• Let the machine cool down before storing it indoors.

3.1 MACHINE DESCRIPTION

AND INTENDED USE

This machine is a spark-ignition engine Engine performance, reliability and life are influenced 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 causes the warranty to lapse and relieves the Manufacturer of any liability, placing all responsibility for damage or injury, to him/ herself or third parties, on the user. Transport

• Transport the machine with an empty tank.

2.5 ENVIRONMENTAL PROTECTION

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

• Avoid being an element of disturbance to the surrounding area.
• Follow local regulations closely for the disposal of packaging, oils, fuels, filters, worn parts or any element that strongly impacts the environment; this waste must not be disposed of with regular waste, but must be separated and taken to collection centres, who will recycle the materials.
• At the time of decommissioning, do not leave the machine in the environment, rather, contact a collection centre, in accordance with local regulations in force.

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

3.2 SAFETY SIGNS

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: ATTENTION! The muffler may be very hot. Do not touch.

2.6 EMISSIONS

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. Write the serial number (S7n) 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 (fig. 1). A. Oil fillercap with dipstick B. Carburettor C. Air filter cover D. Spark plug cap E. Engine code

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

3.5 ENVIRONMENTAL CONDITIONS

The operation of a four-stroke endothermic engine is affected by: a) Temperature: –– When operating at low temperatures cold starts may be difficult. –– When operating at very high temperatures warm starts may be difficult due to evaporation of the fuel in the float chamber of the carburettor or in the pump. –– In any case the right kind of oil must be used, according to the operating temperatures.

3.8 AIR FILTER

The air filter must always be in perfect working order, to prevent debris and dust from getting sucked into the engine, reducing the efficiency and life of the machine.

• Always keep the filtering element free of debris and in perfect working order (par. 6.5).
• If necessary, replace the filtering element with an original spare part. Incompatible filtering elements can impair the efficiency and life of the engine.
• Never start the engine without mounting the filtering element properly. b) Altitude: –– The higher the altitude above sea level, the lower the max power developed by an endothermic engine. –– When there is a considerable increase in altitude, the load on the machine should be reduced and particularly heavy work avoided.

3.6 FUEL

A good quality fuel is the major issue for the engine reliability of operation.

3.9 SPARK PLUG

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 their gap is correct (par. 6.6). Fuel must meet these requirements: a) Use clean, fresh unleaded gasoline, with a minimum of 90 octane. b) Do not use fuel formulated with ethanol greater than 10%. c) Do not add oil. d) To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel.

4. CONTROLS

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 effects 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 specific indications on their use. This controls engine rpm. The throttle trigger (generally a lever), fitted to the machine, is connected to the engine by a cable. Consult the machine's Instructions Manual to identify the throttle trigger and its positions, usually marked by symbols, corresponding to:

• FAST = corresponds to maximum revs; to be used when working.
• SLOW = corresponds to minimum revs.
• CHOKE = to be used for cold starts (when applicable)

3.7 OIL

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

1. Unscrew the fuel cap and take it off.

2. Set a funnel on the hole.

3. Refuel and take the funnel off.

4. At the end of refuelling, screw the cap

back on and clean any spillage. IMPORTANT Avoid getting fuel on the plastic parts of the engine or machine to avoid damaging them, and immediately clean off every trace of spilled fuel. The warranty does not cover damage to plastic parts caused by fuel.

5. REGULATIONS FOR USE

5.1 BEFORE EACH USE

Before every use, perform the following checking procedures in order to assure a regular operation. The fuel characteristics are provided in the specific paragraph (see 4.2 and 8.1).

1. Place the machine on a flat surface.
