To have the catalytic converter functioning correctly for long periods and to reduce possible

problems regarding the contamination of the thermal unit and of the exhaust, it is necessary to

avoid covering long distances with the engine running at constantly low rpm.

It is sufficient to alternate these periods with periods in which the engine runs at relatively high rpm,

even if only for a few seconds, but rather frequently.

What has been stated above assumes particular importance for the cold starting of the engine: in this

case, in order to reach a rpm regime sufficient to enable the “priming” of the catalytic reaction, you just

need to make sure that the temperature of the thermal unit has reached at least 50°C, which generally

occurs a few seconds after starting the engine.

The catalytic version of the RX50 is fitted with a silencer with metal catalytic converter of the “platinum-

rhodium bivalent” type. This device provides for the oxidation of the CO (carbon monoxide) and of the

HC (unburned hydrocarbons) contained in the exhaust gases, changing them into carbon dioxide and

steam, respectively. Due to the catalytic reaction, the high temperature reached by the exhaust gases

results in the burning of the oil particles, thus keeping the silencer clean and eliminating the exhaust

fumes.

Avoid parking the catalytic vehicle near dry brush wood or in places easily accessible to chil-

dren, as the catalytic silencer becomes extremely hot during use; be very careful and avoid any

kind of contact before it has completely cooled down.

Maximum front and rear pressure: ,5 bar

Low pressure can cause handling prob-

lems and the tendency to weave and in

extreme cases loss of control.

Moreover this will cause a great increase of roll-

ing friction.

The results are: high consumption of fuel and re-

duced maximum speed.

The disadvantage may cause a damage of the cover,

due to excessive local deformation.

Tyre pressure must be checked when the

tyres are at environment temperature,

that is, when the vehicle has not been moved in

the last or 3 hours for more than 1 km.

Check the depth of the tyre tread often, if

it is worn below the allowable limit ( -

3 mm.) change the tyre.

– The tyre should often be inspected for signs of

damage or cuts.

– Blowings or irregular wavings are showing in-

ternal damages, which request the prompt re-

placement of the tyre.

Remember: 1 mile = 1.6 km

1 km = 0.6 5 miles

It is a good rule to write down the frame and engine

numbers in the space provided in this manual.

The frame number can be used for the purchase of

spare parts.

Do not alter the identification numbers if

you do not want to incur severe penal and

administrative sanctions. In particular, the altera-

tion of the frame number results in the immediate

invalidity of the guarantee.
