The laser should be checked and adjusted before
starting a new project, and any time you raise or
lower the table, or change workpiece thickness.
Laser Guide 7. Adjust laser (Figure 2), positioning it by hand
so crosshairs align with indentation you made
earlier in surface of workpiece, as shown in
Figure 3.
DO NOT look directly into laser. Severe eye
injury will result.
To adjust laser:
1. DISCONNECT DRILL PRESS FROM
POWER!
2. Install drill bit in chuck (see Installing/
Removing Drill Bits on Page 25 of Model
G7944 manual).

WIRING
SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical com-
ponents!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpre-
dictable results, including serious injury or fire.
This includes the installation of unapproved after-
market parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires dis-
connected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious per-
sonal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.
MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.
CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
EXPERIENCING DIFFICULTIES. If you are expe-
riencing difficulties understanding the information
included in this section, contact our Technical
Support at (570) 546-9663.

Safety Instructions for Machinery
17. REMOVE ADJUSTING KEYS AND
WRENCHES. Make a habit of checking for
keys and adjusting wrenches before turn-
ing machinery ON.
18. CHECK FOR DAMAGED PARTS
BEFORE USING MACHINERY. Check
for binding and alignment of parts, broken
parts, part mounting, loose bolts, and any
other conditions that may affect machine
operation. Repair or replace damaged

mended accessories. The use of improper
accessories may cause risk of injury.
20. DO NOT FORCE MACHINERY. Work at
the speed for which the machine or acces-
sory was designed.
21. SECURE WORKPIECE. Use clamps or
a vise to hold the workpiece when practi-
cal. A secured workpiece protects your
hands and frees both hands to operate the
machine.
22. DO NOT OVERREACH. Keep proper foot-
ing and balance at all times.
23. MANY MACHINES WILL EJECT
WORKPIECE TOWARD OPERATOR.
Know and avoid conditions that cause the
workpiece to "kickback."
24. ALWAYS LOCK MOBILE BASES
(IF USED) BEFORE OPERATING
MACHINERY.
25. BE AWARE THAT CERTAIN WOODS
MAY CAUSE AN ALLERGIC REACTION
in people and animals, especially when
exposed to fine dust. Make sure you
know what type of wood dust you will be
exposed to and always wear an approved
respirator.
Model G7943/G7944 (Mfg. 10/02+) -11-
1. EYE/FACE/HAND PROTECTION. A face
shield used with safety glasses is rec-
ommended. Always keep hands and fin-
gers away from the drill bit. Never hold a
workpiece by hand while drilling! DO NOT
wear gloves when operating the drill.
2. SECURING BIT. Properly tighten and
securely lock the drill bit in the chuck.
3. CORRECT BIT. Use only round, hex, or
triangular shank drill bits.
4. ADJUSTING KEYS AND WRENCHES.
Remove all adjusting keys and wrenches
before turning the machine ON.
5. DRILLING SHEET METAL. Never drill
sheet metal unless it is securely clamped to
the table.
6. SURFACE /WORKPIECE PREPARATION.
Never turn the drill press ON before clearing
the table of all objects (tools, scrap wood,
etc.) DO NOT drill material that does not
have a flat surface, unless a suitable sup-
port is used.
7. DAMAGED TOOLS. Never use tools in poor
condition. Dull or damaged cutting tools
are hard to control and may cause serious
injury.
Safety for Drill Presses
8. DRILL OPERATION. Never start the drill
press with the drill bit pressed against the
workpiece. Feed the drill bit evenly into the
workpiece. Back the bit out of deep holes.
Turn the machine OFF and clear chips and
scrap pieces with a brush. Shut power OFF,
remove drill bit, and clean table before leav-
ing the machine.
9. OPERATING SPEED. Always operate your
drill press at speeds that are appropriate
for the drill bit size and the material that you
are drilling.
10. MAINTENANCE/SPEED CHANGES.
Never do maintenance or change speeds
with the machine plugged in.
11. MOUNTING WORKPIECES. Use clamps
or vises to secure workpiece before drill-
ing. Position work so you avoid drilling into
the table.
12. TABLE LOCK. Make sure the table lock is
tightened before starting the drill press.
13. EXPERIENCING DIFFICULTIES. If at
any time you are experiencing difficulties
performing the intended operation, stop
using the machine! Contact our Service
Department at (570) 546-9663.

