A:ASSEMBLY INSTRUCTIONS

If Your Opener Is Supplied Fully Assembled, Please Disregard This Page.

NOTE: The Tee Rail/Chain Assembly is packaged separately from the Power Unit. The Inner Trolley half, Front Idler Sprocket, Chain, Restraining Device and Limit Cams are assembled on the Tee Rail at the factory. Follow the steps outlined below to complete assembly prior to installation. Refer to the component identification illustrations on the previous page.

STEP 1: Protect the Power Unit cover from scratching during assembly by placing it on cardboard. Remove the two 5/16"-18 washered nuts and save them for later use.

STEP 2: Position the Tee Rail/Chain Assembly box near the Power Unit. Open the box and locate the Installation Hardware Packet.

STEP 3: Locate the Outer Trolley half (packaged with the Power Unit) and slide it onto the Tee Rail/Chain Assembly with the arrow on the Trolley pointing toward the Door (Front Idler).

STEP 4: Using a 1/2" wrench, loosen the outer nut on the Chain Tension Bracket until it is at the end of the threaded rod. Remove and discard the small "S" hook used to keep the chain tight during shipping.

STEP 5: Loop the chain around the Idler and Drive Sprocket on
top of the Power Unit and then position the Tee Rail on the studs.	CHAIN

INNER MASTER CHAIN

NUT LINK

Slightly tension the Chain by tightening the outer nut on the Chain

Tension Bracket. Remove and discard the tape at each end of the Tee Rail Assembly. After double-checking the Chain's alignment with the Drive Sprocket and Front Idler Wheel, use the inner and outer adjusting nuts on the Chain Tension Bracket to adjust the chain to the proper tension, making sure the chain does not twist. When correctly adjusted, the Chain should show no droop and be approximately 1/2" above the base of the Tee Rail.

NOTE: If the chain is too loose or too tight, improper operation and/or excessive sprocket noise may result.

STEP	6:	Position the open and	104365

accept the Limit Cams on the chain, as shown. Install the Chain Guard by sliding the key-shaped hole onto

the groove on the Idler Sprocket

Shaft and fully seating the rear hole over the Drive Sprocket Shaft. The Limit Cams are installed at the factory. Their settings should be considered temporary and may be

changed as required during installation.

STEP 7: Install the Rubber Bumper into its mounting hole on the Tee Rail (see illustration above for location). Secure the Bumper to the bottom of the Tee Rail using one 5/16"-18 X 1" hex head bolt and one 5/16"-18 washered nut (supplied) Tighten the bolt a MAXIMUM of 1.5 turns after the bolt and nut are snug.

STEP 8: Recheck the nuts used to secure the Tee Rail to the Power Unit, making sure they are tight. Recheck the Chain tension, Chain twist, Chain Guard and the position of both the Close Limit Switch and Open Limit Switch Actuators.

Assembly is now complete and you are ready to

begin installation of the opener.
