OPERATION No. 18
Changing filtering element of the preliminary filter and fuel purifying element
Service life of the filter element mostly depends on degree of purity of the fuel in use. In case there is a
suspicion, that the fuel is not clean enough, you must check the filter more often and replace the filter
element. Any time you change the fuel, in connection with the autumn-winter period or winter-spring period
(however at least each 200 mth), you must change the preliminary filter element and fuel purifying element
as well.
