2. Place an oil drain pan below the filter being changed.

3. Remove the used filter either by hand or with a filter wrench/strap. When using a

filter wrench/strap make sure the tool is positioned within 2 inches of the top.

Tighten by hand until the gasket contacts the base, then rotate an additional 3/4 turn

Section 8 – Taking an Oil Sample

Frequency

We recommend that you:

 Take fluid samples when filters are changed

 Take oil samples at reduced intervals if results of the previous sample indicate a

potential issue.

Procedure

1. Insure that the sampling valve is closed (as shown in Figure 1).

2. Remove the cap from the sampling valve.

Note: To ensure an accurate sample reading, purge the sampling valve to flush out

impurities that may have settled in the valve opening.

3. Hold a clean sampling bottle under the sampling valve and open the valve until

the bottle is filled to the top line. DO NOT completely fill the sample bottle as it

may cause leaking during shipping.

4. Screw the cap tightly onto the sample bottle.

5. Screw the Safety Cap back onto the Sampling Valve.
