MAINTENANCE SERVICE PROCEDURE
4-31
CLEAN TRANSFER OIL COOLER FINS 4
WARNING
If compressed air, high-pressure water, or steam hits your body directly or dirt is sent flying by the com-
pressed air, high-pressure water, or steam, there is danger of personal injury. Always wear protective
glasses, dust mask, and other protective equipment.
Clean the oil cooler if mud or dirt is stuck to it.
1. Remove cover (1).
2. Use compressed air to clean the mud, dust, and leaves
from the oil cooler fins (2). Steam or water may be used
instead of compressed air.
3. After cleaning, install the cover (1).
NOTICE
If the steam jet nozzle is brought too close to the oil cooler
fins, it may damage the fins, so keep the nozzle a suitable
distance away from the fins when cleaning.
CHECK ELECTRICAL INTAKE AIR HEATER 4
Before the start of the cold season (once a year), contact your Komatsu distributor to have the electrical intake air
heater checked for dirt or disconnections.
