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.

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 1⁄8" 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

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

motor. Periodically remove and inspect the

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
The Model H3117 is an insulated and UL®
listed tool which should only be repaired by
a qualified technician. DO NOT attempt to
open the tool housing or perform any elec-
trical repair. Contact or Customer Service
