2.Safety PrecautionsIf the engine is started up in thecourse of repairs or maintenancework, observe all local and countryspecific safety regulations as wellas the safety precautions andwarnings in the instruction manual.Gasoline is an extremely flammablefuel and can be explosive in certainconditions.Always wear suitable protectivegloves for operations in whichcomponents are heated forassembly or disassembly.Improper handling may result inburns or other serious injuries.Do not smoke or bring any fire,flame or other source of heat nearthe fuel. All work with fuel must beperformed outdoors only. Spilledfuel must be wiped awayimmediately.Always perform leakage test afterworking on the fuel system and theengine.Series 4144 Components FC, FS, KM3

3.4Tightening TorqueseDG and P (Plastoform) screws are used in polymer and light metal components. These screws form apermanent thread when they are installed for the first time. They can be removed and installed as often asnecessary without impairing the strength of the screwed assembly, providing the specified tightening torque isobserved.For this reason it is essential to use a torque wrench.FastenerThread sizeFor ewScrewScrewP 6x14M 5x30P 5x14M5P 4x12D 6x28D 5x20M 6x35M 6x25P 5x20M 5x20P 5x20M 5x14M 6x30M 6x14D 5x20D 5x20M 4x9Series 4144 Components FC, FS, KMLine limiting blade/deflectorControl handle/handle/nut with washerFilter cover/filter housingFilter housing/carburetor/spacer flangeThrottle cable/engine housingGearbox/drive tube clamp (FS 56)Shroud/cylinderClamp/clamp block/clampClamp/loop handleEngine housing/shroudEngine housing/crankcaseEngine housing torsion lock/drive tubeDeflector/gearbox (FS 56)Deflector/drive tube/nut /FS 40,50)Clamp/drive tube/harness ringStarter cover/crankcaseStarter cover/engine panEnd 4.04.55.04.56.06.02.05
