tract the disassembled parts and accessories as
shown in Fig.2. In the box you will find:
part.1 – Chainsaw body

make sure that the (chain) safety brake is not ingaged
(arrow Fig.3).
3) Unscrew the nuts (Fig.4 part.1) and remove the
brake cover.
4) Rotate the chain tensioning screw anticlockwise
(unscrew direction) (Fig.5 part.1) so that the chain
tensioning tooth retreats (Fig.5 part.2).
5) Fit the chain around the drive sproket fig 6.
The teeth of the top part must be oriented as shown
in the diagram.
ATTENTION !! Make sure to match the chain teeth
correctly with the corresponding sprocket teeth.
6) Position the chain guide bar on the stud bolts
(Fig.7).

8) Slightly screw up (clockwise) the chain tension
screw to achieve initial light tension (fig. 9).
9) Fit the chain cover back on and tighten the nuts
by hand.
10) Complete chain tensioning by screwing up
(clockwise) the chain tension screw (fig. 9).
When the proper tension has been reached, the
chain can be raised with two fingers to the point
where an entire guide tooth is visible (Fig.9 part. A).
11) Fully tighten the two nuts with the key provided
(Fig.10) keeping the point of the bar raised. Check
that the chain can run freely in the bar.
NOTE!! The tension of a new chain must be checked
and set (with the engine off and the brake on) after
a few minutes of work.
5. REFUELLING
1) ATTENTION! The equipment
is provided with a 2-stroke en-
gine.
The engine requires a mixture of petrol and oil for
2-stroke engines with the following percentages.
40:1 = (2,5% oil)

RECOMMENDED OIL

Top-quality oil for two-stroke engines:
Service class JASO: FC class
2) Mix by shaking the fuel container extensively
before each refuelling.
3) Prepare the fuel mixture and perform the refuel-
ling only in the open air (Fig.23).
4) Store the fuel in a container made for the pur-
pose and with the cap properly closed.
Top up the chain oil tank every time you
add fuel.
