General Power Tool Safety Warnings
WARNING
Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below 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.

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 that may ignite dust or fumes.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

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 the 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. The use of a cord suitable for outdoor 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. The use of an RCD reduces the risk of electric shock.

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 a 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 a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing 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 jewelry. Keep your hair and clothing away from moving parts.
    Loose clothes, jewelry, 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.
  • Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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 de­
  • 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 re­ move the battery pack, if detachable, from the power tool before making any adjustments, changing ac­ cessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool
  • 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
  • Maintain power tools and accessories. Check for mis­ alignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, 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
  • Use the power tool, accessories and tool bits, etc. in accordance with these instructions, taking into ac­ count the working conditions and the work to be per­ Use of the power tool for operations different from those intended could result in a hazardous situation.
  • Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Battery tool use and care

  • Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
  • Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
  • When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
  • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally oc curs, flush with water. If liquid contacts eyes, addi tionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
  • Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire,  explosion, or risk of injury.
  • Do not expose a battery pack or tool to fire or excess ive temperature. Exposure to fire or temperature above 130°C may cause an explosion.
  • Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

Noise/Vibration Information
Noise emission values determined according to
EN 62841‑2‑8.
Typically, the A-weighted sound pressure level of the power tool is less than 70 dB(A). The noise level when working can exceed the volume stated. Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 62841‑2‑8:
ah = 7 m/s² , K = 1.5 m/s².

The vibration level and noise emission value given in these instructions have been measured in accordance with a standardized measuring procedure and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period.

To estimate vibration and noise emissions accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions over the total working period.
Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organizing workflows correctly.

Assembly

Battery Charging

  • Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your power tool.

Note: The battery is supplied partially charged. To ensure full battery capacity, fully charge the battery in the charger before using your power tool for the first time.

The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging process does not damage the  battery.
The lithium-ion battery is protected against deep discharge by the “Electronic Cell Protection (ECP)”. When the battery is discharged, the power tool is switched off by means of a protective circuit: The application tool no longer rotates.

  • Do not continue to press the On/Off switch after the power tool has automatically switched off. The battery can be damaged.

Removing the battery
To remove the battery (2), press the battery release buttons (1) and pull the battery out of the power tool. Do not use force to do this.

Battery charge indicator
The three green LEDs on the battery charge indicator (4) indicate the battery’s state of charge (2). For safety reasons, it is only possible to check the state of charge when the power tool is not in operation.
To display the state of charge, press and hold the battery charge indicator button (3) when the power tool is switched off.

Working Advice

  • Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is a risk of injury from unintentionally pressing the on/off switch.
  • This power tool is not suitable for bench-mounted use. It must not be clamped into a vice or fastened to a workbench, for example.
  • Wear protective gloves during work. Make sure that cut sheet parts are not bent towards your body. Sharp burrs develop on cut sheets;  these can cause injury.

When necessary and while wearing gloves, press bending sheet parts away from your body.
Apply the machine to the workpiece only when switched on.

Guide the power tool at an angle of 80° to 90° to the surface of the sheet metal and do not tilt it to the side.
Guide the power tool evenly, pushing it gently in the cutting direction. Applying too much pressure to the power tool will significantly reduce the service life of application tools and can damage the power tool.
When cutting curves, make sure not to tilt the power tool laterally and work with a low feed rate only.

Maximum steel sheet cutting capacity
The maximum steel sheet cutting capacity Dmax depends on the strength properties of the material to be cut.
The power tool allows for the cutting of metal sheets to the following thicknesses:

Material max. strength
(N/mm2 )
Dmax
(mm)
Steel 400 1.3
600 0.8
800 0.6
Aluminum 200 2

Adjusting cutter clearance “a”

The cutter clearance (the gap between the cutters) depends on the sheet thickness Dmax to be cut.
The clearance between the cutters should be 10 % of the maximum sheet thickness (e.g. 0.1 mm cutter clearance for 1 mm sheet thickness).
For softer or more ductile materials, the clearance must be decreased; for harder or more brittle materials, it must be increased.
Loosen the fastening screw (12) for the bottom cutter. Adjust the requested cutter clearance with the set screw (11) for the bottom cutter.  The upper cutter (9) and the bottom cutter (10) may not touch each other.
Check the clearance using the setting gauge (13). Retighten the fastening screw (12) for the bottom cutter to a tightening torque of 3–4 Nm.

Temperature-Dependent Overload Protection
In normal conditions of use, the power tool cannot be overloaded. If the power tool is overloaded or the battery temperature is outside the permitted range, the stroke rate is reduced or the power tool shuts down. When the stroke rate is reduced, the power tool will not run at the full stroke rate again until the battery temperature is back within the permitted range. In the event of automatic shutdown, switch off the power tool and allow the battery to cool down before switching the tool on again.

Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to 50 °C. Do not leave the battery in your car in the summer, for example.
Occasionally clean the ventilation slots on the battery using a soft brush that is clean and dry.
A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.

Maintenance and Service

Maintenance and Cleaning

  • Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
  • To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.

Changing the cutter (see figure A)
The upper cutter (9) and the bottom cutter (10) are identical, have four cutting edges each, and can be exchanged with each other.
Turn or replace the cutters in good time. Only sharp application tools achieve good cutting capacity and make the power tool last longer.
To replace the upper cutter (9) loosen the fastening screw (8), to replace the bottom cutter (10) loosen the fasteningscrew (12).
Turn the cutter by 90° or install a new cutter. When installing the bottom cutter (10), ensure that it fits against the set screw (11).

Note: Turn the cutter only in the direction indicated in figure A and only insert a new cutter in the position shown in the figure. Cutting is not possible with an incorrectly inserted cutter.
Retighten the fastening screw (8) for the upper cutter and the fastening screw (12) for the bottom cutter with a tightening torque of 3–4 Nm.  Check the cutter clearance as described above.
The upper cutter (9) and bottom cutter (10) may not be reground.
