PREPARING THE MIXTURE
WARNING! The engine works exclusively with an oil-petrol mixture
in the percentage 4% (advised to SYNTHETIC oil type JASO FC
GRADE or ISO EGC GRADE; it guarantees a better yield, a reduced
smokiness and a greater duration of the motor). If this mixture
is not used irreparable damage will be caused to the engine with
immediate loss of warranty.
WARNING! Risk of fire and explosion. The fuel and its fumes are
highly inflammable. Do not pour the fuel onto hot surfaces. Work
in a well ventilated area, do not smoke and keep away from naked
flames and incandescent objects. Use protective eyewear and anti-
acid heavy duty gloves. Do not swallow, do not inhale the fumes
given off by the fuel and keep it out of the reach of children. Avoid
contact with the skin. In case of contact with the eyes wash with
water and seek medical advice.
WARNING! Do not use the machine in areas with a risk of explosion
and/or fire, in indoor areas or in the presence of inflammable and/
or explosive liquids, gases, powders, vapours, acids or elements.
Do not use the machine in the presence of incendiary sources such
as naked flames, cigarettes, sparks, etc.
How to prepare a petrol-oil mixture
For the mixture use unleaded car petrol for (green or eurosuper) with
a minimum of 90 octanes and 100% synthetic oil for two-stroke
engines type JASO FC GRADE or ISO EGC GRADE.
Using a container and a measurer in a petrol-resistant container mix
40cc of oil for every 1000cc (1litre) of petrol. Shake the mixture well
before use. It is advisable only to prepare the quantity of mixture ne-
cessary for the task in hand. It is advisable to add specific additives
in order to prevent the mixture deteriorating over time. The storage of
the mixture for long periods without the addition of additives leads to
quick deterioration, with the consequent malfunctioning of the engine
and starting problems.
Keep fuels and the oil in homologated containers, away and out of
reach of children.
FILLING UP THE MACHINE (Fig. A)
IMPORTANT! Risk of fire and explosion. Refuel when the machine
is switched off. Let the machine cool before refuelling. If the fuel
has splashed onto the machine or floor, dry it up before starting
the machine.
WARNING! The engine works exclusively with an oil-petrol mixture
in the percentage indicated. If this mixture is not used as fuel the
engine will suffer irreparable damage with consequent immediate
loss of the warranty.
WARNING! Any refuelling must be carried out with the engine
switched off and the engine ignition switch in the "stop" position
(Fig.A, 25).
Before opening the petrol cap, for refuelling, place the chain saw
on a flat surface with the cap facing upwards. Open the cap (Fig.A,
14) by unscrewing it and fill up the tank without allowing it to
overflow and make sure the cap is firmly secured.
REFUELLING LUBRICATING OIL FOR THE CHAIN (Fig. A)
WARNING! Do not use old or recycled oil to fill the tank. Never use
the tool without oil as its functionality and the safety of the operator
would be compromised. The chain saw is sold with an empty tank.
Before opening the petrol cap, for refuelling, place the chain saw on
a flat surface with the cap facing upwards.
- Unscrew the oil cap (6) and fill the tank with biodegradable chain
oil available in specialized shops, hardware stores, agricultural
machinery dealers, etc.
- Fill the tank to a maximum of 1 cm below the cap, being careful not
to introduce dirt, sawdust, or dust inside.
- Close the tank cap.
- WARNING! It is very important to clean the chain saw (with a brush)
around the cap before refilling.
- IMPORTANT! The oil level must be checked frequently during use
to prevent the chain remaining without lubricant. Lack of lubricant
causes rapid wear of the chain and the bar. Top up the oil at least
every time refuelling is carried out.
- IMPORTANT! The length of time one oil fill-up lasts may vary
according to the chain tension, the type of wood being cut, the
environmental temperature, the oil density, and the usage of the
chain saw.
STARTING UP THE ENGINE
PLEASE NOTE! Before starting the engine make sure that the saw
is in perfect order, that the petrol and oil tanks are suitably full.
The machine has a centrifugal clutch (26) and with the engine at a
minimum (without acceleration) the chain does not turn. In order to
stop the cutting device rotation it is enough to release the accelerator
(4) so that the engine slows to minimum speed. The accelerator
control is equipped with a safety lock-off lever (5) that aims to block
involuntary starting of the chain.
WARNING! The chain could begin moving during start-up with a
cold engine. Use the accelerator control immediately to bring the
engine to minimum.
Cold engine start-up
1) Activate the fuel pump (32) until the carburettor has been fully
primed (when fuel appears in the pump).
2) Shift on/off switch (25) to the "I" ON position
3) Activate the chain break by pushing the hand guard (8) forward,
towards the bar (10).
4) Shift the air control (24) to the "close" position.
5) Place the chain saw on the floor in a firm position and carefully
check that the chain and the bar are far from any objects or people.
6) Keep it in position by securely gripping the front hand grip (Fig.
D). Make sure the chain is free.
7) Pull the start handle (9) a few times to trigger the feeding pump.
8) Bring the air control lever (24) to the "open" position and pull the
start handle firmly without releasing it with a jerk.
9) A few seconds after the engine has started, accelerate the machine
a few times by pressing the release lever 5 and the accelerator 4
at the same time to bring the engine to a minimum.10) With the
engine at minimum, deactivate the chain brake by pulling the hand
guard (8) backwards, towards the rear hand grip.
Hot engine start-up
1) Shift on/off switch (25) to the "I" ON position
2) Place the chain saw on the floor in a firm position and carefully
check that the chain and the bar are far from any objects or people.
3) Keep it in position by firmly gripping the front hand grip (Fig. D).
4) Pull the start handle firmly (9), to start the engine, without releasing
it with a jerk.
Please note: with the engine warm, don't use the air comand (24).
SWITCHING OFF THE ENGINE
1 Release the accelerator lever (4) so that the engine goes back to a
minimum and the chain stops.
2 Shift the engine off switch (25) to "O".
BREAKING IN THE ENGINE AND CHAIN
Do not use the chain saw on full load or for extended periods for the
first 20 hours of use and do not allow the machine to function idly at
full throttle. Check the chain tension often.
CARBURATION
Caution! For correct machine carburation, clean the air filter (fig.
A, 31) from dust/sawdust and oil regularly using the instructions
contained in the maintenance and cleaning chapter.
The carburation has already been correctly adjusted in the factory
and does not need to be set. In case of carburation faults, clean the
air filter or have the chain saw checked at a customer service centre.
Please note: The carburation can vary according to climatic conditions
and/or altitude.
The screws L, H, T act on the following parameters:
Screw L: It regulated the carburation of the minimum and must be
