Safety Warnings for Concrete Grinders
Safety Warnings Common for Grinding
 This power tool is intended to function as a
grinder. 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.
 Operations such as sanding, wire brushing,
polishing or cutting-off are not recommended
to be performed with this power tool. Opera-
tions for which the power tool was not designed
may create a hazard and cause personal injury.
 Do not use accessories which are not specifi-
cally designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not as-
sure 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 ac-
cessories cannot be adequately guarded or con-
trolled.
 Threaded mounting of accessories must
match the grinder spindle thread. For acces-
sories mounted by flanges, the arbour hole of
the accessory must fit the locating diameter of
the flange. 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 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 acces-
sory 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 ro-
tating accessory and run the power tool at
16 | English
maximum no-load speed for one minute. Dam-
aged accessories will normally break apart dur-
ing this test time.
 Wear personal protective equipment. Depend-
ing on application, use face shield, safety gog-
gles or safety glasses. As appropriate, wear
dust mask, hearing protectors, gloves and
workshop apron capable of stopping small
abrasive or workpiece fragments. The eye pro-
tection must be capable of stopping flying debris
generated by various operations. The dust mask
or respirator must be capable of filtrating parti-
cles generated by your operation. Prolonged ex-
posure 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 accesso-
ry may fly away and cause injury beyond imme-
diate area of operation.
 Hold the power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed met-
al parts of the power tool "live" and could give
the operator an electric shock.
 Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled in-
to the spinning accessory.
 Never lay the power tool down until the acces-
sory has come to a complete stop. The spin-
ning 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.
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 caus-
es rapid stalling of the rotating accessory which
in turn causes the uncontrolled power tool to be
forced in the direction opposite of the acces-
sory's rotation at the point of the binding.
For example, if an abrasive wheel is snagged or
