 【】 To use and maintain 
 1. Grinder before use must be more than 500 volts megger to measure the insulation resistance, and its value is not less than 0.5 MΩ. 
 2. Grinder should be carefully checked before using their parts, whether the damage or the transport of crack, if fasteners loosening, if any should be repaired and tightened. Special attention to wheel for cracks, can tap the gavel to issue clear and sound can be used. 
 3. Grinder before use, you should turn the shaft by hand to observe the rotation is flexible and light, listen to the sound with or without grazing. 
 4. Wheel drive and fan rotation direction indicators should be consistent with the direction of rotation. 
 5. Grinding machine in operation, work material and grinding wheels are not allowed to collide, we must apply a gradually increasing pressure on the wheel from impact, to avoid wheel explosion, accident. 
 6. Grinder wheel guard and repair than replace the removal of foreign, usually non-removal to ensure safety. 
 7. The use of two wheel grinders wear the biggest difference between the diameter of no more than 2
