c. 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.

d. 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.

e. The arbour size of wheels, flanges, backing pads or

any other accessory must properly fit the spindle of
the power tool.

Accessories with arbour holes that do not

match the mounting hardware of the power tool will run
out of balance, vibrate excessively and may cause loss of
control.

f. Do not use a damaged accessory. Before each use

inspect the accessory such as abrasive wheels for chips
and cracks, backing pad for cracks, tear or excess wear,
wire brush for loose or cracked wires. If power tool or
accessory is dropped, inspect for damage or install an
undamaged accessory. After inspecting and installing
anaccessory, 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.

g. 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.

h. 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.

i. 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 shock the
operator.

j. 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.

k. 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.

l. 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.

m. 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.

n. Do not operate the power tool near flammable materials.

Sparks could ignite these materials.

o. 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 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.

e. Do not attach a saw chain woodcarving blade or toothed

saw blade.

Such blades create frequent kickback and loss

of control.

SAFETY WARNINGS SPECIFIC FOR GRINDING

AND ABRASIVE CUTTING-OFF OPERATIONS

a. Use only wheel types that are recommended for your

power tool and the specific guard designed for the
selected wheel.

Wheels for which the power tool was not

designed cannot be adequately guarded and are unsafe.

b. Wheels must be used only for recommended

applications. For example: do not grind with the side
of cut-off wheel.

Abrasive cut-off wheels are intended for

peripheral grinding, side forces applied to these wheels may
cause them to shatter.

c. Always use undamaged wheel flanges that are of

correct size and shape for your selected wheel.

Proper

wheel flanges support the wheel thus reducing the possibility
of wheel breakage. Flanges for cut-off wheels may be
different from grinding wheel flanges.

d. Do not use worn down wheels from larger power tools.

Wheel intended for larger power tool is not suitable for the
higher speed of a smaller tool and may burst.

ADDITIONAL SAFETY WARNINGS SPECIFIC

FOR ABRASIVE CUTTING OFF OPERATIONS

a. Do not "jam" the cut-off wheel or apply excessive

pressure. Do not attempt to make an excessive depth
of cut.

Overstressing the wheel increases the loading and

susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.

b. Do not position your body in line with and behind the

rotating wheel.

When the wheel, at the point of operation,

is moving away from your body, the possible kickback may
propel the spinning wheel and the power tool directly at you.

c. When wheel is binding or when interrupting a cut for

any reason, switch off the power tool and hold the
power tool motionless until the wheel comes to a
complete stop. Never attempt to remove the cut-
off wheel from the cut while the wheel is in motion
otherwise kickback may occur.

Investigate and take

corrective action to eliminate the cause of wheel binding.

d. Do not restart the cutting operation in the workpiece.

Let the wheel reach full speed and carefully reenter the
cut.

The wheel may bind, walk up or kickback if the power

tool is restarted in the workpiece.

e. Support panels or any oversized workpiece to minimize

the risk of wheel pinching and kickback.

Large

workpieces tend to sag under their own weight. Supports
must be placed under the workpiece near the line of cut and
near the edge of the workpiece on both sides of the wheel.

f. Use extra caution when making a "pocket cut" into

existing walls or other blind areas.

The protruding wheel

may cut gas or water pipes, electrical wiring or objects that
can cause kickback.

SAFETY WARNINGS SPECIFIC FOR

SANDING OPERATIONS

a. Do not use excessively oversized sanding disc paper.

Follow manufacturers recommendations, 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.
