OJ.! Quantity Control Other points to be observed when starting the engine: The choke lever is mechanically connected to the carburetor's choke valve. The choke valve is closed when the choke lever is on "CHOKE" and open when the chocke lever is moved away from "CHOKE". Adjusting bolt at maximum position When starting a cold engine only keep the choke lever in the "CHOKE" position until the engine begins to fire. Then open choke fully-choke lever away from "CHOKE" -even if the engine stops and you have to repeat the starting procedure. If the choke lever is left in the "CHOKE" position, the combustion chamber will flood and stall the engine. If you moved the choke lever away .from the "CHOKE" position after the engine fired and the engine still does not run after several attempts, it is already flooded. In such a case, remove and dry off the spark plug. Clear the combustion chamber by cranking the engine over several times on the starter with the spark plug still removed and the stop switch in the "STOP" position. When you now try to start, move the choke lever away from "CHOKE" - even if the engine is cold - and set the throttle trigger to the startingthrottle position. In very cold weather only open the choke slightly after starting - move choke lever to center position. Allow engine to warm up for a brief period at half-throttle. Then move choke lever away from "CHOKE" and disengage the startingthrottle lock. The oil quantity supply can be regulated with the adjusting bolt. It is positioned at the bottom side of the crankcase. By turning the adjusting bolt in clockwise direction to plus position (+) the lubricating quantity is increased, turning it anti-clockwise to minus position (-) the oil flow is decreased. To assure sufficient lubricating quantity for the cutting tool at all times the adjusting bolt should always be set at plus position (+) - max'imum oil supply. Only when using short guide bars decreasing of the lubricating supply is recommended. If the oil supply has to be put out of function completely for instance when using an attachment tool put adjusting bolt to minus position (-) press in and turn further to "0" position. A new engine or one which has been run until the ,fuel tank is dry will not start first time after fueling because the car- buretor's diaphragm pump only delivers sufficient fuel after the engine has been turned over several times. 21
