CHECK & VERIFY OPERATION:

46. To verify the fan operation, the temp sensor must be by-passed. By-pass the temp sensor by disconnecting it from the green wires of the control box. Reconnect the two green wires (control box) into each other to form a loop.

Reconnect the battery. Turn on the ignition key without starting the engine.

The roof cooler fan should start after a 30 second delay if the temp sensor is by-passed.

Turn ignition switch off. Reconnect the temp sensor.

47. Re-check all the hoses and wires from the roof cooler so they are not pinched or kinked along their path.

48. Recheck all the hydraulic connections. Start engine and function loader arms slowly. Unlock safety lever & lower loader arms to ground. Carefully observe for any hydraulic leaks. Caution: Do not use exposed skin to test for hydraulic leaks. High pressure oil can be injected into the skin. If oil is injected into the skin, seek immediate medical attention as serious side affects and death can occur.

CLEANING THE COOLER:

49. The cooler should be cleaned on a regular basis. The cooling efficiency of any cooler is greatly reduced, if the screens are blocked or the cooler core fins are plugged with debris.

The bottom screen pulls out for easy cleaning.

The fan has on auto-reversing cycle to help keep the lower screen clean during operation.

50. The top unbolts for access to the fan, fan controller, temperature sensor, check valve and cooler core.

51. The fan and shroud top pivot up for access to the cooler core fins. When cleaning the cooler core, be careful not to bend over the small cooler fins as this will severely affect the cooling capacity. Low pressure water or high pressure air can be used with caution. High pressure water is not recommended.

OPERATION: 52. In typical operation, the temp sensor will turn the fan on when the hydraulic oil temperature reaches 140ºF. Once the fan is operating, it will run for 30 seconds in the reverse direction blowing air down and cleaning off the lower screen. After 30 seconds the fan will stop, pause and change direction.

- 14 -

Next the fan will run for 10 minutes in the forward direction blowing air up and out through the top. The fan will repeat this cycle every 10 minutes. The temp sensor will turn the fan off if the hydraulic oil falls below 130-125ºF.
