BCleaning Air Cleaner Element [Single
Element Type]
1. Remove the element.
2. Clean the element:
(1) When dry dust adheres to the element, blow
compressed air from the inside, turning the
element. Pressure of compressed air must be
under 205 kPa (2.1 kgf/cm , 30 psi).
(2) When carbon or oil adheres to the element, soak
the element in detergent for 15 minutes then wash
it several times in water, rinse with clean water
and dry it naturally. After element is fully dried,
inspect inside of the element with a light and
check if it is damaged or not. (referring to the
instructions on the label attached to the case.)
3. Replace air cleaner element:
Once yearly or after every sixth cleaning, whichever
comes first.
A Check to see if the evacuator valve is blocked with
dust.

rear) upright. If the cover is improperly fitted, dust
passed by the baffle and directly adheres to the
element.
C Evacuator Valve
Open the evacuator valve once a week under ordinary
conditions - or daily when used in a dusty place - to get rid
of large particles of dust and dirt.
BCleaning Fuel Filter
This job should not be done in the field, but in a clean
place.
1. Loosen and remove the filter bowl, and rinse the inside
with kerosene.
2. Take out the element and dip it in the kerosene to
rinse.
3. After cleaning, reassemble the fuel filter, keeping out
dust and dirt.
4. Bleed the fuel system.
(See "SERVICE AS REQUIRED" in "PERIODIC
SERVICE" section.)
A When the fuel filter bowl has been removed, fuel stops
flowing from the fuel tank. If the fuel tank is almost full,
however, the fuel will flow back from the fuel return
pipe to the fuel filter. Before checking, make sure the
fuel tank is less than half-full.
