G8976 3 Wheel 12" Bandsaw
Like all power tools, there is danger associated with the Model G8976. 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.
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.
Additional Safety Instructions For Bandsaws
7. BLADE SHOULD BE RUNNING AT FULL
SPEED before beginning a cut.
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. 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 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. WORKPIECE 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. Inspect blade for damage such as kinks before continuing to use
it. Discard it if necessary.

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 that
has an equipment-grounding prong. The outlet
must be properly installed and grounded in accordance with all local codes and ordinances.
110V Operation
If you find it necessary to use an extension cord
at 110V:
• Make sure the cord is rated Standard Service
(grade S) or better.
• The extension cord must also contain a
ground wire and plug pin.
• Use at least a 16 gauge cord if the cord is 50
feet long or less.
• DO NOT use a cord longer that 100 feet!
Extension Cords
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 a fire
can result if the machine
is not grounded correctly. Make sure all electrical circuits are grounded. Do not use the
machine if it is not
grounded.
No single list of electrical guidelines can
be comprehensive for all shop environments. Operating this machinery may
require additional electrical upgrades specific to your machine and shop environment. It is your responsibility to make sure
your electrical systems comply with all
local electrical codes and ordinances.

Site ConsiderationsClean 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.
Gasoline and petroleum
products have low flash
points and could explode
if used to clean machinery. DO NOT use gasoline or petroleum products to clean the machinery.
Smoking near solvents
could ignite an explosion
or fire and cause serious
injury. DO NOT smoke
while using solvents.
Lack of ventilation while
using solvents could
cause serious personal
health risks, fire, or
environmental hazards.
Always work in a well
ventilated area to prevent the accumulation
of dangerous fumes.
Supply the work area
with a constant source
of fresh air.
Unsupervised children
and visitors inside your
shop could receive serious personal injury.
Ensure child and visitor
safety by keeping all
entrances to the shop
locked at all times. DO
NOT allow unsupervised
children or visitors in the
shop at any time.
Weight Load
The Model G8976 is a small weight load with a
small footprint. Most shop floors and workbenches should be sufficient to carry the weight of the
machine. Reinforce the floor and workbench if
you question its ability to support the weight.
Working Clearance
Working clearances can be thought of as the distances between machines and obstacles that
allow safe operation of every machine without
limitation. Consider existing and anticipated
machine needs, size of material to be processed
through each machine, and space for auxiliary
stands or work tables. Also consider the relative
position of each machine to one another for efficient material handling.
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
the amperage draw. 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.
G8976 3 Wheel 12" Bandsaw -13-
Beginning Assembly
Loose hair and clothing
could get caught in
machinery and cause
serious personal injury.
Keep loose clothing
rolled up and long hair

The blade tracking is primarily affected by the
adjustment of the top wheel. To ensure operator
safety, the blade tracking should be checked
before the machine is operated.
To check and adjust the blade tracking:
1. Disconnect the machine from the power
source!
2. Adjust the upper and lower guide bearings
and support bearings away from the blade.
See “Adjusting Support Bearings” subsection
on page 20 and “Adjusting Guide Bearings”
subsection on page 21 for more information.
3. Remove the side cover if not already done.
4. Loosen the wheel lock knob bolt on the back-
side of the bandsaw (Figure 17).
—If the blade rides in the center of the
upper wheel and is centered on the peak
of the wheel crown, then the bandsaw is
already tracked properly and no further
adjustments are needed at this time.
—If the blade does not ride in the center
of the upper wheel and is not centered on
the peak of the wheel crown, then continue
with the following steps.
6. Use a 3mm Allen wrench to adjust the track-
ing setscrew while spinning the upper wheel.
Adjust the tracking setscrew (Figure 19) until
the blade rides along the center of the bandsaw wheels.
5. Spin the upper wheel by hand at least three
times and watch how the blade rides on the
crown of the wheel. Refer to Figure 18 for an
illustration of this concept.

