Inspect and Clean the Cooling Package
1. Prepare the machine for service. See “Maintenance
2. Open the engine hood.
NOTE:
Maintain a minimum distance of
12 in. (30 cm) from the cooling
fins during cleaning.
3. Check the front and rear of the radiator (1) and
hydraulic oil cooler (2) for dirt or debris. Use
compressed air or pressurized water in the opposite
direction of the airflow through the cooling package.
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.
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.
•
Engine coolant is toxic. Avoid inhaling or ingesting engine coolant.
•
Do not remove the radiator cap while the engine is hot. Engine coolant is under pressure
when hot and could spray out. Always wait for the engine to cool before removing the
radiator cap.
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.
•
Never direct compressed air, high-pressure water, or steam directly into the cooling fins.
Damaged cooling fins may lead to leaks and overheating. In dusty environments, inspect
the cooling fins daily regardless of the maintenance schedule.
