English

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.

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.

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.
