INTRODUCTION
Machine Description
Manual Accuracy
We are proud to offer this manual with your new
machine! We've made every effort to be exact
with the instructions, specifications, drawings, and
photographs of the machine we used when writ-
ing this manual. However, sometimes errors do
happen and we apologize for them.
Also, owing to our policy of continuous improve-
ment, your machine may not exactly match the
manual. If you find this to be the case, and the dif-
ference between the manual and machine leaves
you in doubt, check our website for the latest
manual update or call technical support for help.
Before calling, find the manufacture date of your
machine by looking at the date stamped into the
machine ID label (see below). This will help us
determine if the manual version you received
matches the manufacture date of your machine.
For your convenience, we post all available man-
uals and manual updates for free on our website
at www.grizzly.com. Any updates to your model
of machine will be reflected in these documents
as soon as they are complete.

Safety Instructions for Machinery
4. ALWAYS USE HEARING PROTECTION
WHEN OPERATING MACHINERY.
Machinery noise can cause permanent
hearing loss.
5. WEAR PROPER APPAREL. DO NOT
wear loose clothing, gloves, neckties, rings,
or jewelry that can catch in moving parts.
Wear protective hair covering to contain
long hair and wear non-slip footwear.
6. NEVER OPERATE MACHINERY WHEN
TIRED OR UNDER THE INFLUENCE OF
DRUGS OR ALCOHOL. Be mentally alert
at all times when running machinery.
1. READ ENTIRE MANUAL BEFORE
STARTING. Operating machine before
reading the manual greatly increases the
risk of injury.
2. ALWAYS USE ANSI APPROVED
SAFETY GLASSES WHEN OPERATING
MACHINERY. Everyday eyeglasses only
have impact resistant lenses —they are
NOT safety glasses.
3. ALWAYS WEAR A NIOSH APPROVED
RESPIRATOR WHEN OPERATING
MACHINERY THAT PRODUCES DUST.
Most types of dust (wood, metal, etc.) can
cause severe respiratory illnesses.
For Your Own Safety, Read Instruction
Manual Before Operating this Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions. This
manual uses a series of symbols and signal words intended to convey the level of importance
of the safety messages. The progression of symbols is described below. Remember that safety
messages by themselves do not eliminate danger and are not a substitute for proper accident
prevention measures.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
This symbol is used to alert the user to useful information about
proper operation of the machine.

7. ONLY ALLOW TRAINED AND PROP-
ERLY SUPERVISED PERSONNEL TO
OPERATE MACHINERY. Make sure
operation instructions are safe and clearly
understood.
8. KEEP CHILDREN/VISITORS AWAY.
Keep all children and visitors away from
machinery. When machine is not in use,
disconnect it from power, lock it out, or
disable the switch to make it difficult for
unauthorized people to start the machine.
9. UNATTENDED OPERATION. Leaving
machine unattended while its running
greatly increases the risk of an accident or
property damage. Turn machine Off and
allow all moving parts to come to a com-
plete stop before walking away.
10. DO NOT USE IN DANGEROUS
ENVIRONMENTS. DO NOT use machin-
ery in damp, wet locations, or where any
flammable or noxious fumes may exist.
11. KEEP WORK AREA CLEAN AND WELL
LIGHTED. Clutter and dark shadows may
cause accidents.
12. USE A GROUNDED POWER SUPPLY
RATED FOR THE MACHINE AMPERAGE.
Grounded cords minimize shock hazards.
Operating machine on an incorrect size of
circuit increases risk of fire.
13.
ALWAYS DISCONNECT FROM POWER
SOURCE BEFORE SERVICING
MACHINERY. Make sure switch is in
OFF
position before reconnecting.
14. MAINTAIN MACHINERY WITH CARE.
Keep blades sharp and clean for best and
safest performance. Follow instructions for
lubricating and changing accessories.
15. MAKE SURE GUARDS ARE IN PLACE
AND WORK CORRECTLY BEFORE
USING MACHINERY.
Safety Instructions for Machinery
16. REMOVE CHUCK KEYS OR ADJUSTING
TOOLS. Make a habit of never leaving
chuck keys or other adjustment tools in/on
the machine—especially near spindles!
17. DAMAGED MACHINERY. Check for bind-
ing or misaligned parts, broken parts,
loose bolts, other conditions that may
impair machine operation. Always repair or
replace damaged parts before operation.
18. DO NOT FORCE MACHINERY. Work at
the speed for which the machine or acces-
sory was designed.
19. SECURE WORKPIECE. Use clamps or
a vise to hold the workpiece when practi-
cal. A secured workpiece protects your
hands and frees both hands to operate the
machine.
20. DO NOT OVERREACH. Maintain stability
and balance at all times when operating
machine.
21. MANY MACHINES CAN EJECT
WORKPIECES TOWARD OPERATOR.
Know and avoid conditions that cause the
workpiece to "kickback."
22. STABLE MACHINE. Machines that move
during operations greatly increase the
risk of injury and loss of control. Verify
machines are stable/secure and mobile
bases (if used) are locked before starting.
23. CERTAIN DUST MAY BE HAzARDOUS
to the respiratory systems of people and
animals, especially fine dust. Be aware of
the type of dust you are exposed to and
always wear a respirator designed to filter
that type of dust.
24. EXPERIENCING DIFFICULTIES. If at
any time you are experiencing difficulties
performing the intended operation, stop
using the machine! Contact our Technical
Support Department at [phone].

Additional Safety Instructions for Tool Post
Grinders
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre-
cautions are overlooked or ignored, serious
personal injury may occur.

Note: The tool post mounting hole of the
grinder will accept tool post studs up to 1" in
diameter. However, if the diameter or height
of your tool post stud allows for side-to-side
or up-and-down movement of the grinder
when the nut is fully tightened, you will need
to fabricate a custom bushing for the tool
post.
Unexpected movement of the grinder on
the tool post stud could cause the grinding
wheel to break apart and become an injury
hazard. Always make sure the grinder is
firmly secured to the tool post stud so that
there is no side-to-side or up-and-down
movement.
