Trigger on idle position (released). Choke towards (open position ). Press the primer bulb (C) several times until you see fuel going back to carburetor through pipe (D). Pull starter rope. WARNING: when the throttle (B) advance is engaged, the head or blade rotates. 6) ENGINE STOPPING Press the stop switch moving it to STOP position 0. WARNING: when the engine is switched off rotating parts, blade or nylon string head, will keep on rotating for a few seconds. Hold the machine until all parts come to a standstill. N.B. In an emergency the above mentioned delay in stopping may be shortened by touching blade parallel on the ground. A A L. CARBURETTOR ADJUSTMENT The carburetor is adjusted for normal operation during production. The carburetor has three adjustment possibilities: L: The needle screw (L) governs the fuel flow at low speed and also the acceleration from low to full speed. To set low speed screw (L): close screw (L) turning it clockwise without forcing . Then open screw 1 full turn (counterclockwise ). If acceleration is not smooth, open another 1/8 turn to increase fuel flow . H: The needle screw (H) governs fuel flow at high speed (throttle valve fully open). M. REGULAR MAINTENANCE From time to time ensure all screws are tight. Replace damaged, worn, cracked or warped blades. Always make sure nylon string head or blade have been assembled correctly (see sections NYLON STRING HEAD and BLADE ASSEMBLY) and blade fastener is tightened. 1) AIR FILTER CLEANING (at least every 25 working hours). A dust clogged air filter may cause carburetor problems. This may prevent the engine from reaching its maximum speed and cause high fuel consumption and/or difficult starting. Remove filter cover as shown in figure 1. Carefully clean the inside of filter box. The filter can also be cleaned with compressed air. 2) Every 50 working hours inject the gearcase with gear grease under high pressure through hole (C). 3) SPARK PLUG From time to time (at least every 50 hours) remove and clean the spark plug and check N. REPLACING NYLON LINE 1) Loosen the locking nut on the base of the nylon head by turning it clockwise. 2) Remove the base cover assembly. Remove the empty spool from the housing and discard any remaining line. REWINDING NEW LINE 3) Prepare 2 lengths (8ft each) of 2.4 mm nylon line. Thread 1 end of each line into the two holes on opposite sides of the spool. Pinch the exposed ends flat with a pair of pliers to prevent them slipping through the hole. 4) Wind the two lines in the same direction around the spool. To set high speed screw (H) : close screw (H) turning it clockwise without forcing . Then open screw 1 full turn (counterclockwise ). If the engine speed is too high open the screw about 1/8 turn (counterclockwise ) I: The (I IDLE) screw controls the throttle opening to govern idle speed (2,800 min-1) adjust as necessary. CAUTION: increased idle speed may cause blade or nylon string head mo...
