Safety for Drill Presses
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.
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.
2. SECURING BIT. Properly tighten and
securely lock the drill bit in the chuck.
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.
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.
10. MAINTENANCE/SPEED
CHANGES.
Never do maintenance or change speeds
with the machine plugged in.
5. DRILLING SHEET METAL. Never drill
sheet metal unless it is securely clamped
to the table.
11. MOUNTING WORKPIECES. Use clamps
or vises to secure workpiece before drill-
ing. Position work so you avoid drilling into
the table.
6. SURFACE/WORKPIECE PREP. 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 support is
used.
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.
7. DAMAGED TOOLS. Never use tools in
poor condition. Dull or damaged cutting
tools are hard to control and may cause
serious injury.
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 per-
sonal injury, damage to equipment, or poor
work results.
Like all machines there is danger associated
with this machine. Accidents are frequently
caused by lack of familiarity or failure to pay
attention. Use this machine with respect
and caution to lessen the possibility of
operator injury. If normal safety precautions
are overlooked or ignored, serious personal
injury may occur.

Grounding
Extension Cords
In the event of an electrical short, grounding
reduces the risk of electric shock. The grounding
wire in the power cord must be properly connect-
ed to the grounding prong on the plug; likewise,
the outlet must be properly installed and ground-
ed. All electrical connections must be made in
accordance with local codes and ordinances.
110V Operation
We do not recommend the use of extension
cords. Instead, arrange the placement of your
equipment and the installed wiring to eliminate
the need for extension cords.
If you find it absolutely necessary to use an
extension cord at 110V with your machine:
•
•
•
Use at least a 10 gauge cord that does not
exceed 50 feet in length!
Electrocution or fire could
result if this machine is
not grounded correctly or
if your electrical configu-
ration does not comply
with local and state codes.
Ensure compliance by
checking with a qualified
electrician!
The extension cord must also contain a
ground wire and plug pin.
A qualified electrician MUST size cords over
50 feet long to prevent motor damage.
220V Operation
We do not recommend the use of extension
cords. Instead, arrange the placement of your
equipment and the installed wiring to eliminate
the need for extension cords.
If you find it absolutely necessary to use an
extension cord at 220V with your machine:
•
•
•
Use at least a 12 gauge cord that does not
exceed 50 feet in length!
The extension cord must also contain a
ground wire and plug pin.
A qualified electrician MUST size cords over
50 feet long to prevent motor damage.
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.

Clean Up
Site Considerations
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.
Floor Load
Refer to the Machine Data Sheet for weight and
footprint speciifcations 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 G7947/G7948.
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.

5. Tilt the entire assembly up (see Figure 12)
and carefully position the drill press on its
base in the fully upright position.
Headstock
Components and Hardware Needed:
Qty
Headstock ..........................................................1
If the base starts to slide when tilting, you
MUST have a third person hold the base
from sliding to avoid personal injury or
machine damage.
The headstock must be mounted on the col-
umn/base assembly before the drill press can be
operated. Moving and installing the headstock is
a two-person job, at the very least. Although the
headstock can be lifted directly onto the column
while upright, doing so is difficult and potentially
dangerous because of the heavy weight involved.
We recommend sliding the column into the head-
stock, then tilting the entire assembly fully upright,
as described and shown in this section.
The headstock is very
heavy. You MUST have
assistance when moving,
lifting or mounting the
headstock on the column
and base assembly.
To mount the headstock onto the column:
1. Set the top piece of the headstock styrofoam
packing approximately six feet away from the
column/base assembly.
2. Remove the headstock from the box and
place it on the styrofoam packing piece you
laid out in Step 1.
Note: To avoid damaging the machine, be
careful not to hold the headstock by the
switch or the top part of the belt cover when
lifting.

as shown in Figure 13.
Drill Chuck & Arbor
The drill chuck attaches to the spindle by means of
the arbor, shown in Figure 15. Matched tapers on
the arbor and the inside of the chuck create a semi-
permanent assembly when properly joined.

To assemble the drill chuck and mount it to
the spindle:
1. Use mineral spirits to thoroughly clean the drill
chuck, arbor, and spindle sockets and dry all
surfaces before assembly. Follow all safety
warnings on the container of the mineral
spirits. Failure to clean the mating surfaces
may cause the tapered fit to loosen during
operation, resulting in separation and an
unsafe condition.
2. Use the chuck key to adjust the jaws of the
drill chuck until they are inside the drill chuck
body.
3. Place the drill chuck face down on a
workbench. The arbor has a short taper and
a long taper. Place the short taper into the
socket in the back of the drill chuck and tap it
with a rubber or wooden mallet, as shown in
Figure 16. If the chuck fails to remain secure
on the arbor, repeat Steps 1 & 2.

