CAUTION:

- Match your fuel purchases to your consumption; don’t buy more than you will use in one or two months;

- Store gasoline in a tightly-closed container in a cool, dry place.



CAUTION - For the mixture, never use a

fuel with an ethanol percentage higher than 10%; gasohol (mixture of gasoline and ethanol) up to 10% ethanol or E10 fuel are acceptable.

When using an Oxygenated Gasoline a good practice of Fuel Management is necessary. Gasoline Oxygenated with alcohol readily takes/ up water when it is present; the water may be condensed out of humid air or be a contaminant in the fuel system, including tank. The use of Oxygenated Gasoline may cause the occurrence of vapor-lock easier.

NOTE - Prepare only the quantity of mixture required for immediate use; do not leave fuel in the tank or a container for a long time. Were commend the use of the additive if the mixture is to be stored for 12 months.

Alkylate gasoline



CAUTIONS – Alkylate fuels have different

density than normal fuel. Therefore engines, set with normal fuel, need different H jet regulation to avoid critical issues. For this operation it’s necessary turned at a Licensed Service Dealer.

FILLING THE TANK

Stir the mixture well before refuelling.

If you are using a petrol can to prepare the mixture, make sure the container is clean and mix for at least a minute to ensure the oil is properly dissolved in the petrol. The oil percentages are shown in the tables below.



WARNING: Follow safety instruction for

fuel handling. Always shut off engine before fuelling. Never add fuel to a machine with a running or hot engine. Move at least 3 m from refuelling site before starting engine. DO NOT SMOKE!

1. Clean surface around fuel cap to prevent contamination.

2. Loosen fuel cap slowly.

3. Carefully pour fuel mixture into the tank. Avoid spillage.

4. Prior to replacing the fuel cap, clean and inspect the gasket.

5. Immediately replace fuel cap and hand tighten. Wipe up any fuel spillage.

NOTE: It is normal for smoke to be emitted from a new engine during and after first use.



WARNING: Check for fuel leaks, if any are found, correct before use. Contact a

Servicing Dealer if necessary.

ENGINE

Clean cylinder ns with a brush or compressed air periodically. Dangerous overheating of engine may occur due to impurities on the cylinder.

SPARK PLUG

Clean spark plug and check electrode distance periodically (Fig. 16). Use Champion RCJ6Y or of other brand with the same thermal grade.

FAN CASING

Following prolonged use of the blower a large amount of dust may be deposited on the fan casing (behind the cushion). This obstructs the air ow (reduced volume) and can result in damage to the fan and/or overheating of the engine. For this reason, be sure to clean the fan casing regularly. Clean the slots in the fan casing: they play an important role in relation to engine cooling.

CARBURETOR

The carburettor is factory adjusted to standard settings that comply with emissions regulations.

WARNING:

- Do not change the carburettor settings by tightening or loosening the regulator screws; this operation must be performed by qualied personnel at an Authorized Service Centre.

- Incorrect adjustment of the carburettor can cause serious damage to the engine.

- Furthermore, do not tamper with or remove the red protective caps on the carburettor regulator screws.

In the case of problems (engine dies when idling, irregular engine speed or failure to reach maximum power) seek the assistance of an Authorized Service Centre.

WARNING: Weather conditions and

altitude may aect carburation.
