15(1)Checking the Idling speedIdle speed should be set to 3,000 min– -1 .If necessary correct it by means of the idle screw (the blade or the nyloncutting head must not turn when the engine is on idle).Screwing in the screw (1) will cause an increase in the engine speed,whereas backing off the screw will reduce the engine speed.STOPPINGRelease the throttle lever (4) fully, and when the engine rpm has lowered,–push the I-O switch (1) to “O” position the engine will now stop.Be aware that the cutting head may not stop immediately and allow it to slow–down fully.Run the engine for approximately one minute at a moderate speed before applying full throttle.–Note: – If the starter handle is pulled repeatedly when the choke lever remains at “ ” position, the engine will not start easily due to excessivefuel intake.– In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry theelectrode section of the spark plug.Caution during operation:If the throttle lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 min -1 or more. Never operate the engine at ahigher speed than required and at an approximate speed of 6,000 - 8,000 min-1 .Starting the warm engineSame as above, except without moving the choke lever (choke lever remains in the position “– ”).ADJUSTMENT OF LOW-SPEED ROTATION (IDLING)The cutter blade or the nylon cutting head should not run when the control lever is fully released. If necessary, adjust the idle rpm using the idleadjusting screw.Slow High(1)(4)CAUTION: The cutting tools mentioned below must only be resharpened by anauthorized facility. Manual resharpening will result in imbalances ofthe cutting tool causing vibrations and damage to the equipment.cutter blade (star blade (4 teeth), eddy blade (8 teeth))–An expert resharpening and balancing service is provided by AuthorizedService Agents.NOTE: To increase the service life of the cutter blade (star blade, eddy blade) itmay be turned over once, until both cutting edges have become blunt.RESHARPENING THE CUTTING TOOL