Floor Load
Refer to the Machine Data Sheet for weight and
footprint specifications for your machine. Some
residential floors may require additional reinforce-
ment to support both the machine and operator.
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 machine. See Figure 5 for the minimum
working clearances of the Model G7943/G7944.
Unsupervised children and
visitors inside your shop
could cause serious per-
sonal injury to themselves.
Lock all entrances to the
shop when you are away and
DO NOT allow unsupervised
children or visitors in your
shop at any time!
The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during ship-
ment. Remove this protective coating with a sol-
vent 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, such as acetone or brake
parts cleaner, as they may damage painted sur-
faces should they come in contact. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
Site ConsiderationsClean Up
Gasoline and petroleum
products have low flash
points and could cause
an explosion or fire if
used to clean machinery.
DO NOT use gasoline or
petroleum products to
clean the machinery.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest-
ed. Lack of ventilation
while using these sol-
vents could cause seri-
ous personal health risks
or fire. Take precautions
from this hazard by only
using cleaning solvents
in a well ventilated area.

Test Run
Wear safety glasses
whenever starting or
using machine. Failure
to comply may result in
serious personal injury.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Once assembly is complete, you are ready to test
run the drill press.
To test run the drill press:
1. Turn the power supply ON at the main
panel.
2. With your finger poised on the paddle
switch (in case there is a problem), flip the
START button ON. The drill press should run
smoothly, with little or no vibration or rubbing
noises.
Investigate and correct for strange or unusual
noises before operating the machine further.
If you cannot easily locate the source of a
potential problem, refer to Troubleshooting
on Page 35. If you still can't solve the
problem, contact our Technical Support at
(570) 546-9663.
Use only bulbs that are “safety coated” and
shatter resistant. The bulb will be exposed
at the bottom of the head casting which
helps with illumination. Impacts with a bulb
not “safety coated” may shatter, expos-
ing the electrical filaments and creating an
electrical shock hazard.

To mount the G7943 drill press to a table:
1. Clamp the base on a bench top capable
of holding approximately 160 lbs. plus the
weight of the workpiece using two clamps.
Make sure the surface is flat and stable.
2. Using holes in the base as a guide (Figure
20), drill and bolt the base to the bench top
using lag bolts, or carriage bolts, flat wash-
ers, and hex nuts.
Mounting Floor Mounting
Once you have confirmed that your Model G7944
is running properly, we strongly recommend
mounting it to the floor to ensure optimum
stability.
Lag shield anchors with lag bolts and anchor
studs (Figure 21) are two popular methods for
anchoring an object to a concrete floor. We sug-
gest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application.
Figure 21. Typical concrete mounting hardware.
Mobile Base Mounting
Because the Model G7944 drill press is top-heavy
by nature, we recommend mounting it to the floor,
rather than a mobile base.
If you must use a mobile base, ALWAYS mount
your drill press to a base plate inside of the mobile
base, as shown in Figure 23.
A good quality base plate increases the standard
footprint of the drill press to make it much more
stable. The base plate must be at least 11⁄2" thick
and made of plywood (do not use OSB, MDF,
or particle board) to hold the weight of the drill
press. A common way for making the baseplate is
described in this sub-section.

For your convenience, the adjustments listed
below have been performed at the factory; how-
ever, because of the many variables involved
with shipping, we recommend that you at least
verify the following adjustments before operating
your machine—this will ensure that you know the
operating tolerances of your machine, and you
have them adjusted to your expectation.
Step-by-step instructions for these adjustments
can be found in SECTION 7: SERVICE.
Factory adjustments that should be verified:
1. Depth Stop Calibration (Page 38)
2. Feed Shaft Spring Tension (Page 38)

• Wood Screws #6 x 11⁄4" ............................ 24
• Mounting Hardware ............................ Varies
To make and use the base plate:
1. Glue the two pieces of plywood together,
and align the edges and corners so the two
boards make one thick piece.
2. Use the wood screws to fasten the boards
together from both sides.
3. Allow 24 hours for the glue to dry before plac-
ing the drill press on it.
4. Place the base plate on the mobile base.
5. Drill holes through the base plate and the
metal plates at the corners of the mobile
base.
6. Secure the base plate to the mobile base with
hex bolts, hex nuts, flat washers and lock
washers, as shown in Figure 22.
Drill presses are top-heavy and must be
securely attached to a large-footprint base
plate when used with a mobile base. Failure
to use a base plate greatly increases pos-
sibility of tipping and personal injury.

