Ruggerini RY 125 Use & Maintenance page 25

• Before carrying out any work on the engine, turn it off
and allow it to cool down. Do not perform any
operation while the engine is running.
• The liquid cooling circuit is under pressure. Do not
carry out any checks before the engine has cooled
down, and even then open the radiator cap or the
expansion tank cautiously. Wear protective clothing
and glasses. lf there is an electric fan, do not approach
the engine while it is still hot as the fan may come on
even when the engine is not running. Clean the
cooling system with the engine turned off.
• While cleaning the oil bath air filter, check that the oil
is disposed of in such a way as not to harm the
environment. Any filtering sponges in the oil bath air
filter should not be soaked with oil. The cyclone pre-
filter cup must not be filled with oil.
• Since the oil must be emptied out while the engine is
still hot (approx. 80°C), particular care should be
taken in order to avoid burns. In any case make sure
that oil does not come into contact with your skin
because of the health hazards involved.
• Check that the discharged oil, the oil filter and the oil
contained in the oil filter are disposed of in such a
way as not to harm the environment.
• Close the fuel tank filler cap carefully after each
fílling operation. Do not fill the tank right up to the top,
but leave sufficient space to allow for any expansion
of the fuel.
• Fuel vapours are highly toxic, so fill up only in the
open air or in well ventilated environments.
• Do not smoke or use naked flames while filling.
• Take care when removing the oil filter as it may be
hot.
• The operations of checking, filling up and replacing
the cooling liquid must be carried out with the engine
turned off and cold. Take particular care if liquids
containing nitrites are mixed with others not containing
these compounds as this may give rise to the
formation of nitrosamines which are a health hazard.
The cooling liquid is polluting, so dispose of in a
manner that does not damage the environment.
• During operations which involve access to moving
parts of the engine and/or removal of the rotary
guards, disconnect and insulate the positive cable
of the battery so as to prevent accidental short
circuits and activation of the starter motor.
• Check the belt tension only when the engine is
turned off.
• In order to move the engine use exclusively the
eyebolts fitted for this purpose by Ruggerini. These
lifting points are however not suitable for the entire
machine, so in this case use the eyebolts fitted by
the manufacturer.
