Typical S O S port connection
(11) S O S valve
(12) 210-5530 Quick Connect Coupler
(13) 188-0639 Hose As
Attach the 210-5530 Quick Connect Coupler (12) and fabricated suction tube (13) to the S O S valve (11) on the machine.Note: The S O S valve-specific location can be found in the Operation and Maintenance Manual for the machine.
Attach the other end of the fabricated suction tube (13) to the portable particle counter as called for in the Tool Operating Manual.Note: A 188-0639 Hose As will need to be purchased prior to assembly.

(11) S O S valve
(14) 169-8373 Fluid Sampling Bottle
If collecting a bottle sample, use the same S O S valve (11) and a 169-8373 Fluid Sampling Bottle (14).
Record an oil sample reading from the S O S valve (11) on the machine at the beginning and end of the filter cycle.Finishing the Filtration Process
At the halfway point of the filtration procedure, stop the procedure and change the hydraulic oil filter. Changing the filter allows the filter to help with cleaning the system. The new filter can remain in place until the next scheduled filter change. Changing the filter now avoids opening the filter housing after the system has been cleaned. An open filter housing is an inlet for contamination.
Cycle the oil until the portable particle analyzer indicates that the oil has reached an acceptable contaminant level of a minimum ISO 18/15. Take a final oil sample and record the final ISO level before the machine is returned to the field.Note: Refer to Table 8 at the end of this document when a portable particle analyzer is not available.
When the target ISO level or time interval has been met, turn off the machine and relieve the system pressure.
Disconnect the filter couplers from the machine couplers.
Check the hydraulic tank oil level and return the machine to service.Oil Compartment Filtration Times

ISO (International Organization of Standardization) is a worldwide federation of national standards bodies. The ISO 4406:1999 specifies the code to be used in defining the quantity of solid particles in the fluid used in any given hydraulic fluid power system. An automatic particle counter derives the equivalent size of a particle from the cross sectional area of the particle. Particle counts are affected by various factors. These factors include procurement of the sample, the sample container, particle counting accuracy, where used and the particle counter cleanliness. Proper care should be taken during sample procurement to ensure that the sample obtained is representative of the fluid circulation in the system.The code for contamination levels using automatic particle counters is composed of three scale
