●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 filter 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 Tanaka dealer.
NOTE
Standard Idle rpm is 2500–3000 rpm.
WARNING
When the engine is idling the cutting
attachment must under no circumstances
rotate.
Air filter (Fig. 29)
The air filter must be cleaned from dust and dirt in
order to avoid:
○Carburetor malfunctions
○Starting problems
○Engine power reduction
○Unnecessary wear on the engine parts

Cleaning the air filter
Remove the air filter cover and the filter (25). Rinse it
in warm soap suds. Check that the filter is dry before
reassembly. An air filter that has been used for some
time cannot be cleaned completely. Therefore,
it must regularly be replaced with a new one. A
damaged filter must always be replaced.
Fuel filter (Fig. 30)
Drain all fuel from fuel tank and pull fuel filter line
from tank. Pull filter 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. 31)
The spark plug condition is influenced by:
○An incorrect carburetor setting
○Wrong fuel mixture (too much oil in the gasoline)
○A dirty air filter
○Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting difficulties. If the engine is low on power,
difficult to start or runs poorly at idling speed, always
check the spark plug first. 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.
0.024˝
(0.6 mm)
Fig. 31
Muffler (Fig. 32)
Remove the muffler and clean out any excess
carbon from the exhaust port or muffler inlet every
100 hours of operation.
Fig. 32
Cylinder (Engine cooling) (Fig. 33)
The engine is air cooled, and air must circulate
freely around engine and over cooling fins on
cylinder head to prevent overheating.
Every 100 operating hours, or once a year (more
often if conditions require), clean fins and external
surfaces of engine of dust, dirt and oil deposits
which can contribute to improper cooling.
Fig. 33
NOTE
Do not operate engine with engine shroud
or muffler guard removed as this will cause
overheating and engine damage.
Angle transmission (Fig. 34)
Check angle transmission or angle gear for
grease level about every 50 hours of operation by
removing the grease filler plug on the side of angle
transmission.
If no grease can be seen on the flanks of the gears,
fill the transmission with quality lithium based
multipurpose grease up to 3/4. Do not completely fill
the transmission.

○Use asharp blade. Adull blade is more likely
to snag and thrust. Replace the fastening nut
if it is damaged and hard to tighten.
○When replacing blade, purchase one
recommended by Tanaka, with a25.4 mm
(one inch) fitting hole.
○When installing asaw blade, always face
the stamped side up. In the case of a3tooth
blade, it can be used on either side.
○Use the correct blade for the type of work.
○When replacing blades, use appropriate
tools.
○When cutting edges become dull, re-sharpen
or file as shown in the illustration. Incorrect
sharpening may cause excessive vibration.
○Discard blades that are bent, warped,
cracked, broken or damaged in any way.
NOTE
When sharpening blade it is important to
maintain an original shape of radius at the base
of the tooth to avoid cracking.
Nylon head
Nylon line replacement
○Remove the cutting body cap by pushing inward
the locking tabs on the side of the nylon head
(Fig. 36). Take out the spool (Fig. 37), hook the
new nylon line into the hole of the spool, then
wind it around the spool in two stages (Fig. 38).
When the nylon line has been wound around the
spool, temporarily fasten it in the opening of the
spool at about 4˝(10 cm) from the end. (Fig. 39)
Then thread the nylon line through the hole on
the side of the nylon head and place the cutting
body cap in reverse order of the cap removal.
Pull the right and left nylon lines until they are
secured about 6˝– 6-5/16˝(15 - 16 cm) from the
end. (Fig. 41)
