Cold Start; Warm Start; Stopping The Engine; Checking The Chain Brake - Makita DCS231T Originalbetriebsanleitung

If the throttle lever is pressed before the engine starts,
then the choke lever (5) will have to be reset to the
appropriate position. (Fig. 44)

Cold start:

Push the short-circuit switch (3) forward.
Turn the choke lever (5) to position
pump 7-10 times. Slowly pull out the starter cable (4) until
you notice resistance (the piston is positioned before the
top dead centre). (Fig. 44)
Now continue to pull quickly and powerfully. The
engine will start after 2 to 4 attempts and will continue to
run (at low temperatures, several starting pulls might be
necessary).
CAUTION: Do not pull out the starter cable more than
approx. 50 cm, and lead it back by hand. For efficient
starting, it is important to pull the starter cable quickly and
powerfully.
As soon as the engine is running smoothly, gently press
the throttle lever (1) once (grasp the handle, the safety
locking button (2) will release the throttle lever) this will
cause the choke lever (5) to spring back to its original
position and the engine will then run at idling speed.
(Fig. 44)
Now release the chain brake.

Warm start:

Proceed as described under cold start, but place the
choke lever (5) to position
Important: If the fuel tank has been completely emptied
and the engine has stopped due to lack of fuel, press the
primer pump 7 - 10 times. (Fig. 44)
STOP

Stopping the engine

Put the short-circuiting switch (3) in position "STOP".
(Fig. 44)
Checking the chain brake (Fig. 45)
Do not work with the chain saw without first checking
the chain brake!
Start the engine as described (make sure you have a
good footing, and place the chain saw on the ground in
such a way that the guide bar is free of contact).
Grasp the tubular handle firmly with one hand and hold
the grip with the other.
With the engine running at moderate speed, press the
hand guard (6) in the direction of the arrow with the back
of your hand until the chain brake engages. The chain
should stop immediately.
Immediately release the throttle and release the chain
brake.
IMPORTANT: If the chain does not stop immediately in
this test, do not under any circumstances proceed
with work. Contact a MAKITA service center.

Adjusting the carburetor (Fig. 46)
The carburetor eliminates the need to adjust the idle and
main nozzles, and no such adjustment is possible.
If necessary, the idle speed can be adjusted using the
adjustment screw (11).
As installed, the carburetor has fixed nozzles for the air
pressure at sea level.
At heights above 1,000 m/3,300 feet it
may be necessary to replace the
carburetor nozzles.
Adjust the carburetor using the
screwdriver (7, which has a blade width of
4 mm).
Before undertaking the adjustment, run the engine for 3 -
5 minutes to warm it up, but not at high speed!
Set idle speed
Turning the adjusting screw (11) in (clockwise): increases
the idle speed.
Turning it out (counterclockwise): lowers the idle speed.
Caution: In no case should the chain move.
MAINTENANCE (Fig. 47)

Sharpening the saw chain

CAUTION: Before doing any work on the guide bar or
chain, always switch off the engine and pull the plug
cap off the spark plug (see "Replacing the spark plug").
Always wear protective gloves!
The chain needs sharpening when:
The sawdust produced when sawing damp wood looks
like wood flour.
The chain penetrates the wood only under great pressure.
The cutting edge is visibly damaged.
The saw is pulled to the left or right when sawing. This is
caused by uneven sharpening of the chain.
Important: Sharpen frequently, but without removing
too much metal!
Generally, 2 or 3 strokes of the file will be enough.
Have the chain resharpened at a service centre when you
have already sharpened it yourself several times.
Proper sharpening: (Fig. 48)
CAUTION: Use only chains and guide bars designed
for this saw.
All cutters must be of the same length (dimension a).
Cutters with different lengths result in rough running of the
chain and can cause cracks in the chain.
Minimum cutter length is 3 mm. Do not resharpen the
chain when the minimum cutter length has been reached;
at this point, the chain must be replaced.
The depth of the cut is determined by the difference in
height between the depth limiter (round nose) and the
cutting edge.
The best results are obtained with a depth-limiter depth of
0.65 mm (.025").
CAUTION: Excessive depth increases
the risk of kickback!
