[. . . ] Important: Read this instruction manual carefully before putting the Petrol Brushcutter into operation and strictly observe the safety regulations!We are pleased to recommend to you the DOLMAR Petrol Brushcutter which is the result of a long development programme and many years of knowledge and experience. Please read this booklet which refers in detail to the various points that will demonstrate its outstanding performance. This will assist you to obtain the best possible result from your DOLMAR Petrol Brushcutter. [. . . ] 2) Be aware that the cutting head may not stop immediately and allow it to slow down fully. If it is necessary to change the rotation speed, regulate the adjusting screw (illustrated on the right), 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. When it is necessary to adjust the low-speed rotation (idling), perform it by the carburetor adjusting screw. CAUTION: The cutting tools mentioned below must only be resharpened by an authorized facility. NOTE: To increase the service life of the cutter 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-1) 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. " Knob Idle speed Full speed ­ 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 80 mm (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). Spool ­ Wind all but about 100 mm (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. CAUTION: Before doing any work on the Petrol Brushcutter, always stop the engine and pull the plug cap off the spark plug (see "checking the spark plug"). [. . . ] Any warranted part that is scheduled only for regular inspection in the written instructions required by subsection (d) must be warranted for the warranty period defined in Subsection (b) (2). A statement in such written instructions to the effect of "repair or replace as necessary" will not reduce the period of warranty coverage. Any such part repaired or replaced under warranty must be warranted for the remaining warranty period. (3) Any warranted part that is scheduled for replacement as required maintenance in the written instructions required by subsection (d) must be warranted for the period of time prior to the first scheduled replacement point for that part.
