Slide the air conditioner condenser screen out toward the right side of the machine to remove. Loosen wing nut and slide the air conditioner condenser toward the left side of the machine until it hits the stop. Clean air conditioner condenser, screen, and fuel cooler with compressed air. If a more thorough cleaning is required perform the following. Loosen wing nuts on each side of the charge air cooler and pivot forward.

Tighten wing nuts to retain position. Pull handle of the hydraulic oil cooler toward to left side of the machine until it hits the stop. Clean charge air cooler, hydraulic oil cooler, and radiator with compressed air. Straighten any bent fins. Return coolers, condenser, and screen back to original position and tighten wing nuts to secure in place. Verify that hydraulic oil cooler hoses are under the protective shield. Verify that all lines are not pinched or kinked when coolers are repositioned. Lower hood.
