[. . . ] Never touch the blade, grinding wheel or other moving parts during use. Never start a tool when its rotating component is in contact with the work piece. [. . . ] Inspect the grinding wheel before use to ensure that it is not chipped or cracked. Chips or cracks can cause the wheels to shatter, resulting in possible serious injury. Ensure that the grinding wheel is correctly mounted and tightened before use and run the tool at no-load speed for 30 seconds in a safe position. Stop immediately if there is considerable vibration or if other defects are detected.
