7-5. Chain brake

The EA3200S, EA3201S, EA3202S, EA3203S, EA3201SG,
EA3203SG comes with an inertia chain brake as standard
equipment. If kickback occurs due to contact of the guide‑bar
tip with wood (see SAFETY PRECAUTIONS 3‑6 "Kickback"
and Fig. 11), 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 immediately in case of an
emergency.
IMPORTANT: NEVER run the saw with the chain brake
activated (except for testing, see 7‑13 "Checking the chain
brake")! Doing so can very quickly cause extensive
engine damage!
ALWAYS release the chain brake
before starting the work!

7-6. Fuel

CAUTION:
This saw is powered by mineral-oil products (gasoline and oil).
Be especially careful when handling gasoline.
Do not smoke. Keep tool well away from open flames,
spark, or fire (explosion hazard).

Fuel mixture

This tool is powered by a high‑performance air‑cooled
two‑stroke engine. It runs on a mixture 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.
Model EA3201SG and EA3203SG accept Brazilian gasoline
(E25).
In order to obtain an optimum engine output and to protect
your health and the environment use unleaded fuel only.
To lubricate the engine, use a synthetic oil for two‑stroke air‑
cooled engines (quality grade JASO FC or ISO EGD), which
has to be added to the fuel. The engine has been designed
for use of MAKITA high‑performance two‑stroke engine oil
and a mixture ratio of only 50:1 to protect the environment.
In addition, a long service life and reliable operation with a
minimum emission of exhaust gases are ensured.
MAKITA high‑performance two‑stroke engine oil is available in
the following sizes to suit your individual requirements:
1 l order number 980 008 607
100 ml order number 980 008 606
In case MAKITA high‑performance two‑stroke engine oil is not
available, it is urgently recommended to use a mixture ratio of
25:1 with other two‑stroke engine oils, as otherwise optimum
operation of the engine cannot be guaranteed.
Caution: Do not use ready-mixed fuel from petrol
stations.
The correct mixture ratio:
50:1 when using MAKITA high‑performance two‑stroke
engine oil, i. e. mix 50 parts gasoline with 1 part oil.
25:1 when using other synthetic two‑stroke engine oils
(quality grade JASO FC or ISO EGD), i. e. mix 25 parts
gasoline with 1 part oil.
(Fig. 50)
Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of the
guide bar combined with the inertia 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.

NOTE:
For preparing the fuel‑oil mixture first mix the entire oil quantity
with half of the fuel required, then add the remaining fuel.
Thoroughly shake the mixture before filling it into the chain saw
tank.
It is not wise to add more engine oil than specified to
ensure safe operation. This will only result in a higher
production of combustion 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 through evaporation, especially at high temperatures.
Aged fuel and fuel mixtures can cause starting problems
and damage the engine. Purchase only that amount of fuel,
which will be consumed over the next few months. At high
temperatures, once fuel has been mixed it should be used up
in 6‑8 weeks.
Store fuel only in proper containers, in dry, cool, secure
locations!
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 desiccate. 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!
