General Power Tool Safety Warnings

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!
The term “power tool” in the warnings refers to your mains‑operated (corded) power tool or battery‑operated (cordless) power tool.

1. Work area safety
   • Keep work area clean and well lit. Cluttered or dark areas invite accidents.
   • Do  not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
   • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2. Electrical safety
   •  Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
   • Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
   • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   • Do  not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   • When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for out-door use reduces the risk of electric shock.
   • If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3. Personal safety
   • Stay alert, watch what you are doing and use common sense when operating a  power tool. Do  not use a  power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
   • Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
   • Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
   • Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
   • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   • Dress properly. Do  not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
   • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
4. Power tool use and care
   • Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
   • Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   • Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   • Store idle power tools out of the reach of children and do  not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
   • Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If dam-aged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
   • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control..
   • Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
5. Service
   • Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety instructions for stirrers

• Hold the tool with both hands at the intended handles. Loss of control can cause personal injury.
• Ensure sufficient ventilation when mixing flammable ma-terials to avoid a  hazardous atmosphere. Developing va-pour may be inhaled or be ignited by the sparks the power tool produces.
• Do not mix food. Power tools and their accessories are not designed for processing food.
• Keep the cord away from the working area. The cord may be entangled by the mixer basket.
• Ensure that the mixing container is placed in a firm and se-cure position. A container that is not properly secured may move unexpectedly.
• Ensure that no liquid splashes against the housing of the power tool. Liquid that has penetrated the power tool can cause damage and lead to electric shock.
• Follow the instructions and warnings for the material to be mixed. Material to be mixed may be harmful.
• If the power tool falls into the material to be mixed, unplug the tool immediately and have the power tool checked by a qualified repair person.
• Reaching into the bucket with the tool still plugged in can lead to electric shock.
• Do not reach into the mixing container with your hands or insert any other objects into it while mixing. Contact with the stirrer basket may lead to serious personal injury.
• Start up and run down the tool in the mixing container only. The stirrer basket may bend or spin in an uncontrolled manner.

Further safety instructions

• Check the plug and cable on a regular basis and, if they are damaged, have them replaced by an authorized customer service workshop.
• The switch must be in the OFF position before you connect it to the mains.
• Always guide the power cable from the tool to the rear. Never pull hard on the power cable and never place it on or guide it over any sharp edges.
• Only use a stirring rod with a diameter that is specified in the technical data.
• Only work in a safe and stable position.
• Do not work in damp environments.
• If moisture has penetrated the power tool, unplug the mains plug and have the power tool checked by an authorised cus-tomer service workshop.
• Do not process explosive substances (e.g. highly flammable solvents) or materials with a flash point of below 21 °C.
• Do not stir hot materials.
• Observe processing regulations provided by the manufacturer.
• Take into account that there will be a reactionary torsional momentum.
• Do not touch the connected power tool with wet hands.
• Wear suitable personal protective equipment: Ear protection, protective goggles, dust mask for work that generates dust and protective gloves when changing tools, sturdy shoes.

Other risks

Even in cases where the machine is used correctly and all relevant safety instructions have been adhered to, the design engineering of the machine and its operation mean that the following safety risks may also arise:

• Danger caused by the power cable.
• A concentration of dust which is harmful to health when working in an area that is not sufficiently ventilated.
• Injuries caused by touching electrified parts when removing the machine or its parts if the plugs on the power cable have not been removed from the socket.
• You must only use original spare parts.

Information about noise level and vibrations

The values have been measured in conformity with EN 62841. EMT 12

• Acoustic pressure level LpA = 84.5 dB (A).
• Acoustic power level LwA = 95.5 dB (A).
• In accuracy of measurements K = 1.5 dB (A).

ATTENTION! Noise is generated during work. Use ear protection!

The weighted value of vibrations affecting hands and arms ah < 2.5 m.s‑2.
In accuracy of measurements K = 1.5 m.s‑2.
The emission values specified (vibration, noise) were measured in accordance with the test conditions stipulated in EN 62841 and are intended for machine comparisons. They are also used for making preliminary estimates regarding vibration and noise loads during operation.
The emission values specified refer to the main applications for which the power tool is used. If the electric power tool is used for other applications, with other tools or is not maintained sufficiently prior to operation, however, the vibration and noise load may be higher when the tool is used.
Take into account any machine idling times and downtimes to estimate these values more accurately for a specified time period. This may significantly reduce the load during the machine operating period.

Double insulation

To ensure maximum safety of the user, our tools are designed and built to satisfy applicable European standards (EN standards). Tools with double insulation are marked by the international symbol of a double square. These tools must not be grounded and a two‑wire cable is sufficient to supply them with power. Tools are shielded in accordance with EN 55014.

Use

The power tool is designed for mixing powder construction materials such as mortar, plaster and adhesives, as well as paints and varnishes containing no solvents or similar materials.
The user bears full responsibility for the consequences of using the tool for purposes other than the above.

Commissioning

• Check that the information on the production plate matches the real voltage of the power source.
• Check that plug matches the type of socket.
• Tools designed for 230 V can also be connected to 220/240 V.

Mounting a Mixing Paddle

• Take the mixing paddle [11] with M14×2 fastening (size 22 wrench) and screw it onto the height‑adjustable adapter  [10] (size 19 wrench) by turning it to the right. Tighten it with a wrench.
• Insert the mixing paddle with firmly attached height‑adjustable adapter into the opening on the power tool’s spindle.
• For adjusting working height, see chapter Height-Adjustable Adapter.

Turning On/Off

Always hold the power tool with both hands: by the right [2] and left handle [7].
The tool is turned on and off using the switch [3] (press = on, release = off).
Speed Regulation via the Switch (Accelerating Switch)
The switch [3] also allows for the smooth adjusting of speed up to the limit set on the speed regulator.
Lock On
Pressing the switch [3] to the limit and then simultaneously pressing the lock on button [4] locks the machine in the on position. Pressing the switch [3] again and releasing it releases the lock.

Electronics

• Smooth Start-Up
  Electronic regulation ensures smooth start‑up of the power tool. Smooth start also prevents the mixed material from splashing outside the container. The low start‑up current of the power tool allows the use of 10 A fuses.

• Speed Regulation
  The speed regulator [5] allows for adjusting of the speed to: EMT 12

  1st gear| 0–360 min‑1| 4th gear| 0–520 min‑1
  2nd gear| 0–410 min‑1| 5th gear| 0–580 min‑1
  3rd gear| 0–470 min‑1| 6th gear| 0–630 min‑1

Set the speed depending on the mixing paddle and the mixed material.

• Overload Protection
  If the power tool is subjected to extreme overload, electronic safe‑ guards will protect the motor from damage. The motor will stop and will only start up again once the load has been reduced. To tool must be restarted to start working again.

• Constant Speed
  The tool’s electronics keep the speed at load nearly constant. This ensures even mixing of the material.

• Protection against Accidental Restart
  Built‑in protection against accidental restart prevents the power tool from starting up automatically after a power failure if the switch is locked in the on position. To put the tool back in operation, it has to be switched off and on again.
