plug pulled from the outlet. Wait for all
moving parts to come to a complete stop.
12. HEARING PROTECTION & HAZARDS.
Noise generated by blade and workpiece
vibration, material handling, and power
transmission can cause permanent hear-
ing loss over time and interfere with com-
munication and audible signals.
13. HOT SURFACES. Contact with hot sur-
faces from machine components, ejec-
tions of hot chips, swarf and workpiece
can cause burns.
1. BLADE CONDITION. Do not operate with
dull, cracked or badly worn blade. Inspect
blades for cracks and missing teeth before
each use.
2. HAND PLACEMENT. Never position fin-
gers or thumbs in line with the cut. Hands
could be crushed in vise or from falling
machine components.
3. ENTANGLEMENT HAZARDS. Do not
operate this bandsaw without blade guard
in place. Loose clothing, jewelry, long hair
and work gloves can be drawn into working
parts.
4. BLADE REPLACEMENT. When replacing
blades, make sure teeth face toward the
workpiece. Wear gloves to protect hands
and safety glasses to protect eyes.
5. WORKPIECE HANDLING. Always support
the workpiece with table, vise, or some
type of support fixture. Flag long pieces
to avoid a tripping hazard. Never hold the
workpiece with your hands during a cut.
6. LOSS OF STABILITY. Unsupported
workpieces may jeopardize machine sta-
bility and cause the machine to tip and fall
which could cause serious injury.
7. POWER INTERRUPTION. Unplug machine
after power interruption. Machines without
magnetic switches can start up after power
is restored.
No list of safety guidelines can be complete. Every shop environment is different. Like all
machines there is danger associated with the Model G9743. Accidents are frequently caused by
lack of familiarity or failure to pay attention. Use this machine with respect and caution to lessen
the possibility of operator injury. If normal safety precautions are overlooked or ignored, serious
personal injury may occur.
-10- G9743 7" x 12" Metal-Cutting Bandsaw
Serious personal injury could occur if you
connect the machine to the power source
before you have completed the set up pro-
cess. DO NOT connect the machine to the
power source until instructed to do so.
110/220V Operation
SECTION 2: CIRCUIT REQUIREMENTS
Amperage Draw
The Model G9743 features 110/220V motor that is
prewired for 110V and draws the following amps
under maximum load:
Motor Draw at 110V ...............................23 Amps
Motor Draw at 220V ........................... 11.5 Amps
Circuit Requirements
We recommend connecting this machine to a
dedicated circuit with a verified ground, using the
circuit breaker size given below. Never replace a
circuit breaker with one of higher amperage with-
out consulting a qualified electrician to ensure
compliance with wiring codes. If you are unsure
about the wiring codes in your area or you
plan to connect your machine to a shared cir-
cuit, you may create a fire hazard—consult a
qualified electrician to reduce this risk.
110V Circuit Breaker ............................. 25 Amps
220V Circuit Breaker ............................. 15 Amps
Figure 2. 6-15 plug and outlet.
Plug Type
The Model G9743 comes prewired with a NEMA
5-15 plug. If you wish to rewire the motor to 220V
you will need the following 220V plug (see Figure
2 for an example):
220V Plug & Receptacle .............................. 6-15
The Model G9743 can be rewired to operate on a
220V power source. The motor must be rewired
according to the wiring diagram on the motor
label. The wiring configuration can also be found
on the inside of the motor wire cover, as well as
on Page 39.
Wiring for 220V
G9743 7" x 12" Metal-Cutting Bandsaw -11-
In the event of an electrical short, grounding
reduces the risk of electric shock. The grounding
wire in the power cord must be properly connect-
ed to the grounding prong on the plug; likewise,
the outlet must be properly installed and ground-
ed. All electrical connections must be made in
accordance with local codes and ordinances.
Extension CordsGrounding
This machine must have a ground prong in
the plug to help ensure that it is grounded.
DO NOT remove ground prong from plug
to fit into a two-pronged outlet! If the plug
will not fit the outlet, have the proper outlet
installed by a qualified electrician.
Electrocution or fire could
result if this machine is
not grounded correctly or
if your electrical configu-
ration does not comply
with local and state codes.
Ensure compliance by
checking with a qualified
electrician!
We do not recommend the use of extension
cords. Instead, arrange the placement of your
equipment and the installed wiring to eliminate
the need for extension cords.
If you find it absolutely necessary to use an
extension cord at 110V with your machine:
• Use at least a 10 gauge cord for 110V and 14
gauge cord for 220V that does not exceed 50
feet in length!
• The extension cord must also contain a
ground wire and plug pin.
• A qualified electrician MUST size cords over
50 feet long to prevent motor damage.

Floor Load
The weight and footprint size for your machine
is located in the machine data sheet.
Most floors
are suitable for your machine. Some residential
floors may require additional reinforcement to
support both the machine and operator.
Working Clearances
Consider existing and anticipated needs, size of
material to be processed through each machine,
and space for auxiliary stands, work tables or
other machinery when establishing a location for
your new machine. See Figure 4 for the minimum
working clearances.
Unsupervised children and
visitors inside your shop
could cause serious per-
sonal injury to themselves.
Lock all entrances to the
shop when you are away and
DO NOT allow unsupervised
children or visitors in your
shop at any time!
The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during ship-
ment. Remove this protective coating with a sol-
vent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. To clean thoroughly,
some parts may need to be removed. For opti-
mum performance from your machine, make
sure you clean all moving parts or sliding
contact surfaces that are coated. Avoid chlo-
rine-based solvents, such as acetone or brake
parts cleaner, as they may damage painted sur-
faces should they come in contact. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
Site ConsiderationsClean Up
Gasoline and petroleum
products have low flash
points and could cause
an explosion or fire if
used to clean machinery.
DO NOT use gasoline or
petroleum products to
clean the machinery.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest-
ed. Lack of ventilation
while using these sol-
vents could cause seri-
ous personal health risks
or fire. Take precautions
from this hazard by only
using cleaning solvents
in a well ventilated area.

many variables involved with shipping, we recom-
mend that you at least verify the following adjust-
ments to ensure accurate cutting results.
Step-by-step instructions on verifying these adjust-
ments can be found in SECTION 7: SERVICE
ADJUSTMENTS.
Factory adjustments that should be verified:
1. Blade Tracking (Page 33).
2. Squaring the Blade (Page 34).
3. Blade Guide Bearings (Page 35).
