Safety Instructions For Power Tools
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.
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.
14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for lubricating and changing accessories.
15. DISCONNECT TOOLS before servicing
and changing accessories, such as blades,
bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off
position before plugging in.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recommended accessories. The use of improper
accessories may cause risk of injury.
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 USE UNDER THE INFLUENCE of
alcohol or drugs, or when tired.
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. NEVER OVERREACH. Keep proper foot-
ing and balance at all times.
G8621 Heavy-Duty Sliding Table Shaper-3-
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 Shapers
1.NEVER ALLOW YOUR HANDS to come
within 12 inches of the cutters. Never pass
your hands directly over or in front of the
cutter.
2.BLIND CUT WHENEVER POSSIBLE. This
keeps the knives on the underside of the
workpiece and provides a distance guard
for the operator.
3.WHEN SHAPING CONTOURED WORK
and using a rub collar, NEVER start out at a
corner. See the “Rub Collar” instructions
further on in the manual.
4.WITH THE MACHINE UNPLUGGED,
always rotate the spindle by hand with any
new setup to ensure proper cutter clearance
before starting the machine.
5.DO NOT SHAPE STOCK SHORTER than
12 inches without special fixtures or jigs.
Where practical, shape longer stock and cut
to size.
6.NEVER ATTEMPT to remove too much
material in one pass. You are far more likely to enjoy safer and higher quality results if
you allow the cutter to remove material in
multiple passes.
7.THE DANGER OF kickback is increased
when the stock has knots, holes, or foreign
objects in it. Warped stock should be run
through a jointer before attempting to run it
through a shaper.
8.KEEP THE UNUSED PORTION of the cutter below the table surface.
9.THE USE OF PUSH STICKS as safety
devices in some applications is smart; in
others it can be quite dangerous. If the push
stick comes in contact with the cutter on the
end grain, it can fly out of your hand like a
bullet—potentially causing serious injury.
We recommend using some type of fixture,
jig, or hold-down device as a safer alternative. Always use the guard as described in
the manual.
10. NEVER FORCE MATERIALS through the
shaper. Let the cutters do the work.
Excessive force is likely to result in poor cutting results and will cause dangerous kickback conditions.
11. ALWAYS ensure that the cutters, fence,
and spindle elevator knob have been tightened properly before beginning any operation.
12. ALWAYS feed the work toward the cutters
in the direction opposite of the cutter rotation. Also, using and maintaining a sharp
cutterhead will greatly reduce the chance of
kickback.
13. NEVER REACH BEHIND CUTTER to grab
the workpiece. Your hand may suddenly be
pulled into the cutter in the event of a kickback.
14. IF AT ANY TIME YOU ARE EXPERIENCING DIFFICULTIES PERFORMING THE
INTENDED OPERATION, STOP USING
THE SHAPER! Then contact our service
department or ask a qualified expert how
the operation should be performed.
Like all power tools, there is danger associated with shapers. 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.
-4-G8621 Heavy-Duty Sliding Table Shaper
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.
SECTION 2: CIRCUIT REQUIREMENTS
220V Operation
The Model G8621 Shaper is furnished with a
3450 R.P.M., 5 H.P., Single-Phase 220V motor,
push-button ON/OFF magnetic starter switch, forward-reverse switch and a cord set. Under normal use, the motor draws approximately 25 amps
@ 220V. We recommend a 30 amp circuit breaker. If frequent circuit failures occur when using the
shaper, contact our service department.
The shaper motor must be connected to its own
dedicated 30A circuit. The shaper should not
share a circuit with any other machine, and the
wires in the circuit should be rated for 30A. A
standard 2-pole breaker is also necessary for use
with the shaper.
We recommend using a NEMA-style L6-30 plug
and outlet similar to that in Figure 1. You may
also “hard-wire” the shaper directly to your panel,
provided you place a disconnect near the
machine. Check the electrical codes in your area
for specifics on wiring requirements.
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 an electric cord
that has an equipment-grounding conductor
which must be properly connected to a grounding
plug. The plug 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 the 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.
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.

G8621 Heavy-Duty Sliding Table Shaper-5-
Extension Cords
Wiring
We do not recommend the use of extension
cords on 220V equipment. 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 in Section 1: Safety 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.
A wiring diagram is provided at the back of this
manual should it be necessary to repair or revise
the wiring. Always utilize a qualified electrician
when doing any electrical work on this equipment.
We have covered some basic electrical
requirements for the safe operation of
your machine. 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.

Clean Up
Site Considerations
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
to clean.
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.
Serious personal injury
may occur.
FLOOR LOAD
Your Model G8621 Shaper represents a moderately large weight load in a moderate sized footprint. Most commercial shop floors will be adequate for the 770 lb. weight of the Model G8621.
Some floors may require additional support.
Contact an architect or structural engineer if you
have any question about the ability of your floor to
handle the weight.
WORKING CLEARANCES
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 and/or work tables. Also consider the relative position of each machine to one another for
efficient material handling. Be sure to allow yourself sufficient room to safely run your machines in
any foreseeable operation.
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.
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
combined motor amp loads. Outlets should be
located near each machine so power or extension cords are not obstructing high-traffic areas.
Be sure to 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.

SECTION 4: ASSEMBLY
Beginning Assembly
Most of your Model G8621 Shaper has been
assembled at the factory, but some parts must be
assembled or installed after delivery. We have
organized the assembly process into steps.
Please follow along in the order presented here.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Disconnect power to the
machine when performing any maintenance or
assembly. Failure to do
this may result in serious
personal injury.
Handwheel
The handwheel, pre-installed at the factory, is
made of cast iron. It is used to raise and lower the
spindle to accommodate the height required by
your cutter.
Thread the crank handle onto the handwheel.
