• Do not tilt the machine onto its side to the point where fuel leaks from the fuel tank cap.

• Do not crank the engine without spark plug.

2.4 MAINTENANCE, STORAGE

AND TRANSPORT Servicing the machine on a regular basis and correct storage maintain machine safety. Broken or worn parts must be replaced and never repaired. Only use original parts: using parts that are not original or installed incorrectly aects machine safety, and can therefore cause accidents or personal injury and relieve the Manufacturer of all obligations and liability. Maintenance

• If the tank can be emptied, perform this operation outdoors and when the motor is cold.

• To reduce the risk of re, check for oil and/or fuel leaks on a regular basis.3 Storage

• Never leave fuel in the tank if the machine is stored in a building where the fuel vapours can come into contact with open ames, sparks or sources of heat.

• Let the machine cool down before storing it indoors. Transport

• Transport the machine with an empty tank.

2.5 ENVIRONMENTAL PROTECTION

Protecting the environment must be a signicant and top priority for machine use, to the benet of civil co-habitation and of the environment that we live in.

• Avoid being an element of disturbance to the surrounding area.

• Adhere strictly to the local regulations governing the disposal of packaging, oil, fuel, lters, damaged parts or any other element which may have an impact on the environment; this waste must not be disposed of with regular waste, but must be separated and taken to collection centres, which will recycle the materials.

• When the machine is withdrawn from service, do not dispose of it in the environment, but take it to a waste disposal facility in accordance with the local regulations in force.

The combustion process generates toxic substances such as carbon monoxide, nitrogen oxides and hydrocarbons. It is important to control these substances because they can react with photochemical smog as well as with direct exposure to sunlight. Carbon monoxide does not react in the same way to exposure to sunlight but it must still be considered toxic. Our machines are equipped with emission reduction systems for the substances mentioned above.

3. ABOUT THE MACHINE

This machine is a spark-ignition engine. Engine performance, reliability and life are inuenced by many factors, some external and some strictly associated with the quality of the employed products and with the scheduled maintenance. Additional information is provided below for greater awareness of your machine. Any other use that does not comply with the above, can be dangerous and cause damage to people and/or property. IMPORTANT Improper use of the machine will void the warranty and relieves the Manufacturer of any liability, placing all responsibility for damage or injury, to him/ herself or third parties, on the user.

This machine is intended for use by consumers, i.e. non-professional operators. It is intended for "hobby-related activities".

There are various symbols on the machine. Their function is to remind the operator of the correct conduct for use, with due care and caution. Meanings of the symbols: WARNING! The silencer may become very hot. Do not touch it. WARNING! Top up with oil as far as the "MAX" level. Do not top up above the "MAX" level.

3.3 IDENTIFICATION LABEL

Write the serial number (S/n) of your machine on the space provided on the label at the back of the cover.

3.4 ENGINE COMPONENTS

The machine is comprised of the following main parts (g. 1 ). A. Oil ller cap with dipstick B. Oil drain extension C. Carburettor D. Air lter cover E. Spark plug cap F. Engine code

3.5 ENVIRONMENTAL CONDITIONS

The operation of a four-stroke endothermic engine is aected by: a) Temperature:

1. When operating at low temperatures

cold starts may be dicult.4

2. When operating at very high temperatures

warm starts may be dicult due to evaporation of the fuel in the oat chamber of the carburettor or in the pump.

3. In any case the right kind of oil

must be used, according to the operating temperatures. b) Altitude:

4. The higher the altitude above sea level,

the lower the max power developed by an endothermic engine.

5. When there is a considerable

increase in altitude, the load on the machine should be reduced and particularly heavy work avoided.

A good quality fuel is the major issue for the engine reliability of operation. Fuel must meet these requirements: a) Use clean, fresh unleaded gasoline, with a minimum of 90 octane b) Do not use fuel formulated with more than 10% ethanol. c) Do not add oil d) To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. Use of unapproved fuels will cause damage to engine components, which will not be covered under warranty. NOTE Only use the fuel named in the technical data table. Do not use other types of fuel. It is possible to use ecological fuels, such as alkylate petrol. The composition of this petrol has less of an impact on people and animals. No negative eects have been reported in connection to their use. Nonetheless, there are types of alkylate petrol on the market for which it is not possible to provide specic indications on their use.

Use always high quality oils, choosing their viscosity grade according to the operating temperature.

• Only use detergent oil with a quality of no less than SF-SG.

• Choose the SAE viscosity based on the technical data table.

• The use of multigrade oil can lead to greater consumption in hot weather, accordingly it is necessary to check the level more frequently.

• Do not mix oils of dierent brands and characteristics.

• SAE 30 oil, if used below +5°C, could result in possible engine damage due to inadequate lubrication.

The air lter must always be in perfect working order to prevent debris and dust from being sucked into the engine, thereby reducing the eciency and life of the machine.

• Always keep the ltering element free of debris and in perfect working order (par. 6.5).

• If necessary, replace the ltering element with an original spare part Incompatible ltering elements can impair the eciency and life of the engine.

• Never start the engine without mounting the ltering element properly.

Not all the spark plugs for endothermic engines are the same.

• Use only spark plugs of the recommended type, with the right heat range.

• Check the length of the thread, because - if too long - it will damage the engine beyond repair.

• Make sure that the electrodes are clean and that the air is correct (para 6.6).

Regulates the engine's r.p.m. The throttle control (usually a lever) mounted on the machine is connected to the engine by a cable. Refer to the owner’s manual to identify the accelerator lever and the its related positions, which are usually marked with symbols corresponding to:

• FAST= top speed; to be used during work.

Refer to the owner’s manual to identify the Choke command.5 It enriches the fuel/air ratio and should only be used momentarily to start the engine when cold.

Before every use, perform the following checking procedures in order to assure a regular operation.

5.1.1 Oil level check

6. Place the machine on a at surface.

7. Clean around the oil ll cap.

9. Remove the cap with the dipstick and

check the oil level that must be between the «MIN» and «MAX» marks.

10. If oil is required, add oil of the same kind

up to the «MAX» mark, being careful not to spill any outside the oil ll

11. Fully tighten the ller cap (g. 2.A)

and wipe o any spilled oil. NOTE Top up gradually, adding small amounts of oil, checking the level each time. Do not top up beyond the «MAX» level; an excessive level can cause:

• smoking from the exhaust;

• soiling of the spark plug or air lter with subsequent diculty for ignition. NOTE For the required type of oil, observe the indications provided in the technical data table.

5.1.2 Air lter control

The eciency of the air lter is essential to correct engine operation; do not start the engine if the lter element is missing or broken.
