accident prevention measures.
NOTICE
G1073/G1073Z 16'' Bandsaw -3-
9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condition. Conductor size should be in accordance 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.
Minimum Gauge for Extension Cords
10. WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Non-slip footwear
is recommended. Wear protective hair covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also
use face or dust mask if cutting operation is
dusty. Everyday eyeglasses only have impact
resistant lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold
work when practical. It is safer than using your
hand and frees both hands to operate tool.
13. DO NOT OVERREACH. Keep proper foot-
ing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for lubricating and changing accessories.
Safety Instructions For Power Tools
15. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recommended accessories. The use of improper
accessories may cause risk of injury.
16. REDUCE THE RISK OF UNINTENTIONAL STARTING. On machines with mag-
netic contact starting switches there is a
risk of starting if the machine is bumped or
jarred. Always disconnect from power
source before adjusting or servicing. Make
sure switch is in OFF position before reconnecting.
17. MANY WOODWORKING TOOLS CAN
“KICKBACK” THE WORKPIECE toward
the operator if not handled properly. Know
what conditions can create “kickback” and
know how to avoid them. Read the manual
accompanying the machine thoroughly.
18. CHECK DAMAGED PARTS. Before fur-
ther use of the tool, a guard or other part
that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended function.
Check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that
may affect its operation. A guard or other
part that is damaged should be properly
repaired or replaced.
19. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Do not
leave tool until it comes to a complete stop.
20. NEVER OPERATE A MACHINE WHEN
TIRED, OR UNDER THE INFLUENCE OF
DRUGS OR ALCOHOL. Full mental alert-
ness is required at all times when running
a machine.
21. NEVER ALLOW UNSUPERVISED OR
UNTRAINED PERSONNEL TO OPERATE THE MACHINE. Make sure any
instructions you give in regards to the
operation of the machine are approved,
correct, safe, and clearly understood.

