Resumen del manual
: Dispose of remaining fuel and cleaning solution properly in accordance with local environmental requirements. : Run engine until carburetor is dry, this helps prevent the carburetor diaphragms sticking together. : Remove the saw chain and guide bar, clean them and spray with corrosion inhibiting oil. : Thoroughly clean the unit, pay special attention to the cylinder fins and air filter. : If you use a biological chain and bar lubricant, e.g. STIHL BioPlus, completely fill the chain oil tank. : Store the unit in a dry and high or locked location, out of the reach of children and other unauthorized persons. Checking and Replacing Chain Sprocket : Remove the chain sprocket cover, chain and guide bar. : Disengage the chain brake: Pull hand guard toward the front handle. Replace the chain sprocket: 001BA121 KN – after using two Oilomatic chains – or sooner if the wear marks (arrows) on the sprocket are deeper than approx. 0.5 mm since this would reduce the life of the chain. You can use a gauge (special accessory) to check the depth of the wear marks on sprockets. It is best to use two saw chains in rotation with one sprocket. STIHL recommends the use of original STIHL sprockets to ensure correct operation of the chain brake. 001BA122 KN1 2 4 5 6 1 2 3 6 : Use a screwdriver to remove the E-clip (1). : Take off the washer (2) and rim sprocket (3). : Examine splines on clutch drum (4) – if wear marks are severe, fit a new clutch drum. : Pull clutch drum or spur sprocket (5) and needle cage (6) off the crankshaft. MS 290, MS 310, MS 390 English Installing spur sprocket / rim sprocket : Clean the crankshaft stub and needle cage, and lubricate with STlHL grease (special accessory). : Push needle cage on to crankshaft. : After fitting clutch drum or spur sprocket, rotate it about one turn to engage oil pump drive. : Fit rim sprocket with cavities facing outward. : Refit washer and E-clip on the crankshaft. MS 290, MS 310, MS 390 English Maintaining and SharpeningSaw Chain Correctly sharpened chain 3/8 689BA020 KN A A properly sharpened chain slices through wood effortlessly and requires very little feed pressure. Do not work with a dull or damaged chain as it will increase the physical effort required, cause high vibrations, produce unsatisfactory cutting results and a higher rate of wear. 689BA021 KN B : Clean the chain. The chain pitch (e.g. 3/8") is marked on A = Filing angle : Check the chain for cracks in the the depth gauge end of each cutter. B = Side plate angle links and damaged rivets. : Replace any damaged or worn parts of the chain and match the new parts to the shape and size of the original parts. It is absolutely essential to comply with the angles and dimensions specified below. If the saw chain is incorrectly sharpened – and in particular if the depth gauge is set too low – there is a risk of increased kickback of the chainsaw, with resulting risk of injury. Use only special saw chain sharpening files. Other files have the wrong shape and cut. Select file diameter according to chain pitch – see table “Sharpening Tools”. You must observe certain angles when resharpening the chain cutter. Chain type Angle (°) AB Rapid-Micro (RM) Rapid-Super (RS) Picco-Micro (PM/PMN) 30 30 30 85 60 85 Cutter shapes: Micro = Semi-chisel Super = Full chisel The specified angles A and B are obtained automatically if the recommended files or sharpening tools and correct settings are used. MS 290, MS 310, MS 390 English Furthermore, the angles must be the same on all cutters. If angles are uneven: Chain will run roughly, not in a straight line, wear quickly and finally break. 689BA025 KN As these requirements can be met only after sufficient and constant practice: : Use a file holder A file holder (special accessory) must be used for manual resharpening (see table "Sharpening Tools"). The correct filing angles are marked on the file holder. For checking angles : Sharpen chain frequently, take 90° 60°85° 70° 80° 0° 35° 10° 30° 689BA022 KN away as little metal as possible – two or three strokes of the file are usually enough. 689BA018 KN90° 689BA043 KN Use a STlHL filing gauge (special accessory – see table "Sharpening Tools"). This is a universal tool for checking the filing and side plate angles, depth gauge setting and cutter length. It also cleans the guide bar groove and oil inlet holes. File correctly : Select sharpening tools according to chain pitch. : Clamp the bar in a vise if necessary. : Lock the chain – push hand guard forward. : To rotate the chain, pull the hand guard against the front handle to disengage the chain brake. On models with QuickStop Super, also press down the throttle trigger interlock lever. : Hold the file horizontally (at right angle to side of guide bar) and file according to the angles marked on the file holder. Rest the file holder on the top plate and depth gauge. MS 290, MS 310, MS 390 English : Always file from the inside to the Depth gauge setting Lowering depth gauges outside of the cut...
