GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings and all instructions. Failure
to follow the warnings and instructions may result in
electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool’’ in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
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) Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your finger on the switch or energising power tools
that have the switch on invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
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.
b) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) 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.
e) Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.

2
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) 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.
SERVICE
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.
ANGLE GRINDER SAFETY WARNINGS
SAFETY WARNINGS COMMON FOR GRINDING OR
ABRASIVE CUTTING-OFF OPERATIONS:
a) This power tool is intended to function as a
grinder or cut-off tool. Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to follow
all instructions listed below may result in electric
shock, fire and/or serious injury.
b) Operations such as sanding, wire brushing
or polishing are not recommended to be
performed with this power tool. Operations for
which the power tool was not designed may create
a hazard and cause personal injury.
c) 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 does not assure
safe operation.
d) 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.
e) 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.
f) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the
accessory must fit the locating diameter of
the flange. Accessories that to do not match the
mounting hardware of the power tool will run out of
balance, vibrate excessively and may cause loss
of control.
g) Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels 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.
h) 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.
i) Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Fragments
of workpiece or of a broken accessory may fly
away and cause injury beyond immediate area of
operation.
j) Hold the 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 could give the
operator an electric shock.
k) 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.
l) 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.
m) 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.
n) 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.
o) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
ADDITIONAL SAFETY WARNINGS
■We recommend that the product always be supplied via
a residual current device (RCD) with a rated residual
current of 30 mA or less.
FURTHER SAFETY INSTRUCTIONS FOR ALL
OPERATIONS
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating
accessory, which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the accessory’s
rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched
by the workpiece, the edge of the wheel that is entering
into the pinch point can dig into the surface of the material
causing the wheel to climb out or kick out. The wheel may
either jump toward or away from the operator, depending
on the direction of the wheel’s movement at the point of

3
pinching. Abrasive wheels may also break under these
conditions.
Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control
over kickback or torque reaction during start-
up. The operator can control torque reactions or
kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite
to the wheel’s movement at the point of snagging.
d) Use special care when working corners, sharp
edges, etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create
frequent kickback and loss of control.
ADDITIONAL SAFETY INSTRUCTIONS FOR GRINDING
AND CUTTING-OFF OPERATIONS
Safety warnings specific for grinding and abrasive
cutting-off operations:
a) Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
b) The grinding surface of centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot
be adequately protected.
c) 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
the operator from broken wheel fragments,
accidental contact with wheel and sparks that
could ignite clothing.
d) Wheels must be used only for recommended
applications. For example: Do not grind with
the side of cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
e) Always use undamaged wheel flanges that are
of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel,
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel flanges.
f) Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool
is not suitable for the higher speed of a smaller tool
and may burst.
ADDITIONAL SAFETY WARNINGS SPECIFIC FOR
ABRASIVE CUTTING-OFF OPERATIONS
a) 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.
b) Do not position your body in line with and
behind the rotating wheel. When the wheel,
at the point of operation, is moving away from
your body, the possible kickback may propel the
spinning wheel and the power tool directly at you.
c) When wheel is binding or when interrupting a
cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never attempt
to remove the cut-off wheel from the cut while
the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted
in the workpiece.
e) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the wheel.
f) Use extra caution when making a “pocket
cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.
ANGLE GRINDER SAFETY PRECAUTIONS
a) Check that the speed marked on the grinding
wheel is equal to or greater than the rated speed
of the product.
b) Ensure that the dimensions of the grinding wheel
are compatible with the product and that the wheel
fits the spindle.
c) Grinding wheels must be stored in a dry place.
d) Do not store objects on top of the grinding wheels.
e) Grinding wheels must not be used for any operation
other than grinding.
f) Grinding wheels must be stored and handled
with care in accordance with the manufacturer’s
instruction.
g) Inspect the grinding wheel before use to ensure
that it is not chipped or cracked. Chips or cracks
can cause the wheels to shatter, resulting in
possible serious injury.
h) Ensure that the wheel is fitted in accordance with
this manual.
i) Ensure that the grinding wheel is correctly mounted
and tightened before use and run the product at
no-load speed for 30 seconds in a safe position.

or if other defects are detected. If this condition
occurs, check the tool to determine the cause.

4
j) Do not use separate reducing bushings or adapters
to adapt large hole grinding wheels.
k) Check that the workpiece is properly supported.
l) Use only grinding wheels approved by RYOBI.
m) Ensure that sparks resulting from use do not
create a hazard, e.g., do not hit people, or ignite
flammable substances.
n) Always use protective safety glasses and ear
protectors.
o) Use other personal protective equipment, such as
gloves, apron, and helmet, when necessary.
p) Never place the product on the floor or other
surfaces while it is running. Grinding wheels
continue to rotate after the product is switched off.
Never touch the wheel or place it on the floor or
other surfaces while it is rotating.
q) Use the product only for approved applications.
Never use coolants or water or use the tool as a
fixed tool.
r) Grip the product securely with both hands while
operating.
RESIDUAL RISKS
Even when the angle grinder is used as prescribed, it is
still impossible to completely eliminate certain residual risk
factors. The following hazards may arise and the operator
should pay special attention to avoid the following:
■Injury caused by thrown-off particles
–Metal or abrasive particles may enter the eyes and
cause severe permanent damage. Wear goggles
approved for grinding operations when operating
the product.
■Injury caused by vibration
–Limit exposure. See Risk Reduction.
■Injury caused by dust
–Wear appropriate dust control mask with filters
suitable for protecting against particles from the
material being worked on and abrasive particles
from the grinding disc. Do not eat, drink, or smoke
in the work area. Ensure adequate ventilation.
■Injury from contact with the grinding disc
–The disc and workpiece will become hot during
use. Wear gloves when changing discs or touching
workpiece. Keep hands away from the grinding
area at all times. Clamp the workpiece whenever
possible.
■Injury caused by noise
–Prolonged exposure to noise will increase the risk
of hearing damage, and the effects are cumulative.
When using power tools for an extended period of
time, wear hearing protection.
RISK REDUCTION
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices
are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
■Keep your body warm in cold weather. When operating
the product, wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
■After each period of operation, exercise to increase
blood circulation.
■Take frequent work breaks. Limit the amount of
exposure per day.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor about
these symptoms.
WARNING
Injuries may be caused or aggravated by prolonged use
of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
