For UK only:
 We as manufacturer and authorized person to compile the technical file, see 4) on page 4, hereby declare under sole responsibility that this metal weld bead remove, identified by type and serial number 1) on page 4 of the Original Instructions, fulfil all relevant provisions of following UK Regulations S.I. 2016/1091, S.I. 2008/1597, S.I. 2012/3032 and Designated Standards *3) on page 4.

Specified Conditions of Use

The metal weld bead remover is intended for the milling of edges of steel, stainless steel, aluminium and aluminium alloys in the professional sector.
For processing aluminium, aluminium alloys and stainless steel, a suitable lubricant (item no.:
6.23443) must be used.
This lubricant is also recommended when processing steel as it extends the tool life and the machine glides more easily over the workpiece.
The user bears sole responsibility for any damage caused by inappropriate use.
Generally accepted accident prevention regulations and the enclosed safety information must be observed.

General Safety Information

For your own protection and for the protection of your power tool, pay attention to all parts of the text that are marked with this symbol!

WARNING – Read the operating instructions to reduce the risk of injury.

WARNING Read all safety warnings and instructions. Failure to follow all safety warnings and instructions may result in electric shock, fire and/or serious injury.

Keep all safety instructions and information for future reference.
Pass on your power tool only together with these documents.

Special Safety Instructions

a) Do not use accessories that are not specifically designed and recommended for this power tool by the manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
b) Do not use damaged power tools. Before use, check the indexable inserts for chipping, cracks or signs of severe wear and tear. If a power tool or accessory is dropped, inspect for damage or install an undamaged accessory.
c) Wear personal protective equipment. Use a face shield, safety goggles or safety goggles depending on the application. As appropriate, wear a dust mask, hearing protectors, gloves and a workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. A dust mask or respirator must be capable of filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
d) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of a workpiece or broken accessory may fly away and cause injury beyond the immediate area of operation.
e) Always hold the tool firmly in your hands during the start-up. The reaction torque of the motor as it accelerates to full speed can cause the tool to twist.
f) Use clamps to support the workpiece whenever practical. Never hold a small workpiece in one hand and the tool in the other hand while in use. Clamping a small workpiece allows you to use your hands to control the tool.
g) Never lay the power tool down until the accessory has come to a complete stop. The rotating accessory may grab the surface and pull the power tool out of your control.
h) Do not run the power tool while carrying it at your side. Accidental contact with the rotating accessory could snag your clothing, pulling the accessory into your body.
i) 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.
j) Do not operate the power tool near flammable materials. Sparks and hot chips can ignite these materials.
k) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

Kickback and related warnings

Kickback is the sudden response to an accessory pinching or jamming while rotating. Pinching or snagging causes rapid stalling of the rotating accessory. This causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding.

For example, if an indexable insert is snagged or pinched by the workpiece, the edge of the insert that is entering into the pinch point can dig into the surface of the material causing the insert to climb out or kick out. The indexable insert may either jump towards or away from the operator depending on direction of the indexable insert holder at the point of pinching. Indexable inserts may also break under these conditions.

Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions. and can be avoided by taking proper precautions as given below.

a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. The operator can control kickback forces if proper precautions are taken.
b) Use special care when working in corners, on 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.
c) Always feed the accessory 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). Feeding the power tool in the wrong direction causes the cutting edge of the accessory to move out of the workpiece and pull the tool in the direction of this feed.
d) Prevent any jamming of the indexing insert or excessive pressure. Do not set the chamfer height greater than the permitted maximum. Overstressing the indexable insert increases the loading and susceptibility to twisting or binding of the disc in the cut and the possibility of kickback or breakage of the indexable insert.
e) Do not position your hand in line with and behind the indexable insert. When the indexable insert is moving away from your body at the point of operation, the possible kickback may propel the rotating indexable insert and the power tool directly at you.
f) Turn/replace blunt indexable inserts or inserts where the coating is worn in due time. Blunt indexable inserts increase the risk of the machine getting jammed and breaking.

Additional Safety Instructions:

Hold the power tool by the insulated gripping surfaces because the milling cutter may hit its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

Keep work area clean and well lit. Cluttered or dark areas invite accidents.

WARNING – Always wear protective goggles.

Wear ear protectors.
Pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning.
Wear suitable work clothes.
Ensure that nobody gets injured by catapulted foreign bodies.
Keep persons nearby and pets at a safe distance to the device.
Keep away hair, loose clothing, fingers and other body parts. They can get caught and sucked in. Use a hair net for long hair.
Warning of rotating tools

Always wear protective goggles, gloves and sturdy shoes when working with this tool.
Danger of injury from sharp edges. Wear protective gloves.

Indexable inserts, holders for indexable inserts, the workpiece and chips can be hot after work. Wear protective gloves.

A damaged or cracked additional handle must be replaced. Never operate the machine with a defective side handle.

Pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning.

Use of a fixed extractor system is recommended.
Always install an RCD with a maximum trip current of 30 mA upstream. When the machine is shut down by the RCD, it must be checked and cleaned. See chapter 10. Cleaning.

Wear ear protectors when working for long periods of time. High noise levels over a prolonged period of time may affect your hearing.
Use only sharp, undamaged indexable blades.
The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be sufficiently supported.
Ensure that sparks produced during work do not constitute a risk to the user or others and are not able to ignite flammable substances. Areas at risk must be protected with flame-resistant covers.
Always keep a fire extinguisher on hand when working in areas prone to fire risk.
Always hold the machine with both hands on the designated handles, take a secure stance and concentrate on the work.
Keep your hands away from the milling area and from the tool.
Do not touch the rotating accessory! Remove chips and similar material only with the machine at a standstill. Pull the mains plug out of the socket.
Damaged, eccentric or vibrating tools must not be used.
Do not work overhead.

