N Refit the filter cover and turn the filter cover lock to the horizontal position, Engine 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 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 295BA076 KN N Shut off the engine. N Turn high speed screw (H) counterclockwise (no more than a 3/4 turn) as far as stop. N Turn the low speed screw (L) carefully home as far as stop and then open it 1 full turn. Fine Tuning for Operation in Mountains or at Sea Level A slight correction of the setting may be necessary if engine power is not satisfactory when operating at high altitude or at sea level. BG 56, BG 56 C, BG 66, BG 86, BG 86 C, SH 56, SH 56 C, SH 86, SH 86 C English N Check the air filter and clean it if necessary. N Warm up the engine. At high altitude N Turn high speed screw (H) clockwise (leaner) – no further than stop. At sea level N Turn high speed screw (H) slightly counterclockwise (richer) – no further than stop. Adjusting Idle Speed It is usually necessary to change the setting of the idle speed screw (LA) after every correction to the low speed screw (L). N Turn the low speed screw (L) slowly Checking the Spark Plug clockwise until the engine runs and accelerates smoothly. If acceleration is good, the idle setting is too lean: N Turn the low speed screw (L) slowly counterclockwise until the engine runs and accelerates smoothly. 000BA002 KN Wrong fuel mix (too much engine oil in the gasoline), a dirty air filter and unfavorable running conditions (mostly at part throttle etc.) affect the condition of the spark plug. These factors cause deposits to form on the insulator nose which may result in trouble in operation. If engine is down on power, difficult to start or runs poorly at idling speed, first 295BA077 KN Engine stops while idling check the spark plug. N Check the standard setting. N Turn the idle speed screw (LA) clockwise until the engine runs smoothly. Erratic idling behavior If acceleration is poor even though the standard setting is correct, the idle setting is too rich: N Remove spark plug as described in chapter "Starting / Stopping the Engine". N Clean dirty spark plug. N Check the electrode gap (A) and readjust if necessary – see "Specifications". N Use only resistor type spark plugs of the approved range. BG 56, BG 56 C, BG 66, BG 86, BG 86 C, SH 56, SH 56 C, SH 86, SH 86 C English Rectify problems which have caused fouling of spark plug: – Too much oil in fuel mix. – Dirty air filter. – Unfavorable running conditions, e.g. operating at part load. Fit a new spark plug after approx. 100 operating hours or earlier if the electrodes are badly eroded. 2 1 To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL. Always press spark plug boot (2) snugly onto terminal (1) of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be attached.) A loose connection between spark plug boot and ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire. 002BA071 KN Engine Running Behavior If engine running behavior is unsatisfactory even though the air filter is clean and the carburetor is properly adjusted, the cause may be the muffler. N Have the muffler checked for contamination (carbonization). STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. Rewind Starter To help prolong the wear life of the starter rope, observe the following points: N Pull the starter rope only in the direction specified. N Do not pull the rope over the edge of the guide bushing. N Do not pull out the rope more than specified. N Do not allow the starter grip to snap back, guide it back into the housing slowly – see chapter on "Starting / Stopping the Engine." Have a damaged starter rope replaced by your dealer before it breaks completely. STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. BG 56, BG 56 C, BG 66, BG 86, BG 86 C, SH 56, SH 56 C, SH 86, SH 86 C English Storing the Machine For periods of 3 months or longer N Drain and clean the fuel tank in a well ventilated area. N Dispose of fuel properly in accordance with local environmental requirements. N Run the engine until the carburetor is dry – this helps prevent the carburetor diaphragms sticking together. N Thoroughly clean the machine – pay special attention to the cylinder fins and air filter. N Store the machine in a dry, high or locked location, out of the reach of children and other unauthorized persons. Inspections andMaintenance by D...
