Safety Warnings Common For Grinding Or Abrasive Cutting-Off Operations; Kickback And Related Warnings - Hitachi G 12SE2 Handling Instructions Manual

5) Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.
SAFETY WARNINGS COMMON FOR
GRINDING OR ABRASIVE CUTTING-OFF
OPERATIONS
a) This power tool is intended to function as a
grinder 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.
b) Operations such as sanding, wire brushing or
polishing are not recommended to be performed
with this power tool.
Operations for which the power tool was not
designed may create a hazard and cause personal
injury.
c) 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.
d) 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.
e) 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.
f) The arbour size of wheels, flanges, backing pads
or any other accessory must properly fit the
spindle of the power tool.
Accessories with arbour 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.
g) 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.
h) 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.
i) 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 accessory
may fly away and cause injury beyond immediate
area of operation.
j) Hold the 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 could give the operator an electric shock.
k) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled
into the spinning accessory.
l) 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.
m) 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.
n) 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.
o) Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
p) 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 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.
