Inspect and Clean the Radiator and Oil Cooler Fins
1. Prepare the machine for service. See “Maintenance Safety” on page 2-8.
2. Open the left rear access door. See “Left Rear Access Door” on page 3-6.
WARNING!
Do not allow compressed air, pressurized water, or steam to come into contact with skin.
Always wear goggles, gloves, and other personal protective equipment (PPE). Failure to
follow these warnings could result in death or serious injury.
NOTICE!
•
Compressed air, high-pressure water, or steam can damage the cooling fins if the nozzle is
too close to the fins. To prevent cooling fin damage, keep the nozzle at a safe distance
while cleaning. Damaged cooling fins may lead to leaks and overheating.
•
In dusty environments, inspect the cooling fins daily regardless of the maintenance
schedule.
Failure to follow this notice could result in damage to the machine or cause it to operate
improperly.
NOTE:
Maintain a minimum distance of 12 in.
(30 cm) from the cooling fins during cleaning.
3. Use compressed air or pressurized water in the
opposite direction of the airflow through the cooling
package to clean the turbocharger intercooler (1),
engine coolant radiator (2), and hydraulic oil cooler
(3).
4. Check the fins for deformation, corrosion, and cracks
after cleaning. Repair the component immediately if
damaged cooling fins are found.
5. Check the hose clamps. Tighten as necessary.
6. Inspect the area below the coolers and remove any
debris that has accumulated during operations.
7. Close the left rear access door.
