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.
Minimum Gauge for Extension Cords
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.
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.
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. 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

Safety Instructions For Power Tools
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.
19. NEVER LEAVE TOOL RUNNING UNAT-
TENDED. TURN POWER OFF. Do not
leave tool until it comes to a complete stop.
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.
21. NEVER ALLOW UNSUPERVISED OR
UNTRAINED PERSONNEL TO OPER-
ATE THE MACHINE. Make sure any
instructions you give in regards to machine
operation are approved, correct, safe, and
clearly understood.
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.

Additional Safety Instructions For Horizontal
Boring Machines
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.
6. ALWAYS FEED BITS EVENLY AND
SMOOTHLY. Do not force bit while boring.
7. BIT(S) SHOULD BE RUNNING AT FULL
SPEED before beginning to bore.
8. ALL INSPECTIONS, ADJUSTMENTS,
AND MAINTENANCE ARE TO BE DONE
WITH THE POWER OFF AND THE
MACHINE DISCONNECTED FROM THE
POWER SOURCE. Wait for all moving
parts to come to a complete stop.
9. HABITS – GOOD AND BAD – ARE HARD
TO BREAK. Develop good habits in your
shop and safety will become second-
nature to you.
1. DO NOT OPERATE WITH DULL OR
BADLY WORN BITS. Dull bits require
more effort to use and are difficult to con-
trol. Inspect bits before each use.
2. NEVER POSITION FINGERS OR
THUMBS IN LINE WITH THE AIR-POW-
ERED CLAMP. Serious personal injury
could occur.
3. DO NOT OPERATE THIS HORIZONTAL
BORING MACHINE WITHOUT GUARDS
IN PLACE.
4. WHEN REPLACING BITS, make sure
they are properly inserted and tightened.
5. BORING SHOULD ALWAYS BE FULLY
SUPPORTED by the table or some type of
support fixture.

SECTION 2: CIRCUIT REQUIREMENTS
220V Operation
The Model G4185 has a 2 H.P., 3450 R.P.M.
motor which requires a 220V single-phase circuit.
The cord set enclosed does not have a plug as
the style of plug you require will depend upon the
type of service you currently have or plan to
install. The motor will safely draw about 12 amps
at 220V under load. If you operate the Model
G4185 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 power failure still occurs, have the cir-
cuit inspected by a qualified electrician.
Circuit Load
When operating at 220V, we recommend using a
NEMA-style 6L-15 plug and outlet. See Figure 1.
You may also “hard-wire” the machine directly to
your panel, provided you place a disconnect
switch near the machine. Check the electrical
codes in your area for specifics on wiring require-
ments.
Under normal use, the motor draws approximate-
ly 12 amps at 220V. We recommend a 15 amp cir-
cuit breaker for 220V operation This should be
satisfactory for normal use while providing
enough protection against circuit damage caused
by power surges.
Figure 1. Typical 220V 3-prong plug and outlet

-6- Model G4185 Horizontal Boring Machine
We do not recommend the use of extension cords
on 220V equipment. It is much better to 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
Instructions 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.
Extension Cords
Your Model G4185 comes pre-wired for 220 volt
operation. A wiring diagram is provided at the
back of this manual should it be necessary to
repair or revise the wiring. Always utilize a quali-
fied electrician when doing any electrical work on
this equipment.
Wiring Diagram
We have covered some basic electrical
requirements for the safe operation of your
machine. These requirements are not nec-
essarily 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.
Grounding
In the event of an electrical short, grounding pro-
vides electric current a path of least resistance to
reduce the risk of electric shock. This tool is
equipped with an electric cord having an equip-
ment-grounding conductor which must be proper-
ly 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 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 cir-
cumstances should the
grounding pin from any
three-pronged plug be
removed. Serious injury
may occur.

Model G4185 Horizontal Boring Machine -9-
Clean 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. 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.
Site Considerations
FLOOR LOAD
Your Model G4185 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 G4185. If you question the
strength of your floor, you can opt to have it rein-
forced by a qualified contractor.
WORKING CLEARANCES
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. Also consider the relative
position of each machine to one another for effi-
cient material handling. Be sure to allow yourself
sufficient room to safely run your machines in any
foreseeable operation.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate
shadows 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.
Do not smoke while using
solvents. A risk of explo-
sion or fire exists and may
result in serious personal
injury.
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 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.

Model G4185 Horizontal Boring Machine
All die-cut metal parts have a sharp edge
(called “flashing”) on them after they are
formed. This is removed at the factory.
Sometimes, though, a bit of flashing might
escape inspection. Please examine the
edges of all die-cut metal parts before han-
dling them or serious injury may occur.
Disconnect power to the
machine when perform-
ing any maintenance,
assembly or adjust-
ments. Failure to do this
may result in serious
personal injury.

Model G4185 Horizontal Boring Machine -13-
Checking Air Lines
The Model G4185 uses air pressure to clamp
workpieces. Air consumption is .5 cubic feet per
minute (CFM). All air lines should be checked for
possible crimping damage in shipping or unpack-
ing.
Check air lines in all areas that pass over rigid
materials, such as cast iron and sheetmetal. Also
check where curves in the lines are tight. If there
is any sign of wear or crimping, replace the appro-
priate air hose. See Figure 9.
FIGURE 9. Air lines that pass over cast iron cor-
ners and other tight radii should be free of kinks.
Miter Gauge
The miter gauge for the Model G4185 is a dove-
tailed type. It must be inserted into the dovetailed
grooves on the edge of the table. See Figure 10.

SECTION 6: OPERATIONS
Here are a few simple things you can do to
increase the predictability of your horizontal bor-
ing machine’s performance:
1. Use the right bit for the job. Bits are the
screw-in type and are specifically made for
horizontal boring machines.
2. Never rush a drilling proceedure. Extra care
during set up will ensure satisfactory
results.
3. Maintain your horizontal boring machine in
top condition. See Section 7 of this manual
for maintenance procedures.
4. Always use a test piece of wood to check
your set up. Only when desired results are
achieved should you use your expensive
lumber.
A horizontal boring machine bit requires proper
care.
1. Store the bits so their sharp points and flutes
are protected. A wooden or plastic box that
keeps bits from touching one another works
best.
2. Keep bits clean and rust free.
3. Have bits sharpened as soon as they show
any signs of dulling.
