Laser Guide
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.
DO NOT look directly into laser. Severe eye
injury will result.
To adjust laser:
1. DISCONNECT DRILL PRESS FROM
POWER!
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.
2. Install drill bit in chuck (see Installing/
Removing Drill Bits on Page 25 of Model
G7944 manual).
3. Clamp workpiece securely to table.
4. Adjust table so workpiece is within range of
drill bit, then lock table in horizontal position.
5. Lower drill bit so it touches workpiece, making a slight indentation in the surface, then
raise bit.
6. Connect drill press to power. Turn laser
ON using switch on front of drill press (see
Figure 1).

Wiring Safety Instructions
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 components!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpredictable results, including serious injury or fire.
This includes the installation of unapproved aftermarket parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires disconnected 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 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
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.

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, such as acetone or brake
parts cleaner, as they may damage painted surfaces should they come in contact. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
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.
Floor Load
Refer to the Machine Data Sheet for weight and
footprint specifications for your machine. Some
residential floors may require additional reinforcement 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.

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 suggest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application.
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 washers, and hex nuts.

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 1
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.

Choosing Speeds
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.

Changing Speeds
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.
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.
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.
Figure 26. Loosening lock knob (both sides).
3. Rotate the belt tension lever clockwise, as
shown in Figure 27, to take tension off the
V-belts.
• 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.

Drilling
SOFT MATERIAL: The softer the material, the
faster the spindle may turn. (Plastics can melt at
too high of a spindle speed!)
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 placing 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.
LUBRICANT: Use some form of lubricant on
all materials except wood. Refer to Lubrication
Suggestions on Page 26 to find the correct lubrication for your application.
DRILLING ACCURACY: To prevent drill bit wandering 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, carbide-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 cutter 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 plastic 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.
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.
-28-
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.
Model G7943/G7944 (Mfg. 10/02+)
Depth Stop
Adjusting Table
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.

Arbor Removal
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 different 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.

SECTION 6: MAINTENANCE
Unpainted Cast Iron
Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious personal injury.
Protect the unpainted cast iron surfaces by wiping them clean after every use—this ensures
moisture from wood dust does not remain on bare
metal surfaces.
General
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.
Cleaning
Keep these surfaces rust-free with regular applications of products like G96
SLIPIT
ACCESSORIES on Page 31 for more details).
®
, or Boeshield® T-9 (see SECTION 5:
®
Gun Treatment,
Lubrication
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.
V-Belts
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.
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.

Depth Stop
Feed Shaft Spring
Calibration
The drill press comes fitted with a depth stop
to use when drilling multiple holes at the same
depth. The scale on this depth stop can be
calibrated if it ever becomes incorrect.
To calibrate the depth stop:
1. Loosen the jam nut and calibration nut shown
in Figure 46.
Stop
Bracket
Jam Nut
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.
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!
2. Wipe off any oil on the spring lock cover so it
does not slip in your fingers when you hold the
cover from spinning (see Figure 47).
Calibration
Nut
Figure 46. Depth stop assembly.
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
jam nut to hold the depth stop in position.
4. Test the depth stop by measuring how far the
spindle actually moves with respect to where
you set the depth stop.

3. While holding the spring lock cover against
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.
Figure 48. Example of loosening cover and jam
nut.
A high tension coiled spring is underneath
the cover. Put on heavy leather gloves to
protect yours hands from possible lacerations when removing the cover.
8. Snug the cover nut against the spring cover
just until the nut stops, and then back off
1
the nut approximately
⁄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.
