Forcing and excessive pressure could cause dangerous wheel breakage. • ALWAYS replace wheel if tool is dropped while grinding. • NEVER bang or hit grinding disc or wheel onto work. • Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control and kickback. • NEVER use tool with wood cutting blades and other sawblades. Such blades when used on a grinder frequently kick and cause loss of control leading to personal injury. 9 CAUTION: • After operation, always switch off the tool and wait until the wheel has come to a complete stop before putting the tool down.
