MAINTENANCE
SERVICE PROCEDURE
WHEN REQUIRED
CHECK, CLEAN OR REPLACE AIR CLEANER
WARNING
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.
When using compressed air, there is danger that dirt may be blown around and cause serious injury.
Always use safety glasses, dust mask, and other protective equipment.
CHECKING
1. Check that the red line in the transparent portion of dust
indicator (1) does not indicate 0.0075 MPa (30 INCHES H
2
O)
(0.076 kgf/cm
2
, 1.1 PSI).
2. If the red line indicates 0.0075 MPa (30 INCHES H
2
O) (0.076
kgf/cm
2
, 1.1 PSI), clean or replace the air cleaner element
immediately.
3. After checking, cleaning, or replacing, press the top of dust
indicator (1) to return the red line to its original position.
NOTICE
Do not clean the element until the dust indicator shows 0.0075 MPa (30 INCHES H
2
O) (0.076 kgf/cm
2
, 1.1 PSI).
If the element is cleaned frequently before the dust indicator shows 0.0075 MPa (30 INCHES H
2
O) (0.076 kgf/cm
2
, 1.1 PSI), the
air cleaner will not be able to display its basic performance fully, and the cleaning efficiency will also go down. In addition,
during the cleaning operation, more dirt stuck to the element will fall inside the inner element.
If the pressure rises to 0.005 MPa (20 INCHES H
2
O) (0.051 kgf/cm
2
, 0.7 PSI) immediately after it is cleaned, replace the air cleaner
elements (outer element and inner element). Even if the rise in pressure is slow, replace the air cleaner element once a year.
