User manual CHAMBERLAIN BAS300

[. . . ] Watch the moving door and keep people away until it is completely opened or closed. Set up permanent warning notices concerning the danger of the entrapment of body parts at conspicuous sites or close to fixed control or regulation equipment. Permanently fix the sign for the manual release device close to its respective actuating element. Use caution when operating manual release if the door is open, since it may fall rapidly if out of balance or if springs are weak or broken. [. . . ] This accessory allows manual operation of the garage door from outside in case of power failure. The bearing (sheet metal angle) in which the revolving rods to the side of the door are guided, must be fixed extremely rigidly and must be lubricated with grease later after the installation has been completed. On the drive side the revolving rods are fitted with sleeves and are only pushed onto the drive. A small screw with an internal hex head in the sleeve secures the rod from slipping out. It is strongly recommended that the side arms are first fixed before the revolving rods are cut to the required dimension. Whether the bent or straight telescopic door drive arms are used depends on the amount of space available at the side. Where the drive arm is attached to the frame depends on the door type and the amount of mounting space available. As close as possible to the point at which the door turns (swings) is ideal. This attachment should be welded to be as stable as possible since high forces are transferred to it. Straight telescopic arms operate alongside the door arms which turn the door (the arm which turns the door does not cross the path of the telescopic drive arm). There is sufficient space on the door frame to fix the drive arms to the side, top or bottom. Bent telescopic arms are fitted over the door arms which turn the door and are attached if insufficient space is available at the side to avoid contact. Both types of telescopic arm may only be pulled out to 80% of their full path (max. In the case of small doors it may be necessary to shorten the telescopic arms. The telescopic arms must be lubricated before assembly so that they function smoothly. Once the side telescopic arms are mounted the exact length of the revolving rods can be established. On the telescopic arms are sleeves which are pushed into the revolving rods. If desired this connection can be secured by drilling through and using 10 mm pins or a welded connection is also possible. The second motor does not have a limit switch and also has no controller. It is operated as the "twin" of the first motor and is wired into the controller like the first motor. Door strengthening rails are to be used for thin-walled doors or doors which are not torsionally stiff. the rails available as accessories can also be adjusted in height and permit simple fixing of the drive cover. [. . . ] Unlatching: In a recess at the back of the plastic cover is an unlatching key. Take it out and push it into the marked opening which is also on the back of the drive. By turning it clockwise through about 180° the drive is unlatched. Latching: With the unlatching key pushed in turn it clockwise until you feel a solid resistance. [. . . ]
