English ELECTRICAL SAFETY • Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adaptor plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.
TOOL USE AND CARE • Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. • Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. • Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
English missing or damaged. If grinding wheel or accessory loosens, it may dismount from the machine and may cause serious personal injury. • Always use proper guard with grinding wheel. A guard protects operator from broken wheel fragments and wheel contact. • Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories running over rated speed can fly apart and cause injury.
• When the wheel is pinched or bound tightly by the workpiece, the wheel stalls and the motor reaction drives the unit rapidly back toward or away from the operator. • Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: • Maintain a firm grip with both hands on the unit and position your body and arm to allow you to resist kickback forces.
