General Safety Warnings
WARNING: For your own safety, read the instruction manual for
both the grinder tool and the dust extractor vacuum before using
any accessory. Failure to heed these warnings may result in personal
injury and serious damage to the tool and the accessory. When
servicing this tool, use only identical replacement parts.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
b) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
c) Ensure the workplace is well ventilated. Exposure to dust
at a poorly ventilated workplace may result in damage to the
health.
2) ELECTRICAL SAFETY
a) Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is earthed or
grounded.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a
power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while
operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
d) Dress properly. Do not wear loose clothing or jewelry.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair can be caught in
moving parts.

4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the job
better and safer at the rate for which it was designed.
WARNING: The use of any accessory or attachment or
performance of any operation with this tool, other than those
recommended in this instruction manual may present a risk of
personal injury.
b) Store idle power tools out of the reach of children and do
not allow persons unfamiliar with the power tool or these
instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
c) Use the power tool, accessories and tool bits etc., in
accordance with these instructions taking into account
the working conditions and the work to be performed.
Use of the power tool for operations different from those
intended could result in a hazardous situation.
5) SERVICE
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
Tuckpointing Safety Rules
• Do not use accessories which are not specifically designed
and recommended by the tool manufacturer. Just because
the accessory can be attached to your power tool, it does not
assure safe operation.
• The rated speed of the accessory must be at least equal to
the maximum speed marked on the power tool. Accessories
running faster than their rated speed can break and fly apart.
• The outside diameter and the thickness of your accessory
must be within the capacity rating of your power tool.
Incorrectly sized accessories cannot be adequately guarded or
controlled.
• The arbor size of wheels, flanges, backing pads or any other
accessory must properly fit the spindle of the power tool.
Accessories with arbor holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
• The guard must be securely attached to the power tool
and positioned for maximum safety, so the least amount
of wheel is exposed towards the operator. The guard helps
to protect operator from broken wheel fragments and accidental
contact with wheel.
• Hold power tool by insulated gripping surfaces only, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of the
power tool "live" and shock the operator.
• Always use side handle. Tighten the handle securely. The
side handle should always be used to maintain control of the tool
at all times.
• Do not use a damaged accessory. Before each use inspect
the accessory such as diamond wheel for chips and cracks,
backing pad for cracks, tear or excess wear, wire brush
for loose or cracked wires. If power tool or accessory is
dropped, inspect for damage or install an undamaged
accessory. After inspecting and installing an accessory,
position yourself and bystanders away from the plane of
the rotating accessory and run the power tool at maximum
no-load speed for one minute. Damaged accessories will
normally break apart during this test time.

• DO NOT grind or cut metal with a diamond wheel.
• Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping small abrasive or
workpiece fragments. The eye protection must be capable of
stopping flying debris generated by various operations. The dust
mask or respirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high intensity noise may
cause hearing loss.
• Do not "jam" the cut-off wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and susceptibility
to twisting or binding of the wheel in the cut and the possibility of
kickback or wheel breakage.
• Position the cord clear of the spinning accessory. If you lose
control, the cord may be cut or snagged and your hand or arm may
be pulled into the spinning accessory.
• Never lay the power tool down until the accessory has come
to a complete stop. The spinning accessory may grab the surface
and pull the power tool out of your control.
• Do not run the power tool while carrying it at your side.
Accidental contact with the spinning accessory could snag your
clothing, pulling the accessory into your body.
• Regularly clean the power tool’s air vents. The motor’s fan will
draw the dust inside the housing and excessive accumulation of
powdered metal may cause electrical hazards.
• Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
• Do not use accessories that require liquid coolants. Using
water or other liquid coolants may result in electrocution or shock.
• DO NOT use abrasive wheels.
• ALWAYS use with a dust collector.
WARNING: When not in use, place grinder on a stable surface
where it will not move inadvertantly, roll or cause a tripping or
falling hazard. Serious personal injury may result.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are
NOT safety glasses. Also use face or dust mask if cutting operation is
dusty. ALWAYS wear certified safety equipment:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3).
• ANSI S12.6 (S3.19) hearing protection.
• NIOSH/OSHA respiratory protection.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities 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 and cement and other masonry
products, and
• 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 filter out
microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on
the skin may promote absorption of harmful chemicals.
