WOLFF BS 180 Traduction Du Mode D'emploi Original page 13

Do not use defective or incomplete guard.
g) Use only grinding media approved for your
guard.
Grinding media for which the guard was not designed
cannot be adequately guarded and are unsafe.
h) Treaded mounting of accessories must match the
grinder spindle thread.
i)For accessories mounted by flanges, the arbour hole
of the accessory must fit the locating diameter of the
flange.
Accessories that do not match themounting hardware of
the power tool will run out of balance, vibrate excessively
and may cause loss of control.
j) 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.
k) Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of
stopping small abrasive or workpiece fragments.
The eye protectionmust be capable of stopping flying
debris generated by various operations.
The dust mask or respirator must be capable of filtrating
particles generated by your operation. Prolonged
exposure to high intensity noise
may cause hearing loss.
l) Keep bystanders a safe distance away from work
area.Anyone entering the work areamust wear
personal protective equipment.
Fragments of workpiece or of a broken accessory may fly
away and cause injury beyond immediate area of
operation.
m) Hold 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 shock the
operator.
n) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged and
your hand or armmay be pulled into the spinning
accessory.
o) 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.
p) 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.
q) Regularly clean the power tool's air vents.
Themotor's fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
r) Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
s) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
4.2 Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled 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.
a) 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.
