: Now start the engine. Throttle cable : Check adjustment of the throttle cable – see " Adjusting the Throttle Cable". Tank run until dry and then refueled : Press the fuel pump bulb at least five times – even if bulb is filled with fuel. During break- in period 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. During operation After a long period of full-throttle operation, allow engine to run for a while at idle speed so that the heat in the engine can be dissipated by flow of cooling air. This protects engine- mounted components (ignition, carburetor) from thermal overload. After finishing work Wait for engine to cool down. Drain the fuel tank. Store the machine in a dry place. Check tightness of nuts and screws (not adjusting screws) at regular intervals and retighten as necessary.

Cleaning the Air Filter FS 400, 450, 480 1 2 3 256BA074 KN Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult. If there is a noticeable loss of engine power : Turn the choke knob to g : Loosen the mounting screw ( 1). : Pull off the filter cover ( 2). : Clean away loose dirt from inside the filter cover and around the filter. : Remove the filter element ( 3) and inspect it – replace if dirty or damaged. : Fit the air filter in the cover. : Fit the filter cover. FS 300, FS 350, FS 400, FS 450, FS 480 English / USA Motor Management Exhaust emissions are controlled by the design of the fundamental engine parameters and components ( e. g. carburation, ignition, timing and valve or port timing) without the addition of any major hardware. Adjusting the Carburetor General Information The carburetor comes from the factory with a standard setting. This setting provides an optimum fuel-air mixture under most operating conditions. With this carburetor it is only possible to adjust the high speed screw within fine limits. Standard Setting : Shut off the engine. : Mount approved cutting tool. : Check the air filter and replace if necessary. : Check adjustment of the throttle cable and readjust if necessary – see "Adjusting the Throttle Cable" . 255BA001 KNLA 1 LH 3/4 : Turn high speed screw ( H) counterclockwise (max. 3/ 4 turn) as far as stop. : Carefully screw the low speed screw ( L) down onto its seat. Then open it one turn counterclockwise. : Start the engine and run it until it is warm. : Adjust idle speed with the idle speed screw ( LA) so that the cutting tool does not rotate. FS 300, FS 350, FS 400, FS 450, FS 480 English / USA Adjusting Idle Speed Engine stops while idling : Carry out standard setting with the low speed screw ( L). : Turn the idle speed screw ( LA) clockwise until the engine runs smoothly – the cutting tool must not rotate. Cutting tool rotates when engine is idling : Turn the idle speed screw ( LA) counterclockwise until the cutting tool stops rotating – then turn the screw about another half to one full turn in the same direction from that position. Erratic idling behavior, poor acceleration : Carry out standard setting with the low speed screw ( L). Idle setting too lean: : Turn low speed screw ( L) counterclockwise until the engine runs and accelerates smoothly. It is usually necessary to change the setting of the idle speed screw ( LA) after every correction to the low speed screw ( L). Fine tuning the carburetor for operation at high altitude A slight correction may be necessary if the engine does not run satisfactorily: : Check standard setting. : Warm up the engine. : Turn the high speed screw (H) clockwise (leaner). Winter OperationFS 400, 450, 480 256BA047 KN 3 1 2 256BA048 KN12 3 Mount the "Intake Air Preheating" kit 4128 007 1001* to prevent the air filter and carburetor icing up at temperatures below +10°C/ + 50° F and in powdery or drifting snow. : Remove the standard air filter ( 1). : Install the special filter ( 2) for winter operation. : Push cover ( 3) up against the underside of the filter cover. This is the winter position ( upper illustration). * see " Guide to Using this Manual" FS 300, FS 350, FS 400, FS 450, FS 480 English / USA Electric Handle Checking t...
