English

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.

p ) Do not use Type 11 (flaring cup) wheels on this

tool. Using inappropriate accessories can result

ininjury.

q ) Always use side handle. Tighten the handle

securely. The side handle should always be used to

maintain control of the tool at alltimes.

r ) When starting the tool with a new or

replacement wheel, or a new or replacement

wire brush installed, hold the tool in a well

protected area and let it run for one minute. If

the wheel has an undetected crack or flaw, it

should burst in less than one minute. If the wire

brush has loose wires, they will be detected.

Never start the tool with a person in line with the

wheel. This includes theoperator.

s ) Use of accessories not specified in this manual

is not recommended and may be hazardous.

Use of power boosters that would cause the tool

to be driven at speeds greater than its rated speed

constitutesmisuse.

t ) Use clamps or another practical way to secure

and support the workpiece to a stable platform.

Holding the work by hand or against your body leaves

it unstable and may lead to loss ofcontrol.

u ) Avoid bouncing the wheel or giving it rough

treatment. If this occurs, stop the tool and inspect the

wheel for cracks orflaws.

v ) Always handle and store wheels in a carefulmanner.

w ) Do not operate this tool for long periods of time.

Vibration caused by the operating action of this

tool may cause permanent injury to fingers,

hands, and arms. Use gloves to provide extra

cushion, take frequent rest periods, and limit daily

time ofuse.

x ) Air vents often cover moving parts and should be

avoided. Loose clothes, jewelry or long hair can be

caught in movingparts.

Causes and Operator Prevention

of Kickback

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 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 reaction 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 ) The grinding surface of center depressed wheels

must not be mounted below the plane of the

guard lip. An improperly mounted wheel that

projects through the plane of the guard lip cannot be

adequatelyprotected.

c ) 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, accidental contact with

wheel and sparks that could igniteclothing.

d ) 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.

e ) 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.