⁄8".
To perform a resaw cut:
1. Install the widest blade available for your
bandsaw when performing resaw operations. The cut will be straighter and more
accurate. Note—The Model G9173 (
3
⁄8" x
62", 6 TPI) Hook Blade is a good choice for
resawing and it is available in the current
Grizzly Catalog.
2. Adjust the guide post/blade guide assembly
to approximately
1
⁄4" above the top surface of
the workpiece.
3. Joint one face of the workpiece on a jointer.
4. Using a push paddle, slowly feed the work-
piece through the saw blade as shown in
Figure 32. Note—The jointed face of the
workpiece must be against the fence during
this operation.
Crosscutting Resawing
1
⁄4" Gap
G8976 3 Wheel 12" Bandsaw -27-
It is common for a bandsaw blade to wander off
the cut line when sawing (Figure 33). This is
called “blade lead.”
To correct blade lead:
1. Verify that the miter slot and fence are paral-
lel to the side of the blade.
2. Make sure the blade is tracking properly and
that it is correctly tensioned.
3. If the blade tension and tracking are correct-
ly adjusted, and it is not convenient to
replace the blade, compensate for lead by
skewing the fence.
To skew the fence:
1. Obtain a piece of scrap wood that is approx-
imately
3
⁄4" thick x 3" wide x 17" long. On the
wide face of the board, draw a straight line
parallel to the long edge.
2. Slide the fence out of the way and cut free-
hand along the line. Stop at the halfway
point. Turn the bandsaw off and wait for the
blade to stop.
3. Carefully clamp the board to the bandsaw
table.
4. Now, slide the fence over to the board so it
barely touches the edge of the board.
5. Loosen the knob bolt that secures the fence
angle position (
Figure 33
).
6. Skew the fence left or right so it is parallel to
the edge of the scrap piece.
7. While maintaining the skew, tighten the knob
bolt loosened in step 5.

NOTICE
Refer to Figure 36 on page 29 to determine
the best blade for cutting various curves.
When cutting curves, simultaneously feed and
turn the stock carefully so that the blade follows
the layout line without being twisted. If a curve is
so abrupt that it is necessary to repeatedly back
up and cut a new kerf, use either a narrower
blade or a blade with more teeth-per-inch (TPI). A
blade with more TPI can cut relatively tighter
curves, though the cut is usually rougher than
cuts produced by a blade with a medium amount
of TPI.
Always make short cuts first, then proceed to the
longer cuts. Relief cuts will also reduce the
chance that the blade will be pinched or twisted.
Relief cuts are cuts made through the waste portion of the workpiece and are stopped at the cut
line. Make relief cuts from the workpiece edge to
points along the cut line where there are sharp
changes in direction. As you cut along the layout
line, waste wood is released from the workpiece,
alleviating any pressure on the back of the blade.
NOTICE
Relief cuts require you to back the blade
out of the cut. Make relief cuts as short and
straight as possible so the blade only has
a short distance to back out.
Before making stacked cuts, make sure both the
table and the blade are square to one another. If
the table and blade are not square to one another, the cut-out workpieces will not be the same
size.
To perform a stacked cut:
1. Draw the project cut lines on one of the work-
pieces. There should be at least an inch of
scrap area around the outside of the project
cut lines.
2. Stack matching sized workpieces on top of
one another.
3. Secure the workpieces to one another with
hot glue on the sides of the workpiece or
brads in the scrap area on the outside of the
project cut lines.
4. Draw relief lines where the blade or work-
piece may become strained when cutting.
Refer to the previous sub-section, "Cutting
Curves," for more information on relief cuts.
5. Make all of the cuts on the relief cut lines.
6. Cut out the final shape of the workpiece by
cutting along the project cut lines as shown
in Figure 34.
Figure 34. Cutting multiple pieces at once.
Cutting Curves Stacked Cuts
G8976 3 Wheel 12" Bandsaw -29-
The Model G8976 blade speed is variable and
can be adjusted from 50 to 2300 FPM. Blade
speed adjustments are made by turning the blade
speed knob below the power switch (Figure 35).
Figure 35. Blade speed knob.
A combination of factors must be considered
when selecting the correct blade for a particular
cutting operation.
BLADE WIDTH
The Model G8976 can use blades from
1
⁄4" to 3⁄8"
in width. Blade width dictates the largest and
smallest curves that can be cut, as well as how
accurately it can cut a straight line.
• Curve Cutting — Use the chart in Figure 36
to determine the correct blade for curve cutting. Determine the smallest radius curve
that will be cut on your workpiece and use
the corresponding width blade.
• Straight Cutting — Use the largest width
blade that you own.
Figure 36. Determining correct blade
width for cutting various curve sizes.
NOTICE
Cutting with the bandsaw without correctly
adjusting the tracking and tension may
result in the blade falling off the wheels,
causing damage to the machine. Read and
follow the directions in Section 5: Set Up
after changing or adjusting the saw blade.
NOTICE
Most woodcutting can be performed successfully at the higher blade speeds. Slower
blade speeds generally produce better
results when cutting hardwoods, intricate
curves, or when an exceptionally smooth
cut is desired.