Additional Safety Instructions For Bandsaws
7. ALWAYS FEED STOCK EVENLY AND
SMOOTHLY. Do not force or twist blade
while cutting, especially when sawing
small radii.
8. THIS MACHINE IS NOT DESIGNED TO
CUT METAL or other material except
wood.
9. BLADE SHOULD BE RUNNING AT FULL
SPEED before beginning a cut.
10. DO NOT MANUALLY STOP OR SLOW
BLADE after turning the saw off. Allow it to
come to a complete stop before you leave
it unattended.
11. ALL INSPECTIONS, ADJUSTMENTS,
AND MAINTENANCE ARE TO BE DONE
WITH THE POWER OFF and the plug
pulled from the outlet. Wait for all moving
parts to come to a complete stop.
12. HABITS – GOOD AND BAD – ARE HARD
TO BREAK. Develop good habits in your
shop and safety will become secondnature to you.
13. IF AT ANY TIME YOU ARE EXPERIENCING DIFFICULTIES PERFORMING THE
INTENDED OPERATION, STOP USING
THE BANDSAW! Then contact our service
department or ask a qualified expert how
the operation should be performed.
1. DO NOT OPERATE WITH DULL OR
BADLY WORN BLADES. Dull blades
require more effort to use and are difficult
to control. Inspect blades before each use.
2. NEVER POSITION FINGERS OR
THUMBS IN LINE WITH THE CUT.
Serious personal injury could occur.
3. DO NOT OPERATE THIS BANDSAW
WITHOUT WHEEL, PULLEY, AND
BLADE GUARDS IN PLACE.
4. WHEN REPLACING BLADES, make sure
teeth face down toward the table. The
force of the cut is always down. Make sure
the blade is properly tensioned.
5. CUTS SHOULD ALWAYS BE FULLY
SUPPORTED by the table or some type of
support fixture. Always support round stock
in a V-block.
6. DO NOT BACK WORKPIECE AWAY from
the blade while the saw is running. Plan
your cuts so you always cut out of the
wood. If you need to back the work out,
turn the bandsaw off and wait for the blade
to come to a complete stop. Do not twist or
put excessive stress on the blade while
backing work away.
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 bandsaws. Accidents are frequently caused by lack of familiarity or failure to
pay attention. Use this tool with respect and
caution to lessen the possibility of operator
injury. If normal safety precautions are overlooked or ignored, serious personal injury
may occur.
G1073/G1073Z 16'' Bandsaw -5-
220V Operation
The Model G1073/G1073Z Bandsaw is supplied
with a dual-voltage 110V/220V motor, prewired
for 220V operation. Under normal use, the motor
draws approximately 12 amps at 220V. We recommend a 15 amp circuit breaker or slow-blow
fuse for 220V. This should be satisfactory for normal use, while providing enough protection
against damage caused by an overloaded circuit.
If frequent circuit failures occur when using the
bandsaw, contact our service department or your
local electrical contractor.
The Model G1073/G1073Z Bandsaw is not supplied with a power plug. We recommend using a
NEMA-style L6-15 plug and outlet similar to the
one shown in Figure 1. You may also “hard-wire”
the bandsaw directly to your panel, provided you
place a disconnect near the machine.
110V Operation
If 110 volt operation is desired, refer to the wiring
diagram in the back of this manual. Under normal
use, the motor draws approximately 24 amps at
110V. We recommend using a circuit breaker and
wires rated for 30 amps. This should be satisfactory for normal use, while providing enough protection against damage caused by power surges.
If frequent circuit failures occur when using the
bandsaw, contact our service department or your
local electrical contractor.
The Model G1073/G1073Z is not supplied with a
power plug. It will be necessary to supply your
own standard 110V, 30 Amp grounded plug and
receptacle as shown in Figure 2.
SECTION 2: CIRCUIT REQUIREMENTS
Figure 1. Typical 220V 3-prong plug and outlet.
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, make sure the cord is rated Hard
Service (Grade S) or better. Refer to the chart on
page 3 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
Be sure that your particular electrical configuration complies with local and state codes.
The best way to ensure compliance is to
check with your local municipality or
licensed electrician.
-6- G1073/G1073Z 16" Bandsaw
Figure 2.
Under no circumstances should the grounding
pin from any three-pronged plug be removed. If it
will not fit the outlet, have the proper outlet
installed by a qualified electrician.
Check with a qualified electrician or one of our
service personnel if the grounding instructions
are not completely understood, or if you are in
doubt as to whether the tool is properly grounded.
Use only 3-wire extension cords that have 3prong grounding type plugs and 3-hole receptacles that accept the tool’s plug, similar to that in
Figure 2.
Repair or replace damaged or worn cords immediately.
Grounding
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric
shock. This tool is equipped with an electric cord
having an equipment grounding conductor. A
plug with a grounding pin must be plugged into a
matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
Improper connections of the electrical-grounding
conductor can result in risk of electric shock. The
conductor with green or green and yellow striped
insulation is the electrical grounding conductor. If
repair or replacement of the electric cord or plug
is necessary, do not connect the equipment
grounding conductor to a live terminal.
We have covered some basic electrical
requirements for the safe operation of your
bandsaw. 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.
This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug into is actually
grounded. Under no circumstances should the
grounding pin from any
three-pronged plug be
removed. Serious injury
may occur.

Clean up Site Considerations
1. Floor Load: Your Model G1073/G1073Z 16''
Bandsaw represents a large weight load in a
small footprint. Most commercial floors are
suitable for the Model G1073/G1073Z. Some
residential floors may require additional build
up to support both machine and operator.
2. 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 bandsaw.
3. Lighting and Outlets: Lighting should be
bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be
dedicated or large enough to handle amperage requirements. Outlets should be located
near each machine so power or extension
cords are clear of high-traffic areas. Observe
local electrical codes for proper installation
of new lighting, outlets, or circuits.
The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. Avoid chlorinebased solvents as they may damage painted
surfaces should they come in contact. Always
follow the usage instructions on the product you
choose for clean up.
Do not use gasoline or
other petroleum-based
solvents to clean with.
They have a low flash
point which makes them
extremely flammable. A
risk of explosion and
burning exists if these
products are used.
Serious personal injury
may occur.
Make your shop “child safe.”
Ensure that your workplace
is inaccessible to children
by closing and locking all
entrances when you are
away. Never allow visitors in
your shop when assembling,
adjusting, or operating
equipment.
Do not smoke while using
solvents. A risk of explosion or fire exists and may
result in serious personal
injury.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingested. Always work in wellventilated areas far from
potential ignition sources
when dealing with solvents. Use care when disposing of waste rags and
towels to be sure they do
not create fire or environmental hazards.

