AIR INTAKE SYSTEM
The air filter element 1 should only be cleaned when
there is an alarm on the InfoViewt monitor
"Air filter blocked" (625 mm) (24 - 5/8") vacuum.
To remove the air filter element, remove cover 2 by
loosening clamps 3.
To clean the element, hold the top and tap it against
the palm of the other hand to remove the dust.
NEVER TAP IT ON A HARD SURFACE.
When tapping does not remove the dirt, direct
compressed air through the element, from the inside
towards the outside.
To prevent damage to the element when cleaning
with compressed air, take the following precautions:
• Maximum air pressure must be 5 bar (72,5 psi).
Move the nozzle up and down when rotating the
•
element.
• Keep the nozzle at least 25 mm (1") from the
plated paper.
NOTE: To keep the interval acceptable is it highly
recommended to clean the element with compressed
air.
WARNING
Wear a dust mask when cleaning the air filter
element.
If the element is soiled with oil or soot, it is possible
to soak it for 15 minutes in a solution of 75 grammes
(0,165 lbs.) of non-sudsy detergent and 10 litres
(2,6 US gal) of lukewarm water.
Rinse the element thoroughly in clean water until the
water remains clear and leave the element to dry.
NEVER WASH THE AIR FILTER ELEMENT IN
PETROL OR DIESEL OIL.
