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 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
11.
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.
b) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
c) Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.
d) Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direction
as the chips are thrown). Feeding the tool in the
wrong direction causes the cutting edge of the
bit to climb out of the work and pull the tool in the
direction of this feed.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended
for your power tool and only for recommended
applications.
b) Do not position your hand in line with and
behind the rotating wheel. When the wheel, at
the point of operation, is moving away from your
hand, the possible kickback may propel the spin-
ning wheel and the power tool directly at you.
Additional Safety Warnings:
21. The tool is intended for use with bonded abra-
sive wheel points (grinding stones) perma-
nently mounted on plain, unthreaded mandrel
(shanks).
22. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
23. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
24. Use the specified surface of the wheel to per-
form the grinding.
25. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other per-
sons or flammable materials.
26. Do not leave the tool running. Operate the tool
only when hand-held.
27. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
