7. Do not use a damaged accessory. Before each
use inspect the accessory such as backing
pad for cracks, tear or excess wear. 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.
8. 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.
9. 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.
10. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden
wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
Never lay the power tool down until the acces-
11.
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
12. 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.
13. 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.
14. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
15. 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 wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled power tool to be forced in the direction opposite
of the accessory's rotation at the point of the binding.
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.
Maintain a firm grip on the power tool and
1.
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or kick-
back forces, if proper precautions are taken.
2. Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
3. Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite
to the wheel's movement at the point of snagging.
4. 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.
5. Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specific for Sanding Operations:
1. Do not use excessively oversized sanding
disc paper. Follow manufacturers recommen-
dations, when selecting sanding paper. Larger
sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Safety Warnings Specific for Polishing Operations:
1. Do not allow any loose portion of the polish-
ing bonnet or its attachment strings to spin
freely. Tuck away or trim any loose attach-
ment strings. Loose and spinning attachment
strings can entangle your fingers or snag on the
workpiece.
Additional Safety Warnings:
Make sure the wheel is not contacting the
1.
workpiece before the switch is turned on.
2. 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.
3. Use the specified surface of the wheel to per-
form the sanding or polishing.
4. Do not leave the tool running. Operate the tool
only when hand-held.
