- Remove the bearing covers with a Phillips screwdriver (see pictures below)
- Make sure the posts the agate bearings free float on are clean
- Clean the agate bearings, especially the "V" notches
- Re-install the covers
- Clean the knife edges
- Level the bench surface using a bubble level at 90 degrees
- Turn HVAC/vent off and close the window/door to the room as any ambient air movement will affect scale reading/zero
- Place the powder pan on the pan support
- Set both large and micrometer poises to zero
- Lock the micrometer poise with the nylon bolt (for Ohaus/RCBS 10-10)
- Adjust the leveling foot so the pointer is at the zero line"
