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
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.
■ 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.
■ Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
■ 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.
■ 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.
■ 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
OPERATIONS
Safety warnings speci fi c for grinding operations:
■ 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.
■ 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.
■ 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.
■ 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.
■ 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.
■ 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.
ANGLE GRINDER SAFETY PRECAUTIONS
■ Check that the speed marked on the grinding wheel is
equal to or greater than the rated speed of the product.
■ Ensure that the dimensions of the grinding wheel are
compatible with the product and that the wheel fits the
spindle.
■ Grinding wheels must be stored in a dry place.
■ Do not store objects on top of the grinding wheels.
■ Grinding wheels must not be used for any operation
other than grinding.
■ Grinding wheels must be stored and handled with care
in accordance with the manufacturer’s instruction.
■ 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.
■ Ensure that the wheel is fitted in accordance with this
manual.
■ 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. Stop
immediately if there is considerable vibration or if other
defects are detected. If this condition occurs, check the
product to determine the cause.
■ Do not use separate reducing bushings or adapters to
adapt large hole grinding wheels.
■ Check that the workpiece is properly supported.
■ Use only grinding wheels approved by RYOBI.
■ Ensure that sparks resulting from use do not create
a hazard, e.g., do not hit people, or ignite flammable
substances.
■ Always use protective safety glasses and ear protectors.
■ Use other personal protective equipment, such as
gloves, apron, and helmet, when necessary.
■ 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.
■ Use the product only for approved applications. Never
use coolants or water or use the tool as a fixed tool.
■ Grip the product securely with both hands while
operating.
ADDITIONAL SAFETY WARNINGS
■ We recommend the use of a residual current device
with a residual current rating of 30 mA or less.
ANGLE GRINDER SAFETY PRECAUTIONS
■ Check that the speed marked on the grinding wheel is
equal to or greater than the rated speed of the product.
■ Ensure that the dimensions of the grinding wheel are
compatible with the product and that the wheel fits the
spindle.
