ends on the palm of the hand (Fig. 26).
DO NOT tap the element against a hard
surface as it will become damaged or
distorted.
3. Alternatively, to remove dust, com-
pressed air (Fig. 27), not exceeding 7
bar (100 lbf/in2) may be used. Insert
the air line nozzle inside the element
and blow the dust from the inside to
the outside. Blow loose particles from
the outside of the element by holding
the nozzle at least 300 mm (12 in)
from the element. Protect your eyes
when carrying out this operation.
4. Clean the inside of the air cleaner cas-
ing with a damp lint-free cloth and re-
fit the outer element ensuring that the
rubber sealing ring (4) on the end is
secure.
5. If the warning light comes on after a
very short interval of time, the main
element is unfit for service and must
be replaced. However, if after replace-
ment of the main element, the warning
light stays on, the inner secondary ele-
ment must also be replaced – DO NOT
attempt to clean it.
Inner secondary element
Change every third service
The inner filter element (Fig. 25) is
a secondary filter to protect the engine
should harmful particles pass through the
main filter. This inner element should be
changed every third time the main filter is
cleaned or replaced. DO NOT attempt to
clean the inner secondary element.
