1. Machine-specific SafetyWarnings
1.1. Safety Warnings Common for Grinding,
Sanding, Wire Brushing or Abrasive Cutting-Off
Operations
This power tool is intended to function as a grinder,
sander, wire brush or cut-off tool. 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.
This power tool is not recommended for polishing.
Operations for which the power tool was not designed may
create a hazard and cause personal 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
accessory must be within the capacity rating of your
power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
The arbor size of wheels, flanges, backing pads or any
other accessory must properly fit the spindle of the
power tool. Accessories with arbor 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 pads for cracks, tears or excess wear,
wire brushes 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 your self 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
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stopping
small 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 filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause
hearing loss.
Keep bystanders a safe distance away from the work
ENGLISH

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 only by the insulated gripping
surfaces when performing an operation where the
cutting accessory may contact hidden wiring or its own
cord. Contact with a "live" wire will also make exposed
metal parts of the power tool "live" and shock the operator.
Position the cord clear of the spinning accessory. If you
lose control of the power tool, 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
materials. 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.
1.2. 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.
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.
Never place your hand near the rotating accessory. The
accessory may kickback over your hand.
Do not position your body in the area where the power
