SPECIAL SAFETY RULES FOR
BENCH GRINDERS
WARNING:
Do not operate your bench grinder until it
is assembled, and you have read and understand the following
instructions and the warning labels on the bench grinder.
Before Operating Your Bench Grinder
Check for proper assembly and proper alignment of
moving parts.
Understand the function and proper use of:
●
Eye shields
●
Tool rests
Read, understand and follow all operating instructions
and safety warnings in this manual.
Read and understand warning labels on the bench
grinder.
Know the condition of your bench grinder. If any part
is missing, bent or does not operate properly, replace
the component before you continue to use your
bench grinder.
Determine the type of work you are going to be doing
before you operate your bench grinder. Properly
protect your body including your eyes, hands,
face and ears.
Only wear safety goggles that comply with
ANSI Z87.1
● The operation of any
grinder can result in foreign
objects being thrown into
your eyes, which can result
in severe eye damage.
● Glasses or goggles that are
not in compliance with ANSI
Z87.1 could break resulting in severe eye injury.
Wear a face or dust mask when working in a dusty
environment.
●
Use ear protection, plugs or muffs, during extended
periods of operation.
Always use tool guards and eye shields provided
with the grinder, safety goggles or other eye
protection. Keep your thumbs and fingers away from
the wheel.
Replace a cracked grinding wheel immediately.
A cracked wheel can throw pieces at a high velocity.
Handle wheels carefully; before replacing a wheel,
check it for cracks. Tighten the spindle nut just enough
to hold the wheel firmly: if the nut is tightened too
much, the clamping strain can damage the wheel.
Use only wheel flanges provided with grinder. When
selecting a replacement wheel, be sure that the grinder
will not exceed the manufacturer's recommended
speed (RPMs) for the wheel.
The diameter of the grinding wheel decreases
with use. Adjust tool rests to maintain a distance of
1/16" or less from the wheel. Also keep the distance
between the spark arrestor and grinding wheel 1/8"
or less.
Do not stand in front of the grinder when starting
it. There is always a possibility that a piece from a
damaged grinding wheel may be thrown off when
coming to full speed. To start the grinder, stand to
one side and turn it on. Wait at side until the grinder
comes up to full speed.
The exhaust chute will channel out sparks and
debris. Be sure the exhaust is not in the vicinity of
flammable material. Frequently clean grinding dust
from the back of the grinder.
Never force work against a grinding wheel. If the
wheel is cold. Apply the work gradually to give the
wheel an opportunity to warm. This will minimize the
chance of wheel breakage.

wheel.
ELECTRICAL REQUIREMENTS
WARNING:
• Use only manufacturer’s recommended replacement parts, or
equivalent, when servicing this tool.
• Do not touch the metal blades on the power cord plug when
removing or installing the plug into an electrical outlet.
• To avoid electrical hazards, fire hazards, or damage to the
tool, use proper circuit protection.
Your bench grinder is wired at the factory for 120V
operation. Connect to a 120V, 15 AMP time delayed
fuse or circuit breaker. To avoid shock or fire, replace
power cord immediately if it is worn, cut or damaged in
any way.
Use a separate electrical circuit for your tools.
This circuit must not be less than a #12 wire and
should be protected with a 15 Amp time delayed fuse.
Before connecting the motor to the power line, make
sure the switch is in the OFF position and the electric
current is rated the same as the current stamped on
the motor nameplate. Running at a lower voltage will
damage the motor.
When operating a power tool outside, use an
outdoor extension cord marked "W-A" or "W". These
cords are rated for outdoor use and reduce the risk of
electric shock.
WARNING:
This bench grinder is for indoor use only.
Do not expose to rain or use in damp location. This tool must be
grounded while in use to protect the operator from electrical
shock.
Do not modify the power cord plug. If it does not
match the electrical outlet, have the proper outlet
installed by a qualified electrician.
SAVE THESE SAFETY INSTRUCTIONS
Page 6
Guidelines for Extension Cords
Use proper extension cord. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one 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 cause overheating. The table below
shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Be sure your extension cord is properly wired and
in good operating condition. Always replace a
damaged extension cord or have it repaired by a
qualified person before using it.
Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
In the event of a malfunction or breakdown,
grounding provides the path of least resistance for
electric current and reduces the risk of electric shock.
This tool is equipped with an electric cord that has an
equipment grounding conductor and a grounding plug.
The plug MUST be plugged into a matching
receptacle 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
receptacle, have the proper receptacle installed by
an electrician.
Improper connection of the equipment grounding
conductor can result in 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.
Check with a qualified electrician or service personnel
if you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool’s plug.
This tool is intended for use on a circuit that has a
receptacle like the one illustrated in Figure A, a
3-wire electrical plug and receptacle that has a
grounding conductor. If a properly grounded
receptacle is not available, an adapter, Figure B, can
be used to temporarily connect this plug to a
2-contact ungrounded receptacle. The adapter,
Figure B, has a rigid lug extending from it that MUST
be connected to a permanent earth ground, such as
a properly grounded receptacle box.
Repair or replace damaged or worn cord immediately.

