Power source:   Ensure that the power source to be utilized conforms to the power source   requirements specified on the product nameplate.   2. Power switch:   Ensure that the switch is in the OFF position. If the plug is connected to a   receptacle while the switch is in the ON position, the power tool will start operating   immediately and can cause serious injury.   3. Extension cord:   When the work area is far away from the power source, use an extension cord of   sufficient thickness and rated capacity. The extension cord should be kept as short   as possible.   4. Check the receptacle:   If the receptacle only loosely accepts the plug, the receptacle must be repaired.   Contact a licensed electrician to make appropriate repairs.   If such a faulty receptacle is used, it may cause overheating, resulting in a serious   hazard.   5. Check your working environment:   Ensure the following before operation;   a. No flammable gas, liquid, or object at worksite.   b. Grinding thin steel sheet may cause a high booming sound.   In this case, place a rubber mat under the workpiece.   c. Take appropriate noise preventive measures to prevent adverse affects on the   environment by electrical noise.   d. Clear the area of children or unauthorized personnel.   6. Mounting the wheel guard:   Be sure to mount the wheel guard at an angle that will protect the operator’s body   from injury by a broken wheel piece.   WARNING:   IF NOT CORRECTLY ATTACHING A PROPER WHEEL GUARD,   IT MAY LEAD TO SEVERE INJURY OR DEATH IF THE   GRINDING WHEEL SHOULD BE BROKEN.   7. Inspect the grinding wheel carefully before mounting:   Thoroughly check that a specified grinding wheel free of cracks and splits   is mounted. Make sure that the grinding wheel is firmly clamped and has   been mounted in accordance with the instructions contained on page 12.   7-Inch Disc Grinder Operator's Manual   13   Download from Www.Somanuals.com.
