WARNING Do not use abrasive wheels for rough grinding. Large bending stresses occur during such work, which may cause abrasive wheels to shatter or break and result in 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 any composite wheel: English 1. Make certain water does not flow on a wheel that is not running, since the wheel will absorb water, which will affect wheel balance. 2. Be certain water is applied to both sides of wheel, since uneven distribution can cause "one sided" wear. 3. After finishing work, run the cutting wheel at normal operating speed for about 3 to 6 seconds without water so that the remaining water is flung off. WARNING To reduce the risk of injury from wheel breakage when wet cutting with a composite wheel that is not specifically designed for wet cutting, never store and reuse such a wheel that has been used with water. Use these wheels up the same day. TS 480i, TS 500i 11
