accident prevention measures.
NOTICE
24" & 27" Resaw Bandsaws -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 UNINTENTION-
AL 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 further 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
8. ALWAYS FEED STOCK EVENLY AND
SMOOTHLY. Do not force or twist blade
while cutting, especially when sawing
small radii.
9. THIS MACHINE IS NOT DESIGNED TO
CUT METAL or other material except
wood.
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 second-nature to you.
13. IF AT ANY TIME YOU ARE EXPERIENC-
ING 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 after installing.
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.
7. BLADE SHOULD BE RUNNING AT FULL
SPEED before beginning a cut.
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.
To operate this or any power tool safely and
efficiently, it is essential to become as familiar with it as possible. The time you invest
before you begin to use your bandsaw will
be time well spent. DO NOT operate this
machine until you are completely familiar
with the contents of this manual or serious
personal injury may occur.
SECTION 2: CIRCUIT REQUIREMENTS
Model G3619
The Model G3619 Bandsaw is pre-wired for single-phase, 220V operation. Under normal use, the
Model G3619 5 HP motor draws approximately
22 amps. We recommend a 30 amp circuit. This
includes a 30 amp circuit breaker and wiring rated
for at least 30 amps. 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.
This bandsaw must be connected to its own
dedicated circuit; it should not share a circuit with
any other machine. A standard 2-pole breaker is
necessary for use with the Model G3619.
This bandsaw is not supplied with a power plug.
We recommend using a NEMA-style L6-30 plug
and outlet similar to Figure 1. You may also “hard-
wire” the bandsaw directly to your panel, provided
you place a disconnect near the machine.
Model G9963
The Model G9963 Bandsaw is pre-wired for
single-phase, 220V operation. Under normal use,
the Model G9963 7.5 HP motor draws approxi
mately 33 amps. We recommend using a 50 amp
circuit. This includes a 50 amp circuit breaker
and wiring rated for at least 50 amps. If frequent
circuit failures occur when using the bandsaw,
contact our service department or your local electrical contractor.
This bandsaw must be connected to its own
dedicated circuit; it should not share a circuit with
any other machine. A standard 2-pole breaker is
necessary for use with the Model G9963.
This bandsaw is not supplied with a power plug.
We recommend “hard-wiring” the bandsaw to the
power source, provided you place a locking shut
off switch near the machine to disconnect the
power.
-
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 a
licensed electrician.

The Model G3620/G9966 Bandsaw is pre-wired
for 3-phase, 220V operation. Under normal use,
1
⁄2 HP motor for this model draws approxi-
the 7
mately 19 amps. We recommend using a 25 amp
circuit, including a 25 amp circuit breaker and wir
ing rated for at least 25 amps. If frequent circuit
breaker failures occur when using the bandsaw,
contact our service department.
This bandsaw must be connected to its own
dedicated circuit. It should not share a circuit with
any other machine. A standard 3-pole breaker is
necessary for use with the Model G9963.
We recommend using a NEMA-style L15-30
plug and outlet, similar to Figure 2. You may
also “hard-wire” the bandsaw directly to your
panel, provided you place a disconnect near the
machine. Check the electrical codes in your area
for specifics on wiring requirements.
The Model G3620/G9966 Bandsaw is furnished
with a 7
to 440V. Under normal use, this motor draws
approximately 10 amps at 440V. If 440V opera
-
tion is desired, we recommend using a 15 amp
circuit that includes the appropriate wiring and
circuit breaker. If frequent circuit failures occur
when using the bandsaw, contact our service
department.
The bandsaw must be connected to its own dedi
cated 10A circuit. It should not share a circuit with
any other machine. A standard 3-pole breaker is
necessary for 440V use.
This bandsaw is not supplied with a power plug.
We recommend “hard-wiring” the bandsaw to the
power source, provided you place a locking shut
off switch near the machine to disconnect the
power. Check the electrical codes in your area for
specifics on wiring requirements.
If you convert the bandsaw to 440V, the stock
mag switch must be replaced with a differ
ent mag switch specifically for 440V use. The
440 mag switch is not included with your
bandsaw.

Under no circumstances should the grounding
pin from any plug be removed. If it will not fit the
outlet, have the proper outlet installed by a qualified electrician. Repair or replace damaged or
worn cords immediately.
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 extension cords that have grounding
type plugs and receptacles that accept the plug
on the machine
.
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.
We do not recommend the use of extension
cords on 220V or 440V 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.

Unpacking
The 24" and 27" Resaw Bandsaws are shipped
from the manufacturer in a carefully packed crate.
If you discover the machine is damaged after you
have signed for delivery, please call Customer
Service immediately for advice.
Save the containers and all packing materials for
possible inspection by the carrier or its agent.
Otherwise filing a freight claim can be difficult.
When you are completely satisfied with the condition of your shipment, you should inventory its
parts.
Some metal parts may
have sharp edges on
them after they are
formed. Please examine
the edges of all metal
parts before handling
them. Failure to do so
could result in injury.
The 24" and 27" Resaw
Bandsaws are heavy
machines. DO NOT
over-exert yourself
while unpacking or
moving your machine –
you will need assistance and power equipment. Serious personal
injury may occur if safe
moving methods are not
followed.
-10- 24" & 27" Resaw Bandsaws
Site Considerations
1. Floor Load: The 24" and 27" Resaw
Bandsaws represent a large weight load in a
small footprint. Most commercial floors are
suitable for your machine. 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.
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.
Clean Up
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. 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 as they may damage painted
surfaces should they come in contact. Always follow the manufacturer’s instructions when using
any type of cleaning product.
Do not use gasoline or
other petroleum-based
solvents to clean with.
They have low flash
points which make them
extremely flammable. A
risk of explosion and
burning exists if these
products are used.
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.

24" & 27" Resaw Bandsaws -15-
G3619/G3620
Tracking
The wheels on the Model G3619/G3620 Resaw
Bandsaws are crowned with rubber tires. This
style requires center tracking for proper operation.
To center track your blade:
1. Make sure the bandsaw is unplugged!
2. Open the upper wheel cover door. Slowly
rotate the upper wheel and watch where the
blade rides on the wheel. If the blade stays
centered on the crown of the wheel, then it is
properly tracked.
3. If the blade does not ride centered on the
crown of the wheel, then spin the upper
wheel by hand and adjust the tracking handwheel until the blade is positioned correctly.
4. Spin the wheel approximately three more
times to ensure that the blade stays centered. Adjust and check if necessary.
5. Close the upper wheel cover door.
G9963/G9966
Tracking
The wheels on the Model G9963/G9966 Resaw
Bandsaws are considered “Flat Wheels.” This
means that tracking procedures vary from the
common crowned wheel bandsaws, because
they do not have to be centered for proper operation.
To track the blade:
1. Make sure the bandsaw is unplugged!
2. Open the wheel cover doors and check the
position of the blade on the wheels. The
teeth of the blade should be over the edge of
each wheel. Ideally, the bottom of the teeth
gullets should ride approximately
1
⁄16" off the
edge of the wheels as shown in Figure 10.
