Instructions – Garage Door Operator – Model MotorLift 2000UK

The force, as measured on the closing edge of the door, should not exceed 150 N (15kg). If the closing force is adjusted to more than 150 N, the Protector System must be installed. Do not use the force adjustments to compensate for a binding or sticking garage door.

Excessive force will interfere with the proper operation of the Safety Reverse System or damage the garage door.

Fasten the caution label adjacent to the lighted door control button as a reminder of safe operating procedures.

Disengage all existing garage door locks

to avoid

damage to garage door. Install the lighted door control button (or any additional push

buttons)

in a location where the garage door is visible, but out of the reach of children. Do not allow children to operate push button(s) or remote control(s).

Serious personal injury from a closing garage door may result from misuse of the opener.

Activate opener only when the door is in full view, free of obstructions and opener is properly adjusted. No one should enter or leave the garage while the door is in motion. Do not allow children to play near the door.

Use manual release only to disengage the trolley and, if possible, only when the door is closed.

Do not use the red

handle to pull the door open or closed. Disconnect electric power to the garage door opener

before making repairs or removing covers.

This product is provided with a cable of special design which, if damaged, must be replaced by a cable of the same type; such a cable may be obtained from your local Chamberlain distributor and must be fitted by a specialist.

Keep garage door balanced

. Sticking or binding doors

must be repaired. Garage doors, door springs, cables, pulleys, brackets and their hardware are under extreme tension and can cause serious personal injury.

Do not

attempt to loosen, move or adjust them.

Call for garage

door service.

Do not wear rings, watches or loose clothing

while

installing or servicing a garage door opener.

To avoid serious personal injury from entanglement,

remove all ropes connected to the garage door

before

installing the door opener. Installation and wiring must be in compliance with your

local building and electrical codes.

Connect the power

cord only to properly earthed mains. Lightweight doors of fiberglass, aluminum or steel

must be substantially reinforced to avoid door damage.

(See page 4.) The best solution is to check with your garage door manufacturer for an opener installation reinforcement kit.

The safety reverse system test is very important.

Your

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. 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 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 a 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.
