Additional Safety Warnings for Angle Grinders
Safety instructions for all operations
Safety Warnings Common for Grinding 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 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 shock the operator.
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.
