ENGLISH

• Use clamps or other practical ways to secure and

support the workpiece to a stable platform. Holding

the work by hand or against your body is unstable and

may lead to loss of control and injury.

• Do not use Type 11 (flaring cup) wheels on this tool.

Using inappropriate accessories can result in injury.

• Always use auxiliary handle. Tighten the handle

securely. The auxiliary handle should always be used to

maintain control of the tool at all times.

• 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.

• To prevent the spindle end from contacting the

bottom of the hole of the hubbed wheel, use

accessories that have a threaded hole depth of

at least 21 mm. Failure to use an accessory with the

appropriate thread depth could result in damage to the

hubbed wheel and injury to the operator or persons in

the area.

• Avoid bouncing the wheel or giving it rough

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

wheel for cracks or flaws.

• Always handle and store wheels in a careful manner.

• 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.

• Safety goggles or safety glasses with side shields

and a full face shield compliant with ANSI Z87.1

MUST be worn by the operator and others that are

within 50' (15.2 m) of the use of this product.

• Air vents often cover moving parts and should

be avoided. Loose clothes, jewelry or long hair can be

caught in movingparts.

• An extension cord must have adequate wire size

(AWG or American Wire Gauge) for safety. The smaller

the gauge number of the wire, the greater the capacity

of the cable, that is, 16 gauge has more capacity than 18

gauge. An undersized cord will cause a drop in line voltage

resulting in loss of power and overheating. When using

more than one extension to make up the total length,

be sure each individual extension contains at least the

minimum wire size. The following table shows the correct

size to use depending on cord length and nameplate

ampere rating. If in doubt, use the next heavier gauge. The

lower the gauge number, the heavier thecord.
