13.5.2 Disassembling the oil cooler
Remove four cross-recessed pan-head screw and washer assemblies (M5 x 10L), and separate the core
and shroud. Remove four cross-recessed hexagonal bolt and flat washer assemblies (M4 x 50L), and
separate the shroud, DC fan and finger guard.
13.5.3 Cleaning the core
Steam blow or air blow the core to blow dirt and contamination that has been deposited on or is adhering
to the fins, making the fin section clean. When doing this, take care to ensure that dirt or adhering
material is not blown into the interior of the core.
13.5.4 Cleaning the DC fan
Using e.g. a rag, clean not just the fan blades and casing, but also the clearance between the fan blades
and casing.
CAUTION
 Never steam blow or air blow because foreign material will get inside the motor.
13.5.5 Reassembly
After completing the cleaning, reassemble to the original state. After completion of reassembly, check
that the unit runs normally by following the test run instructions in “Chapter 10 TRIAL RUNNING”. 
