Drive Hand Chain Handing Sprocket For models H and HJ with manual hoist hand chain systems, the handing of the operator must be deter- mined at the time of order. The handing is indicat- ed by last letter of the model name (R or L). The hand chain wheel can not be switched on site.
OPERATOR MOUNTING Before your operator is installed, be sure the door has been properly aligned and is working smoothly. The oper- ator may be wall mounted or mounted on a bracket or shelf. If necessary, refer to the operator preparations on page 3.
7. Install Hand Chain (Models H and HJ only) 8. Mount Chain Keeper / Keyhole Bracket Place hand chain around hand chain wheel. Be Using suitable hardware mount the chain keeper sure to pass it through both openings in the chain approximately 4 feet above the floor, near the free guide.
If your door does not have bottom safety photo eyes or safety edge and you wish to add a safety device to your WIRING: application, please contact your local LiftMaster Authorized Dealer. For wiring of your sensing device to the operator, refer to the wiring diagrams supplied on pages 13 and 14.
Failure to do so may result in severe injury to persons and/or damage to operator. The operator electrical box is only to be accessed by trained “LIFTMASTER” technicians. If service is required contact your local LIFTMASTER dealer.
On all models with B2 control wiring, a terminal bracket marked R1 R2 R3 is located on the outside of the electri- cal enclosure. Any commercial type LiftMaster brand receiver may be mounted to this bracket. The operator will then open a fully closed door, close a fully open door, stop an opening door, and reverse a closing door from the radio transmitter.
BRAKE ADJUSTMENT A solenoid brake is optional on all models, and is optional on 1/3 and 1/2 horsepower models. The brake is adjust- ed at the factory and should not need additional adjustment for the the life of the friction pad. Replace friction pads when necessary.

See Self Monitoring Safety Device Options below. SELF MONITORING SAFETY DEVICE OPTIONS To use the operator in any of the Failsafe wiring modes, or Timer To Close wiring modes (TS, T, FSTS), a LiftMaster self monitoring safety device must be installed.
The auxiliary reversing benefits of the RPM sensor are designed to prevent excessive door and operator damage upon hitting a solid obstruction. LiftMaster recommends the use of safety devices for primary safety protection. To Program: 1. The open and close limits must be set before setting the RPM sensor.