Test Run
Floor Mounting
Once assembly is complete, you are ready to test
run the drill press.
Once you have confirmed that your machine
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 22) 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.
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.
To test run the drill press:
1. Turn the power supply ON at the main
Figure 22. Typical concrete mounting hardware.
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.
Mobile Base
Mounting
Because the drill press is top-heavy by nature, we
recommend mounting it to the floor, rather than a
mobile base.
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.
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 24.
A good quality base plate increases the standard
footprint of the drill press to make it much more
1
stable. The base plate must be at least 1 ⁄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.
Always use extreme care when moving the drill
press around with the mobile base!
-24-

7. Place the drill press on the base plate.
8. Position the drill press close to the front of the
mobile base, so the mobile base will not be a
tripping hazard.
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.
9. Mount the drill press to the base plate with
lag bolts and flat washers (Figure 24); or with
through bolts, flat washers, and hex nuts.
Needed Materials for Base Plate

•
•
Plywood 3⁄4" x 233⁄4" x 233⁄4"........................ 2
Wood Glue ................................. As Needed
Wood Screws #6 x 11⁄4"............................ 24
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
placing the drill press on it.
Figure 24. Drill press mounted on mobile base,
using a base plate for support.
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.
Recommended
Adjustments
6. Secure the base plate to the mobile base
with hex bolts, hex nuts, flat washers and
lock washers, as shown in Figure 23.
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.

Choosing Speeds
Using the Drill Bit Speed Chart
Lubrication Suggestions
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.
Wood ...........................................................None
Plastics ........................................... Soapy Water
Brass .............................. Water-Based Lubricant
Aluminum......................Paraffin-Based Lubricant
Mild Steel..............................Oil-Based Lubricant
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.
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.
Often, when drilling materials other than wood,
some type of lubrication is necessary.

SOFT MATERIAL: The softer the material, the
faster the spindle may turn. (Plastics can melt at
too high of a spindle speed!)
Drilling
The Model G7947/G7948 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.
LUBRICANT: Use some form of lubricant on
all materials except wood. Refer to Lubrication
Suggestions on Page 27 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.
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.
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.
SECURING WORKPIECE TO TABLE: Secure
the workpiece to the table or in a vise that is
secured to the table before drilling.
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.
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.
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.
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 27 to help you
choose the correct speed for your application.
LARGE DIAMETER BITS: Large diameter drill
bits require slower spindle speeds.
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.
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.

Depth Stop
Adjusting Table
The Model G7947/G7948 has a depth stop that
allows you to drill repeated non-through holes to
the same depth every time.
The table can raised/lowered, rotated, and tilted
90° left or right. Table adjustment controls are
shown in Figure 30.
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.

Table Tilt
3. Lower the jam nut against the depth nut.
1. Tighten the location pin nut to draw the loca-
tion pin out of the hole. Note: The location
pin is friction fit in the hole to lock the table at
0°. When reinstalling, set the table to 0°, back
the nut off, and tap the pin back in the hole.
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.
2. Loosen the lock bolt and tilt the table to the
desired angle (make sure table rotation lock
knob is locked, so the table won't fall out).
3. Tighten the lock nut bolt.

7. Hold the drill chuck with one hand, and tap
on the drift key with a rubber or wooden
mallet, as shown in Figure 32, until the
chuck releases.
Arbor Removal
The arbor can be removed to install other Morse
Taper tooling in the spindle. A drift key is included
to help remove the arbor or other tooling 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.)
8.
Hold a downfeed handle with one hand, and
loosen the depth stop lock with the other
hand.
9.
Carefully retract the quill into the head
stock.
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. Rotate the depth stop hub clockwise until it
stops.
4. Tighten the lock knob. The quill should not
return up into the head casting when the
depth stop is adjusted this way.
5. Rotate the spindle until the inner drift-key slot
is aligned with the outer slot, as shown in
Figure 31. You will see through the spindle
when the slot is properly aligned.

Depth Stop
Calibration
Feed Shaft Spring
Tension
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.
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.
To calibrate the depth stop:
1. Loosen the jam nut and calibration nut shown
in Figure 41.
Wear safety glasses when
adjusting springs. Serious
injury may occur if this
warning is ignored!
To adjust the feed shaft spring tension:
