Use only approved fuel storage containers. CORRECT HANDLING OF MACHINE Attachment of shoulder strap Always wear the shoulder strap and adjust the strap length so that the cutter blade is kept parallel with the ground. Detachment The shoulder strap has a quick release latch. In an emergency, pull the red strap (A) to detach the machine from you. Be extremely careful to maintain control of the machine at this time. Do not allow the machine to be deflected toward you or anyone in the work vicinity. WARNING : Failure to maintain complete control of the machine may result in serious bodily injury or death. To reassemble, remove the spring clip (B) from the machine, place open end over the strap buckle (C) and then insert the release blade (D). B D A C 10 POINTS IN OPERATION AND HOW TO STOP Follow the applicable accident prevention regulations. Starting Move at least 3 m away from the place of refueling. Place the machine on a flat, bare surface so that the cutting blade does not contact the surface of ground or any other objects. Cold start For machine with U Handle or Loop Handle -Move the switch (1) to the “I” position. -Push gently the primer pump (A) 8 to 10 times. -Set the choke lever (B) to the “CHOKE” position (C). Note : Depress the trigger safety lock (E) before squeezing trigger. -Squeeze the trigger (F) to full throttle position and hold it, and then set the switch (1) to the “START” position and release the trigger (F). -Pull the starter until the engine tries to run (No more than 6 pulls ). -Set the choke lever to half choke position. -Pull the starter until the engine start running. After the engine runs for 30 to 45 seconds at the “START” position ( for warming up the engine ), move the choke lever to the “RUN” position ( D ). Warm Start ( Re-starting Engine ) -Set the choke lever (B) to the “RUN” position (D). Note : You do not need to pull the trigger or set the throttle-lock when the engine is warm. -Pull the starter rope until the engine runs. B D C A STOPPING Release the trigger (F) fully, and push the switch (1) to the “O” position that the engine will stop. Be aware that the cutting blade may not stop immediately and allow it to slow down fully. IDLE SPEED ADJUSTMENT Your DOLMAR engine has been adjusted at the factory for optimum performance and fuel consumption, and no further adjustment is required. Due to varying atmospheric and climatic conditions, however, you may need some minor adjustment for your area. Checking the idle-speed The idle-speed should be set to 2,800 – 3,300 rpm. If necessary, adjust the idle-speed using with a tachometer to insure the proper idle-speed. Note that the cutting blade or the nylon cutting head must not turn when the engine is on idle. Adjusting the idle rpm. Can be done by turning the idle-speed screw (A) clockwise ( for increasing the engine speed ) or counterclockwise ( for decreasing the engine speed ). If the engine does not idle properly after the adjustment, contact your nearest Dolmar dealer for service. RE-SHARPENING THE CUTTING TOOL CAUTION : The cutting blades mentioned below should only be re-sharpened by an authorized facility. Manual re-sharpening will result in imbalances of the blade causing abnormal vibrations and damage to the machine. -Cutter Blade : star blade ( 4 teeth ), eddy blade ( 8 teeth ) An expert service for re-sharpening and balancing is provided by Authorized Service Agents. NOTE : A To increase the service life of the above cutter blade, it may be turned over once until both cutting edges have become blunt. 11 NYLON CUTTING HEAD Replacing the nylon cord 1 First, stop the engine. Press on the housing latches (A) inward to lift off the cover assembly (B). Then remove the spool (D). 2 Remove any excess nylon cord from the spool. 3 Cut a length of the nylon cord that is approximately 7.5 m ( 25’ ) long. 4 Hook the center of new nylon cord into the notch (F) in the center of the spool, with one end of the cord extending about 80 mm (3” to 3-1/8”) more than the other. Then wind both ends firmly around the spool in the direction of the head rotation. 5 Put the cord ends temporarily into the notched (H) when winding being finished. Leave approximate 100 mm (4”) of the cord extended beyond the notch. 6 Place the spool into the cover. Remove the ends of the cord from the notches (H) and put them in the metal eyelets (I) on the cover. 7 Mount the spool ( cover-assembly ) in the housing so that the grooves and protrusions on the spool mach up with those in the ...