OPERATION
A bench grinder is designed for hand grinding
operations such as sharpening chisels, screwdrivers,
drill bits, removing excess metal, and smoothing
metal surfaces.
A Medium Grain Abrasive Grinding Wheel is suitable
for rough grinding where a considerable amount of
metal must be removed or when obtaining a smooth
finish is not important.
A Fine Grain Abrasive Grinding Wheel should be
used for sharpening tools or grinding to close size
tolerances because it removes metal more gradually
for precision grinding and gives work a smooth finish.
A wire brush is suitable for removing rust, burrs, etc.
from surfaces when a smooth finish is not important.
A variety of wire brushes are available for many
applications.
LIGHT (Figure 6)
1. This light provides focused lighting on the
workpiece when the grinder is operating at normal
operating speed.
2. The 12V bulb automatically turns "ON" as the
RPMs of the motor reach normal operating speed.
3. Use only automotive, 12V, single-contact bayonet
bulbs (3) when replacing. Position the lamp (1) as
desired.
4. Rotate the shade (2) for better illumination. To
change the light bulb, see page 11.
MOUNTING THE GRINDER (Figure 7)
1. To prevent the grinder from moving during
operation, it should be securely mounted to a
work surface or grinder stand.
2. Align the mounting holes on the grinder with
predrilled holes in a bench or grinder stand.
3. Insert bolts through the holes and tighten, using
washers, and nuts (not included) as shown in Fig. 7.
CHANGING THE GRINDING WHEEL (Figure 8)

2. Check for 1/16" clearance between the wheel and
tool rests; and 1/8" clearance between the wheel
and the spark arrestors. Hand turn the grinding
wheel to check alignment and to be sure no other
part is binding the grinding wheel.
Note: Always keep the tool rests adjusted so they clear the
wheel and are located at the center line of the wheel or just
below the center line. This will help prevent accidental jamming of
work between the wheel and the tool rest.
CAUTION:
DO NOT stand in front of the grinder when
starting. Stand to one side and turn on the grinder. Let it come up
to speed and idle for one minute. There is always the possibility
that a piece from a damaged grinding wheel may be thrown off
when coming up to full speed.
WHEN GRINDING
When grinding, ALWAYS keep the workpiece moving
across the face of the wheel. Continually grinding
against the same spot on the wheel will cause grooves
to be worn into the face of the wheel. Tool rests can
be adjusted to accommodate larger, odd-shaped
work pieces.
Never grind against the side of the wheel.
RESHAPING GRINDING WHEEL
When a grinding wheel wears out-of-round it is
necessary to reshape the wheel.
ALWAYS use the dressing wheel tool (not supplied)
when reshaping.
Note: After reshaping it will be necessary to readjust the tool
rests and spark arrestors to maintain proper clearance from the
wheel.

are grinding), get dull, and lose their shape. The
dressing wheel is the one remedy for all three of
these conditions.
1. Adjust the tool rests (1) to a horizontal position.
2. Turn on the grinder, making sure to follow all
safety precautions.
3. Firmly place fingers in the recessed gripping slots
and support the dressing wheel on the tool rest,
making sure that the dressing tool (2) makes
contact with the grinding wheel at a position just
below the center point of the grinding wheel
surface.
4. Move the dressing wheel across the wheel face
to remove material and restore the wheel surface.
