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.
