3).

Check to make sure the chain is not twisted.

Remove the screwdriver.

To attach the sprocket cover (10), insert the front tab (12) in the

opener slot. Using needle nose pliers, push together the two halves of

the back tab (11) inserting them on the mounting plate (13). Use

reverse procedure to remove.

TIGHTEN THE CHAIN/CABLE –

Spin inner nut (3) and lock washer (2) down threaded shaft (4).

Check to make sure chain is not twisted.

To tighten the chain, turn outer nut (1) in the direction shown. As you

turn the nut, keep the chain from twisting.

When chain is approximately 13mm (1/2") above the base of the

T-rail (5) at midpoint, re-tighten inner nut.

Sprocket noise can result if chain is either too loose or too tight.

When installation is complete, you may notice some chain droop with

the door closed. This is normal. If the chain returns to the position

described above when the door is open, do not re-adjust the chain.

During future maintenance, ALWAYS pull the manual release

handle to disconnect trolley before adjusting chain.

ASSEMBLY OF YOUR OPENER IS NOW COMPLETE.

ASSEMBLY SECTION –

105

Important: If you have a canopy or dual-track door, you need to

use the instructions packed with The Chamberlain Arm™

Accessory in conjunction with this Owner's Manual when

assembling the T-rail.

ASSEMBLE THE T-RAIL –

Place rail pieces on flat surface for assembly. The center sections with

tapered ends (5) are interchangeable. So are the end sections (4).

Connect the braces (3) and lock nuts (2) from one side of the rails and

insert the carriage bolts (6) from the opposite side. Then the trolley will

not hit the lock nuts when it is installed.

The square necks on the carriage bolts must be seated in square

holes in rail sections (1).

For canopy and dual-track doors, continue with the instructions

in this manual until Step 12.

INSTALL THE CABLE PULLEY BRACKET –

Position cable pulley bracket (2) on the front section of T-rail (6).

Fasten securely with: screws (1); lock washers (3) and nuts (4).

When tightening the screws, be sure to keep bracket parallel to

rail (5). Otherwise, rail may bow when opener is operated.

INSTALL THE TROLLEY –

Insert a screwdriver into trolley "stop" hole in the front end of T-rail (6).

Attach trolley threaded shaft (4) to the trolley with: lock washer (2),

and nuts (1 & 3). Slide trolley (5) along rail to the "stop".

Note: If the trolley hits any nuts on T-rail, review rail assembly

and reposition hardware.
