DIE GRINDER SAFETY WARNINGS
Safety Warnings Common for Grinding Operation:
This power tool is intended to function as a grinder.
1.
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 sanding, wire brushing, polish-
2.
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.
Do not use accessories which are not specifically
3.
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.
The arbour size of accessories must properly
6.
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 undamaged accessory. After inspect-
ing and installing an accessory, position your-
self 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 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 expo-
sure 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 personal 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
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.
14. Position the cord clear of the spinning acces-
sory. 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
rotating 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 accessory'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 move-
ment 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.
