WARNING

Read all safety warnings and all instructions. Failure to follow the

warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

Do not use this power tool before you have thoroughly read and completely understood this Instruction Manual and the enclosed "General

Safety Instructions" (document number 341 30 465 06 0). The documents mentioned should be kept for later use and enclosed with the power tool, should it be passed on or sold.

Please also observe the relevant national industrial safety regulations.

Intended use of the power tool:

hand-guided bevel milling machine for professional use by instructed operating personnel in weather-protected environments using the application tools and accessories recommended by FEIN:

• for machining workpieces made of steel, cast steel, fine-grained steel, stainless steel, aluminium, aluminium alloys, brass and plastic
• for commercial use in industry and trade
  for the preparation of K-, V-, X- and Y-shaped welding joints

• for machining visible edges in plant, equipment and general engineering

• for rounding edges for optimal paint preparation or as impact protection

This power tool is also suitable for use with AC generators with sufficient power output that correspond to the Standard ISO 8528, design type G2. This Standard is particularly not complied with when the so-called distortion factor exceeds 10% . When in doubt, please refer to the generator instruction/specification guide.

Special safety instructions.

Hold the power tool only by the insulated gripping surfaces, as the cutting tool could cut into the machine's power cord. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and shock the operator.

Fasten and secure the workpiece with screw clamps or other suitable clamps to a stable surface. When holding the workpiece manually it is unstable and can lead to loss of control and injury.

Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.

Do not use a damaged accessory. Before each use, check the indexable inserts for chipping and cracks, wear or heavy use. If the machine or application tool is dropped, inspect for damage or install an undamaged application tool.

Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. Where appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.

Always hold the power tool firmly when starting it. The reaction torque of the motor, as it accelerates to full speed, can cause the power tool to twist.

If possible, use clamps to fasten or affix the workpiece. Never hold a workpiece in one hand and the power tool in the other hand while in use. Clamping workpieces allows you to use both hands for better control the power tool.

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.

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.

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.

Do not operate the power tool near flammable materials. Sparks could ignite these materials.

Do not use accessories that require liquid coolants.

Using water or other liquid coolants may result in electrocution or shock.

Secure the work piece firmly. A work piece that is gripped tightly in a clamping device or vice, is more secure than if held by hand.

Before putting into operation, check the mains connection and the mains plug for damage.

Recommendation: The tool should always be supplied with power via a residual current device (RCD) with a rated current of 30mA or less.

Kickback and related warnings

Kickback is the sudden reaction to a pinched or snagged rotating application tool. Pinching or snagging causes the rotating application tool to rapidly stop. This can cause a power tool to be forced in the opposite direction to the rotating application tool at the point of binding.

For example, if the indexable insert is snagged or pinched in the workpiece, the edge of the indexable insert entering into the workpiece can get caught, causing the indexable insert to break out or cause kickback. The indexable-insert holder may either jump toward or away from the operator, depending on the direction of the indexable-insert holder at the point of binding. Indexable inserts can also break under these conditions. Kickback is the result of power tool misuse or incorrect operating procedures. It can be avoided by taking proper precautions as described below.

Maintain a firm grip on the power tool and position your body and arms to allow you to resist kickback forces. The operator can control torque reactions or kickback forces, if proper precautions are taken.

Use special care when working corners, sharp edges, etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.

Always feed the application tool into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the chips are thrown). Guiding the power tool in the wrong direction causes the cutting edge of the application tool to climb out of the workpiece and pull the tool in the direction of this feed.

Do not jam or seize the indexable insert or apply excessive pressure. Do not set a larger bevel height than the maximum allowed. Overstressing the indexable inserts increases the loading and susceptibility to wedging or snagging in the cut, and thus increases the possibility of kickback or indexable insert breakage.

Do not position your body directly in front or behind the indexable insert when operating the machine, position yourself parallel to the cutting surface. When moving the indexable inserts into the workpiece any potential kickback could result in contact with the indexable inserts.

Turn or replace blunt indexable inserts or those with worn off coating in good time. Blunt indexable inserts increase the risk of the machine jamming and breaking out.

