CAUTION: Wear goggles or safety glasses when using
compressed air [less than 0.2 MPa (2 kgf/cm
IMPORTANT: If compressed air with the pressure of more
than 0.2 MPa (2 kgf/cm
delivery pressure is used for cleaning, damage to the
radiator/oil cooler fins may result.
Keep the nozzle away from the core surface more than
500 mm.
Remove left and right access covers (1) and (2) to clean

with compressed air pressure (lower than 0.2 MPa (2 kgf/
cm ) (30 psi)) or tap water. It will prevent a reduction in
