[9] CHECKING/CLEANING RADIATOR AND OIL COOLER FINS
The dusts fly in all directions when the compressed air is used. Always wear goggles and mask.
CAUTION
• To prevent damage on the fins during the use of the compressed air, keep the pressure of the
compressed air to 0.20 -0.29 MPa (2 – 3 kg/cm
2
) and apply it away from the fins.
Damage on the fins will cause water leakage or overheating.
• At the dusty site, check the fins every day and clean as needed.
1. Stop the machine at leveled location.
2. See “Operation 2.14 Outrigger Setting Operation” to rotate the
rotary of the “outrigger (1)” and “outrigger (4)” outward.
3. Remove the six mounting bolts (2) and remove the radiator
cover (1).
4. Apply the compressed air (0.20 -0.29 MPa (2 – 3 kg/cm
2
)) to the
oil cooler (3) and radiator (4) to remove the mud and dusts
clogged in the fins.
5. Replace the radiator cover (1) to the original position and
securely tighten the six mounting bolts (2) after cleaning.
6. See “Operation 2.24 Outrigger Stowing Operation” and rotate
the rotary of the “outrigger (1)” and “outrigger (4)” inward and
stow.
