Portable Particle Analyzer Procedure
When using a portable particle analyzer for particle counting, be sure that you read and understand the Tool Operating Manual before operating the particle counter.

(17) S O S Valve
Attach the fabricated particle counter "low pressure in" suction tube to the S O S valve (17) on the filter cart.Note: The fabricated suction tube (14) can be made with the parts listed in Table 3 under the "Optional Tools" section. The fabricated tube is shown in Illustration 13.
Attach the other end of the fabricated suction tube (14) to the "low pressure in" port on the particle counter as called for in the Tool Operating Manual.Bottle Sample Procedure

(18) Bottle Group
If collecting a bottle sample, use the same S O S valve (17) and a 169-8373 Fluid Sampling Bottle (18). Refer to Illustration 14.
Record an oil sample reading from the S O S valve on the filter cart at the beginning of the procedure.
At the halfway point of filtering, stop the procedure and change the hydraulic filters on the machine. Changing the filters allows the filters to assist in the system cleaning. The new filters can remain in place until the next scheduled filter change. Changing the filters avoids opening the filter housing after the system has been cleaned. If the filter housing, is opened for any reason the housing becomes an inlet for contamination.Note: The filters on the machine are to be changed at the normal maintenance interval, or when the filters are not operating at optimal performance.
Operate the filter cart until the portable particle analyzer indicates that the oil has reached an acceptable ISO level of 18/15. The final ISO code should be recorded before the machine is returned to service.Note: Refer to"Oil Compartment Filtration Times for 204-7392 Filter Cart" locatedat the end of this document, when a portable particle analyzer is not available.
When the target ISO level or the time interval has been met, close the air supply valve and disconnect the air supply hose.
Remove the discharge hose assembly and the discharge adapter assembly from the hydraulic tank fill location. Install the dust cap on the nipple and on the quick coupler. Store the discharge adapter in a clean location.
Install a clean hydraulic tank filler cap.
Disconnect the filter cart suction hose (13) from the suction adapter (12). Install the dust cap on the nipple and the quick coupler. Refer to Illustration 9.
Place a drain pan under the hydraulic tank drain valve assembly. There may be some oil left in the hydraulic tank suction adapter assembly.
Remove the suction adapter from the hydraulic tank drain valve.
Reinstall a clean hydraulic tank drain plug into the hydraulic tank drain valve assembly.
Store the suction adapter in a clean location.
Check the hydraulic tank oil level before returning the machine to the field.Oil Compartment Filtration Times for 204-7392 Filter Cart
