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:

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 your Hitachi dealer.

  Standard Idle rpm is 2,800 – 3,200 rpm.
