SAFETY INSTRUCTIONS

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.

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.

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.

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.

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.

23. SECURE ALL WORK. Use clamps or
jigs to secure the work piece. This is safer
than attempting to hold the work piece with

your hands.

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 THAT
ACCEPTS THE TOOL’S PLUG.

SAFETY INSTRUCTIONS

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 eyeglasses 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 EYE SHIELDS 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 WORK PIECE

AGAINST A GRINDING WHEEL, especially
if the wheel is cold. Apply the work piece
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 guards and beneath the grinder.

16. NEVER GRIND SMALL STOCK without

it being properly supported on the tool rests,

and held by pliers or clamps.
