This electric power tool must be used as a grinder and cut-off grinder. 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 sanding, for use with wire brushes or polishing. 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 recom- mend 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 dimensions of the electric power tool. Incorrectly measured insertion tools cannot be adequately shielded or controlled.

Sanding discs, 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.L 3709-115, L 3709-125, LE 9-10 125

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. 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 application. 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.

Never use insertion tools which require liquid coolants. The use of water or other liquid coolants may result in electric shock. 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. For example, if a sanding disc is snagged or pinched by the workpiece, the edge of the sanding disc which is entering the workpiece may become caught and cause the sanding disc to break off or kick back. The sanding disc then moves towards or away from the operator, depending on the direction in which the disc is rotating at the point of pinching. Sanding discs may also break under these conditions. A recoil occurs if the electric power tool is used incorrectly or improperly. A recoil can be prevented by appropriate precautions as described below.L 3709-115, L 3709-125, LE 9-10 125

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 kickback 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 grinding and cut-off grinding:

Use only those sanding tools authorised for use with your electric power tool and the guard designated for this sanding tool. Sanding tools, which are not designated for use with the electric power tool, cannot be adequately shielded and are unsafe.

The guard must be attached securely to the electric power tool and adjusted to ensure maximum safety, i.e. the smallest possible part of the sanding tool is exposed to the operator. The guard should protect the operator from fragments and accidental contact with the sanding tool.

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 cut-off grinding:

Avoid blocking the cutting-off wheel or exerting too high contact pressure. Do not make excessively deep cuts. Overloading the cutting-off wheel increases its stress and the susceptibility to twisting or blocking and therefore the possibility of a kickback or the grinding tool breaking.

Avoid the area in front of and behind the rotating cutting-off wheel. When you move the cutting-off wheel in the workpiece away from yourself, a kickback may cause the electric power tool and rotating wheel to be ejected directly towards you.

If the cutting-off wheel jams or you interrupt work, switch the power tool off and hold it steady until the wheel has come to a standstill. Never attempt to pull the still rotating cutting- off wheel out of the cut, otherwise a kickback may occur. Establish and eliminate the cause of the jam.

Do not switch the electric power tool on again while it is in the workpiece. First let the cutting-off wheel reach full speed before you carefully continue cutting. Otherwise, the wheel may jam, jump out of the workpiece or cause a kickback.

Be particularly careful when making “pocket cuts” in existing walls or other secluded areas. When the cutting-off wheel is inserted, it may cause a kickback if it cuts into gas or water lines, electric cables or other objects.L 3709-115, L 3709-125, LE 9-10 125

Support plates or large workpieces to prevent the risk of a kickback due to the cutting-off wheel jamming. Large workpieces may sag under their own weight. The workpiece must be supported on both sides of the wheel, namely near the separating cut and along the edge. Additional safety instructions The mains voltage and the voltage specifications on the rating plate (9) must correspond. Do not press the spindle lock (4) until the grinding tool stops. Noise and vibration The noise and vibration values have been determined in accordance with EN 60745. The A evaluated noise level of the power tool is typically: – Sound pressure level: 84.6 dB(A); – Sound power level: 95.6 dB(A); – Uncertainty: K = 3.0 dB. Total vibration value (when sanding surfaces): – Emission value: a

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 decrease 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. `~ìíáçå tÉ~ê=É~ê=éêçíÉÅíáçå=~í=~=ëçìåÇ=éêÉëëìêÉ= ~ÄçîÉ=UR=Ç_E^FK Operating instructions t^okfkd> Before carrying out any work on the angle grinder, always pull out the mains plug.
