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. Be sure the cutting
attachment stop turning when the engine idle. 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 Tanaka dealer.
NOTE
Standard Idle rpm is 2,800 – 3,200
min
-1
.
WARNING
When the engine is idling the cutting
attachment must under no circumstances
rotate.

order to avoid:
○ Carburetor malfunctions

Cleaning the air fi lter
Open the air fi lter cover and the fi lter (21). Rinse it in
warm soap suds. Check that the fi lter is dry before
reassembly. An air fi lter that has been used for some
time cannot be cleaned completely. Therefore,
it must regularly be replaced with a new one. A
damaged fi lter must always be replaced.
Fuel fi lter (Fig. 23)
Drain all fuel from fuel tank and pull fuel fi lter line
from tank. Pull fi lter element out of holder assembly
and rinse element in warm water with detergent.
Rinse thoroughly until all traces of detergent are
eliminated. Squeeze, do not wring, away excess
water and allow element to air dry.
NOTE
If element is hard due to excessive dirt buildup,
replace it.
