sander, wire brush, polisher or cut-off tool. 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, fi re and/or serious injury.

b) Do not use accessories which are not specifically

designed and recommended by the tool

manufacturer. Just because the accessory can be

attached to your power tool, it does not assure safe

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

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

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

inspect the accessory such as abrasive wheels for

chips and cracks, backing pads for cracks, tear or

excess wear, wire brushes for loose or cracked

wires. If the 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.

g) Wear personal protective equipment 4. Depending

on application, use face shield, safety goggles or

safety glasses. As appropriate, wear dust mask,

hearing protectors, gloves and shop apron capable

of stopping small abrasive or workpiece fragments.

The eye protection must be capable of stopping fl ying

debris generated by various operations. The dust mask

or respirator must be capable of fi ltrating 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 the

workpiece or of a broken accessory may fl y away and

cause injury beyond the immediate area of operation.

i) Hold the power tool only by the insulated gripping

surfaces when performing an operation where the

cutting tool may contact hidden wiring or its own

power cord. Contact with a “live” wire will also make

exposed metal parts of the power tool “live” and shock

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

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

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

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.7

o) Do not use accessories that require liquid coolants.

Using water or other liquid coolants may result in

electrocution or shock.

2) 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

• 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 the 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

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

b) Never place your hand near the rotating accessory.

The 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 the 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.

3) SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE CUTTING OFF OPERATIONS

a) Always use the guard designed for the type of wheel

you are using. The guard must be securely attached

to the power tool and positioned for maximum

safety, so the least amount of wheel is exposed

towards the operator. The guard helps to protect the

operator from broken wheel fragments and accidental

contact with the wheel.

b) 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

c) Wheels must be used only for recommended

applications. For example: Do not grind with the side

of a cut-off wheel. Abrasive cut-off wheels are intended

for peripheral grinding; side forces applied to these

wheels may cause them to shatter.

d) Always use undamaged wheel flanges that are of

correct size and shape for your selected wheel.

Proper wheel fl anges support the wheel thus reducing

the possibility of wheel breakage. Flanges for cut-off

wheels may be different from grinding wheel fl anges.

e) Do not use worn down wheels from larger power

tools. A wheel intended for a larger power tool is not

suitable for the higher speed of a smaller tool and may

4) 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

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 the 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

d) Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed and

carefully re-enter the cut. The wheel may bind, walk

up or kickback if the power tool is restarted in the

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

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.8

5) SAFETY WARNINGS SPECIFIC FOR SANDING OPERATIONS

a) When sanding, do not use excessively oversized

sanding disc paper. Follow the 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.

6) SAFETY WARNINGS SPECIFIC FOR POLISHING

a) Do not allow any loose portion of the polishing

bonnet or its attachment strings to spin freely.

Tuck away or trim any loose attachment strings.

Loose and spinning attachment strings can entangle

your fi ngers or snag on the workpiece.

7) SAFETY WARNINGS SPECIFIC FOR WIRE BRUSHING OPERATIONS

a) Be aware that wire bristles are thrown by the brush

even during ordinary operation. Do not overstress

the wires by applying excessive load to the brush.

The wire bristles can easily penetrate light clothing and/

b) If the use of a guard is recommended for wire

brushing, do not allow any interference of the wire

wheel or brush with the guard. Wire wheel or brush

may expand in diameter due to work load and
