Combined safety instructions for grinding, sanding and polishing

This electric power tool must be used as a grinder, sander and polisher. Observe all safety information, instructions, diagrams and data which you receive with the power tool. If you do not observe the following instructions, an electric shock, fire and/or serious injuries may occur.

■ This electric power tool is not suitable for use with wire brushes and for cut-off grinding. If the electric power tool is not used as intended, the user may be exposed to hazards and may be injured.

■ Never use accessories which the manufacturer did not intend or recommend especially for this electric power tool. Just because you can attach the accessory to your electric power tool does not guarantee safe use.

■ The permitted speed of the insertion tool must be at least as high as the maximum speed indicated on the electric power tool. An accessory which rotates faster than permitted may shatter and fly off.

■ Outer diameter and thickness of the insertion tool must correspond to the dimen-sions of the electric power tool. Incorrectly measured insertion tools cannot be adequately shielded or controlled.

■ Grinding discs, flanges, sanding pads or other accessories must fit exactly on the grinding spindle of your electric power tool. Insertion tools, which do not fit exactly on the grinding spindle of the electric power tool, rotate unevenly, vibrate violently and may result in loss of control.

■ Do not use any damaged insertion tools. Before use, always check insertion tools for splinters and cracks, sanding pad for cracks, wear and severe abrasion, wire brushes for loose or broken wires. If the electric power tool or the insertion tool is dropped, check for damage or use an undamaged insertion tool. When you have checked and inserted the tool, ensure that you and anybody in the vicinity remain outside the plane of the rotating insertion tool and leave the power tool running for one minute at maximum speed. Damaged insertion tools usually break during this test time.

■ Wear personal protective equipment. Depending on the application, wear full face protection, eye protection or goggles. If appropriate, wear a dust mask, hearing protection, protective gloves and/or a special apron which protect you from small sanding and material particles. You should protect your eyes from foreign objects which are ejected for different applications. Dust and respirator masks must filter the dust which is generated by the power tool for the particular appli-cation. If you are exposed to loud noise for a prolonged period, you may suffer hearing loss.

■ Ensure that other persons are situated at a safe distance from the work area. Anyone who enters the work area must wear personal protective equipment. Fragments of the workpiece or broken insertion tools may fly off and cause injuries even outside the direct working area.

If the insertion tool is at risk of coming into contact with concealed power cables or the power cord itself, hold the power tool by the insulated grip surfaces only. Contact with a live cable may also cause metal parts of the appliance to become live and result in an electric shock.

- Keep the power cord away from rotating insertion tools. If you lose control of the appliance, the power cord could be severed or become caught and your hand or arm may strike the rotating insertion tool.

■ Never put down the electric power tool until the insertion tool has come to a standstill. The rotating insertion tool may come into contact with the support surface, possibly resulting in you losing control of the electric power tool.
■ Never leave the electric power tool running while you are carrying it.

Your clothing may become caught by accidental contact with the rotating insertion tool which may then drill into your body.

■ Regularly clean the ventilation slots on your electric power tool.

The motor fan draws dust into the housing; a large build-up of metal dust may cause electrical hazards.

■ Never use the electric power tool near combustible materials.

Sparks may ignite these materials.

Recoil and appropriate safety instructions

Kickback is the sudden reaction to a pinched or snagged rotating insertion tool, such as a sanding disc, sanding pad, wire brush, etc. Pinching or snagging may cause a rotating insertion tool to stop abruptly. As a result, an uncontrolled electric power tool is accelerated against the direction of rotation of the insertion tool at the blocking point.

■ Hold the electric power tool firmly and position your body and arms to allow you to absorb kickback forces. If fitted, always use the auxiliary handle to ensure the best possible control over the recoil forces or reaction torques when acceleration occurs. The operator can control kickback and reaction forces by taking appropriate precautions.
- Keep your hands away from the rotating insertion tool. The insertion tool may kick-back over your hand.
- Keep your body out of the area into which the electric power tool moves when a recoil occurs. Kickback propels the electric power tool in the direction opposite to the movement of the sanding disc at the point of pinching.

■ Work especially carefully near corners, sharp edges, etc. Prevent the insertion tool from recoiling off the workpiece and jamming. The rotating insertion tool has a tendency to snag on corners, sharp edges or if it bounces. This causes a loss of control or kickback.
■ Do not use a chain or toothed saw blade. Such insertion tools frequently cause a kickback or the loss of control of the electric power tool.

Special safety instructions for sanding

■ Use only those grinding tools which are permitted for your electric power tool. Sanding tools, which are not designated for use with the electric power tool, cannot be adequately shielded and are unsafe.
■ Sanding tools may be used for the recommended applications only. For example: Never grind with the side area of a cutting-off wheel. Cutting-off wheels are designed to remove material with the edge of the wheel. If a lateral force is applied to these sanding tools, they may shatter.
■ Always use undamaged clamping flanges in the correct size and shape for the grinding disc you have selected. Suitable flanges support the grinding disc and therefore reduce the risk of the grinding disc breaking. Flanges for cutting-off wheels may differ from the flanges for other grinding discs.
■ Do not use worn grinding discs from larger electric power tools. Grinding discs for larger electric power tools are not designed for the higher speeds of smaller electric power tools and may break.

Special safety instructions for sanding

- Do not use oversized sanding sheets, but follow the manufacturer's specifications for the size of sanding sheets. Sanding sheets which project over the sanding pad may cause injuries as well as block and rip the sanding sheets or cause a kickback.

Special safety instructions for polishing

■ Do not allow any loose parts of the polishing hood, in particular fixing cords. Stow or shorten the fixing cords. Loose, entrained fixing cords may trap your fingers or become entangled in the workpiece.

Noise and Vibration

The noise and vibration values have been determined in accordance with EN 62841. The A evaluated noise level of the power tool is typically:

	Sound pressure level [dB(A)]	Sound power level [dB(A)]	Uncertainty K [dB]
LW 1202 N/~SN	92 100 3

Total vibration value (3-axis) when grinding natural stone with corundum grinding rings (LW 1202 N/\~SN):

	a_h [m/s2]		Uncertainty K [m/s2]
	Grinding rings K60	Diamond wheel K400, wet
LW 1202 N/~SN 3	.0 – 1.5

CAUTION!

The indicated measurements refer to new power tools. Daily use causes the noise and vibration values to change.

NOTE

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period For a precise estimation of the vibration load the times should also be considered during which the power tool is switched off or even running, but not actually in use.

This may significantly increase the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

CAUTION!

Wear ear protection at a sound pressure above 85 dB(A).
