English KombiSystem In the STIHL KombiSystem a number of different KombiEngines and KombiTools can be combined to produce a power tool. In this instruction manual the functional unit formed by the KombiEngine and KombiTool is referred to as the power tool. Therefore, the separate instruction manuals for the KombiEngine and KombiTool should be used together for the power tool.
English Safety Precautions and Working Techniques The user is responsible for accidents or risks involving third parties or their property. Special safety precautions must be observed when operating a power tool. The machine should only be provided or loaned to people familiar with this model and its operation. The KombiEngine and KombiTool User Manuals should always be handed over with the machine.

English Use your power tool only in the areas specified in the KombiTool User Manual. power tool securely. The attachment must be clear of the ground and all other obstructions because it may begin to run when the engine starts. Do not drop-start the power tool – start the engine as described in the User Manual. Note that the attachment continues to run for a short period after you let go of the throttle trigger – flywheel effect.
English Dust, fumes and smoke produced while working may be hazardous to health! Wear respiratory protection in case of heavy dust or smoke emission. If your power 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 – see also "Before Starting". Check in particular that the fuel system has no leaks and the safety equipment is fully operative.

English Store fuel only in approved safety-type fuel canisters in a dry, cool and safe location protected from light and the sun. Filling up with fuel Fueling Take care not to spill fuel while fueling and do not overfill the tank. STIHL recommends you use the STIHL filler nozzle (special accessory).

English If there is a noticeable loss of engine power A factory-new machine should not be run at high revs (full throttle off load) for the first three tank fillings. This avoids unnecessary high loads during the break-in period. As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings.
English Adjusting the Carburetor WARNING The carburetor comes from the factory with a standard setting. On this machine it is no longer necessary to adjust the carburetor. If the working tool or cutting attachment continues to run when the engine is idling, have your machine checked and repaired by your servicing dealer.
