without the specifications expressedly shown

in this manual, can cause serious damage to

the engine!

2. Prepare the mixture in a clean can, homologated for the

petrol. Prepare the mixture in an area without sources of

heat or sparks and well aired also.

To obtain the best mixture, pour the oil and then the petrol

in the container before. You avoid turning over the petrol.

Shake the can strongly ( repeat the operation every the

fuel is taken sometimes from the can ).

The characteristics of the mixture are subject to ageing

and therefore change over time. Therefore, we

recommend preparing only the quantity necessary for use.

Beware of using a mixture several weeks old; it could

damage the motor.

REFUELING

ATTENTION! The following precautions

decrease the risk of fire:

• Ensure maximum ventilation.

• Do not smoke or bring sources of heat or

sparks near fuel.

• Always refuel with the motor turned off.

• Open the petrol cap with caution, to remove

possible excessive pressure.

• Do not remove the petrol cap with the motor

running.

• Tightly screw the cap back on after refuelling.

• Move the saw before starting it up.

Always conduct refuelling in a well-ventilated area.

3. Position the saw on a flat, solid surface, so that it can’t fall

over and the petrol caps are turned upward.

To avoid impurities entering, carefully clean the inside of

the tank supply pipe union before removing the cap. Open

the tap of the tank with caution. Unscrew the cap of the

tank containing the mixture and fill it with the necessary

amount with the help of a funnel. Avoid turning over the

fuel. Once the tank is filled, close the cap tightly.

ATTENTION! If you have spilled fuel, dry the

saw well. If you have spilled some fuel on your-

self, change clothes immediately.

Avoid contact with skin or eyes.

ATTENTION! The silencer is very hot during use

and soon after the stop of the engine, even if

the motor was on minimum. Pay careful atten-

tion to the risk of fire especially in the presence

flammable gasses or materials.

Always check that there are no fuel losses.

CONSERVATION OF FUEL

The petrol is highly flammable. Keep it in a cool, well-aired

environment stored in a container homologated for this

purpose. Never leave the saw idle with fuel in the tank if the

environment is not ventilated or where the gas produced by

the petrol could reach flames, candles, burners, boilers,

switches, al machines, water heaters, dryers etc. The gas

produced by combustible items can cause explosions or fires.

Never keep or store excessive amounts of fuel.

LUBRICATION OF THE CUTTING EQUIPMENT

ATTENTION! Lubrication of the cutting equip-

ment. Insufficient lubrication of the cutting

equipment also causes the chain to break with

heavy risk of serious or fatal personal injury.

The lubrication of the chain is insured by an automatic pump.

The mechanical oil pump for chain lubrication can be

adjusted.

The feed rate of the chain oil pump can be adjusted by means

of the regulating screw (see details in the illustration).

Chain oil

It’s recommended you use new oil (special type) with good

viscosity. The oil for the cutting chain must offer good

adhesion to the chain and good flowing properties, both in

summer and winter.

Where oil for chains is not available use oil for EP 90

transmissions. Never use exhausted oils. These oils are

harmful to you, the saw and the environment. It is important

to use opportune oil for the temperature of the air (correct

viscosity). With temperatures lower than 0 ° some oils get

denser, overload the pump and damage it. For the choice of

the oil contact the service workshop.

Supplying the chain oil

4. Unscrew the cap of the chain oil tank. Fill the tank avoiding

the spilling of any oil; if this occurs clean the saw well.

Screw the cap back on and check there are no losses. Top

it off with every supply opportunity.

ATTENTION! In the event of prolonged storage,

empty and clean the fuel and chain oil tank.

Contact the nearest supply station for the dis-

posal of the excess fuel and oil.

F. Starting and stopping

ATTENTION!

• Never start the saw without mounting the chain and the Carter clutch cover.

The clutch could come off and injure the operator.

• Always move the saw away from the supply area before starting it up.

• Assume a stable position and check that the chain can turn freely.

• Check there are no other people in the work vicinity.