SECTION 4: ASSEMBLY
Figure 3. Attaching motor mount bracket.
Figure 4. Motor attached to motor mount bracket.
Stand (G1073)
The stand assembly on the Model G1073 is
shown here. If you have the Model G1073Z, follow the same instructions for mounting the motor,
bandsaw to stand, and the anti-vibration pads.
Disregard the steps that do not apply.
To ease assembly, build the stand upside down
on a bench, then place it upright on the floor. Do
not fully tighten any of the bolts until directed to
do so in the next section.
Sometimes sheet metal parts have a tendency to
''spring'' after they are formed. For this reason,
you may need to use a little extra force to align
holes to insert bolts.
2. Position the motor so the pulley is over the
rectangular hole in the stand top as shown in
Figure 4. Secure with four (4)
5
⁄16"-18 x 1"
carriage bolts,
5
⁄16" washers, and 5⁄16"-18 nuts
provided.
To assemble the stand:
1. Flip the top of the stand upside-down.
Position the motor mounting bracket so that
it sits over the four (4) evenly spaced holes
in the top. Bolt the bracket to the stand with
two (2)
3
⁄8"-16 x 1" hex bolts, 3⁄8" washers,
and
3
⁄8"-16 nuts provided. Hand tighten for
now so your assembly looks like Figure 3.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Wear safety glasses during the entire assembly
process. Failure to comply may result in serious
personal injury.
Disconnect power to the
machine when performing any maintenance or
assembly. Failure to do
this may result in serious
personal injury.

Figure 5. Legs and braces attached to top.
3. Attach the four (4) legs to the inside of the
stand top and the four horizontal braces to
the inside of the legs as shown in Figure 5.
Use the
5
⁄16"-18 x 5⁄8" carriage bolts, 5⁄16"-18
nuts, and
5
⁄16" washers provided. The two
shorter braces are slightly wider than the
longer braces. When attaching the braces to
the legs, the longer braces rest inside the
two flanges of the shorter braces. The
square holes in the legs are angled to
accommodate the angle of the legs.
4. Attach the four (4) rubber feet to the legs.
Use four (4)
5
⁄16"-18 x 1" hex head bolts, four
(4)
5
⁄16" flat washers and four (4) 5⁄16"-18 nuts
provided. The bolts should go through the
pad first and then through the feet. Tighten
carefully so you do not deform the rubber
feet.
5. Slide the motor pulley onto the motor shaft
and tighten the setscrew down. The small
end of the pulley should be near the motor.
6. Flip the stand/motor assembly rightside-up
on the floor, but do not tighten the stand
hardware at this time.

Bandsaw Mounting Holes
Bandsaw To Stand
1. Safely lift the bandsaw onto the stand.
Ensure that the bandsaw step pulley is positioned over the hole in the stand.
2. Attach the bandsaw to the stand with four (4)
3
⁄8"-16 x 2" hex bolts, four (4) 3⁄8"-16 hex nuts,
and eight (8)
3
⁄8" washers provided. The bolts
on the left side should go through the motor
mount bracket. Hand tighten for now.
3. Position the bandsaw on the stand so that
the legs are evenly balanced and the stand
is symmetrical in appearance, rather than
lopsided. When the stand is positioned correctly on all four sides, tighten all the stand
nuts to secure it in place.
4. Working from the bottom up, tighten all stand
bolts, motor mount bracket to the stand top
(leave the motor bolts loose for now), and
the bandsaw mounting bolts at the holes
shown in Figure 6.
The bandsaw (without stand
and motor) weighs approximately 325 lbs. Use a lifting
device or get help from people who can safely lift that
much weight. Serious personal injury may occur if
this warning is ignored.

pulley aligns with the motor pulley. Leave the
motor mount bolts loose.
2. Slide the motor up or down to achieve prop-
er V-belt tension. You should be able to
deflect the V-belt about
3
⁄4" at its midpoint
(see Figure 9B) using moderate finger pressure. Be careful not to change the lateral
position of the motor and move the pulleys
out of alignment. Tighten the motor mount
bolts.

3. Check the pulley alignment with a plumb bob
or straightedge. If you are using a plumb
bob, the string must touch the outside
flanges of each pulley evenly as shown in
Figure 10, and the machine must be level.
4. Check V-belt tension. Repeat steps 1-4 until
both tension and pulley alignment are correct.
