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 guarded or
controlled.
6.
Threaded mounting of accessories must
match the tool spindle thread. For accessories
mounted by flanges, the arbour hole of the
accessory must fit the locating diameter of the
flange.
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.
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
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.
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 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.
11.
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.
12.
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.
13.
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.
14.
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.
15.
Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other 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 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 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. Always use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or
kickback forces, if proper precautions are taken.
b)
Never place your hand near the rotating
accessory.
Accessory may kickback over your
hand.
c)
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.
d)
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.