Using the Drill Bit Speed Chart
The chart shown in Figure 25 is intended as
a guide only. Always follow the manufacturer's
speed recommendations if provided with your
drill bits, cutters, or hole saws. Exceeding the
recommended speeds may be dangerous to the
operator.
The speeds shown here are intended to get you
started. The optimum speed will always depend
on various factors, including tool diameter, drilling
pressure, material hardness, material quality, and
desired finish.
Often, when drilling materials other than wood,
some type of lubrication is necessary.
Lubrication Suggestions
Wood ...........................................................None
Plastics ........................................... Soapy Water
Brass .............................. Water-Based Lubricant
Aluminum ......................Paraffin-Based Lubricant
Mild Steel ..............................Oil-Based Lubricant
Larger bits turning at slower speeds tend
to grab the workpiece aggressively. This
can result in the operator's hand being
pulled into the bit or the workpiece being
thrown with great force. Always clamp the
workpiece to the table to prevent injuries.

Figure 26. Loosening lock knob (both sides).
Figure 27. Using the belt tension lever.
The belts in the head of the drill press must be
rearranged to change speeds. A chart under the
belt cover shows the belt positions needed to
make the drill press run at the desired speed.
To change speeds:
1. UNPLUG THE DRILL PRESS!
2. Loosen the belt tension lock knobs (shown in
Figure 26) on both sides of the headstock,
so the motor is free to move.
Changing Speeds
3. Rotate the belt tension lever clockwise, as
shown in Figure 27, to take tension off the
V-belts.
4. Locate the desired speed on the speed chart
under the belt cover and move the V-belts
to the desired V-grooves on the motor, idler,
and spindle pulleys.
For Example: As indicated in the speed chart
for 540 RPM (Figure 28), a belt combination
of A-1, 2-2 creates 540 RPM.
• The “A-1” refers to the belt position between
the spindle pulley and the idler pulley.
• The “2-2” refers to the belt position between
the motor pulley and the idler pulley.
Note: Both belts may have to be removed
before certain speed changes can be made.
Figure 28. Pulley combination for 540 RPM for

