POWER SUPPLY
Full-Load Current Rating at 120V 16.92 Amps
Availability
Before installing the machine, consider the avail-
ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
Electrocution, fire, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
Full-Load Current Rating
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup-
ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
120V Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage .................... 110V, 115V, 120V
Cycle ..........................................................60 Hz
Phase ........................................... Single-Phase
Power Supply Circuit ......................... 20 Amps
Plug/Receptacle ............................. NEMA 5-15
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.

Model G0458ZX (Mfd. Since 11/23) -5-
Minimum Gauge Size ...........................12 AWG
Maximum Length (Shorter is Better).......50 ft.
Grounding & Plug Requirements
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon-
nect it from power, and immediately replace it with
a new one.
Extension Cords
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:

5-15 PLUG

SHOCK HAZARD!
Two-prong outlets do not meet the
grounding requirements for this machine.
Do not modify or use an adapter on the plug
provided—if it will not fit the outlet, have a
qualified electrician install the proper outlet
with a verified ground.

This machine was carefully packaged for safe
transport. When unpacking, separate all enclosed
items from packaging materials and inspect them
for shipping damage.
If items are damaged
,
please
call us immediately at [phone].
IMPORTANT: Save all packaging materials until
you are completely satisfied with the machine and
have resolved any issues between Grizzly or the
shipping agent. You MUST have the original pack-
aging to file a freight claim. It is also extremely
helpful if you need to return your machine later.
Unpacking
This machine presents
serious injury hazards
to untrained users. Read
through this entire manu-
al to become familiar with
the controls and opera-
tions before starting the
machine!
Wear safety glasses during
the entire setup process!
HEAVY LIFT!
Straining or crushing injury
may occur from improperly
lifting machine or some of
its parts. To reduce this risk,
get help from other people
and use a forklift (or other
lifting equipment) rated for
weight of this machine.

nut or a washer), we will gladly replace them; or
for the sake of expediency, replacements can be
obtained at your local hardware store.
NOTICE
If you cannot find an item on this list, care-
fully check around/inside the machine and

Weight Load
Refer to the
Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest work-
piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main-
tenance and service described in this manual.
See below for required space allocation.
Physical Environment
The physical environment where the machine is
operated is important for safe operation and lon-
gevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemi-
cals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20%–95% (non-condensing); or
the environment is subject to vibration, shocks,
or bumps.
Electrical Installation
Place this machine near an existing power source.
Make sure all power cords are protected from
traffic, material handling, moisture, chemicals, or
other hazards. Make sure to leave enough space
around machine to disconnect power supply or
apply a lockout/tagout device, if required.
Lighting
Lighting around the machine must be adequate
enough that operations can be performed safely.
Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.

Note: We recommend assembling the stand
upside down. To make it easier, have an assistant
hold the pieces while you assemble the stand.
DO NOT final-tighten stand bolts until
stand components have been assembled.
The machine must be fully assembled before it
can be operated. Before beginning the assembly
process, refer to
Needed for Setup
and gather
all
listed items.
To ensure the assembly process
goes smoothly, first clean any
parts that are
cov-
ered or coated in heavy-duty rust preventative (if
applicable).
