Clean And Inspect Radiator Fins, Oil Cooler Fins And Condenser Fins (Only For Machines Equipped With Air Conditioner) - Komatsu PC128UU-2 Operation & Maintenance Manual

MAINTENANCE PROCEDURE
CLEAN AND INSPECT RADIATOR FINS, OIL COOLER FINS AND CONDENSER
FINS (ONLY FOR MACHINES EQUIPPED WITH AIR CONDITIONER)
If compressed air, high-pressure water, or steamhit your body directly, or they cause dirt or dust to be
blown up, there is a hazard of serious injury. Always use safety glasses, dust mask, or other protective
equipment.
NOTICE
When using compressed air, if the nozzle is brought too near the fins, the fins may be damaged. Carry out
the cleaning from a reasonable distance to prevent damage to the fins.
Do not direct the jet directly at the core. If the fins are damaged, it will cause leakage of water and over-
heating. On dusty jobsites, carry out this inspection every day, regardless of the maintenance interval.
1. Open the cover at the rear of the cab and the battery
room door at the left side of the machine.
2. Use compressed air to clean the mud, dust, and leaves
from the radiator fins, oil cooler fins, and condenser fins.
Steam or water may be used instead of compressed air.
3. Check the rubber hose. Replace with a new one if the
hose is found to have cracks or to be hardened by age-
ing. Further, check hose clamps for looseness.
