OPERATION
About Your New Grinder
The Grizzly Model H3117 is a variable speed,
Please take the time to become familiar with this instruction manual. The informa- tion contained will allow you to get the maximum enjoyment and use from your new tool.
Installing Bits
The Model H3117 can use most bits and cutters that have a 1???8" diameter shaft. See the Grizzly catalog or website for a com- plete listing of available bits and acces- sories.
DO NOT use bits or cutters with a cutting surface larger than 1" in diameter. The bit could break apart under the stresses of high speed use causing serious personal injury.
To install a bit:
1.Unplug the tool from the power source!
2.Depress the Collet Lock. The Collet Lock is a small black button near the ip of the Grinder. Initially the Collet Lock may not depress when pushed; how- ever, continue to apply and hold pres- sure on the Collet Lock.
3.While applying pressure to the Collet Lock, use your other hand to rotate the Collet Nut and loosen it. At some point through the rotation the Collet Lock will engage, preventing further rotation of the Collet Nut.
4.With the Collet Lock engaged, the Collet Nut should easily loosen and unthread by hand. DO NOT complete- ly remove the Collet Nut from the shaft.
5.Insert the end of a bit into the Collet. At least 1???2" of the bit shaft should be mounted into the end of the Collet.
6.While depressing the Collet Lock, rotate the Collet Nut to secure the bit.
Only hand tighten the bit. Excessive tightening with the Collet Wrench is not necessary.
Before Start Up
1.Be sure the bit and the Collet Nut are secure on the grinder shaft.
2.Wear safety glasses and a dust mask when operating the grinder.
3.Turn the Power Switch to the OFF
4.Plug the grinder into the power source.

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.
H3117 Mini Grinder
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.
MAINTENANCE
Unplug the grinder from the power source before performing any mainte- nance!
