[. . . ] This section describes the machine's safety equipment, its function and how checks and maintenance are carried out to ensure that it operates correctly. (See the chapter "What is what" to locate where this equipment is positioned on your machine. Follow the control, maintenance and service instructions described in this section. This guard is intended to prevent objects from being thrown towards the operator and to protect the operator from unintentionel contact with the cutting attachment. [. . . ] Always use the prescribed blade and guard combination, see chapter "Technical data" in the machine's Operator's Manual. Always stop the engine before starting work on any part of the cutting equipment. Ensure that the cutting equipment has stopped completely and remove the cable from the spark plug before you start to work on it. Protect your hand from injury when assembling, use the blade guard as protection when tightening with a socket spanner. The locking nut's nylon lock must not be so worn that it can be turned by hand. The safety equipment should be maintained as described in this section. If your machine does not meet any of these controls you should contact your service workshop. When adjusting the carburettor make sure the blade is held against the ground and that no one is in the immediate vicinity. Always wear boots and other equipment described in the section "Personal protective equipment" in the machine's Operator's Manual. â· Always wear working clothes and heavy-duty long trousers. â· Persons with long hair should, for personal safety, put their hair up. When the engine is switched off, keep your hands and feet away from the blade until it has stopped. â· Always drop to idling speed after each working operation. Longer periods running at full throttle without loading the engine (that is without resistance, which the engine feels from the cutting equipment when trimming) can lead to serious engine damage. â· Be especially careful when pulling the edger towards you during work. Can be thrown up into the eyes resulting in blindness or other serious injury. Children, animals, onlookers and helpers should be outside the safety zone of 15 meters (50 feet). The bevel gear unit can get hot during use and may remain so for a while afterwards. Position the angle gear so that its slot is aligned with the line on the supporting tube. Check that the support flange is not cracked due to fatigue or due to being tightened too much. Block the blade rotation by inserting locking pin in the hole behind the blade guard engaging it in the corresponding hole in the drive disc. The support flange must be fitted with its outer edge hard up against the blade. [. . . ] The support flange must be fitted with its outer edge hard up against the blade. Under no circumstances may the edge cutter blade be used without the blade guard fitted. However, before using the machine you should check that the angle gear is filled to 3/4 with grease. Normally, the grease does not need to be changed except when repairs are carried out. [. . . ]
