FS 460 C-M, FS 460 C-M L, FS 490 C-M, FS 490 C-M L English 39 If engine running behavior is still unsatisfactory after servicing the air filter and adjusting the throttle cable, the cause may be the muffler. H av e t he m uf fle r c hec k ed by a s er v ic in g dealer for contamination (carbonization). STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer.If the machine is to remain out of use for approx. 3 months or more NDrain and clean the fuel tank in a well ventilated place NDispose of fuel in accordance with the regulations and having regard for the environment NRun the engine until the carburetor is dry. This helps to prevent the carburetor diaphragms sticking together. NRemove, clean and inspect the cutting attachment. Treat metal cutting attachments with protective oil. NThoroughly clean the machine NStore the machine in a dry and safe place, out of the reach of children and other unauthorized usersNUse a sharpening file (see "Special Accessories") to sharpen dull cutting attachments. In case of more serious wear or nicks: Resharpen with a grinder or have the work done by a dealer – STIHL recommends a STIHL servicing dealer. NSharpen frequently, take away as little metal as possible – two or three strokes of the file are usually enough. NResharpen the teeth (1) uniformly – do not alter the contour of the parent blade (2) in any way. See cutting attachment packaging for additional sharpening instructions. Keep the packaging for future reference. Engine Running BehaviorStoring the MachineSharpening Metal Cutting Blades 22 1 2 11 002BA042 KN

Placing power tool on the ground NShut off the engine. NLay your power tool on its back so that the cutting attachment mounting face is pointing up. Replacing Nylon Line Always check the mowing head for signs of wear before replacing the nylon line. WARNING If there are signs of serious wear, replace the complete mowing head. The nylon mowing line is referred to as "nylon line" or "line" in the following. The mowing head is supplied with illustrated instructions for replacing the nylon line. Keep the instructions for the mowing head in a safe place. NIf necessary, remove the mowing head. Adjusting Nylon Line STIHL SuperCut Fresh line is advanced automatically if the remaining line is at least 6 cm (2 1/2 in) long. The blade on the deflector trims overlong lines to the correct length. STIHL AutoCut NWith the engine running, hold the rotating mowing head above the grass surface. NTap it on the ground once – fresh line is advanced and the blade on the deflector trims it to the right length. Fresh line is advanced every time the mowing head is tapped on the ground. For this reason observe the mowing head's cutting performance during operation. If the mowing head is tapped on the ground too often, the line limiting blade will unnecessarily cut off unused lengths of nylon line. Line feed operates only if both lines are still at least 2.5 cm (1 in) long. STIHL TrimCut WARNING To reduce the risk of injury, always shut off the engine before adjusting the nylon line by hand. NPull the spool up – rotate it about 1/6 turn counterclockwise until it engages – and allow it to spring back. NPull ends of the lines outward. Maintaining the Mowing Head 002BA406 KN
