ADJUSTING THE ENGINE
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.
• 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).