G8976 3 Wheel 12" Bandsaw
TOOTH STYLE
Tooth shape, gullet size, and cut angle are all factors that determine the tooth style. Figure 37
illustrates the three main categories of tooth
style.
• RAKER — This style is considered to be the
standard because the tooth size and shape
are the same as the tooth gullet. The teeth
on Raker blades are usually very numerous,
have no angle, and produce cuts by scraping
the material; these characteristics result in
very smooth cuts, but at the same time do
not cut fast and generate more heat while
cutting.These blades also work well for cutting curves.
• SKIP — This style is like a raker blade that is
missing every other tooth. Because of the
design, skip toothed blades have a much
larger gullet than raker blades, and therefore, cut faster and generate less heat.
However, these blades also leave a rougher
cut than raker blades. Great for resawing
and ripping thin stock.
• HOOK — The teeth on this style have a positive angle (downward) which makes them
dig into the material, and the gullets are usually rounded for easier waste removal.
These blades are excellent for the tough
demands of resawing and ripping thick
stock.
Figure 37. Raker, skip and hook tooth styles.
Raker Skip Hook
TOOTH PITCH
Usually measured as TPI, tooth pitch refers to the
number of teeth-per-inch. More teeth-per-inch
(fine pitch) will cut slower, but will produce a
smoother cut; while fewer teeth-per-inch (coarse
pitch) will cut faster, but will produce a rougher
cut.
As a general rule, choose blades that will have at
least three teeth in the cut as shown in Figure 38.
Fewer TPI are best for softer, wetter woods.
Higher TPI are best for harder, drier woods.

workpiece thickness.

G8976 3 Wheel 12" Bandsaw -31-
BLADE BREAKAGE
Many factors can cause a blade to break.
Breakage is often unavoidable because of the
high levels of stress and strain applied to the
blade. Avoidable breakage is usually the result of
improper care or judgement on the part of the
operator when mounting or adjusting the blade or
support guides.
The most common causes of blade breakage
are:
• Incorrect alignment and adjustment of the
blade guides.
• Forcing or twisting a wide blade around a
tight curve.
• Feeding the wood into the blade too fast.
• Using a dull blade.
• Excessive blade tension.
• Top blade guide assembly set too high above
the workpiece.
• Using a blade with a braze or weld that is not
smooth.
BLADE CARE
When taken care of correctly, bandsaw blades
will provide a long usable life. When not handled,
used, cleaned, or stored correctly, blades will
quickly lose their ability to perform accurate and
reliable cuts.
• Handling — Bandsaw blades may become
damaged if they are not handled with care.
Never leave the blade laying on the floor or a
table where it can be stepped on or where
something can be placed on it.
• Usage — Be sure to select blades with the
proper width, style, and pitch for each application. Using the wrong blade will often produce excessive heat which can shorten the
usable life of the blade.
• Cleaning — A clean blade will perform much
better than a dirty blade. Dirty blades pass
through the material being cut with more
resistance than clean blades, causing excessive heat. Cleaners like OxiSolv
®
Blade & Bit
Cleaner are available in the Grizzly catalog.
• Storage — A wall rack is the ideal location for
storing blades.
