Safety Instructions For Power Tools  
14. MAINTAIN TOOLS WITH CARE.  
Keep tools sharp and clean for  
best and safest performance.  
Follow instructions for lubricating  
and changing accessories.  
9. USE PROPER EXTENSION CORD  
for the tool. Make sure your exten-  
sion cord is in good condition.  
Conductor size should be in accor-  
dance with the chart below. The  
amperage rating should be listed on  
the motor or tool nameplate. An  
undersized cord will cause a drop in  
line voltage resulting in loss of power  
and overheating. Your extension  
cord must also contain a ground wire  
and plug pin. Always repair or  
replace extension cords if they  
become damaged.  
15. DISCONNECT TOOLS before ser-  
vicing and changing accessories,  
such as blades, bits, cutters, and  
the like.  
16. REDUCE THE RISK OF UNIN-  
TENTIONAL STARTING. Make  
sure switch is in off position before  
plugging in.  
17. USE RECOMMENDED ACCES-  
SORIES. Consult the owner’s  
manual for recommended acces-  
sories. The use of improper acces-  
sories may cause risk of injury.

18. CHECK DAMAGED PARTS.  
Before further use of the tool, a  
guard or other part that is dam-  
aged should be carefully checked  
to determine that it will operate  
properly and perform its intended  
function. Check for alignment of  
moving parts, binding of moving  
parts, breakage of parts, mount-  
ing, and any other conditions that  
may affect its operation. A guard or  
other part that is damaged should  
be properly repaired or replaced.

OPERATION  
3. While applying pressure to the Collet  
About Your New Grinder  
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.  
The Grizzly Model H3117 is a variable  
speed, rotary-style tool capable of speeds  
from 0-30,000 RPM. It is capable of a wide  
range of grinding, cutting, polishing,  
drilling, engraving, and cut-off operations.  
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.  
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.  
5. Insert the end of a bit into the Collet. At  
1
least  
2" of the bit shaft should be  
mounted into the end of the Collet.  
Installing Bits  
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.  
The Model H3117 can use most bits and  
cutters that have a 18" diameter shaft. See  
the Grizzly catalog or website for a com-  
plete listing of available bits and acces-  
sories.  
Before Start Up  
1. Be sure the bit and the Collet Nut are  
DO NOT use bits or cutters with a

Using The 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.  
Failure to wear safety glasses while  
operating the grinder could cause  
serious personal eye injury.  
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.  
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.  
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.  
To use the grinder:  
1. Grasp the grinder with a secure grip.  
Low RPM settings are also ideal for polish-  
ing and buffing with the felt accessories  
included.  
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.

source before performing any mainte-  
nance!  
Carbon Brushes  
The Model H3117 has a brush-type electric  
motor. Periodically remove and inspect the  
2 carbon brushes under the Brush Covers.  
New brushes have a grey-copper color. If  
the brushes are pitted, cracked, or are

Cleaning The Grinder  
While wearing safety glasses, periodically  
clean the grinder with compressed air. DO  
NOT use flammable products to clean the  
grinder.  
Gasoline or petroleum products used  
to clean the tool could explode caus-  
ing serious personal injury. DO NOT  
use gasoline or petroleum products  
to clean the tool.  
Repairs

listed tool which should only be repaired by  
a qualified technician. DO NOT attempt to
