17ADJUSTMENT OF LOW-SPEED ROTATION (IDLING)When it is necessary to adjust the low-speed rotation (idling), perform it by the carburetor adjusting screw.CHECKUP OF LOWSPEED ROTATION– Set the low-speed rotation to 3,000 min -1 .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.– The carburetor is generally adjusted before shipment. If it is necessary toreadjust it, please contact Authorized Service Agent.Adjusting screwCarburetorCAUTION:The cutting tools mentioned below must only be resharpened by an authorizedfacility. Manual resharpening will result in imbalances of the cutting tool causingvibrations and damage to the equipment.– metal bladeAn expert resharpening and balancing service is provided by AuthorizedService Agents.NOTE:To increase the service life of the cutter blade it may be turned over once, untilboth cutting edges have become blunt.RESHARPENING THE CUTTING TOOLOperation of Throttle LeverWith the throttle lever main unit held by hand (with the lock-off lever pushed), pull the throttle lever and the engine rotation will be increased.Release the throttle lever, and the engine will run idle again.Release the hand from the throttle lever main unit, and the lock-off lever will return automatically so that the throttle lever will not be pulled bymistake.Adjustment of Engine ROTATIONWhen adjusting the engine rotation with the throttle lever opened to the full, turn the throttle control dial. Turn the dial clockwise, and the enginerotation will be reduced. Turn the dial counterclockwise, and the engine rotation will be increased.NYLON CUTTING HEADThe nylon cutting head is a dual Petrol Brushcutter head capable of bothautomatic and bump & feed mechanisms.The nylon cutting head will automatically feed out the proper length of nyloncord by the changes in centrifugal force caused by increasing or decreasingrpms. However, to cut soft grass more efficiently, bump the nylon cutting headagainst the ground to feed out extra cord as indicated under operation section.Operation– Increase the nylon cutting head speed to approx. 6,000 min -1 .Low speed (under 4,800 min -1 ) is not suitable, the nylon cord will not feed outproperly at low speed.– The most effective cutting area is shown by the shaded area.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 thethrottle lever fully. Repeat this procedure until the nylon cord feeds out tothe proper length.2. If the nylon cord is too short to feed out automatically with the aboveprocedure, bump the knob of the nylon cutting head against the ground tofeed out the nylon cord.3. If the nylon cord does not feed out with procedure 2, rewind/replace thenylon cord by following the procedures described under “Replacing thenylon cord.”Most effective cutting areaIdle speed Full speedKnob
