[. . . ] Do not force small tools or attachments to do the job of a heavy duty tool. Do not use tools for purposes not intended; for example, do not use circular saws to cut tree limbs or logs. Do not wear loose clothing or jewellery, they can be caught in moving parts. Rubber gloves and non-skid footwear are recommended when working outdoors. [. . . ] Other personal protective equipment such as dust mask, gloves, helmet and apron should be worn. Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. Use only wheels with correct size and wheels having a maximum operating speed at least as high as the highest No Load Speed marked on the tool's nameplate. When using depressed center wheels, be sure to use only fiberglassreinforced wheels. Observe the instructions of the manufacturer for correct mounting and use of wheels. Do not use separate reducing bushings or adaptors to adapt large hole abrasive wheels. Do not damage the spindle, the flange (especially the installing surface) or the lock nut. Make sure the wheel is not contacting the workpiece before the switch is turned on. Hold the tool so that sparks fly away from you and other persons or flammable materials. Pay attention that the wheel continues to rotate after the tool is switched off. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin. Position the tool so that the power cord always stays behind the machine during operation. If working place is extremely hot and humid, or badly polluted by conductive dust, use a shortcircuit breaker (30 mA) to assure operator safety. Ensure that ventilation openings are kept clear when working in dusty conditions. If it should become necessary to clear dust, first disconnect the tool from the mains supply ( use non metallic objects ) and avoid damaging internal parts. When use cut-off wheel, always work with the dust collecting wheel guard required by domestic regulation. For tools intended to be fitted with threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length. Before using the tool on an actual workpiece, test run the tool at the highest no load speed for at least 30 seconds in a safe position. Stop immediately if there is any vibration or wobbling that could indicate poor installation or a poorly balanced wheel. Check that the workpiece is properly supported.
