(14) Fabricated suction tube
If collecting a bottle sample, use the same S O S Valve (11) and a 169-8373 Fluid Sampling Bottle (14). Refer to Illustration 12.
Record an oil sample reading from the S O S Valve (11) on the filter cart at the beginning of the filter cycle.
Cycle the hoist at least four times every 30 to 60 minutes during the filter cart operation. Operation of the hoist will cycle the clean tank oil into the hydraulic system. Cycling the hoist will also flush the more contaminated oil back into the tank. The oil filtration may be performed when then engine is running.
Stop the procedure after 30 minutes of filtering. Change the machine hydraulic filter. Changing the filter allows the filter to help in the cleaning of 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.

Operate the filter cart (15) until the Portable Particle Analyzer indicates that the oil has reached an ISO level of 18/15. Take a final oil sample and record the final ISO level before the machine is returned to the field.Note: Refer to "Oil Compartment Filtration Times for 188-3242 Filter Cart", at 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 (10) and disconnect the air supply hose (9). Refer to Illustration 9.
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.

(16) Probe
(17) S O S valve (on the filler cap adapter)
To relieve possible tank pressure, use a probe (16) from the 169-8373 Fluid Sampling Bottle. Use the probe used in Step 17 and depress the S O S valve (17) on the filler cap adapter. Refer to Illustration 14.
Disconnect the filter cart suction line (6) from the filler cap adapter suction port (5). Refer to Illustration 8.
Disconnect the filter cart return line (7) from the filler cap adapter return port (8). Refer to Illustration 7.
Remove the filler cap adapter (2). Refer to Illustration 5.
Install protective caps to the filler cap adapter, the filter cart suction line, and the filter cart return line to control contamination.
Install the strainer and the lock-ring into the hydraulic filler neck.
Install the hydraulic oil fill cap (1). Refer to Illustration 3.
Check the oil level by viewing the hydraulic tank sight gauge.
Inspect the hydraulic system for leaks. Most hydraulic contamination is brought into the system from an external source. Repairs must be completed before the machine is returned to service to provide a long-term benefit.Oil Compartment Filtration Times for 188-3242 Filter Cart
If an on-line, portable particle counter is not available to diagnose and track when the contaminant level has lowered to an acceptable point, refer to the following equation. This equation
