Stihl TS 800 Instruction Manual - Page 8

English WARNING Never use circular saw blades, carbide tipped blades, rescue blades, wood-cutting blades or toothed blades of any nature on your cut-off machine. They can cause severe personal injury from blade contact, thrown objects and/or reactive forces, including kickback. See the section "Reactive Forces" in this instruction manual. Your STIHL dealer stocks STIHL branded abrasive cutting wheels suitable for the many authorized applications of this cut-off machine. WARNING Using the wrong abrasive cutting wheel or cutting material for which the wheel was not designed may cause the wheel to wobble, shatter, break or increase reactive forces, causing serious or fatal injury. See below and the section "Reactive Forces" in this instruction manual. Cutting unauthorized materials, such as wood or plastic, or using wheels that are not rated for the material being cut, can result in severe personal injury or death from wheel breakage, reactive forces or loss of control. Composite Cutting Wheels Free-hand cutting with composite cutting wheels can subject the wheels to particularly high bending and compression stress, which can increase the possibility of wheel breakage. Avoid side loading the cutting wheel and always use proper working technique. See the chapter "Sample Applications" in this instruction manual. WARNING Inspect the composite cutting wheel frequently and replace immediately if it is cracked or warped. Cracked or warped wheels may shatter or break and cause serious or fatal personal injury. Out-of-round or unbalanced wheels increase vibration, reduce the service life of the cut-off machine and may result in loss of control. Composite cutting wheels are heat sensitive. Always store your cut-off machine in a place where a composite cutting wheel is not exposed to direct sunlight or other sources of heat. Store spare composite cutting wheels flat on a level surface 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. 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 STIHL composite wheels, for example: 1. Stone Also can be used for cutting concrete, masonry, reinforced concrete and brick. 2. Steel Can be used for cutting all ferrous metal. 3. Asphalt Also can be used for cutting aggregate concrete. 4. Ductile iron Also can be used for cutting certain grades of cast iron (SG 17-24), bronze and copper. Diamond Cutting Wheels WARNING Some diamond cutting wheels that are not STIHL branded utilize poor quality steel cores, are not properly hardened or tensioned, or have other design or manufacturing defects that can result in wheel breakage, thrown segments and other safety issues, including wheel wobble. Wheels that wobble during use can result in reactive forces and present other safety issues that could result in loss of control and severe personal injury or death. Wobbling, for example, can lead to a severe binding of the wheel in the cut that, under certain circumstances, can then result in serious or fatal injury from kickback or 6 TS 700, TS 800
