Additional Safety Instructions For Surface 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 personal injury,
damage to equipment or poor work results.
Like all power tools, there is danger associated with the Model G5963 Surface Grinder. Use
the tool with respect and caution to lessen the
possibility of mechanical damage or operator
injury. If normal safety precautions are overlooked or ignored, serious personal injury may
occur.
1. Ensure that the machine sits firmly on the
floor before use. Any “wobbles” must be
corrected by shimming or blocking before
operation.
2. This machine is not designed to process
any other material except metals.
3. Never position fingers or hands directly
between the grinding wheel and the table.
4. Do not operate surface grinder with
cracked or damaged grinding wheels.
5. Always use extreme care in handling grinding wheels during installation. Always “ring
check” the wheel to determine possible
damage.
6. Ensure that the surface grinder is properly
adjusted before using.
7. Never load or unload the workpiece while
the grinding wheel is rotating or the table is
moving.
8. If using coolants for grinding, always read
and understand the user information listed
on the coolant container. Some coolants
used for machining may be hazardous to
your health if not used and stored properly.
9. This manual is intended to familiarize you
with this grinding machine. It is not, nor
was it ever intended to be, a comprehensive training manual.
Operation of this equipment has the potential
to propel debris into the air which can cause
eye injury. Always wear safety glasses or goggles when operating equipment. Everyday
glasses or reading glasses only have impact
resistant lenses, they are not safety glasses.
Be certain the safety glasses you wear meet
the appropriate standards of the American
National Standards Institute (ANSI).

SECTION 2: CIRCUIT REQUIREMENTS
110V Operation
The motor supplied with the G5963 can be operated at either 110V or 220V. The motor comes
prewired for 110V. If you wish to operate at 220V,
refer to the section at right.
Under normal use, the motor draws approximately 7.4 amps @ 110V. We recommend a 15 amp
circuit breaker for 110V operation. This should be
satisfactory for normal use, while providing
enough protection against motor damage caused
by power surges.
Grizzly recommends that the circuit you use
should be dedicated, (i.e., the G5963 should provide the only draw from that circuit). If frequent
circuit failures occur when using the Surface
Grinder, contact our Service Department or your
local electrical contractor.
220V Operation
The G5963 Surface Grinder motor can be rewired
to operate at 220V. Refer to the wiring diagram
supplied with this manual. If converting to operate
at 220V, the 110V plug must be replaced with a
220V plug. Plugs and receptacles can be purchased at your local hardware store or home center. The type of plug you choose will depend upon
the type of 220V outlet used in your installation.
See Figure 2 for a typical plug and outlet. This
plug must be rated for at least 15 amp draw.
It is not necessary to change the switch supplied
with the G5963 for 220V operation.
Under normal 220V use, the motor draws approximately 3.7 amps. We recommend a 10 amp circuit breaker or a 10 amp slow-blow fuse.
Figure 1. Typical 110V plug and outlet.
Figure 2. Typical 220V plug and outlet.
-6- G5963 Surface Grinder
We do not recommend the use of extension
cords on 220V equipment. It is much better to
arrange the placement of your equipment and the
installed wiring to eliminate the need for extension cords. Should it be necessary to use an
extension when operating at 110V, make sure the
cord is rated Hard Service (grade S) or better.
Refer to the chart in Section 1: Safety Instructions
to determine the minimum gauge for the extension cord. The extension cord must also contain
a ground wire and plug pin. Always repair or
replace extension cords when they become worn
or damaged.
Extension Cords
This equipment must be grounded. Please
ensure that this machine is continuously
grounded from the motor to the machine frame
and then to a known ground. Verify that any
existing electrical outlet and circuit you intend
to plug into is actually grounded. If it is not, it
will be necessary to run a separate 12 A.W.G.
copper grounding wire from the outlet to a
known ground. Under no circumstances should
the grounding pin from any three-pronged plug
be removed. Serious personal injury may
occur.
We have covered some basic electrical
requirements for the safe operation of your
Surface Grinder. These requirements are not
necessarily comprehensive. You must be sure
that your particular electrical configuration
complies with local and state codes. Ensure
compliance by checking with your local municipality or a licensed electrician.
Grounding
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric current. This tool is equipped with a power cord having an equipment-grounding conductor. See
Figure 1 and 2. The outlet must be properly
installed and grounded in accordance with all
local codes and ordinances.
Check Motor Rotation
After the machine is assembled and properly
connected to electrical power, test the motor rotation. Cycle the machine on and observe the rotation of the grinding wheel. Make sure it rotates in
the direction indicated by the arrow on the wheel
guard. If it does not, the wiring may not be properly connected at the motor. Disconnect from the
power source, and check that the motor wiring
agrees with the wiring diagram provided in this
manual. Make necessary adjustments, close the
motor cover, reconnect to power, and test again.
