Use compressed air, high-pressure water, or steam to remove dust and other debris from the radiator fins. The maximum air pressure for cleaning purposes must be reduced to 205 kPa (30 psi). The maximum water pressure for cleaning purposes must be below 275 kPa (40 psi). However, the use of compressed air is preferred. Refer to Operation and Maintenance Manual, "General Hazard Information" for Safety information about using pressurized air and water.

Swing the hydraulic oil cooler and the air conditioner condenser back into the operating position.
The fuel cooler does not swing out. The wand must be placed behind the fuel cooler between the fuel cooler and radiator cores to clean out the fuel cooler.
