Carburetor adjustment (Fig. 23)
The carburetor is a precision part that mixes air and
fuel, and it is designed to ensure high performance
from the engine. Before the tool is shipped from
the factory, its carburetor is adjusted during a
test run. Only make adjustments if it is necessary
because of environmental conditions (the climate or
atmospheric pressure), the type of fuel, the type of
two-cycle oil, etc.
WARNING
● Because the carburetor is manufactured
with a high degree of precision, do not
disassemble it.
● For this product, the only setting of the
carburetor that can be adjusted is the idle
speed (T).
● Never start the engine without the complete
clutch cover and tube assembled! Otherwise
the clutch can come loose and cause
personal injuries.
T = Idle speed adjustment screw.

the idling.
Run the engine while adjusting the idling.
(1) If the engine stops during idling
Start the engine, and slowly turn the idle speed
adjustment screw (T) in a clockwise direction
until it is in a position at which the engine rotates
smoothly. At that time, ensure that the cutting
attachment is not spinning.
(2) If the cutting attachment rotates during idling
Slowly turn the idle speed adjustment screw (T)
in a counter-clockwise direction until it is in a
position at which the cutting attachment does not
rotate. At that time, ensure that the rotation of the
engine is smooth.
WARNING
● If the cutting attachment still rotates after
adjustment of the idle speed adjustment
screw (T), immediately stop the engine and
cease use, then contact the nearest Hitachi
Authorized Service Center.
