English b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
English b) Do not use the power tool if the switch does not turn it on and off . Any power tool that cannot be controlled with the switch is dangerous and must be repaired. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.

English The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fl y apart. The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool.
English Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock. KICKBACK AND RELATED WARNINGS Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding.
English Wheels must be used only for recommended applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter. Always use undamaged wheel fl anges that are of correct size and shape for your selected wheel.

English PRACTICAL GRINDER APPLICATION Pressure To prolong the life of the machine and ensure a fi rst class fi nish, it is important that the machine should not be overloaded by applying too much pressure. In most applications, the weight of the machine alone is suffi cient for eff ective grinding. Too much pressure will result in reduced rotational speed, inferior surface fi...
English CAUTION Check that the work piece is properly supported. ○ Ensure that ventilation openings are kept clear when working in dusty conditions. ○ If it should become necessary to clear dust, fi rst disconnect the tool from the mains supply (use non-metallic objects) and avoid damaging internal parts.
