DIE GRINDER SAFETY WARNINGS
SAFETY WARNINGS COMMON FOR GRINDING, SANDING,
POLISHING, CARVING OR ABRASIVE CUTTING-OFF
OPERATIONS
■
This power tool is intended to function as a grinder,
sander, polisher, carving 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.
■
Operations such as wire brushing 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.
■
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.
■
The rated speed of the grinding accessories must be
at least equal to the maximum speed marked on the
power tool.
Grinding 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 accessories cannot be
adequately controlled.
■
The arbour size of wheels, sanding drums or any
other accessory must properly fit the spindle or
collet of the power tool.
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.
■
Mandrel mounted wheels, sanding drums, cutters
or other accessories must be fully inserted into the
collet or chuck.
If the mandrel is insufficiently held and/
or the overhang of the wheel is too long, the mounted
wheel may become loose and be ejected at high velocity.
■
Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks, sanding drum 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.
■
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.
■
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.
■
Hold power tool by insulated gripping surfaces only,
when performing an operation where the cutting
accessory may contact hidden wiring.
Cutting
accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the
operator an electric shock.
■
Always hold the tool firmly in your hand(s) during
the start-up.
The reaction torque of the motor, as it
accelerates to full speed, can cause the tool to twist.
■
Use clamps to support workpiece whenever
practical.
Never hold a small workpiece in one hand
and the tool in the other hand while in use.
Clamping
a small workpiece allows you to use your hand(s) to
control the tool. Round material such as dowel rods,
pipes or tubing have a tendency to roll while being cut,
and may cause the bit to bind or jump toward you.
■
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.
■
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.
■
After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other
adjustment devices are securely tightened.
Loose
adjustment devices can unexpectedly shift, causing loss
of control, loose rotating components will be violently
thrown.
■
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.