Never use an incomplete tool or one on which an unauthorised modification has been made.

Reducing dust exposure:

WARNING – Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a wellventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

This also applies to dust from other materials, such as some timber types (like oak or beech dust), metals, asbestos. Other known diseases are e.g. allergic reactions, respiratory diseases. Do not let dust enter the body.

Observe the relevant guidelines and national regulations for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).

Collect the particles generated at the source, avoid deposits in the surrounding area.

Use suitable accessories for special work. In this way, fewer particles enter the environment in an uncontrolled manner.

Use a suitable extraction unit.

Reduce dust exposure with the following measures:

• do not direct the escaping particles and the exhaust air stream towards yourself or nearby persons or towards dust deposits,
• use an extraction unit and/or an air purifier,
• ensure good ventilation of the workplace and keep it clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
• Vacuum or wash protective clothing. Do not blow, beat or brush protective gear.

Setting

Pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning.
Indexable inserts, holders for indexable inserts, the workpiece and chips can be hot after work. Wear protective gloves.
Danger of crushing! Wear protective gloves.

Adjust the cutting height

Determining the setting value:

Note: always produce large seam heights in several milling operations (at least 3). Hard materials require more milling operations. This has the following advantages: a higher indexable insert service life, work results with a higher surface quality, more pleasant working conditions.
Do not exceed the stated “maximum cutting height (hmax; see Technical data) per milling operation“.

It is recommended that very little material is removed during the last milling operation to ensure an optimum surface quality.

Setting the milling heights:

1. Pull the settings ring (6) upwards and set the desired cutting height by turning in clockwise direction (+) or in anti-clockwise direction (-).
   The scale (5) is used for rough orientation during the setting process

2. setting process).

3. Carry out a trial cut.

4. Proceed as follows if the milling height should be set very accurately for the last milling operation:
   Carry out a trial cut. Measure the cut milling height and adjust it by one scale mark if necessary by turning the adjusting ring (6):
   clockwise rotation = larger milling height. Anticlockwise rotation = lower milling height. Carry out another trial cut. Repeat this step if necessary.

Use

Switching on and off

Always guide the machine with both hands.

Switch on first, then guide the accessory towards the workpiece.

Avoid inadvertent starts: always switch the tool off when the plug is removed from the mains socket or if there has been a power cut.

In continuous operation, the machine continues running if it is forced out of your hands. Therefore, always hold the machine with both hands using the handles provided, stand securely and concentrate.

Avoid the machine swirling up or taking in dust and chips. After switching off the machine, only place it down when the motor has come to a standstill.

Switching on: slide the paddle switch (17) in the direction of the arrow and then press the paddle switch (17) (see p. 3 Fig. E).
Switching off: release the paddle switch (17).

Setting speed

The speed can be preset via the thumb-wheel (13) and is infinitely variable.

Positions 1-6 correspond approximately to the following no-load speeds:

1………8000 / min 4 ……. 10800 / min
2………8900 / min 5 ……. 11700 / min
3………9900 / min 6 ……. 12600 / min

The VTC electronics make material-compatible work possible and an almost constant speed, even under load.

Speed recommendations for different materials:

Aluminium, copper, brass …………………………4-6
Steel up to 400 N/mm2……………………………..4-6
Steel up to 600 N/mm2……………………………..3-5
Steel up to 900 N/mm2……………………………..2-4
Stainless steel…………………………………………1-3

The best way to determine the ideal setting is through a practical trial

• Impacts on the indexable insert due to incorrect use: See chapter 8.3.
• Workpiece vibrations: Fix workpiece without vibrations using clamping devices.
• Indexable insert not correctly fastened: Always clean clamping surfaces and note torque.
• Indexable insert not correctly fastened: Strongly worn Indexable inserts do not have sufficient contact surfaces and therefore may not be fastened sufficiently. Replace the strongly worn indexable inserts.

Cleaning

Pull the mains plug out of the socket.
Chips and particles can deposit at the milling head (16). This can lead to blockage of the milling head.
Regularly clean the milling head and its surroundings and remove chips and particles.
Particles may become deposited inside the power tool during operation. This impairs the cooling of the power tool. Conductive build-up can impair the protective insulation of the power tool and create an electrical hazard.

The power tool should be cleaned regularly, often and thoroughly through all front and rear air vents using a vacuum cleaner. Prior to this operation, separate the power tool from the power source and wear protective goggles and a dust mask.

Troubleshooting

The electronic signal indicator (12) lights up and the load speed decreases. There is too much load on the machine! Run the machine in idling until the electronic signal indicator switches off.

The machine does not start.The electronic signal indicator (12) flashes (depending on the model). Restart protection is active. If the mains plug is inserted with the machine switched on or if the power supply is restored following an interruption, the machine does not start up. Switch the machine off and back on again.

• Restart protection: if the mains plug is inserted with the machine switched on or if the power supply is restored following an interruption, the machine does not start up. Switch the machine off and back on again.

• Overload protection: there is a reduction in load speed. The coil temperature is too high!
  Allow the machine to run at idle speed until it has cooled down.

• Switching on the machine briefly reduces the voltage. Unfavourable mains power conditions may have a detrimental effect on other machines.
  Power impedances less than 0.4 ohm should not cause malfunctions.
