1. CHECKS DURING WORK
• Checking the chain tension
The chain tends to stretch gradually as you work,
so you need to check its tension frequently.
IMPORTANT
(or after replacing the chain), it must be checked
more frequently due to settling of the chain.
WARNING!
loose, as it can be hazardous if the chain slips
out of its guides.
To adjust the chain tension, follow the instructions
in Chapter 5.5.
• Checking the oil delivery
IMPORTANT
out lubrication! The oil tank may get almost empty
every time the fuel runs out. Make sure you top up
the oil tank every time you refuel the chain-saw.
WARNING!
chain are in place when you check the oil de-
livery.
Start the engine, keep it running at medium power
and check if the chain oil is delivered as shown in
the figure (Fig. 11).
You can adjust the chain oil flow using a screw-
driver on the adjuster screw (1 or 1a) of the oiler,
which is on the bottom of the machine (Fig. 11).
2. DIRECTIONS FOR USE AND CUTTING
TECHNIQUES
Before felling or delimbing for the first time, practise
sawing logs on the ground or on trestles, so that
you can get familiar with the machine and the most
suitable sawing techniques.
WARNING!
ately if the chain stops during sawing. Bewa-
re of kickback, which can occur if the bar con-
tacts an obstacle.

Kickback occurs when the tip of the chain co-
mes in contact with an object or when the
wood contracts and jams the chain during sa-
wing.
This contact with the tip of the chain can cau-
se a rapid backward motion, pushing the gui-
de bar up and towards the operator. This also
happens when the chain is jammed along the
upper part of the bar. In both cases, kickback
can cause the operator to lose control of the
chain-saw, leading to serious consequences.
WARNING!
• Before proceeding to your job, read the sec-
tion "For Safe Operation". It is recom-
mended to first practice sawing easy logs.
This also helps you get accustomed to your
unit.
• Always follow the safety regulations. The
chain saw must only be used for cutting
wood. It is forbidden to cut other types of
material. Vibrations and kickback vary with
different materials and the requirements of
the safety regulations would not be respec-
ted. Do not use the chain saw as a lever for
lifting, moving or splitting objects. Do not
lock it over fixed stands. It is forbidden to
hitch tools or applications to the PTO other
than those specified by the manufacturer.
• It is not necessary to force the saw into the
cut. Apply only light pressure while running
the engine at full throttle.
• When the saw chain is caught in the cut, do
not attempt to pull it out by force, but use a
wedge or a lever to open the way.
• If there is a barrier between the piece to be
cut and the chain-saw, turn off the chain-saw
and wait until it stops completely. Wear pro-
tective gloves and remove the obstacle. If
the chain must be removed, follow the in-
structions in the chapter dedicated to chain-
saw assembly. A test run must be done after
having removed the obstacle and reassem-
bled the chain. If you notice vibrations or
mechanical noises, stop working and con-
tact your dealer.
• Using the spiked bumper (if provided)
(Fig. 12)
1. Dig the spiked bumper into the log and use it as
a pivot. Cut with an arched motion to make the
bar penetrate the wood.
2. Repeat several times if necessary, changing
the point where you plant the spiked bumper.
