Using The Grinder
Failure to wear safety glasses while operating the grinder could cause serious personal eye injury.
The Model H3117 is best suited for high RPM, low torque applications. Most opera- tions performed with the grinder will per- form best at the higher RPM settings; how- ever, slower RPM settings are ideal when working with plastics that melt easily.
Always test the bit and RPM combination on a scrap piece of material similar to the workpiece. Trial and error is the best way to determine the ideal setup.
To use the grinder:
1.Grasp the grinder with a secure grip.
2.Turn the Power Switch to the ON “O” position.
3.Adjust the Speed Dial to change the RPM. “1” is the lowest RPM and “Max” is the highest RPM. The best speed for each job can vary.

High RPM Uses
Higher RPM settings are best for general carving, cutting, routing, and grinding. The grinder will perform more work at faster RPM settings.
Low RPM Uses
Lower RPM settings are best for grinding and cutting materials that have low melting points. Plastics in particular will often melt from the extreme heat generated by high speed bits.
Use low RPM settings when working with plastics or other materials with low melting points. Melted plastics can liquefy, be thrown into the air, and stick to the operator, causing serious personal injury.
Low RPM settings are also ideal for polish- ing and buffing with the felt accessories included.
