Safety Warnings Common For Grinders, Sanding, Wire
Brushing, Polishing or Abrasive Cutting-Off Operations:
a) 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.
b) Operation such as polishing is 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) Threaded mounting of accessories must match the grinder
spindle thread. For accessories 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.
g) Do not use a damaged accessory. Before each use inspect the
accessory such as abrasive wheel 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 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 electrical 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.
