ELECTRICAL REQUIREMENTS
Connecting tool to power source outlet: This machine’s power source must be grounded
while in use to protect the operator from electric shock.
In the event of a malfunction or breakdown, grounding provides a path of least resistance
for electrical current to reduce the risk of electric shock. This tool is equipped with an
electric cord that has an equipment grounding conductor that is properly installed and
grounded in accordance with all local codes and ordinances.
Improper connection of the equipment grounding conductor can result in a risk of electric
shock. The conductor with the green insulation (with or without yellow stripes) is the
equipment 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.
Plug power cord into a 110-120V properly grounded type outlet protected by a 14 amp
time delay, Circuit Saver fuse or circuit breaker.
WARNING: Do not let your fingers touch the terminals of plug when installing or removing
the plug to or from the outlet.
WARNING: If not properly grounded, this power tool can incur the potential hazard of
electric shock; particularly when used in damp locations or in close proximity to plumbing.
If an electric shock occurs, there is the potential of a secondary hazard – such as your
hands contacting the grinding wheel.
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated
in Figure A. The tool has a grounding plug that also looks like the one shown in Figure A.
Do not modify the plug provided if it will not fit the outlet. Have the proper outlet installed
by a qualified electrician.

EXTENSION CORDS
1. Use only 3-wire extension cords which have 3 prong grounding type plugs and 3
prong receptacles which accept the tool’s plug. Replace or repair damaged or worn
cords immediately.
2. Only UL listed extension cords should be used with this product.
3. Improper use of extension cords may cause inefficient operation of your tool which
can result in overheating. Be sure your extension cord is rated to allow sufficient
current flow to the motor. For the proper gauge for your tool, see chart.

Installing the Lights
MAKE CERTAIN THAT THE BENCH GRINDER IS TURNED OFF AND UNPLUGGED
Locate the 2 15 watt light bulbs (included) and install them into the sockets at the end of
each flexible light arm. Turn bulb clockwise until it is secure.
Changing Accessories
MAKE CERTAIN THAT THE BENCH GRINDER IS TURNED OFF AND UNPLUGGED
USE ONLY GRINDING WHEELS THAT MEASURE 6 INCHES IN DIAMETER. THIS
TOOL HAS 1/2 INCH ARBORS ON BOTH SIDES.
Follow the steps presented below to remove and replace any accessory.
1. Raise the eye shield up, out of the way.
2. Loosen and pull the tool rest out as far as possible. Do not remove it.
3. Remove the screws from the side of the wheel cover and remove cover.
OPERATION
ALWAYS WEAR EYE PROTECTION WHEN USING THE GRINDER.
Keep a steady, moderate pressure on the work piece and keep it moving at an even pace
for smooth grinding. Pressing too hard overheats the motor and prematurely wears down
the grinding wheels, so take your time. Note the original bevel angle on the item to be
sharpened and try to maintain this shape. The grinding wheel should rotate into the object
being sharpened. Keep a tray filled with water and dip your work into it regularly to prevent
overheating. Overheating can weaken metals.
SCISSORS
If possible, take the scissors apart to make the sharpening operation easier and safer.
7
Remove material only from the outside surface and work from the heavy end of the blade
toward the tip.
KNIVES
Remove metal from both faces of most knives, working from the heavy end of the blade
toward the tip.
SCREWDRIVERS
The end of a properly sharpened screwdriver will be a perfect rectangle, absolutely flat
and perpendicular to the center line of the shank. The two sides and two faces will taper
outward from the edge of the shoulder or shank. They should be flat with intersecting
faces perpendicular. Hold each face of the screwdriver against the wheel to true it up, and
then ease the end straight into the stone to grind it true.
TWIST DRILL BITS
Drill bits are best sharpened on a sharpening jig, available at most hardware stores, but
can be “dressed up” on your bench grinder. Begin on one side of the point at the existing
angle, and then twist the bit while maintaining a constant angle with grinding surface.
Sharpen only the tip. This technique requires considerable practice, so take your time and
make a few “dry runs” first with the grinder off. Be sure to maintain the original cutting
edge angle as this is important to the efficiency of your bits. One tool rest has a V-groove
that is correctly angled for most drill bits.
LAWN MOWER BLADES
Lawn mower blades are usually sharpened on only one side and dressed up slightly on
8
the other. After sharpening, be sure to balance the blade by removing additional material
from the heavy end. There are a number of inexpensive cone balances on the market for
this purpose. Unbalanced blades can cause serious crank shaft damage to your lawn
mower. Always remove spark plug wires from the mower before servicing the blades to
prevent accidental starting.
MAINTENANCE
WARNING: For your own safety, turn switch OFF and remove plug from power source
outlet before adjusting and maintaining your bench grinder. If power cord is worn, cut, or
damaged in any way, have it replaced immediately.
CARE OF GRINDING WHEELS
In normal use, grinding wheels may become cracked, grooved, rounded at the edges,
chipped, out of true or loaded with foreign material. CRACKED WHEELS SHOULD BE
REPLACED IMMEDIATELY, while any of the other conditions can be remedied with a
dressing tool (available at most hardware stores). New wheels sometimes require
dressing to make them round.
WHEEL REPLACEMENT
If you must replace a wheel be sure to obtain one with a safe rated speed at least as high
as the ‘NO LOAD’ RPM marked on your grinder’s nameplate and with a 1/2” center hole.
6” diameter wheel should be a maximum of 3/4” wide. Test new wheels for cracks and
maintain the existing sequence of retaining hardware. Be sure the tool is unplugged
before attempting repairs.
Your bench grinder will accept most polishing and buffing wheels available at dealers and
hardware stores.
WARNING: The use of any other accessories is not recommended and may result in
serious injury.