5. Rotate the belt tension lever until the belts
are tight. Tighten both lock knobs.
6. Close the cover before plugging in the
machine.
-28- Model G7943/G7944 (Mfg. 10/02+)
The Model G7943/G7944 is designed for drilling
holes in wood or metal. The basic operation
of a drill press is lining up your drill bit with the
intended hole location, turning the drill press
ON, and using the down feed levers to move the
spinning drill bit into the workpiece.
For safe operation and optimum results, it
is very important to follow these guidelines
when drilling:
CLEARING CHIPS: Raise the drill bit often to
clear chips and cool the drill bit. This will ease the
work of the drill press motor and extend the life of
your drill bits.
SECURING WORKPIECE TO TABLE: Secure
the workpiece to the table or in a vise that is
secured to the table before drilling.
PROTECTING TABLE: Protect the table by plac-
ing the workpiece on scrap wood, or center the
location of the hole to be drilled over the pocket in
the table when through drilling. Also, make use of
the depth stop so that the drill bit goes no deeper
than necessary.
USING CORRECT SPEEDS: Use the correct
speed for the diameter of the drill bit being used
and the type of material being drilled. Refer to the
Drill Bit Speed Chart on Page 26 to help you
choose the correct speed for your application.
LARGE DIAMETER BITS: Large diameter drill
bits require slower spindle speeds.
SMALL DIAMETER BITS: Smaller diameter drill
bits require faster spindle speeds.
HARD MATERIAL: The harder the material,
(steel vs. wood) the slower the spindle speed.
Drilling
Larger bits turning at slower speeds tend
to grab the workpiece aggressively. This
can result in the operator's hand being
pulled into the bit or the workpiece being
thrown with great force. Always clamp the
workpiece to the table to prevent injuries.
SOFT MATERIAL: The softer the material, the
faster the spindle may turn. (Plastics can melt at
too high of a spindle speed!)
LUBRICANT: Use some form of lubricant on
all materials except wood. Refer to Lubrication
Suggestions on Page 26 to find the correct lubri-
cation for your application.
DRILLING ACCURACY: To prevent drill bit wan-
dering and ensure accurate placement of holes,
mark the hole location with a center punch before
drilling. Also consider using a center-point drill to
start the hole.
PLUG/ROSETTE CUTTERS: Plug cutters and
rosette cutters are for wood only. However, car-
bide-tipped bits and cutters cut at a higher speed
and can cut materials other than wood, depending
on the cutter type.
5-FLUTE/2-FLUTE CUTTERS: Use a 5-flute cut-
ter when cutting into plastics, brass, aluminum,
and mild steel. A 2-flute cutter can aggressively
grab the workpiece and damage the tool if used
with materials other than wood.
SPADE BITS AND PLASTIC: When drilling plas-
tic with a spade bit, use a spade bit with spurs.
HOLE SAWS: When using hole saws, apply firm
and even pressure, so the saw teeth contact the
surface all at the same time—not at an angle. You
can also flip the workpiece and finish drilling from
the other side.

Figure 29. Depth stop components.
Depth Nut Jam Nut
Depth
Stop Stud
The Model G7943/G7944 has a depth stop that
allows you to drill repeated non-through holes to
the same depth every time.
The depth stop consists of a stud attached to the
quill with two hex nuts that can be lowered or
raised on the stud so the lower nut (depth nut)
hits a stop bracket when the drill bit is lowered.
The upper hex nut (jam nut) is then used to
tighten against the depth nut to secure it in place
so it doesn't move with repeated operations.
Figure 29 shows the various components of the
depth stop.
Depth Stop
To set the depth stop:
1. Lower the drill bit to the required height.
2. Thread the depth nut down against the stop
bracket.
3. Lower the jam nut against the depth nut.
4. Using wrenches, hold the depth nut in place
and tighten the jam nut against the depth
nut.
Note: The scale on the depth stop can be recali-
brated if it gets moved or has changed since the
factory setting. Refer to Calibrating Depth Stop
on Page 38 for instructions on how this is done.

The arbor can be removed to install another drill
chuck in the spindle. A drift key is included to help
remove the arbor from the spindle. Usually, once
the chuck and arbor have been properly mounted
together, they are considered semi-permanent
connections. (If you would like to install a differ-
ent chuck, we recommend getting a new arbor for
that chuck.)
To remove the drill chuck and arbor:
1. UNPLUG THE DRILL PRESS!
2. Rotate the spindle handles until the drift-key
slot is exposed in the side of the quill.
3. Loosen the lock knob and rotate the hub
(Figure 31) clockwise until it stops.

Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious person-
al injury.
Cleaning the Model G7943/G7944 is relatively
easy. Vacuum excess wood chips and sawdust,
and wipe off the remaining dust with a dry cloth.
If any resin has built up, use a resin dissolving
cleaner to remove it. Treat all unpainted cast
iron and steel with a non-staining lubricant after
cleaning.
Cleaning
SECTION 6: MAINTENANCE
Protect the unpainted cast iron surfaces by wip-
ing them clean after every use—this ensures
moisture from wood dust does not remain on bare
metal surfaces.
Keep these surfaces rust-free with regular appli-
cations of products like G96® Gun Treatment,
SLIPIT®, or Boeshield® T-9 (see SECTION 5:
ACCESSORIES on Page 31 for more details).
Unpainted Cast Iron
Lubrication
V-Belts
Since all bearings are shielded and permanently
lubricated, simply leave them alone until they
need to be replaced. DO NOT lubricate them.
Keep quill, spindle, column, and table top well
lubricated to prevent rust.
Inspect regularly for tension and wear. Check
pulleys to ensure that they are properly aligned.
See Changing Speeds on Page 26 for more
information about removing/installing belts if you
need help replacing the belts.
Regular periodic maintenance on your drill press
will ensure 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:
• Loose mounting bolts.
• Worn switch.
• Worn or damaged cords and plugs.
• Damaged V-belt.
• Any other condition that could hamper the
safe operation of this machine.

