■
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
tool 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.
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 whenever you use
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 any 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 fi ngers, 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.
STARTUP PROTECTION
Machines with a lock-on switch are fi tted with a cut-out.
This prevents the machine from restarting by itself after a
power failure. When resuming work, switch the machine off
and then switch it back on again.
MAINTENANCE
WARNING
Do not make any adjustments while the motor is in
motion.
The product should never be connected to a power
supply when assembling parts, making adjustments,
cleaning, performing maintenance, or when the product
is not in use. Disconnecting the product will prevent
accidental starting that could cause serious injury.
■
After use, check the product to make sure that it is in
good condition.
■
It is recommended that you take the product to a RYOBI
