Safety guidelines during power tool operation
• Before any repair and replacement work to the machine,
the power plug must be pulled out firstly.
• Notice the power voltage: in power connection, you
must confirm that if the power voltage is the same
to the voltage marked in the tool's data plate. If the
power voltage is higher than the appropriate voltage,
the accidents will be resulted to the operators, and at
the same time, the tool will be destroyed. Therefore, if
the power voltage has not been confirmed, then you
shall never plug in arbitrarily. On the contrary, when
the power voltage is lower than the required voltage,
the motor will be damaged.
Safety warnings common for grinding, sanding, wire
brushing and polishing:
• ST62 brush sander is a high-performance equipment
intended to polish, sand or grind different surfaces and
materials by coupling different wheels. 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.
• 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, it does not assure safe operation.
• 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.
• The outside diameter and the thickness of your acces-
sory must be within the capacity rating of your power
tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
• The arbour size of wheels, flanges, backing pads or
any other accessory must properly fit the spindle of the
power tool. Accessories with arbour holes that do not
match the mounting hardware of the power tool will
run out of balance, vibrate excessively and may cause
loss of control.
• 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.
• Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety glas-
ses. As appropriate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stopping small
10
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 filtratin particles generated by your
operation. Prolonged exposure to high intensity noise
may cause hearing loss.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• Do not operate the power tool near flammable ma-
terials. Sparks could ignite these materials.
• Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-trolled
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 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.