calibrated if it ever becomes incorrect.
To calibrate the depth stop:
1. Loosen the jam nut and calibration nut shown
in Figure 46.
Depth Stop
Calibration
2. Use the calibration nut to zero the depth stop
scale with the stop bracket.
3. Hold the depth stop at zero, and tighten the

4. Test the depth stop by measuring how far the
spindle actually moves with respect to where
you set the depth stop.
Feed Shaft Spring
Tension
The feed shaft return spring is adjusted at the
factory; however, during the life of the drill press
you may want to adjust the feed shaft return
spring so the feed shaft return pressure suits your
operating needs.
Figure 47. Feed shaft return spring assembly.
Wear safety glasses when
adjusting springs. Serious
injury may occur if this
warning is ignored!
To adjust the feed shaft spring tension:
1. UNPLUG THE DRILL PRESS!

the side of the headstock so the cover stays
splined with the locking lug; loosen the jam
nut and loosen the cover nut approximately
1⁄4" (see Figure 48).
4. Put on heavy leather gloves to protect your
hands from possible lacerations if the spring
uncoils during the next step.
5. Pull the cover outward just enough to
disengage the spring-cover lock slot from the
locking lug. Note: It is important to keep a
good grip during this step. Letting go of the
cover will cause the spring to rapidly uncoil.
6. Rotate the cover counterclockwise to increase
spring tension, or let the cover slowly unwind
in the clockwise direction to reduce spring
tension.
7. Engage the next available spring-cover lock
slot with the locking lug and hold the spring
lock cover tightly against the side of the
headstock.
8. Snug the cover nut against the spring cover
just until the nut stops, and then back off
the nut approximately 1⁄3 turn, or just enough
so there is no binding at complete spindle
travel.
9. Hold the cover nut and tighten the jam nut
against the cover nut.
A high tension coiled spring is underneath
the cover. Put on heavy leather gloves to
protect yours hands from possible lacera-
tions when removing the cover.

SECTION 8: WIRING
Wiring Safety Instructions
1. SHOCK HAZARD. Working on wiring that
is connected to a power source is extremely
dangerous. Touching electrified parts will
result in personal injury including but not lim-
ited to severe burns, electrocution, or death.
Disconnect the power from the machine
before servicing electrical components!
2. QUALIFIED ELECTRICIAN. Due to the
inherent hazards of electricity, only a quali-
fied electrician should perform wiring tasks
on this machine. If you are not a quali-
fied electrician, get help from one before
attempting any kind of wiring job.
3. WIRE CONNECTIONS. All connections
must be tight to prevent wires from loosen-
ing during machine operation. Double-check
all wires disconnected or connected during
any wiring task to ensure tight connections.
4. WIRE/COMPONENT DAMAGE. Damaged
wires or components increase the risk of
serious personal injury, fire, or machine
damage. If you notice that any wires or
components are damaged while performing
a wiring task, replace those wires or compo-
nents before completing the task.
5. MODIFICATIONS. Using aftermarket parts or
modifying the wiring beyond what is shown
in the diagram may lead to unpredictable
results, including serious injury or fire.
6. MOTOR WIRING. The motor wiring shown
in these diagrams is current at the time of
printing, but it may not match your machine.
Always use the wiring diagram inside the
motor junction box.
7. CAPACITORS. Some capacitors store an
electrical charge for up to five minutes after
being disconnected from the power source.
To avoid being shocked, wait at least this
long before working on capacitors.
8. CIRCUIT REQUIREMENTS. You MUST fol-
low the requirements on Page 12 when con-
necting your machine to a power source.
9. EXPERIENCING DIFFICULTIES. If you are
