Cleaning the air filter
(Refers to FPT components)
Only proceed with the engine stopped.
q Remove the filter cover (1) after first unscrewing the locking
handle.
q Remove the external cartridge (2), after unfastening the second
locking handle; during this operation, take care to ensure that no
dust get into the sleeve.
q Check that there is no dirt. If there is, clean the filter element as
indicated below.
q Blow dry compressed air through the filter element, from the inside
outward (maximum pressure 200 kPa). Do not use detergents; do
not use diesel.
q Never use tools to beat the filter element, and check its condition
before replacing it.
q Replace the filter if any breakages or tears are found.
q Check that the gasket at its base is in good condition. Some filter
systems are fitted with a second filter element (3) which does not
require cleaning; this must be replaced at least once every 3
changes in the main element.
q Reassemble by repeating the above operations in reverse order.
q Set up the mechanical blockage indicator for operation by pressing
the button located on the top part of the indicator. This operation is
not necessary if there is an electrical sensor.
WARNING
Take care to ensure that the parts are reassembled correctly.
Imperfect assembly might result in unfiltered air being sucked into the
engine, causing serious damage.
