USE OF 5" RESIN DIAMOND PADS
Once the 5" resin diamond pad is positioned on the rubber or rigid backer pad on the right end of the
shaft, adjust the Loc Line nozzle tip to the center of the resin diamond pad as close as possible to the
center of the pad. This will allow the water stream/drip to flow over the pad while turning to cool and
flush gemstone grindings during use.
Always pump clean, clear water to the Loc Line manifold and discard dirty water and grindings from
the collection container periodically. Do not recirculate water as contaminants may scratch the gem-
stone material. The resin diamond pads should never be used dry or they will likely be prematurely
worn out or permanently damaged. A small amount of cooling water flow directed to the center of the
resin diamond pads is required to flush the gemstone grindings and keep the resin cool during use
of the GP6 (Pads) unit. Excess water flow directed to the pads is not necessary and will only make a
mess of your work area. The 5" resin diamond pads can be used with both flat and domed material,
the user should rock and rotate the domed gemstone material during polishing, but for flat polishing
the user needs to move the material flat face across the pad to fully polish the face uniformly. Gem-
stone material should be held firmly by the user’s finger tips while rotating and or moving the material
over the face of the 5" resin diamond pads. Do not hold the gemstone material too close to the bottom
edge of the resin pad or the material may jam the users finger against the reservoir base. In some
cases, the user may polish gemstones after perform grinding/sanding with the 80 and 170/200 mesh
brazed diamond wheels without need to use the resin diamond belts as the 5" resin diamond pads will
produce final polishing results as good as the resin diamond belts as the pads extend to 13,000 grit
size. Final polishing buffing can be performed with the Polytex pads and leather cowhide mounted to
the polishing foam disc.
