DIE GRINDER SAFETY WARNINGS
Safety Warnings Common for Grinding Operation:
1.
This power tool is intended to function as a grinder.
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 sanding, wire brushing, polish
-
ing or cutting-off are not recommended to be per
-
formed 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 manufac
-
turer.
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 controlled.
6.
The arbour size of accessories must properly
fit the 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.
7.
Mandrel mounted 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 accessory may
become loose and be ejected at high velocity.
8.
Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels
for chips and cracks. If power tool or accessory is
dropped, inspect for damage or install an undam
-
aged 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.
9.
Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro
-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop
-
ping 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.
10.
Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear per
-
sonal protective equipment.
Fragments of workpiece
or of a broken accessory may fly away and cause injury
beyond immediate area of operation.
11.
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 electric shock.
12.
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.
13.
Use clamps to support workpiece whenever practi
-
cal. 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.
14.
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.
15.
Never lay the power tool down until the acces
-
sory has come to a complete stop.
The spinning
accessory may grab the surface and pull the
power tool out of your control.
16.
After changing the bits or making any adjust
-
ments, make sure the collet nut, chuck or any
other adjustment devices are securely tight
-
ened.
Loose adjustment devices can unexpect
-
edly shift, causing loss of control, loose rotating
components will be violently thrown.
17.
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.
18.
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.
19.
Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
20.
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 rotat
-
ing 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 acces
-
sory’s rotation.
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.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a)
Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces.
The operator can control
kickback forces, if proper precautions are taken.
