1 wheel installation must be visually inspected prior to use, depending on whether there are cracks or damage and wheel with a wooden hammer percussion, the sound should be crisp. Before use should GB/T2493 standard rotation test, otherwise, stainless steel cutting discs prohibited the use of .

2 must be checked prior to installation on the machine spindle speed shall not exceed the maximum operating speed marked on the cutting grinding wheels discs.
3 only allows the use of a dedicated fastening wheel nut wrench, and must be symmetrically on opposite sides of the spindle in order graded gradually tighten the nut tightness should be appropriate. Prohibit the use of clamps or beat supplemental tool.
Turn off the coolant to avoid wheel imbalance.
5 aperture wheel and wheel spindle and chuck with should meet the GB4674 standard requirements.
6 new wheel must be installed under the protective cover of the situation in order to work at the following time idling speed:
Wheel diameter <400 mm wheel is not less than 2 minutes, the outer diameter of ≥ 400 mm, not less than 5 minutes when idle, do not stand in front of the operator or the tangential direction of the wheel.
7 is not specifically use face grinding wheel (for example, parallel wheel), may not end face grinding wheel, not specifically use the cylindrical grinding wheel (eg bowl, cup-shaped grinding wheel) is also not able to carry out the outer wheel grinding wheel in order to avoid fragmentation.
8 grinding wheel when the workpiece, the reinforced concrete cutting wheels workpiece is prohibited to push a lever to increase the pressure on the wheel.
9 For thin wheel and cymbals shape grinding wheel, cutting, such as excessive force, prone to stalling stuck wheel and crashed wheel phenomenon, resulting in wheel damage. Workpiece can not be stacked more than cutting a workpiece during cutting, to prevent accidents.
