GENERAL SAFETY
Operating a Bench Grinder can be
dangerous if safety and common sense are
ignored. The operator must be familiar with
the operation of the tool. Read this manual
to understand this Bench Grinder. DO NOT
operate this Bench Grinder if you do not fully
understand the limitations of this tool. DO
NOT modify this Bench Grinder in any way.
4. AVOID A DANGEROUS WORKING
ENVIRONMENT. DO NOT use electrical tools
in a damp environment or expose them to
rain.
5. DO NOT use electrical tools in the
presence of ammable liquids or gasses.
6. ALWAYS keep the work area clean, well lit,
and organized. DO NOT work in an
environment with oor surfaces that are
slippery from debris, grease, and wax.
BEFORE USING GRINDER
To avoid serious injury and damage to the
tool, read and follow all of the Safety and
Operating Instructions before operating the
Bench Grinder.
1. Some dust created by using power tools
contains chemicals known to the State of
California to cause cancer, birth defects, or
other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement,
and other masonry products.
• Arsenic and chromium from
chemically treated lumber.
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to these
chemicals: work in a well ventilated area
and work with approved safety equipment,
such as those dust masks that are specially
designed to lter out microscopic particles.
2. READ the entire Owner’s Manual. LEARN
how to use the tool for its intended
applications.
3. GROUND ALL TOOLS. If the tool is
supplied with a 3-prong plug, it must be
plugged into a 3-contact electrical receptacle.
The 3rd prong is used to ground the tool and
provide protection against accidental electric
shock. DO NOT remove the 3rd prong. See
Grounding Instructions on page 7.
7. KEEP VISITORS AND CHILDREN AWAY.
DO NOT permit people to be in the
immediate work area, especially when the
electrical tool is operating.
8. DO NOT FORCE THE TOOL to perform
an operation for which it was not designed. It
will do a safer and higher quality job by only
performing operations for which the tool was
intended.
9. WEAR PROPER CLOTHING. DO NOT
wear loose clothing, gloves, neckties, or
jewelry. These items can get caught in the
machine during operations and pull the
operator into the moving parts. The user must
wear a protective cover on their hair, if the
hair is long, to prevent it from contacting any
moving parts.
10. CHILDPROOF THE WORKSHOP AREA
by removing switch keys, unplugging tools
from the electrical receptacles, and using
padlocks.
11. ALWAYS UNPLUG THE TOOL FROM
THE ELECTRICAL RECEPTACLE when
making adjustments, changing parts or
performing any maintenance.
12. KEEP PROTECTIVE GUARDS IN
PLACE AND IN WORKING ORDER.
13. AVOID ACCIDENTAL STARTING. Make
sure that the power switch is in the “OFF”
position before plugging in the power cord to
the electrical receptacle.

SAFETY INSTRUCTIONS
14. REMOVE ALL MAINTENANCE TOOLS
from the immediate area prior to turning “ON”
the Bench Grinder.
15. USE ONLY RECOMMENDED
ACCESSORIES. Use of incorrect or improper
accessories could cause serious injury to
the operator and cause damage to the tool.
If in doubt, check the instruction manual that
comes with that particular accessory.
16. NEVER LEAVE A RUNNING TOOL
UNATTENDED. Turn the power switch to the
“OFF” position. DO NOT leave the tool until it
has come to a complete stop.
17. DO NOT STAND ON A TOOL. Serious
injury could result if the tool tips over, or you
accidentally contact the tool.
18. DO NOT store anything above or near the
tool where anyone might try to stand on the
tool to reach it.
19. MAINTAIN YOUR BALANCE. DO NOT
extend yourself over the tool. Wear oil
resistant rubber soled shoes. Keep oor clear
of debris, grease, and wax.
20. MAINTAIN TOOLS WITH CARE. Always
keep tools clean and in good working order.
Keep all blades and tool bits sharp, dress
grinding wheels and change other abrasive
accessories when worn.
21. EACH AND EVERY TIME, CHECK FOR
DAMAGED PARTS PRIOR TO USING THE
TOOL. Carefully check all guards to see that
they operate properly, are not damaged, and
perform their intended functions. Check for
alignment, binding or breaking of moving
parts. A guard or other part that is damaged
should be immediately repaired or replaced.
22. DO NOT OPERATE TOOL WHILE
TIRED, OR UNDER THE INFLUENCE OF
DRUGS, MEDICATION OR ALCOHOL.
24. STAY ALERT, WATCH WHAT YOU
ARE DOING, AND USE COMMON SENSE
WHEN OPERATING A POWER TOOL.
A moment of inattention while operating
power tools may result in serious personal
injury.
25. ALWAYS WEAR A DUST MASK TO
PREVENT INHALING DANGEROUS DUST
OR AIRBORNE PARTICLES, including wood
dust, crystalline silica dust and asbestos dust.
Direct particles away from face and body.
Always operate tool in well ventilated area
and provide for proper dust removal. Use
dust collection system wherever possible.
