WARNING
○ The cutting attachment may be spinning during
carburetor adjustments.
○ Never start the engine without the complete
clutch cover and tube assembled! Otherwise
the clutch can come loose and cause personal
injuries.
In the carburetor, fuel is mixed with air. When the
engine is test run at the factory, the carburetor is
basically 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 fi lter is clean. When the idle
speed is correct, the cutting attachment will not
rotate. If adjustment is required, close (clockwise)
the T-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 Tanaka dealer.
NOTE
Standard Idle rpm is 3000 min
