AIR CLEANER TYPE 203
Element Base
Filter Element
End Plate
Retaining Screw
203 Intake Elbow
"O" Ring
NOTE:
The element is already impregnated with a special

handling it, to prevent dust or dirt from adhering to
the element. If your fingers become contaminated,
wash them with soap and water.

ASSEMBLY
Fit the end plate, retaining screw, making sure that
the element fits correctly between the end plate and
base.
This is a heavy-duty wet type air cleaner that has
been developed specifically for 3.5cc 'off-road'
model car engines. It is more compact than the
former O.S. SUPER AIR CLEANER 202 and this
makes it easier to install within a car body.
Insert the filter element on the element base.
Fit the end plate with retaining screw, making sure
that the element fits correctly between the end
plate and base.
Insert the joint pipe on the element base and
secure it with "O" ring.

FURTHER PRECAUTIONS
When removing the air cleaner, check the inside of the
element base and carburetor venturi. If any dirt is
detected, this indicates that the filter element was
incorrectly fitted or should have been replaced earlier.
In this event, it is vitally important to wash out the inside
of the engine thoroughly, with alcohol or fuel, before it
is used again, otherwise rapid wear of the
piston/cylinder assenbly, bearings, connecting-rod,
etc., will occur. Obviously, it will be necessary to carry
out the same procedure with the air cleaner and to
replace the filter element.
NOTE:
Be careful not to splash alcohol or fuel over the
filter element, or the filter oil will be washed away,
and the filter capacity will be lowered.
It is advisable to replace the filter element after each
hour of running time. Be careful not to enter the dirt
and dust into the carburetor.
REPLACMENT OF ELEMENT
INSTALLATION
During storage, the oil may have become unevenly
dispersed through the element. This will be
indicated if the blue colour of the element material
appears patchy. In this case, place the element in a
small plastic bag and gently rub the element
between finger and thumb to redistribute oil.
Carefully clean the carburettor, removing any old
adhesive or sealant that may have been previously
used on the outside of the air intake.
