[. . . ] This safety alert symbol means "Caution" - failure to comply with such an instruction involves risk of personal injury or damage to property. This gate drive mechanism is designed and tested to offer appropriately safe service provided it is installed and operated in strict accordance with the following safety rules. Incorrect installation and/or failure to comply with the following instructions may result in serious personal injury or property damage. When using tools and small parts to install or carry out repair work on a gate exercise caution and do not wear rings, watches or loose clothing. [. . . ] Try and achieve the best dimension for your opening angle, as precisely as possible and suitable for all circumstances. see Table (figure 3F) for dimensions A/B. If the post is not wide enough, an extension piece must be fitted to it (figure 5B). If the post is too thick, cut out part of it to make it thinner (figure 5D)or offset the gate (figure 5C). To obtain ideal dimensions, it may be necessary to shorten or lengthen the supplied hinge plate. In the case of gates that are to be custom made, if the gate hinges are fitted on the posts appropriately, it is possible to influence dimensions A and B. Before the final mounting dimensions are determined, you should always check whether or not there is any possibility that the corner of the drive mechanism will hit the post as the gate swings. iNSTALLATION: The drive mechanism exerts considerable force against the post. Usually, acceptable mounting dimensions are obtained if the supplied hinge plate is welded directly onto the post. In the case of thick stone or concrete posts, the hinge must be welded to a base plate and attached so that the plugs cannot work loose during operation. Heavy-duty plugs where a threaded rod is bonded into the masonry stress-free are more suitable for this purpose than steel or plastic straddling plugs. In the case of brickwork pillars, bolt on a relatively large steel plate that covers several bricks and then weld the hinge plate to it. An angle plate attached over the corner of the post is also a good means of fixing the operators. ACCESSORY TIP 1: For round posts an accessory fitting can be mounted that simplifies the setting of the A/B dimension (model 207917). ACCESSORY TIP 2: For gates swinging outwards a special fitting can be ordered. Make sure your gate equipment operates perfectly. The gate must run evenly and smoothly and must not stick at any point. Remember that the ground level may be several centimeters higher in winter. The gate must be stable and as free of backlash as possible in order to prevent any unwanted to and fro movement. The more smoothly the gate leaf runs, the more sensitive the force adjustment must be. Note down any materials you still need and obtain them before starting to install. GATE TYPES 2 The gate type determines the location where the drive mechanism is installed. [. . . ] As soon as the gate moves or the drive runs, the gear locks again. Use the lock to protect the lever against unauthorized release. iNSTALLING THE DRIVE ARMS 7 Release the drive. Push the released drive onto the fittings and secure it by using the supplied bolts, nuts and rings. [. . . ]
