GRINDER SAFETY WARNINGS
Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive Cutting-Off Operations:
1. 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.
2. Operations such as 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
16. Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may
