■ADJUSTING THE ENGINE
WARNING
Continued rotation of the blade after the throttle lever is set to the idling position could be dangerous. If the blade continues to rotate even after readjusting the idling adjustment screw, the throttle lever, throttle wire, or clutch might be faulty. Contact the shop where you bought this product, and ask it to check and repair the trouble.
IMPORTANT
•The idling engine speed is adjusted when this product is shipped from the factory, but it might need to be readjusted according to changes in operation conditions (e.g. changes in the stability of the engine, air density, etc.). When readjustment is necessary, try to do so as described below. If this is difficult, contact the shop where you bought this product, and ask it to implement the readjustment.
•Make sure the throttle wire is parallel with the flexible shaft. If the throttle wire is twisted, straighten it.
•If the flexible shaft is bent, the play of the throttle wire changes. When you adjust the idling, bend the flexible shaft and adjust the idling in a standing position similar to the position in which you actually use the machine.
How to adjust the idling revolution speed
Warm up the engine at a medium speed for a few minutes after starting it. Turn the idling adjustment screw on the carburetor body using the screwdriver supplied as a standard accessory, and adjust the idling revolution speed to an appropriate value (when the throttle lever is returned to its original position, the blade does not rotate, and the engine does not stop).
