Cut-Off Machine Safety Warnings; Kickback And Related Warnings - Bosch GCO 14-24 J Professional Notice Originale

Keep cutting tools sharp and clean. Properly main-
u
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in
u
accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
Keep handles and grasping surfaces dry, clean and
u
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.

Cut-off machine safety warnings

Position yourself and bystanders away from the plane
u
of the rotating wheel. The guard helps to protect the op-
erator from broken wheel fragments and accidental con-
tact with wheel.
Use only bonded reinforced cut-off wheels for your
u
power tool. Just because an accessory can be attached
to your power tool, it does not assure safe operation.
The rated speed of the accessory must be at least
u
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed
can break and fly apart.
Wheels must be used only for recommended applica-
u
tions. For example: do not grind with the side of a cut-
off wheel. Abrasive cut-off wheels are intended for peri-
pheral grinding, side forces applied to these wheels may
cause them to shatter.
Always use undamaged wheel flanges that are of cor-
u
rect diameter for your selected wheel. Proper wheel
flanges support the wheel thus reducing the possibility of
wheel breakage.
The outside diameter and the thickness of your ac-
u
cessory must be within the capacity rating of your
power tool. Incorrectly sized accessories cannot be ad-
equately guarded or controlled.
The arbour size of wheels and flanges must properly
u
fit the spindle of the power tool. Wheels and flanges
with arbour holes that do not match the mounting hard-
ware of the power tool will run out of balance, vibrate ex-
cessively and may cause loss of control.
Do not use damaged wheels. Before each use, inspect
u
the wheels for chips and cracks. If the power tool or
wheel is dropped, inspect for damage or install an un-
damaged wheel. After inspecting and installing the
wheel, position yourself and bystanders away from
the plane of the rotating wheel and run the power tool
at maximum no load speed for one minute. Damaged
wheels will normally break apart during this test time.

Wear personal protective equipment. Depending on
u
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and shop apron capable of stopping
small abrasive or workpiece fragments. The eye pro-
tection must be capable of stopping flying debris gener-
ated 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.
Keep bystanders a safe distance away from work area.
u
Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a
broken wheel may fly away and cause injury beyond im-
mediate area of operation.
Position the cord clear of the spinning accessory. If
u
you lose control, the cord may be cut or snagged and your
hand or arm may be pulled into the spinning wheel.
Regularly clean the power tool's air vents. The motor's
u
fan can draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
Do not operate the power tool near flammable materi-
u
als. Do not operate the power tool while placed on a
combustible surface such as wood. Sparks could ignite
these materials.
Do not use accessories that require liquid coolants.
u
Using water or other liquid coolants may result in electro-
cution or shock.

Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged rotat-
ing wheel. Pinching or snagging causes rapid stalling of the
rotating wheel which in turn causes the uncontrolled cutting
unit to be forced upwards toward the operator.
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. 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
u
your body and arm to allow you to resist kickback
forces. The operator can control upward kickback forces,
if proper precautions are taken.
Do not position your body in line with the rotating
u
wheel. If kickback occurs, it will propel the cutting unit
upwards toward the operator.
Do not attach a saw chain, woodcarving blade, seg-
u
mented diamond wheel with a peripheral gap greater
than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
Do not "jam" the wheel or apply excessive pressure.
u
Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and sus-