Exposure to the dust may cause serious and
permanent respiratory or other injury,
including silicosis (a serious lung disease),
cancer, and death. Avoid breathing the dust,
and avoid prolonged contact with dust.
Allowing dust to get into your mouth or eyes,
or lay on your skin may promote absorption of
harmful material. Always use properly tting
NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure,
and wash exposed areas with soap and water.
26. USE A PROPER EXTENSION CORD IN
GOOD CONDITION. When using an
extension cord, be sure to use one heavy
enough to carry the current your product will
draw. The table on page 8 shows the correct
size to use depending on cord length and
nameplate amperage rating. If in doubt, use
the next heavier gauge. The smaller the
gauge number, the larger diameter of the
extension cord. If in doubt of the proper size of
an extension cord, use a shorter and thicker
cord. An undersized cord will cause a
drop in line voltage resulting in a loss of power
and overheating. USE ONLY A 3-WIRE
EXTENSION CORD THAT HAS A 3-PRONG
GROUNDING PLUG AND A 3-POLE
RECEPTACLE THATACCEPTS THE TOOL’S
PLUG.
23. SECURE ALL WORK. Use clamps or
jigs to secure the workpiece. This is safer than
attempting to hold the workpiece with your
hands.

SPECIFIC SAFETY
INSTRUCTIONS FOR BENCH
GRINDERS
The operation of any grinder or power tool
can result in debris being thrown into your
eyes, which can result in severe and permanent eye damage. ALWAYS WEAR EYE
PROTECTION. Everyday eyeglasse are NOT
safety glasses. ALWAYS wear Safety Goggles
(that comply with ANSI standard Z87.1) when
operating power tools.
Basic precautions should always be followed
when using your bench grinder. To reduce the
risk of injury, electrical shock, or re, comply
with the safety rules listed below:
1. ALWAYS USE THE EYESHIELDS AND
WHEEL GUARDS provided with the grinder.
2. REPLACE A CRACKED OR DAMAGED
GRINDING WHEEL IMMEDIATELY. A
damaged wheel can discharge debris at a
high velocity towards the operator. Carefully
handle the grinding wheels since they are
abrasive. Prior to replacing a grinding wheel,
check it for cracks. DO NOT remove the
blotter or label on both sides of the grinding
wheel. Tighten the spindle nut just enough to
hold the grinding wheel rmly to the Bench
Grinder. DO NOT over-tighten the nut.
Excessive clamping force can damage the
grinding wheel. Only use the wheel anges
provided with the grinder. When selecting a
replacement grinding wheel use only properly
sized wheels, and verify that the grinding
wheel has a higher R.P.M. rating than the
maximum R.P.M. of the Bench Grinder.
3. THE DIAMETER OF THE GRINDING
WHEELS WILL DECREASE WITH USE.
Adjust the tool rests and spark arrestors to
maintain a distance of 1/16” from the wheel.
4. DO NOT STAND IN FRONT OF THE
BENCH GRINDER WHEN STARTING IT.
Stand to one side of the Bench Grinder and
turn it “ON”. Wait at the side for one minute
until the grinder comes up to full speed. There
is always a possibility that debris from a
damaged grinding wheel may be discharged
towards the operator.
5. THE BENCH GRINDER WILL PRODUCE
SPARKS AND DEBRIS DURING GRINDING
OPERATIONS. Be sure that there are not any
ammable materials in the vicinity. Frequently
clean grinding dust from the back of the
Bench Grinder.
6. NEVER FORCE THE WORKPIECE
AGAINST A GRINDING WHEEL, especially
if the wheel is cold. Apply the workpiece
slowly, allowing the grinding wheel an
opportunity to warm up. This will minimize
the chance of wheel breakage. DO NOT grind
using the sides of the grinding wheels. DO
NOT apply coolant directly to the grinding
wheel.
7. KEEP ALL WHEEL GUARDS IN PLACE.
DO NOT USE THE BENCH GRINDER WITH
THE WHEEL GUARDS REMOVED.
8. KEEP THE TOOL RESTS FIRMLY IN
PLACE AND TIGHTENED. Use them to
safely position your material for grinding.
9. ALWAYS USE THE SUPPLIED WHEEL
DRESSER TO RESURFACE THE FACE OF
THE GRINDING WHEEL.
10. DRESS THE GRINDING WHEEL
OFTEN. This will keep the wheel surface at
and free of nicks and residue/glaze.
11. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are
removed from grinder before turning it on.
12. ALLOW THE GRINDER TO ATTAIN
FULL SPEED BEFORE BEGINNING WORK.
13. NEVER STOP THE GRINDER BY
FORCING MATERIAL INTO THE WHEEL.
Let the grinder stop rotating on its own.
14. SECURE THE BENCH GRINDER to a
stand or workbench to prevent sliding or
tipping during use. See page 12.
15. FREQUENTLY clean grinding dust from
inside of the wheel guards and beneath
grinder.
16. NEVER GRIND SMALL STOCK without
it being properly supported on the tool rests,
and held by pliers or clamps.
