replacement.

The maintenance operations listed above refer to an engine operating in normal conditions (temperature, degree of humidity,

dust in the working environment). They may vary significantly according to the type of use.

Danger

• To avoid explosions or fire outbreaks, do not smoke or use naked flames during the operations.

• Fuel vapours are highly toxic. Only carry out the operations outdoors or in a well ventilated place.

• Keep your face well away from the plug to prevent harmful vapours from being inhaled. Dispose of fuel in the correct way and

do not litter as it is highly polluting.

FUEL

When refuelling, it is advisable to use a funnel to prevent fuel from spilling out. The fuel should also be filtered to prevent dust or

dirt from entering the tank.

Use the same type of diesel fuel as used in cars. Use of other types of fuel could damage the engine. The cetane rating of the

fuel must be higher than 45 to prevent difficult starting. Do not use dirty diesel fuel or mixtures of diesel fuel and water since this

would cause serious engine faults.

The capacity of the standard tank is: lt. 4,0
