Safety

Warnings

Specific

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/or skin.

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

brushing, do not allow interference of the wire

wheel or brush with the guard. Wire wheel or

brush may expand in diameter due to work load

and centrifugal forces.

Additional safety warnings:

17. When using depressed centre grinding wheels,

be sure to use only fiberglass-reinforced

wheels.

18. Be careful not to damage the spindle, the

flange (especially the installing surface) or the

lock nut. Damage to these parts could result in

wheel breakage.

19. Make sure the wheel is not contacting the

workpiece before the switch is turned on.

20. Before using the tool on an actual workpiece,

let it run for a while. Watch for vibration or

wobbling that could indicate poor installation

or a poorly balanced wheel.

21. Use the specified surface of the wheel to

perform the grinding.

22. Watch out for flying sparks. Hold the tool so

that sparks fly away from you and other

persons or flammable materials.

23. Do not leave the tool running. Operate the tool

only when hand-held.

24. Do not touch the workpiece immediately after

operation; it may be extremely hot and could

burn your skin.

25. Always be sure that the tool is switched off

and unplugged or that the battery cartridge is

operator safety.

34. Do not use the tool on any materials

containing asbestos.

35. Do not use water or grinding lubricant.

36. Ensure that ventilation openings are kept clear

when working in dusty conditions. If it should
