hardware of the power tool will run out of balance, vibrate

excessively and may cause loss of control.

uMandrel mounted wheels, sanding drums, cutters or

other accessories must be fully inserted into the collet

or chuck. If the mandrel is insufficiently held and/or the

overhang of the wheel is too long, the mounted wheel

may become loose and be ejected at high velocity.

uDo not use a damaged accessory. Before each use in-

spect the accessory such as abrasive wheels for chips

and cracks, sanding drum for cracks, tear or excess

wear, wire brush for loose or cracked wires. If power

tool or accessory is dropped, inspect for damage or in-

stall an undamaged accessory. After inspecting and

installing an accessory, position yourself and bystand-

ers 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.

uWear personal protective equipment. Depending on

application, use face shield, safety goggles or safety

glasses. As appropriate, wear dust mask, hearing pro-

tectors, gloves and workshop apron capable of stop-

ping small abrasive or workpiece fragments. The eye

protection must be capable of stopping flying debris gen-

erated 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.

uKeep 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.

uHold power tool by insulated gripping surfaces only,

when performing an operation where the cutting ac-

cessory may contact hidden wiring or its own cord.

Cutting accessory contacting a "live" wire may make ex-

posed metal parts of the power tool "live" and could give

the operator an electric shock.

uAlways hold the tool firmly in your hand(s) during the

start-up. The reaction torque of the motor, as it acceler-

ates to full speed, can cause the tool to twist.

uUse clamps to support workpiece whenever practical.

Never hold a small workpiece in one hand and the tool

in the other hand while in use. Clamping a small work-

piece allows you to use your hand(s) to control the tool.

Round material such as dowel rods, pipes or tubing have

a tendency to roll while being cut, and may cause the bit

to bind or jump toward you.

uPosition 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.

uNever 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 con-

trol.

uAfter changing the bits or making any adjustments,

make sure the collet nut, chuck or any other adjust-

ment devices are securely tightened. Loose adjustment

devices can unexpectedly shift, causing loss of control,

loose rotating components will be violently thrown.

uDo 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.

uRegularly 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.

uDo not operate the power tool near flammable materi-

als. Sparks could ignite these materials.

uDo not use accessories that require liquid coolants.

Using water or other liquid coolants may result in electro-

cution or shock.

Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged rotat-

ing wheel, sanding band, brush or any other accessory.

Pinching or snagging causes rapid stalling of the rotating ac-

cessory which in turn causes the uncontrolled power tool to

be forced in the direction opposite of the accessory’s rota-

tion.

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 direc-

tion of the wheel’s movement at the point of pinching. Abras-

ive 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.

uMaintain a firm grip on the power tool and position

your body and arm to allow you to resist kickback

forces. The operator can control kickback forces, if

proper precautions are taken.

uUse 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.

uDo not attach a toothed saw blade. Such blades create

frequent kickback and loss of control.

uAlways feed the bit into the material in the same dir-

ection as the cutting edge is exiting from the material

(which is the same direction as the chips are thrown).

Feeding the tool in the wrong direction causes the cutting

edge of the bit to climb out of the work and pull the tool in

the direction of this feed.

uWhen using rotary files, cut-off wheels, high-speed

cutters or tungsten carbide cutters, always have the

work securely clamped. These wheels will grab if they

become slightly canted in the groove, and can kickback.
