English / USA !Warning! It is essential to determine the exact direction of the cut before applying the abrasive wheel to the work. Wheels are constructed for radial pressure only. Lateral pressure must be avoided. Hold the cut-off machine steady. To reduce the risk of serious or fatal injury, do not change the direction of the cut during the cut as this may produce a high torsional load on the abrasive wheel and may cause it to break or shatter. !Warning! Do not use abrasive wheels for rough grinding. Large bending stresses occur during such work and abrasive wheels may shatter or break and could cause serious or fatal injury. !Warning! To reduce the risk of injury from shattered abrasive wheels: 1. Do not exceed the maximum operating speed marked on the wheel. 2. Do not use a wheel that has been dropped. 3. Test each new wheel immediately after installation for approximately one minute at maximum speed without cutting, making sure to keep bystanders away. 4. Do not cut any material for which the abrasive wheel is not authorized. 5. Do not grind on the side of the abrasive wheel. 6. Do not twist, thrust, knock or drop the machine. This can cause damage to the wheel. To achieve a clean and efficient cut, pull the abrasive wheel across the work or move it "to and fro" in the cutting direction. Do not use force to push the abrasive wheel into the work. Insert the wheel into the material only as deep as necessary to make the cut. To reduce the amount of dust created, do not cut all the way through stone and concrete materials - leave a thin piece uncut. For most such materials, this piece can be easily broken afterwards. Do not cock, jam or wedge the wheel in the cut. Always stop the engine and be sure the wheel has stopped rotating before setting down the cut-off machine. If a cut-off machine cart is used, sweep debris from the path of the wheels, as debris under one of the cart's wheels may cause flexing of the abrasive wheel. This could result in high frictional forces and thus greatly reduce the engine power available for the actual cutting work. It could also damage the abrasive wheel. STIHL recommends the use of the cart for longer cuts in a straight line. Wet Cutting with Abrasive Wheels Before wet cutting, make sure water will not damage the floor or building. !Warning! To reduce the risk of electrocution to you or bystanders, do not allow water or sludge to contact live electric wires. !Warning! To reduce the risk of injury from wheel breakage when wet cutting with a composite non-diamond wheel: 1. Never store and re-use a wheel that has been used with water. Use these wheels up the same day. TS 460 13
