Metabo CS 22-355 Operating Instructions - Page 13

In case of extreme dust deposits, the machine cleaning cycles must be shortened and/or a residual-current-operated circuit-breaker (RCCB) must be connected upstream. When the machine is shut down via the RCCB circuit-breaker, it must be checked and cleaned. Use only cutting discs recommended by the manufacturer that comply with the specifications of the respective safety standards for grinding materials, e.g. EN 12413. Caution! The use of other tools and accessories can result in a risk of injury. Cutting discs must be stored in accordance with manufacturer specifications and handled carefully. Wear protective gloves when handling cut-off wheels. Store the cutting disc in a dry place. With cutting discs for dry cuts, the strength may be reduced by moisture or water. Handle the cutting disc with caution. Protect the cutting disc from jolts or impacts. Always use equipment that fulfils the following minimum requirements: Only cutting discs with resinoid bonding and fibre reinforcement can be used. The maximum rotations per minute (rpm) of the cutting disc must not be lower than the machine idling speed. Adhere to the maximum cutting disc diameter (see technical data). Use no cutting discs that are thicker than 3 mm (3/ 32"). The bore of the cutting disc must fit the toolholder without any clearance. Do not use adapters or reducers. Observe the specifications of the tool or accessory manufacturer! Adhere to the cutting disc instruction manual. Use elastic cushioning layers if they have been supplied with the sanding media and if required. Be particularly cautious with the parts that are connected to the cutting disc. Take care not to damage the spindle, flange or screw. Damage to these parts can cause the cutting disc to break. It must be ensured that mounted cutting discs are installed in accordance with the manufacturer specifications. Before use, make sure the cutting discs are correctly fixed and fastened, and operate the machine in idling mode for 30 s. Immediately switch off the machine if strong vibrations or other malfunctions occur. Should they occur, inspect the machine to find the cause. When the cutting disc is used up to the wear limit (1/ 3 of the outer diameter), replace the cutting disc. Pull the plug out of the plug socket before any adjustments or servicing are performed. The cutting disc continues to rotate after the machine has been switched off. ENGLISH en Engage the spindle locking knob (8) only when the motor is inoperative. Do not touch the rotating cutting disc. Danger of injury! When the cutting disc vibrates too strongly in idling mode, it can lead to breakage. In case of irregularities during use, immediately switch off the machine and have it repaired. Secure the workpiece. Use the vice to secure the workpiece. Do not try to saw extremely small workpieces. During machining, the workpiece must be firmly supported and secured against moving. Long workpieces must be sufficiently supported. Begin cutting only after having reached the max. rpm. Use only the cutting edge of the cutting disc to cut. Do not use the lateral surface of the cutting disc for grinding jobs. When working on workpieces with curves or inclined surfaces, make sure that no lateral pressure is applied to the cutting disc. Ensure that sparks produced during work do not constitute a risk to the user or other personnel and are not able to ignite inflammable substances. Endangered areas must be protected with flameresistant covers. Make sure that fire-risk areas are always provided with suitable fire extinguishers. The workpiece can be very hot after having been machined. Caution, risk of burning! Reducing dust exposure: WARNING - Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: - Lead from lead-based paints, - Crystalline silica from bricks and cement and other masonry products, and - Arsenic and chromium from chemically treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. This also applies to dust from other materials such as some timber types (like oak or beech dust), metals, asbestos. Other known diseases are e.g. allergic reactions, respiratory diseases. Do not let dust enter the body. Observe the relevant guidelines and national regulations for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal). 13
