Powered Abrasive Wheel Tools
To prevent the wheel from cracking, the user should be sure it fits freely on the spindle.
The spindle nut must be tightened enough to hold the wheel in place, without distorting the flange.
Follow the manufacturer's recommendations. Care must be taken to assure that the spindle wheel will not exceed the abrasive wheel specifications.
Due to the possibility of a wheel disintegrating (exploding) during start-up, the employee should never stand directly in front of the wheel as it accelerates to full operating speed.
