AIR CLEANER CLEANING·INSPECTION
1. Open the engine hood.
2. Remove the element.
Note:
In case of the double element type (OPT), do not remove the
inner element for other than replacement.
3. Clean the element.
(1) For ordinary cleaning, blow with compressed air [690 kPa
(7 kgf/cm
2
) [100 psi] or less] vertically along the pleats
from the inside of the element.
If heavily contaminated, washing is possible.
(2) Element washing method
Dissolve neutral detergent in tepid water (approx. 40°C
(104°F)) and immerse the element in it for about 30
minutes. Then, rinse the element well with clear water.
[Water pressure: 275 kPa (2.8 kgf/cm
2
) [40 psi] or less]
After washing, naturally dry the element or dry the
element with a dryer (cold air).
Note:
• Do not damage the paper filter during washing.
• Never use compressed air or hot air for drying.
4. Clean the evacuator valve (dust discharge valve).
Hold the tip end of the evacuator valve and discharge dust and
dirt from the inside of the valve.
5. Inspect the element.
After cleaning, place an electric bulb in the element to inspect
any damage in the element. If any pinhole, tear or damage is
found, replace it with a new element.
6. Element replacement
Replace the element after it is washed six times or generally at
intervals of 12 months.
