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 2200–2800 rpm.
WARNING
When the engine is idling the cutting
attachment must under no circumstances
rotate.
Air fi lter (Fig. 30)
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.

Cleaning the air fi lter
Remove the air fi lter cover and the fi lter (18). 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. 31)
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.
Spark plug (Fig. 32)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi lter
○ Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting diffi culties. If the engine is low on power,
diffi cult to start or runs poorly at idling speed, always
check the spark plug fi rst. If the spark plug is dirty,
clean it and check the electrode gap. Re-adjust
if necessary. The correct gap is 0.024˝ (0.6 mm).
The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly
eroded.

Muffl er (Fig. 33)
Remove the muffl er and clean out any excess
carbon from the exhaust port or muffl er inlet every
100 hours of operation.
