– Open the choke lever progressively while checking the engine operation. Be sure to open the choke lever to the full in the end. – In cold or when the engine is cooled down, never open the choke lever suddenly. Otherwise, the engine may stop. 7) Warm-up operation Continue warm-up operation for 2 to 3 minutes. OPEN CLOSE Carburetor Primer Pump Note: – If the starter handle is pulled repeatedly when the choke lever remains at “CLOSE” position, the engine will not start easily due to excessive fuel intake. – In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry the electrode 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 a higher speed than required and at an approximate speed of 6,000 - 8,500 min-1. 1 B:B: 1) Push the primer pump repeatedly. 2) Keep the throttle lever at the idling position. 3) Pull the recoil starter strongly. 4) If it is difficult to start the engine, open the throttle by about 1/3. Pay attention to the cutter blade which may rotate. Attention in Operation When the engine is operated upside down, white smoke may come out from the muffler. STOPPING 1) Release the throttle lever (2) fully, and when the engine rpm has lowered, set the I-O switch to STOP the engine will now stop. 2) Be aware that the cutting head may not stop immediately and allow it to slow down fully. MS-245.4 C MS-245.4 CE MS-245.4 U MS-245.4 UE STOP (1) (2) STOP (1) (2) ADJUSTMENT 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 LOW-SPEED 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 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. – The carburetor is generally adjusted before shipment. If it is necessary to readjust it, please contact Authorized Service Agent. Adjusting screw Carburetor RESHARPENING THE CUTTING TOOL CAUTION: The cutting tools mentioned below must only be resharpened by an authorized facility. Manual resharpening will result in imbalances of the cutting tool causing vibrations and damage to the equipment. – cutter blade An expert resharpening and balancing service is provided by Authorized Service Agents. NOTE: To increase the service life of the cutter blade it may be turned over once, until both cutting edges have become blunt. 1 NYLON CUTTING HEAD NYLON CUTTING HEAD 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. 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 out properly 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 the throttle lever fully. Repeat this procedure until the nylon cord feeds out to the proper length. 2. 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. 3. 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.” Replacing the nylon cord – First, stop the engine. – 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). – 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. – Mount the spool in the housing so that the grooves and protrusions on the spool match up with those in the housing. Keep the side with letters on the spool visible on the top. Now, unhook the ends of the cord from their temporary position and feed the cords through the eyelets to come out of the housing.
