Abrasive Wheels Warning! Before mounting the cutting wheel, make sure that the maximum operating wheel speed is above or equal to the spindle speed of your cut-off machine as provided in the specifications of this manual. A wheel that is not so rated may shatter or break and poses a threat of serious or fatal injury to the operator and other nearby persons. Abrasive wheels for free-hand cutting are subjected to particularly high bending and compression stresses. Warning! Unauthorized wheels may be more likely to shatter or break. Use only STIHL wheels or other authorized wheels with approved RPM ratings. Read and follow any addional safety precautions that accompany the wheel. Warning! Inspect the abrasive wheel frequently and replace immediately if the abrasive wheel is cracked or warped. Cracked or warped wheels may shatter or break and cause serious or fatal personal injury. Out-ofround or unbalanced abrasive wheels increase vibration and reduce the service life of the cut-off machine. Unauthorized diamond abrasive wheels that utilize poor quality steel cores, that are not properly tensioned, or that have other design or manufacturing defects may begin to wobble during use, which can cause wheel breakage. Such wobbling can also lead to a severe binding of the wheel in the kerf, that, under certain circumstances, can then result in serious or fatal injury from reactive forces. See the section entitled "Reactive Forces including Kickback." Never use a wheel that wobbles or that has ever wobbled. Even though such a wheel may temporarily cease to wobble, e.g., if run without load, it will always be prone to wobble again under certain conditions. Replace it immediately before further use. Composite abrasive wheels are heat sensitive. Always store your cut-off machine in a place where a composite wheel is not exposed to direct sunlight or other sources of heat. Store spare composite wheels in a dry place where there is no risk of frost damage. Failure to follow these directions may cause the wheel to shatter or crack in use causing serious or fatal injury. Warning! Never use circular saw blades, carbide tipped blades, rescue blades, wood-cutting blades or toothed blades of any nature. They can cause severe personal injury from blade contact, thrown objects and / or reactive forces, including kickback. See section on "Reactive Forces." Your STIHL dealer stocks a range of special abrasive wheels for the many applications of the cut-off machine. English Warning! Use of the wrong abrasive wheel or the cutting of material for which the wheel was not designed may cause the wheel to shatter causing serious or fatal injury. Only use the abrasive wheel approved for the type of material to be cut. There are different types of abrasive wheels, each specially marked. With respect to composite wheels, for example: 1. Stone Also can be used for concrete, masonry, reinforced concrete and brick cutting. 2. Steel Can be used for all ferrous metal cutting. 3. Asphalt Also can be used for aggregate concrete cutting. 4. Ductile iron Also can be used for certain grades of cast iron (SG 17-24), bronze and copper cutting. For cutting composite materials please ask your STIHL dealer. Diamond Abrasive Wheels Diamond abrasive wheels have a much better cutting performance than composite abrasive wheels. The diamond wheels are steel centered, and diamond particles are imbedded in their cutting edges. They can be used for concrete, asphalt, natural stone, clay pipe, brick and the like. TS 410, TS 420 5
