With these machines, to employ only the discs of sandpapering specifically designed for grinders of air.

Fiber discs:

* To store the abrasive discs with 40 percent with 50 percent of humidity relative and 60 to 80 degrees of F. * To store the coated abrasive discs at least 4 inches above the surface of the floors out of concrete, far from the opened windows, out of the direct sunlight, and far from the heat sources. * To store the abrasive discs coated in their original packing. * If the packing is received damaged, the product does not employ inside.

* To employ only one disc which comes into contact with entirely the trimming of help. Never not to employ a deformed disc. * To start a tool right in addition to object and to bring it until the full speed of operation before beginning grinding or sandpapering. * To always relieve the disc of fiber in the object to 5 – with 10 degrees to fish on the surface of object. * Never not to change the size or the shape of an abrasive disc or its trimming of help. * If you employ has see-with through the disc (with the hollow holes), not to start the equipment before making sure that no object exceeds by one of the holes.
