[. . . ] 2) Be aware that the cutting head may not stop immediately and allow it to slow down fully. When it is necessary to adjust the low-speed rotation (idling), perform it by the carburetor adjusting screw. If it is necessary to change the rotation speed, regulate the adjusting screw (illustrated on the left), with Phillips screwdriver. ­ Turn the adjusting screw to the right, and the engine rotation will increase. Turn the adjusting screw to the left, and the engine rotation will drop. CAUTION : The cutting tools mentioned below must only be resharpened by an authorized facility. NOTE : To increase the service life of the cutter blade (star blade, eddy blade) it may be turned over once, until both cutting edges have become blunt. The nylon cutting head is a dual string trimmer head capable of both automatic and bump & feed mechanisms. The nylon cutting head will automatically feed out the proper length of nylon cord by the changes in centrifugal force caused by increasing or decreasing rpms. However, to cut soft grass more efficiently, bump the nylon cutting head against the ground to feed out extra cord as indicated under operation section. Low speed (under 4, 800/min) is not suitable, the nylon cord will not feed out properly at low speed. If the nylon cord does not feed out automatically proceed as follows: 1. Release the throttle lever to run the engine idle and then squeeze the throttle lever fully. Repeat this procedure until the nylon cord feeds out to the proper length. If the nylon cord is too short to feed out automatically with the above procedure, bump the knob of the nylon cutting head against the ground to feed out the nylon cord. If the nylon cord does not feed out with procedure 2, rewind/replace the nylon cord by following the procedures described under "Replacing the nylon cord". ­ Press on the housing latches inward to lift off the cover, then remove the spool. ­ Hook the center of new nylon cord into the notch in the center of the spool, with one end of the cord extending about 80mm (3-1/8") more than the other. Then wind both ends firmly around the spool in the direction of the head rotation (left-hand direction indicated by LH and right-hand direction by RH on the side of the spool). ­ Wind all but about 100mm (3-15/16") of the cords, leaving the ends temporarily hooked through a notch on the side of the spool. Now, unhook the ends of the cord from their temporary position and feed the cords through the eyelets to come out of the housing.
