Residual Risks; Risk Reduction; Operation - Ryobi R18BS Original Instructions Manual

RESIDUAL RISKS

Even when the product 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:
■ entrapment/contact with the moving belt
Additional caution must be exercised to prevent
operator's fingers and hands from coming into contact
with the abrasive belt or entrapped by the rollers.
■ contact with or inhalation of dust
While using the product, considerable dust and fine
particles will be produced. Use the dust collection
device or connect a dust extraction vacuum during use.
Wear respiratory protection masks containing filters
appropriate to the materials being worked. Ensure
adequate workplace ventilation. Do not eat, drink, or
smoke in the work area.
■ risk of explosion
Accumulated fine dust may ignite and cause fire. Keep
the work area clean and free from dust. Dust collection
and vacuum extraction systems should be regularly and
thoroughly cleaned. When sanding metal, hot sparks
may be produced.
■ noise and vibration
Wear ear protection when operating the product. Do not
operate the product for extended periods of time.

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.

OPERATION

■ Do not operate the product without a properly tracked
and fitted belt. An incorrectly tracked belt may come off
the product and cause personal injury or damage to the
sander.
■ Secure the workpiece with a vice or clamp to a suitable
work bench. This helps to prevent the workpiece
becoming a thrown object.
■ Use the supplied handles to hold and control the
product with both hands.
■ Do not force the product. Use the correct product for
your application. The correct product will do the job
better and safer at the rate for which it was designed.
■ Do not apply excessive pressure to the product. Let the
weight of the product apply the correct pressure and use
your hands to guide the sander. Excessive pressure will
overload the product and damage the motor. Applying
more pressure will not remove more material and will
reduce sanding efficiency instead.
■ Change the sanding belt often to maintain the product's
ability to effectively remove material.
■ Start the product using the trigger switch and allow the
belt to gain correct speed. Then lower the belt onto the
workpiece. Hold the product securely in both hands
because the movement of the belt will drive the product
forwards.
■ Choose a belt of the correct size and appropriate
roughness for the task. Use belts with a lower grit
number for removing more material; higher grit number
for removing less material and for a finer finish. Replace
the belt if it becomes damaged, clogged with debris or
is worn.
■ It is normal to sand and move the product back and
forth along the grain of the material. Sanding across the
grain will work, but produces a scratched and damaged
surface.
WARNING
Dust from certain paints, coatings, and materials may
cause irritation or allergic reactions to the respiratory
system. Dust from wood, such as oak, beech, MDF, and
others are carcinogenic. Materials containing asbestos
should only be worked or processed by qualified
specialist operators.
■ Use the dust collector or connect the dust port to a
vacuum device to reduce risks associated with dust
particles.
■ All persons within the work area or nearby should wear
dust masks which offer appropriate protection.
■ Always wear safety goggles or safety glasses with side
shields during operation.
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.