Do not use the power tool without the guide plate.

Further safety warnings

Use ear protection during operation.

Indexable inserts, indexable-insert holder, workpiece and chippings can be hot after working. Wear protective gloves.

Use only sharp, undamaged indexable inserts.

Keep your hands away from the milling area and the application tools.

Do not direct the power tool against yourself, other persons or animals. Danger of injury from sharp or hot application tools.

Use a stationary extraction system, blow out ventilation slots frequently and connect a residual current device (RCD) on the line side. When working metal under extreme operating conditions, it is possible for conductive dust to settle in the interior of the power tool. The total insulation of the power tool can be impaired.

Do not rivet or screw any name-plates or signs onto the power tool. If the insulation is damaged, protection against an electric shock will be ineffective.

Do not work with materials containing magnesium.

Danger of fire.

Do not work with CFRP (carbon-fiber-reinforced polymer) and materials containing asbestos. These materials are considered carcinogenic.

Replace a damaged or cracked auxiliary handle. Do not operate the power tool with a defective auxiliary handle.

Hand/arm vibrations

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.

An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce 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.

Handling hazardous dusts

For work procedures with this power tool where material is removed, dusts develop that can be hazardous to one's health.

Contact with or inhaling some dust types, e. g. asbestos and asbestos-containing materials, lead-containing coatings, metal, some wood types, minerals, silicate particles from materials containing stone, paint solvents, wood preservatives, antifouling paints for vessels, can trigger allergic reactions to the operator or bystanders and/or lead to respiratory infections, cancer, birth defects or other reproductive harm. The risk from inhaling dusts depends on the exposition. Use dust extraction matched appropriately for the developing dust, as well as personal protective equipment and provide for good ventilation of the workplace. Leave the processing of asbestos-containing materials to specialists.

Wood and light-metal dust, hot mixtures of grinding dust and chemical materials can self-ignite under unfavourable conditions or cause an explosion. Avoid sparking in the direction of the dust collector as well as overheating of the power tool and the materials being sanded, empty the dust collector/container in time, observe the material manufacturer's working instructions, as well as the relevant regulations in your country for the materials being worked.

Operating Instructions.

Guide the power tool toward the workpiece only when switched on. Otherwise, the workpiece and application tools may be damaged.

During machining, the guide roller must always be in contact with the workpiece.

0 Firstly remove the switched-on power tool from the workpiece and then switch it off. Otherwise, the workpiece and application tools may be damaged.
If power tool vibrations increase significantly, check the setting parameters for the respective application material and the condition of the application tool.

WARNING

Danger of injury from chippings.

Always keep your hands, clothing

etc. away from chippings. Do not attempt to remove the application tool when still rotating. This can lead to serious injuries.

WARNING

Danger of injury from sharp edges

of the milling head. Do not touch

the sharp edges of the milling head.

WARNING

Danger of burning. The application

tool can become hot during opera

tion. Allow the application tool to cool down:

• after placing the power tool down

• prior to tool changing.

Rotate or turn around the eightfold heads as required. Please note that milling head, guide rollers and indexable inserts may vary depending on the application. Only use accessories approved for the application.

When machining bevels and radii, pay attention that the correct speed stage is set dependent of the material.

Various materials can be subject to hardening at the edges due to heating, plasma or laser cutting. This can lead to very high deviations from the specified reference values.

Setting the bevel height (see page 9/10)

Use indexable inserts for bevels, which are available as accessories. Set the bevel height "a" via the setting dimension at the guide plate. Make a test run. As the scale has a tolerance of approx. ± 1mm (approx. 1 / 32^ ), readjustment may be necessary. Readjustment is made using the second scale (numbers 1 to 15) on the guide plate. The guide plate is adjusted by 0.1mm (1 / 254^ ) per digit. The maximum, material-dependent setting dimension and the recommended speed stage can be found in the following two tables.

Setting the radius dimension (see page 10)

Use indexable inserts for radii, which are available as accessories. The setting dimension of the guide plate must be adapted to the respective radius. For setting dimension values, please refer to the respective accessory. For the material-dependent speed stage, please refer to the two tables below.
