Safety Instructions For Power Tools
9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condi-
tion. Conductor size should be in accor-
dance 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 exten-
sion cords if they become damaged.
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 recon-
necting.
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, bind-
ing 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.

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 cov-
ering to contain long hair.
19. NEVER LEAVE TOOL RUNNING UNAT-
TENDED. TURN POWER OFF. Do not
leave tool until it comes to a complete stop.
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.
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.
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.
21. NEVER ALLOW UNSUPERVISED OR
INEXPERIENCED PERSONNEL TO
OPERATE THE MACHINE. Make sure
any instructions you give in regards to
machine operation are approved, correct,
safe, and clearly understood.
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 lubri-
cating and changing accessories.
22. IF AT ANY TIME YOU ARE EXPERIENC-
ING DIFFICULTIES performing the intend-
ed operation, stop using the machine!
Then contact our service department or
ask a qualified expert how the operation
should be performed.
15. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recom-
mended accessories. The use of improper
accessories may cause risk of injury.

Additional Safety Instructions For Drill Presses
1. ALWAYS OPERATE YOUR DRILL PRESS AT SPEEDS that are appropriate for the drill bit size
and the material that you are drilling.
2. FEED THE DRILL BIT EVENLY INTO THE WORKPIECE. Back the bit out of deep holes and clear
the chips with a brush after you have turned the machine off.
3. MAKE SURE THE DRILL BIT YOU ARE USING IS TIGHTENED PROPERLY. Use only round,
hex or triangular shank drill bits.
4. NEVER DO MAINTENANCE OR CHANGE SPEEDS WITH THIS MACHINE PLUGGED IN.
5. NEVER USE TOOLS THAT ARE IN POOR CONDITION. Cutting tools that are dull or damaged
are difficult to control and may cause serious injury.
6. NEVER DRILL SHEET METAL UNLESS IT IS CLAMPED SECURELY TO THE TABLE.
7. WORK SHOULD BE POSITIONED IN SUCH A WAY AS TO AVOID DRILLING INTO THE
TABLE.
8. A FACE SHIELD USED WITH SAFETY GLASSES IS RECOMMENDED.
9. ALWAYS CLAMP WORKPIECE SECURELY TO TABLE BEFORE DRILLING. Never hold a
workpiece by hand while drilling.
10. HABITS – GOOD AND BAD – ARE HARD TO BREAK. Develop good habits in your shop and
safety will become second-nature to you.
11. REMOVE ADJUSTING KEYS AND WRENCHES. Before turning the machine on, make it a habit
to check that all adjusting keys and wrenches have been removed.
No list of safety guidelines can be com-
plete. 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 equip-
ment or poor work results.

SECTION 2: CIRCUIT REQUIREMENTS
110V Operation
This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug into is actually
grounded. Under no cir-
cumstances should the
grounding pin from any
three-pronged plug be
removed or serious injury
may occur.
The Model G7945/46 is wired for 110V, single
phase operation only. The 1⁄2 HP motor will safely
draw 5 amps at 110V. If you operate this machine
on any circuit that is already close to its capacity,
it might blow a fuse or trip a circuit breaker.
However, if an unusual load does not exist and a
power failure still occurs, contact a qualified elec-
trician or our service department.
A 10-amp fuse or circuit breaker should be used
when fusing this drill press. Circuits breakers
rated any higher may not be adequate to protect
the circuit from power surges.
Extension Cords
If you find it necessary to use an extension cord
with the Model G7945/7946, make sure the cord
is rated Hard Service (grade S) or better. Refer to
the chart in the standard safety instructions to
determine the minimum gauge for the extension
cord. The extension cord must also contain a
ground wire and plug pin.
Figure 1A. Do not remove grounding pin.
Grounding
In the event of an electrical short, grounding
reduces the risk of electric shock by providing
electric current a path of least resistance. This
tool is equipped with a power cord having an
equipment-grounding conductor. See Figure 1.
The outlet must be properly installed and ground-
ed in accordance with all local codes and ordi-
nances.

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 chlorine-based
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.
FLOOR LOAD
Your Model G7945/46 represents a moderate
weight load in a small footprint. Most commercial
or home shop floors should be sufficient to carry
the weight of the Model G7945/46. If you question
the strength of your floor, you can opt to reinforce
it. Ensure that the stand or bench you use with the
Model G7945 is capable of supporting the
machine.
WORKING CLEARANCES
Do not use gasoline or
other petroleum-based
solvents. They have low
flash points which make
them extremely flamma-
ble. A risk of explosion
and burning exists if
these products are
used. Serious personal
injury may occur if this
warning is ignored.
Working clearances can be thought of as the dis-
tances between machines and obstacles that
allow safe operation of every machine without lim-
itation. Consider existing and anticipated machine
needs, size of material to be processed through
each machine, and space for auxiliary stands
and/or work tables. Be sure to allow yourself suf-
ficient room to safely run your machines in any
foreseeable operation.
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.
Many of the solvents commonly used to
clean machinery can be toxic when inhaled
or ingested. Always work in well-ventilated
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 environmen-
tal hazards. Keep children and animals
safely away when cleaning and assembling
this machine.
Make your shop “child
safe.” Ensure that your
workplace is inaccessible
to youngsters by closing
and locking all entrances
when you are away. Never
allow visitors in your shop
when assembling, adjust-
ing or operating equip-
ment.
Do not smoke while using
solvents. A risk of explo-
sion or fire exists and may
result in serious personal
injury.

