Maintenance - Tanaka TCS 40EA Instruction Manual

36. Pressure on bottom
37. Tension side
38. Pressure side
39. Relative depth of saw cuts
Thick log, larger than guide bar length
Begin by cutting on the opposite side of the log.
Pull the saw towards you, followed by previous
procedure. Make a boring cut if the log is close to
the ground. Finish with a top cut. (Fig. 33)
WARNING
KICKBACK DANGER
Do not attempt a boring cut if you are not properly
trained. A boring cut involves the use of the nose of
the guide bar and can result in kickback. (Fig. 34)
If the saw gets stuck
Stop the engine. Raise the log or change its
position, using a thick branch or pole as a lever. Do
not try to pull the saw free. If you do, you can deform
the handle or be injured by the saw chain if the saw
is suddenly released.

Carburetor adjustment (Fig. 35)
WARNING
Never start the engine without the complete side
case.
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.
WARNING
When the engine is idling the cutting attachment
must under no circumstances rotate.
NOTE
Some models sold in areas with strict exhaust
emission regulation do not have high and low
speed carburetor adjustments. Such adjustments
may allow the engine to be operated outside of their
emission compliance limits. For these models, the
only carburetor adjustment is idle speed.
If you are not familiar with this type of adjustment,
please ask for assistance from your Tanaka dealer.
Air fi lter (Fig. 36)
The air fi lter (40) must be cleaned from dust and dirt
in order to avoid:
○ Carburetor malfunctions.
○ Starting problems.
○ Engine power reduction.
