MAKE WORKSHOP CHILDPROOF with padlocks and
master switches, or by removing starter keys.
DON’T FORCE TOOL. It will do the job better and safer
at the feed rate for which it was designed.
USE RIGHT TOOL. Don’t force the tool or attachment to
do a job it was not designed for. Don’t use it for a purpose
not intended.
USE THE PROPER EXTENSION CORD. Make sure
your extension cord is in good condition. Use only a
cord heavy enough to carry the current your product
will draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. A wire
gauge size (A.W.G.) of at least 16 is recommended for an
extension cord 25 feet or less in length. If in doubt, use
the next heavier gauge. The smaller the gauge number,
the heavier the cord.
DRESS PROPERLY. Do not wear loose clothing, gloves,
neckties, or jewelry. They can get caught and draw you
into moving parts. Rubber gloves and nonskid footwear
are recommended when working outdoors. Also wear
protective hair covering to contain long hair.
ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impactresistant lenses, they are not safety glasses.
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.
DON’T OVERREACH. Keep proper footing and balance
at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp
and clean for better and safer performance. Follow
instructions for lubricating and changing accessories.
DISCONNECT TOOLS. When not in use, before servicing,
or when changing attachments, blades, bits, cutters, etc.,
all tools should be disconnected.
AVOID ACCIDENTAL STARTING. Be sure switch is off
when plugging in any tool.
USE RECOMMENDED ACCESSORIES. Consult the
operator’s manual for recommended accessories. The
use of improper accessories may risk injury.
NEVER STAND ON TOOL. Serious injury could occur if
the tool is tipped or if the cutting tool is unintentionally
contacted.
CHECK DAMAGED PARTS. Before further 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, binding of moving parts, breakage of
parts, mounting and any other conditions that may affect
its operation. A guard or other part that is damaged must
be properly repaired or replaced by an authorized service
center to avoid risk of personal injury.
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN
THE POWER OFF.
PROTECT YOUR LUNGS. Wear a face or dust mask if
the grinding operation is dusty.
PROTECT YOUR HEARING. Wear hearing protection
during extended periods of operation.
DO NOT ABUSE CORD. Never yank cord to disconnect
from receptacle. Keep cord away from heat, oil, and sharp
edges.
USE OUTDOOR EXTENSION CORDS. When tool is
used outdoors, use only extension cords with approved
ground connection that are intended for use outdoors
and so marked.
WHEELS COASTS AFTER BEING TURNED OFF.
NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal
sparking of the motor could ignite fumes.
DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an
authorized service center.

GENERAL SAFETY RULES
INSPECT TOOL CORDS PERIODICALLY. If damaged,
have repaired by a qualified service technician at an
authorized service facility. The conductor with insulation
having an outer surface that is green 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. Repair or replace a damaged
or worn cord immediately. Stay constantly aware of cord
location and keep it well away from the rotating grinding
wheels.
INSPECT EXTENSION CORDS PERIODICALLY and
replace if damaged.
USE ONLY CORRECT WHEELS. DO NOT use wheels
with incorrect size holes. Never use wheel washers or
wheel bolts that are defective or incorrect. The maximum
wheel capacity of your grinder is 6 in.
NEVER TOUCH WHEEL or other moving parts during
use.
NEVER START A TOOL WHEN ANY ROTATiNG
COMPONENT IS IN CONTACT WITH THE WORKPIECE.

EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding
plugs and 3-pole receptacles that accept the product’s plug.
When using a power tool at a considerable distance from
the power source, use an extension cord heavy enough to
carry the current that the product will draw. An undersized
extension cord will cause a drop in line voltage, resulting in
a loss of power and causing the motor to overheat. Use the
chart provided below to determine the minimum wire size
required in an extension cord. Only round jacketed cords
listed by Underwriter’s Laboratories (UL) should be used.
**Ampere rating (on product data plate)

**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
When working with the product outdoors, use an extension
cord that is designed for outside use. This is indicated by
the letters “W-A” or “W” on the cord’s jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on lumber,
tools, or other obstructions while you are working with a
power tool. Failure to do so can result in serious personal
injury.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use the product with a
damaged cord since touching the damaged area could
cause electrical shock resulting in serious injury.
ELECTRICAL CONNECTION
This product is powered by a precision-built electric motor.
It should be connected to a power supply that is 120 V, AC
only (normal household current), 60 Hz. Do not operate this
product on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If
the product does not operate when plugged into an outlet,
double check the power supply.
SPEED AND WIRING
The no-load speed of this product is approximately 3,600
rpm. This speed is not constant and decreases under a load
or with lower voltage. For voltage, the wiring in a shop is as
important as the motor’s horsepower rating. A line intended
only for lights cannot properly carry a power tool motor. Wire
that is heavy enough for a short distance will be too light for
a greater distance. A line that can support one power tool
may not be able to support two or three products.
GROUNDING INSTRUCTIONS
See Figure 1, page 11.
This product must be grounded. In the event of a malfunction
or breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock.
This product is equipped with an electric cord having an
equipment-grounding conductor and 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.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
WARNING:
Improper connection of the grounding plug can result in a
risk of electric shock. When repair or replacement of the
cord is required, do not connect the grounding wire to
either flat blade terminal. The wire with insulation having
an outer surface that is green with or without yellow
stripes is the grounding wire.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the product is properly grounded.
Repair or replace a damaged or worn cord immediately.
This product is for use on a nominal 120 V circuit and has
a grounding plug similar to the plug illustrated in figure 1,
page 11. Only connect the product to an outlet having the
same configuration as the plug. Do not use an adapter with
this product.

APPLICATIONS
This product has been designed only for the purposes listed
below:
Sharpening drill bits
Sharpening lawn mower blades
Sharpening chisels and flat screwdrivers
LED LIGHT SWITCH
See Figure 9, page 12.
Use the LED light switch on top of the spark shield assembly
to turn the lights on and off.
BASIC OPERATION
To be efficient and work as designed, your tools should be
kept sharp. Dull tools can and will cause accidents.
Bench grinders are ideal for sharpening tools such as chisels,
scissors, etc., and for removing rust or corrosion. Grinders
remove material rapidly so pressure is the key to efficient
grinding.
The proper way to sharpen a tool and avoid overheating is:
Keep the object in constant motion, moving it at an even
pace.
Never force a tool against the grinding wheel.
Keep the tool cool by using a pan of water.
The grinding wheel should rotate “into” the object being
sharpened.
NOTE: Excessive pressure may damage the tool, cause
the motor to overheat, and prematurely wear down the
grinding wheel.
ON/OFF SWITCH
See Figure 10, page 12.
The bench grinder features a front access on/off switch for
convenience and safety.
SHARPENING TWIST DRILL BITS
See Figure 11, page 13.
Drill bits are best sharpened on a sharpening jig (available at
most hardware stores). Begin on one side of the point at the
existing angle, then twist the bit while maintaining contact
with the 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.
SHARPENING LAWN MOWER BLADES
See Figure 12, page 13.
Lawn mower blades are usually sharpened on only one edge
and dressed up slightly on the other. Perform this sharpening
process on both cutting ends of the blade. After sharpening,
be sure to balance the blade by removing additional material.
NOTICE:
An unbalanced lawn mower blade may cause excessive
vibration which will damage the lawn mower.
SHARPENING CHISELS AND SCREWDRIVER
BLADES
See Figure 13, page 13.
When sharpening chisels and screwdrivers, work rest should
support the chisel at the correct angle against the wheel.
