Stopping The Engine; Checking The Chain Brake; Adjusting The Carburetor - Makita EA3201S Original Instruction Manual

7-12. Stopping the engine

Depress the combination switch
NOTE: After being pressed down, the combination switch will
revert to the ON position again. The engine is switched off, but
can be turned on again without moving the combination switch.

7-13. Checking the chain brake

The chain brake must be checked before every use of the
saw!
Start the engine as described above (have a secure footing,
place the chain saw on the ground so that the chain and guide
bar are not near anything).
(Fig. 57)
Hold the front handle firmly, with your other hand on the rear
grip.

7-14. Adjusting the carburetor

(Fig. 58)
CAUTION: Carburetor adjustment may only be done by a
specialist MAKITA service center!
Do not undertake any adjustments to adjusting screws
(H) and (L) without a tachometer! Incorrect adjustment
can lead to engine damage!
A tachometer is needed for adjustments to adjusting
screws (H) and (L), because if the engine runs over its
maximum rated speed, it can overheat and run out of
lubricant. This can damage the engine!
Only adjusting screw (S) can be manipulated by the user.
If the saw chain moves in idle (i.e. without the throttle being
pressed), it is imperative to correct the idle speed!
Do not adjust the idle speed until after complete
assembly and testing of the saw!
Idle speed adjustment must only be undertaken when
the engine is warm, with a clean air filter and properly
installed guide bar and chain.
Use a screwdriver (4 mm blade) for idle adjustments.
Adjusting the idle speed
Turn adjusting screw (S) counter-clockwise (unscrew): Idle
speed decreases.
Turn adjusting screw (S) clockwise (screw in): Idle speed
increases.
Important: If the saw chain still moves during idle even
after you have adjusted the idle speed, do NOT use the
saw. Take it to a MAKITA service center!
Note:
Carburetor adjustment aids in proper functioning,
economical consumption, and safe operation.

SERVICE
IMPORTANT: To cut off the ignition current, push the
combination switch all the way down past the resistance point
to the safety position ( ).
Let the engine run at medium speed and push the handguard
(6) in the direction of the arrow using the back of your hand,
until the chain brake engages. The chain should now stop
immediately.
Bring the engine back to idle and release the chain brake.
Caution: If the chain does not stop immediately in this
test, turn off the engine immediately. Do NOT use the
chain saw in this condition! Contact a MAKITA authorized
service center.
Because of new exhaust regulations, the carburetor
adjusting screw (H) now comes with a limit feature. The
reduced adjustment range (about 180 degrees) prevents
excessively rich carburetor settings. On some models, the
adjusting screw (H) is locked. This ensures compliance with
exhaust regulations, as well as good engine functioning and
economical fuel consumption.
