Pull back the hand guard to release the chain brake.
f
Remove the clutch cover (Fig. 2.12).
f
Fit the chain on the chain sprocket teeth with the
f
cutters facing in front and drive the chain into the
groove of the bar and around its nose (Fig. 3).
The bar must be pulled forward until the chain is well
f
fitted on the bar (Fig. 5).
Put back to its position the clutch cover and pay spe-
f
cial attention in order to fit correctly the chain ten-
sioner pin, inside the specified mounting point (hole)
of the bar (Fig. 7).
Place back the nuts to the clutch cover, but not screw
f
them up to their final position (Fig. 8).
Use a screw driver to adjust the chain tension proper-
f
ly, using the tension screw (Fig. 8).
Pull the bar nose up, check once again the chain ten-
f
sion and screw the nuts of the clutch cover.
The chain is correctly tensioned when there is no
slack on the underside (Fig. 4) of the bar and it can
be turned freely by hand. When fitting the chain,
the chain tension must be checked frequently. A
correctly tensioned and sharpened chain ensures
good cutting performance and long life.
Note: A new chain is being stretched after approx-
imately 5 cuts and need to be readjusted.
FUELING AND LUBRICATION
The chainsaw is equipped with 2-stroke engine;
therefore, oil mixture of petrol 95 RON and
2-stroke oil, must always being used. It is very
important to pay attention with the fuel mixture
that you use, since accurate mixture of oil and fuel
must be obtained. Small quantities of oil and fuel
mixture with small inaccuracies, can affect the ra-
tio of mixture, which may lead to engine overheat
and serious damages in the engine. Mixture with
fuel of higher Octane is only recommended to be
used, when working continuously at high revs.
Two stroke oil
Especially formulated 2-stroke oil for air cooled
2-stroke engines must be used. Do not use 2-stroke
oil intended for water cooled engines use. Never
use poor quality of oil and 4-stroke engine oil.
Mixing ratio
For best results and performance, the mixing ra-
tio is 1:33 (3%) with oil class JASO FB or ISO EGB,
formulated for air cooled 2-stroke engines.

Always use clean container for fuel before mixing
the fuel. Mix and shake the fuel mixture thorough-
ly, before filling the machine's fuel tank. Do not
use fuel mixture stored for more than a month.
The fuel tank of the machine must be emptied
before storage.
Chain oil
Use special chain oil with good adhesion charac-
teristics. Waste engine oil must never being used,

(1:33)

since it can be dangerous for the user and can lead
to the oil pump damage. The chainsaw has been
designed in such a way, where the oil tank must be
filled up every time the fuel tank is getting empty.
Note: Always switch the engine off and let it cool
down, before refueling. Never smoke during the
refueling process.
Note: Never operate the chainsaw with 100% of
petrol, without adding 2-stroke oil.
