Carburetor adjustment (Fig. 13)
WARNING
● The cutting attachment may be spinning
during carburetor adjustments.
● Never start the engine without the complete
clutch cover (15). 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
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.
Air fi lter (Fig. 14)
The air fi lter must be cleaned from dust and dirt in
order to avoid:
○ Carburetor malfunctions.
○ Starting problems.
○ Engine power reduction.
○ Unnecessary wear on the engine parts.
○ Abnormal fuel consumption.
Clean the air fi lter daily or more often if working in
exceptionally dusty areas.
