English Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping fl ying debris generated by various operations.
English For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching.
English When wheel is pinched, snagged or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur.
English — Ensure that sparks resulting from use do not create a hazard e.g. do not hit persons, or ignite fl ammable substances; — 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;...

Grinding operation Lightly press the wheel to the material to be ground when grinding materials, high-speed revolution is necessary.
English Dressing the wheel After attaching a wheel, adjust defl ection of the wheel center by using a dresser. If the wheel center is eccentric, not only precise fi nishing cannot be achieved but also grinder vibration increases, lowering grinder accuracy and durability. A clogged or worn wheel will soil the fi...