SECTION 4: ASSEMBLY
Beginning Assembly
Do not use a mobile
base. Drill presses
are extremely top
heavy. A stable base
is required to prevent
serious bodily injury.
Disconnect power to the
machine when perform-
ing any maintenance,
assembly or adjust-
ments. Failure to do this
may result in serious
personal injury.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Wear safety glasses dur-
ing the entire assembly
process. Failure to com-
ply may result in serious
personal injury.

Headstock
Drill Chuck and Arbor
1. Make sure the locking gib is in the recessed
pocket on the inside edge of the headstock
opening. See Figure 8.
The drill chuck is attached to the drill spindle by
means of a machined taper between the chuck
and spindle nose. An almost permanent assem-
bly is created when properly joined. To assemble
the drill chuck and mount it to the spindle, care-
fully follow the instructions below:
2. With the help of an assistant, lift the headstock
over the top end of the column. When the
underside of the headstock is lined up with the
column, slide the headstock onto the column
until it stops (approximately 2").
1. The drill chuck and spindle must be thor-
oughly cleaned and dried before assembly. It
is recommended that mineral spirits be used
for this task. Refer to the safety warnings on
the container of the mineral spirits. Failure to
clean the mating surfaces may result in
separation, and an unsafe condition.
Separation is usually a result of oil or
grease on the taper.
3. Screw two lock handles into each side of the
headstock bracket. See Figure 8.
The headstock repre-
sents a heavy load. Seek
assistance before begin-
ning this step.
2. Use the chuck key provided to adjust the
jaws of the chuck until they are well inside
the drill chuck body.
3. Slide the chuck onto the spindle end and tap
the end of the drill chuck with a rubber or
wooden mallet to seat it. See
Figure 9.
DO NOT use a steel hammer on the drill
chuck to seat it onto the spindle. Damage
will occur to the chuck and/or spindle
which may make them unusable or unsafe.

SECTION 6: OPERATIONS
Test Run
Drill Bit Changes
Care must be taken to secure the bit firmly in
place. When changing bits, proceed as follows:
Disconnect power to the
machine when perform-
ing any maintenance,
assembly or adjust-
ments. Failure to do this
may result in serious
personal injury.
1. Disconnect the machine from the power
source.
2. Open the chuck wide enough to accept a
new bit.
3. Install the bit so the chuck jaws will grab as
much of the bit shank as possible. Do not
allow the chuck to grab the fluted body of the
drill bit. Make sure small drill bits do not get
trapped between the edges of two jaws.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
4. Tighten the chuck with the chuck key using
any of the three key end locations.
5. Remove the chuck key and reconnect the
power source.
Wear safety glasses
during the entire opera-
tion process. Failure to
comply may result in
serious personal injury.
6. Reverse steps to remove the drill bit.
Once assembly is complete and adjustments are
done to your satisfaction, you are ready to test run
the machine.
Turn on the power supply at the main panel.
Press the START button. Make sure that your fin-
ger is poised on the paddle switch, just in case
there’s a problem. The drill press should run
smoothly, with little or no vibration or rubbing nois-
es. Strange or unnatural noises should be investi-
gated and corrected before operating the
machine further.
If you cannot easily locate the source of an
unusual noise or vibration, contact our service
department for help.

SECTION 7: MAINTENANCE
Tables
Disconnect power to the
machine when perform-
ing any maintenance,
assembly or adjust-
ments. Failure to do this
may result in serious
personal injury.
The nonpainted surfaces on the Model G7945/46
should be protected against rust and pitting.
Wiping the machine clean after every use ensures
that wood dust will not trap moisture against bare
metal surfaces.
Some woodworkers recommend using automo-
tive paste wax on exposed steel and cast iron sur-
faces. The wax provides a layer of protection, as
well as reducing friction between lumber and the
table, making cuts faster and smoother. Avoid
waxes that contain silicone or other synthetic
ingredients. These materials can find their way
into lumber that is being worked, and can make
staining and finishing difficult. If you use paste
wax, make sure that it is 100% Carnauba wax.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Wear safety glasses dur-
ing the entire mainte-
nance process. Failure
to comply may result in
serious personal injury.
General
Lubrication
Regular periodic maintenance on your Model
G7945/46 will ensure its optimum performance.
Make a habit of inspecting your machine each
time you use it. Check for the following conditions
and repair or replace when necessary:
Since all bearings are shielded and permanently
lubricated, simply leave them alone until they
need to be replaced. Do not lubricate them.
1. Loose mounting bolts.
2. Worn switch.
V-Belt
3. Worn or damaged cords and plugs.
4. Damaged V-belt.
Inspect regularly for tension and wear. Check pul-
leys to ensure that they are properly aligned. See
pulley/V-belt sections for proper tension and pul-
ley alignment procedures.
5. Any other condition that could hamper the
safe operation of this machine.

We have included some important safety mea-
sures that are essential to this machine’s opera-

universal, Grizzly reminds you that each work-
shop is different and safety rules should be con-
sidered as they apply to your specific situation.
The Model G7945/46 was specifically
designed for drilling operations. DO NOT
MODIFY AND/OR USE THIS MACHINE FOR
ANY OTHER PURPOSE. Modifications or
improper use of this tool will void the war-
ranty. If you are confused about any aspect
of this machine, DO NOT use it until all your
questions have been answered or serious
personal injury may occur.
Operating this equipment has the potential
for flying debris to cause eye injury. Always
wear safety glasses or goggles when oper-
ating equipment. Everyday glasses or read-

es, they are not safety glasses. Be certain
the safety glasses you wear meet the appro-
priate standards of the American National
Standards Institute (ANSI).
Like all power tools, there is danger asso-
ciated with the Model G7945/46. Accidents
are frequently caused by lack of familiarity
or failure to pay attention. Use this tool
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored,
serious personal injury may occur.
