Sander Safety Warnings; Risk Reduction; Residual Risks; Sandpaper Selection - Ryobi RPS100 Original Instructions Manual

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.
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.
5. SERVIcE
a. Have your power tool serviced by a qualified
repair person using only identical manufacturer's
replacement parts. This will ensure that the safety
of the power tool is maintained.

SANDER SAFETY WARNINGS

■ Always wear safety goggles and a dust mask when
sanding, especially sanding over-head.
■ The machine is not suitable for wet sanding.
■ Do not use sanding paper larger than needed. Extra
paper extending beyond the sanding pad can also
cause serious lacerations.
■ The dust collection box shall be equipped with the
tool. It should be emptied frequently. To connect dust
collection box, insert the adapter of dust box to the dust-
collection opening on the rear end of the sander.
■ It is recommended that the product be always supplied
via a residual current device with a rated residual
current of 30mA or less.
WARNING
Do not throw sanding dust into an open fire because
materials in fine particle form may be explosive.
WARNING
A suitable breathing respirator must be worn while
sanding lead paint, some woods and metal to avoid
breathing the harmful/toxic dust or air.
WARNING
Dust from certain paints, coatings, and materials may
cause irritation or allergic reactions. Dust from wood,
such as oak, beech, MDF, and others are carcinogenic.
Materials containing asbestos should only be worked on
or processed by qualified specialist operators.

RESIDUAL RISKS

Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
2
factors. The following hazards may arise and the operator
should pay special attention to avoid the following:
■ Injury caused by dust
– Using the product will produce considerable amount
of dust and fine particles. Use the dust collection
device or connect a dust extraction vacuum when
operating the product. Wear dust masks containing
filters appropriate to the materials being worked on.
Ensure adequate workplace ventilation. Do not eat,
drink, or smoke in the work area.
■ Injury caused by noise and vibration
– Wear ear protection during the sanding operation.
Do not operate the product for long periods of time.
See "Risk reduction".

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 unit 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.

SANDPAPER SELEcTION

Selecting the correct size, grit and type of sand paper is an
extremely important step in achieving a high quality sanded
finish. Aluminum oxide, silicon carbide, and other synthetic
abrasives are best for power sanding. Natural abrasives,
such as flint and garnet are too soft for economical use in
power sanding.
In general, coarse grit will remove the most material
and finer grit will produce the best finish in all sanding
operations. The condition of the surface to be sanded will
determine which grit will do the job. If the surface is rough,
start with a coarse grit and sand until the surface is uniform.
Medium grit may then be used to remove scratches left
by the coarser grit and finer grit used for finishing of the
surface. Always continue sanding with each grit until
surface is uniform.
