in the carburetor, fuel is mixed with air. When the engine is test run
at the factory, the carburetor is adjusted. A further adjustment may
be required, according to climate and altitude.The carburetor has
one adjustment possibility:
T = Idle speed adjustment screw.
Idle speed adjustment (T)
Check that the air filter is clean. When the idle speed is correct, the
cutting attachment will not rotate, if adjustment is required, close
(clockwise) theT-screw, with the engine running, until the cutting
attachment starts to rotate. Open (counter-clockwise) the screw
until the cutting attachment stops. You have reached the correct idle
speed when the engine runs smoothly in all positions well below
the rpm when the cutting attachment starts to rotate.
if the cutting attachment still rotates after idle speed adjustment,
contact HiTACHi dealer.
/!\_ WARNING!
When the engine is idling the cutting attachment must under no
circumstances rotate.
NOTE!
Some models sold areas with strict exhaust emission regulation
do not have high and low speed carburetor adjustments. Such
adjustments may allow the engine to be operated outside of their
emission compliance limits. For these models, the only carburetor
adjustment is idle speed.
