MAINTENANCE PROCEDURES

4.9.1.b CAB AIR FILTER CHECK AND CLEANING (machines with cab)
WARNING
q
To carry out this maintenance operation it is necessary to tilt the cab floor. Carefully follow the instruc-
tions given in paragraph "3.2.9 TILTING THE CAB FLOOR" or have this operation carried out by your Ko-
matsu Dealer.
q
Wear safety goggles during the cleaning operations.
Air intake through the cab ventilation is protected by a filter locat-
ed on the right side of the cab.
The filter retains all the air impurities and is cleaned every time air
circulation is reduced.
The filter can be accessed from outside the cab after overturning
the platform (see "3.2.9 TILTING THE CAB FLOOR").
Carry out the following operations to clean the element:
1.
Remove the screws (1), remove the outer guard (2) and ex-
tract the filtering element (3).
2. Hit the element slightly on the palm of your hand to eliminate
the dust and blow compressed air on its surfaces, keeping
the jet at a distance of about 15 cm and making sure that the
pressure does not exceed 4÷5 bars.
3. Carefully clean the filter casing, taking care to prevent any
foreign body from entering the suction duct, and reassemble
the unit.
IMPORTANT
q
If the filtering element is excessively clogged or damaged,
change it with a new one.
