Additional Safety for Drill Bit Grinders
necktie or loose clothing. Keep long hair away from
Move these types of materials a safe distance away.
The primary risks of operating a Drill Bit Grinder are as follows: You can be blinded or killed
by flying debris created by a chipped or damaged grinding wheel. Your fingers can be cut or
amputated by the rotating grinding wheel. You can also suffer crushing injuries from getting
hair, loose clothing, or jewelry entangled in the wheel. To reduce your risk of serious injury when
operating this machine, completely heed and understand the following.
PERFORM WHEEL INSPECTION. Before
installing a grinding wheel, visually check it for
cracks, chips, nicks or dents in the wheel surface.
Additionally, perform a “ring” test. Do not use the
wheel if it fails inspection.
USE UNDAMAGED WHEELS. Never use a wheel
that has been dropped or received a heavy blow,
even if there is no obvious damage.
SAFELY START UP GRINDER. To protect yourself, always stand to the side of the grinder until the
wheel reaches full speed. Allow it to run for at least
one minute before grinding. If a wheel is damaged,
it will usually fly apart shortly after startup.
USE CORRECT SPEED RATING. Wheels operated at a faster speed than rated for may break or
burst. Before mounting a new wheel, be sure wheel
RPM rating is equal to or higher than speed of
grinder. Never use unmarked wheels.
USE CORRECT WHEEL BORE. Only use wheel
with same bore as machine arbor.
AVOID TOUCHING MOVING WHEEL. Be aware
where your hands are relative to the grinding
wheel, and keep them away from wheel while
grinding.
USE DRILL BIT JIG. Always make sure the drill bit
is properly positioned in the jig, and the jig is firmly
secured to the base, and all locks are tight before
turning the machine ON.
DRY-GRIND ONLY. To avoid the risk of electrocution, do not use fluids of any kind with this
machine. This grinder is designed to perform drygrinding only!
WEAR PROPER CLOTHING. Do not wear gloves,
rotating grinding spindle.
WEAR PROPER PPE. Grinding ejects small particles at a high rate of speed. These particles
can cause blindness, skin injuries, or respiratory
damage. ALWAYS wear approved clothing, safety
goggles or safety glasses with side shields and
face shield, and a respirator appropriate for the
type of grinding to be done.
NEWLY GROUND DRILL BITS WILL BE HOT.
Drill bits can be sharp and get hot during grinding operations. Use leather gloves or shop rags to
protect your hands when installing or removing drill
bits. Remove the gloves before operating.
REDUCE RISK OF FIRE AND EXPLOSIONS.
This machine creates a shower of hot sparks that
can ignite explosive or flammable materials nearby.
PROPERLY MAINTAIN MACHINE. Keep machine
in proper working condition to help ensure all components work as intended and function safely.
Perform routine inspections and all necessary
maintenance, as indicated in owner’s manual.
Never operate machine with damaged or worn
parts that can break during operation.

SECTION 2: POWER SUPPLY
Before installing the machine, consider the availability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
or equipment damage
may occur if machine is
not properly grounded
and connected to power
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid overloading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
For your own safety and protection of
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, consult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power supply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)

Model G0686 (Mfd. Since 01/15)
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is necessary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service personnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with
a new one.
We do not recommend using an extension cord
with this machine.
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
