CATALYTIC SILENCER
The catalytic version of the MX50 is fitted with a silencer with metal catalytic converter of the "plati-
num-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 diox-
ide 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 ex-
haust 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.
