Chain brake

The DCS230T and DCS232T come with an inertia chain brake as standard equipment. If kick-
back occurs due to contact of the guide-bar tip with wood (see “SAFETY PRECAUTIONS”), the
chain brake will stop the chain through inertia if the kickback is sufficiently strong.
The chain will stop within a fraction of a second.
The chain brake is installed to block the saw chain before starting it and to stop it immedi-
ately in case of an emergency.
IMPORTANT: NEVER run the saw with the chain brake activated! Doing so can very quickly
cause extensive engine damage!
NOTE:
The chain brake is a very important safety device and like any other component subject to
normal wear and tear. Regular inspection and maintenance are important for your own
safety and must be done by a MAKITA service centre.
Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of the guide bar combined with the iner-
tia of the hand guard (1) will automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand guard (1) forward (towards the tip of
the saw) with your left hand (arrow 1).
Releasing the chain brake
Pull the hand guard (1) towards you (arrow 2) until you feel it catch. The brake is now released.

Fuel

CAUTION:
This saw is powered by mineral-oil products. (gasoline (petrol) and oil.)
Be especially careful when handling gasoline (petrol).
Avoid all flame or fire. Do not smoke (explosion hazard).

Fuel mixture

The engine of the chain saw is a high-efficiency two-stroke engine. It runs on a mix-
ture of gasoline and two-stroke engine oil.
The engine is designed for unleaded regular gasoline with a min. octane value of
91 ROZ. In case no such fuel is available, you can use fuel with a higher octane
value. This will not affect the engine.
In order to obtain an optimum engine output and to protect your health and
the environment use unleaded fuel only.
For lubricating the engine use a two-stroke engine oil (quality grade: JASO FC, ISO
EGO), which is added to the fuel.
Caution: Do not use ready-mixed fuel from petrol stations.
The correct mixture ratio: 25:1 l.e. mix 25 parts gasoline with 1 part oil.
NOTE:
For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Shake the mixture thoroughly
before pouring it into the tank.
It is not wise to add more engine oil than specified to e nsu re sa fe o per at ion. T his wil l onl y r esult in a high er pr oduc ti on o f combu stion residues
which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, fuel consumption will rise
and performance will decrease.

The Storage of Fuel

Fuels have a limited storage life. Fuel and fuel mixtures age. Therefore fuel and fuel mixtures, which have been stored for too long, can cause starting
problems. Purchase only that amount of fuel, which will be consumed over the next few months.
Store fuel safely in a dry place in approved containers only.

AVOID SKIN AND EYE CONTACT

Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desic-
cate. Various skin deseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil. If oil comes into your
eyes, immediately wash them with clear water.
If your eyes are still irritated, see a doctor immediately!
SERVICE
ALWAYS release the chain brake before starting the work!
