Oil Cooler Maintenance Instructions (Only tank unit type)
WARNING
Before starting maintenance work, stop the unit running and shut off the
source power supply.
Wear protective glasses and gloves for this work.
1)
The oil cooler fins are sharp, so take care.
2)
When using air blow, take care to avoid getting foreign matter in
your eyes.
CAUTION
Take care to ensure that no excessive forces are applied to the power cable or connector of the DC fan
during the work.
Note that oil will flow out from the piping and oil cooler during disassembly.
12.7.1
Removing the oil cooler
1.
Disconnect the connector for the DC fan wiring.
2.
Remove the hose clamps (2 locations), and pull off the two hoses fitted to the oil cooler.
At this time, fit e.g. a blind plug to the hoses before starting further work since oil may leak due to
reverse flow of oil from the tank.
3.
Remove two cross-recessed hexagonal bolt and washer assemblies (M6
20L) and remove
the oil cooler.
