First, push the sprocket cover (3) into its fixture (4). Make
sure that the pin (8) of the chain tightener is in the hole on
the guide bar. Then push it over the retaining bolt while
lifting the saw chain (9) over the chain catch (13).
Manually tighten the retaining nut (2). (Fig. 32)
Tightening the saw chain
Turn the chain adjusting screw (5) to the right (clockwise)
until the chain engages the guide groove of the bottom
side of the bar (see circle).
Slightly lift the end of the guide bar and turn the chain
adjusting screw (5) to the right (clockwise) until the chain
rests against the bottom side of the guide bar.
While still holding up the tip of the guide bar, tighten the
retaining nuts (2) with the universal wrench. (Fig. 33)
Checking the chain tension (Fig. 34)
The tension of the chain is correct if the chain rests
against the bottom side of the guide bar and can still be
easily turned by hand.
While doing so the chain brake must be released.
Check the chain tension frequently - new chains tend to
get longer during use! When checking the chain tension
the engine must be switched off.
NOTE:
It is recommended to use 2 - 3 chains alternatively.
In order to guarantee uniform wear of the guide bar the
bar should be turned over whenever replacing the chain.
Chain brake (Fig. 35)
The DCS230T and DCS232T come with an inertia chain
brake as standard equipment. If kickback 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 immediately 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) (Fig. 36)
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.
Fuel (Fig. 37)
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 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.
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 i.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
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. 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 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!
ALWAYS release the chain brake
before starting the work!
