Important Safety Instructions For Battery Cartridge

Safety Warnings Specific for Wire Brushing Operations:

a)Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin.

b)If the use of a guard is recommended for wire brushing, do not allow interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces.

Additional safety warnings:

17.When using depressed centre grinding wheels, be sure to use only fiberglass-reinforced wheels.

18.NEVER USE Stone Cup type wheels with this grinder. This grinder is not designed for these types of wheels and the use of such a product may result in serious personal injury.

19.Be careful not to damage the spindle, the flange (especially the installing surface) or the lock nut. Damage to these parts could result in wheel breakage.

20.Make sure the wheel is not contacting the workpiece before the switch is turned on.

21.Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel.

22.Use the specified surface of the wheel to perform the grinding.

23.Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons or flammable materials.

24.Do not leave the tool running. Operate the tool only when hand-held.

25.Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin.

26.Always be sure that the tool is switched off and unplugged or that the battery cartridge is removed before carrying out any work on the tool.

27.Observe the instructions of the manufacturer for correct mounting and use of wheels. Handle and store wheels with care.

28.Do not use separate reducing bushings or adaptors to adapt large hole abrasive wheels.

29.Use only flanges specified for this tool.

30.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.

31.Check that the workpiece is properly supported.

32.Pay attention that the wheel continues to rotate after the tool is switched off.

33.If working place is extremely hot and humid, or badly polluted by conductive dust, use a short-circuit breaker (30 mA) to assure operator safety.

34.Do not use the tool on any materials containing asbestos.

35.Do not use water or grinding lubricant.

36.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.

37.When use cut-off wheel, always work with the dust collecting wheel guard required by domestic regulation.

38.Cutting discs must not be subjected to any lateral pressure.
