6.4 Cleaning radiator, motor fan guard and pump
Radiator, motor fan guard and pump must be kept clean. This can be done using compressed air and a dry
cloth. Be careful not to damage the oil cooler (if applicable) by cleaning with compressed air or by exerting
excessive pressure with the cloth.
Do not use fluids or substances other than those indicated.
6.5 Cleaning the intake filter (optional) element
1. Remove the intake filter element from the housing.
2. Clean the intake filter element in one of the following ways:
Hand washing:
Soak and agitate element in a warm water and mild detergent solution. Allow adequate time for the
element to air dry (24 hours minimum). Do not install a damp element. This will cause higher initial
pressure loss and rapid dirt loading.
Compressed air cleaning:
Using approximately 7 bar(e) ( 100 psi(g)), direct air flow at inside of element towards pleats. Blow off
the outside of the element directing the air flow down to avoid embedding dirt in the media. Blow off
the inside again to remove any dirt that might be on the clean side of the element.
Vacuum cleaning:
Point the vacuum cleaner to the dirty side (outside of element) only, using a vacuum of approximately
100 mbar(a) (75 torr). A crevice tool is recommended.
Hand cleaning:
Hold element down with one hand and move other hand across the fins in a strumming motion. This
action will dislodge most of the dirt.
3. The element is ready to be reused.
