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.
Safety warnings for angle grinder
Safety warnings common for grinding, sanding, wire
brushing or cutting-off operations:
This power tool is intended to function as a grinder,
u
sander, wire brush, hole cutter or cut-off tool. Read all
safety warnings, instructions, illustrations and spe-
cifications provided with this power tool. Failure to fol-
low all instructions listed below may result in electric
shock, fire and/or serious injury.
Operations such as polishing are not to be performed
u
with this power tool. Operations for which the power
tool was not designed may create a hazard and cause per-
sonal injury.
Do not convert this power tool to operate in a way
u
which is not specifically designed and specified by the
tool manufacturer. Such a conversion may result in a
loss of control and cause serious personal injury.
Do not use accessories which are not specifically de-
u
signed and specified 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
u
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 ac-
u
cessory must be within the capacity rating of your
power tool. Incorrectly sized accessories cannot be ad-
equately guarded or controlled.
The dimensions of the accessory mounting must fit
u
the dimensions of the mounting hardware of the
power tool. Accessories 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 in-
u
spect 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 in-
Bosch Power Tools
stall an undamaged accessory. After inspecting and
installing an accessory, position yourself and bystand-
ers 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
u
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris gen-
erated by various applications. The dust mask or respir-
ator must be capable of filtrating particles generated by
the particular application. Prolonged exposure to high in-
tensity 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 accessory may fly away and cause injury beyond
immediate area of operation.
Hold the power tool by insulated gripping surfaces
u
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 ex-
posed metal parts of the power tool "live" and could give
the operator an electric shock.
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 accessory.
Never lay the power tool down until the accessory has
u
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your con-
trol.
Do not run the power tool while carrying it at your
u
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
u
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 materi-
u
als. 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, backing pad, brush or any other accessory. Pinch-
ing or snagging causes rapid stalling of the rotating access-
ory 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
