CHECK, CLEAN AND REPLACE AIR CLEANER ELEMENT 4
WARNING
q
If inspection, cleaning, or maintenance is carried out with the engine running, dirt will get into the
engine and damage it. Always stop the engine before carrying out these operations.
q
When using compressed air, there is danger that dirt may be blown around and cause serious injury.
Always use protective glasses, dust mask, and other protective equipment.
CHECKING
If the yellow piston at the display portion of dust indicator (1)
becomes red (7.5 kPa), clean the outer element.
NOTICE
Do not clean the filter element until after a yellow piston in
the dust indicator display has come in the red area (7.5
kPa).
If the filter element is cleaned frequently before the yellow
piston in the dust indicator display comes in the red area
(7.5 kPa), the air cleaner cannot exert its inherent cleaning
capability, reducing its cleaning effect.
In addition, dust sticking to the element falls into the inner
element each time the element is cleaned.
CLEANING OR REPLACING OUTER ELEMENT
1. Open the left engine side cover.
2. Remove three clips (2), then remove cover (3).
NOTICE
Never remove inner element (5). If it is removed, dust will
enter and cause engine trouble.
3. Remove outer element (4).
