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’s safer than using your
hand and frees both hands to operate tool.
13. DO NOT OVER-REACH. Keep proper
footing and balance at all times.

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.

G8976 3 Wheel 12" Bandsaw -7-
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.
NOTICE
The wire on the power cord with green or
green and yellow striped insulation is the
grounding conductor.

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.
