setting the zrs on the PE3 and pe4

Guide Number: SG0272 | Printer Friendly Version | View Safety Disclaimer

The ZRS should be adjusted ONLY after the rise & fall ruler is properly zeroed. If the ruler has been previously checked and is OK then you can skip to “Checking the ZRS” at step 10. Required tools: metal ruler 12″, Flat Blade Screw Driver, Flat metal diamond tool (must be FLAT)

Checking and Zeroing the Rise & Fall Ruler

With the Miter at 0°, Adjust the rise and fall so the pointer is pointing at “0”

checking the pointer

Place the Flat Edge Medium Diamond on the spindle and select “Spindle In”

Adjusting the hard stop

Adjust the hard stop so that the tool is flush with the top of the table

Is the tool still flush with Table Top

Move the Miter to 180°. The tool should still be flush with the table top. If it is you are done, the ruler is in the right place. If it is not continue to step 5

Fine Adjustments

Adjust the Rise & Fall until the tool is half the distance toward being flush. Example: If the tool is 1/2” below the table surface at 180°, adjust the Rise & Fall up so that the tool is only 1/4” below the table surface. The same is true if the tool is above the table except that you have to move the Rise & Fall downward

Move the Miter to 0°

Adjust the hard stop until the tool is again flush with the table top surface.

Adjust the hard stop until the tool is again flush with the table top surface.

Move the Miter to 180°

Is the Tool Flush?

If the tool is flush with the table top surface the Rise & Fall pointer should be adjusted with a
screwdriver so that the point is pointing at zero. If the tool is not flush repeat steps 5 – 9 until the tool is flush
