Stihl GS 461 Rock Boss174 Product Instruction Manual - Page 7

WARNING Never modify a concrete cutter in any way. Only STIHL branded parts and cutting attachments expressly approved by STIHL for use with the specific STIHL concrete cutter model are recommended. Although certain other parts or attachments may be useable with the STIHL powerhead, their use may, in fact, be extremely dangerous. If this tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work. Check in particular that the fuel system is tight (no leaks) and that the controls and safety devices are working properly. Do not continue operating this machine if it is damaged. In case of doubt, have it checked by your STIHL servicing dealer. Diamond abrasive chain The diamond abrasive chain, guide bar and chain sprocket must match each other and your concrete cutter. If chains are used that are not STIHL branded, over-aggressive cutting while using the tip of the bar cannot be ruled out, i.e., when exposed leading edges of the diamond segments hammer against the workpiece. This can damage the chain and other components and may lead to increased reactive forces (kickback). See the section entitled "Reactive Forces." Only use diamond abrasive chain for the specified materials, observe diamond abrasive chain codes. Always cut with water, see the chapter entitled "Sample applications." Before fitting used diamond abrasive chains, check that they are not cracked, chipped or have damaged or missing segments; check also that there are no signs of overheating (a bluish discoloration), which could mean an increased risk of breakage. Never use diamond abrasive chains that have any of these conditions. Consult your servicing dealer. THE USE OF THE POWER TOOL Transporting the Power Tool WARNING To reduce the risk of injury from diamond abrasive chain contact, never carry or transport your power tool with the diamond abrasive chain moving. It may be carried only in a horizontal position. Grip the front handle in a manner that the machine is balanced horizontally. Keep the hot muffler away from your body and the cutting attachment behind you. WARNING Always switch off the engine, and fit the chain guard (scabbard) over the diamond abrasive chain and guide bar before transporting the power tool over long distances. When transporting it in a vehicle, properly secure it to prevent turnover, fuel spillage and damage to the unit. English Fuel Your STIHL power tool uses an oilgasoline mixture for fuel (see the chapter on "Fuel" of your instruction manual.) WARNING Gasoline is an extremely flammable fuel. If spilled and ignited by a spark or other ignition source, it can cause fire and serious burn injury or property damage. Use extreme caution when handling gasoline or fuel mix. Do not smoke or bring any fire or flame near the fuel or the power tool. Note that combustible fuel vapor may escape from the fuel system. WARNING Dust may collect on the powerhead, especially around the carburetor, and may absorb gasoline resulting in a risk of fire. Clean dust from the powerhead regularly. Fueling Instructions WARNING Fuel your power tool in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refueling. Gasoline vapor pressure may build up inside the fuel tank depending on the fuel used, the weather conditions and the tank venting system. GS 461 5
