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 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 and clothing 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 ex- traction 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 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 remove the battery pack, if detachable, 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 and accessories. Check for misalignment 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 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.
• 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 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 occurs, flush with water. If liquid contacts eyes, additionally 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 behaviour resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C may cause explosion.

Noise/Vibration Information
Noise emission values determined according to
EN 62841‑2‑8.
Typically, the A-weighted noise levels of the power tool are:
Sound pressure level 87 dB(A); sound power level 98 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 62841‑2‑8:
ah = 4.8 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 standardised 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 organising workflows correctly.

Rechargeable battery

Bosch sells some cordless power tools without a rechargeable battery. You can tell whether a rechargeable battery is included with the power tool by looking at the packaging.
Charging the battery

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

Note: Lithium-ion rechargeable batteries are supplied partially charged according to international transport regulations. To ensure full rechargeable battery capacity, fully
charge the rechargeable battery before using your tool for the first time.
Inserting the Battery
Push the charged battery into the battery holder until it clicks into place.
Removing the Battery
To remove the rechargeable battery, press the battery release button and pull the battery out. Do not use force to do this.
The rechargeable battery has two locking levels to prevent the battery from falling out if the battery release button is pressed unintentionally. The rechargeable battery is held in place by a spring when fitted in the power tool.
Battery charge indicator
The green LEDs on the battery charge indicator indicate the state of charge of the battery. For safety reasons, it is only possible to check the state of charge when the power tool is not in operation.
Press the button for the battery charge indicator  or to show the state of charge. This is also possible when the battery is removed.
If no LED lights up after pressing the button for the battery charge indicator, then the battery is defective and must be replaced.

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.

Operation

Starting Operation
Switching On and Off
To switch on the power tool, slide the on/off switch (3) forwards so that I appears on the switch.
To switch off the power tool, slide the on/off switch (3) backwards so that 0 appears on the switch.
Restart protection
The restart protection feature prevents the power tool from uncontrolled starting after the power supply to it has been interrupted.
To restart the tool, set the on/off switch (3) to the off position and then switch the power tool on again.
Soft start
The electronic soft start limits the torque when the power tool is switched on and increases the service life of the motor.
Changing the cutting direction
To change the cutting direction, the die holder (7) can be turned to three positions, each offset by 90°. Cutting towards the rear (towards the housing of the machine) is not possible.
To turn the die holder (7), loosen the die holder screw (4) until the die holder can be turned. Turn it 90° to the right or the left in relation to the longitudinal axle of the power tool. Make sure that the screw (4) engages in the drill hole of the die holder (7). Tighten the screw.
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 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. Sharp burrs develop on the cut sheets; these can cause injury.
• Exercise caution when handling the cutting chips. The chips have sharp tips that can cause injuries.

Apply the power tool to the workpiece only when switched on. Always hold the power tool vertical to the surface of the steel sheet and do not tilt it.
The cut is made as the punch moves downwards. 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.
The power tool operates more quietly when it is raised slightly during cutting. If the punch jams during cutting, switch the power tool off, lubricate the punch and release the sheet. Do not use force to do this, as this will damage the punch and the die.
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 cutting of metal sheet to the following thicknesses:

Lubricating/cooling the punch
To extend the service life of the punch (8), a lubricating agent with good cooling properties (e.g. cutting oil) should be used.
Apply a line of lubricant to the top side of the metal sheet along the intended cutting line.
Cutting along a cutting mark or with a guide
Straight cuts are carried out easier when the power tool is guided alongside a rule.
Contours can be cut by guiding the power tool along a template.
For inside cuts, a hole with a diameter of 22 mm must be pre-drilled.
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.

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.

Clean and lubricate the punch (8) and die (9) every three operating hours.
Change the punch and die in good time when worn. Only sharp tools produce a good cutting quality and make the power tool last longer.
The punch (8) and the die (9) may not be resharpened.
Changing the die
Unscrew the knurled screw (11) from the die holder (7).
Take out the die (9).
If necessary, clean the die holder (7). Put a new, well greased die (9) into the die holder. Pay attention to the alignment of the flat side.
Screw back on the knurled screw (11) with the rubber ring (10) attached. Use a hex key to tighten the screw against the resistance of the rubber ring (3–4 Nm).
Changing the punch
Loosen the die holder screw (4) and pull the die holder (7) completely out of the housing.
Slide the punch (8) sideways out of the mounting and pull it out in a downward motion.
Put a new, well greased punch (8) in the groove of the mounting and centre it.
Push the die holder (7) carefully over the punch and back into the housing. Turn the die holder into one of the three possible positions depending on the cutting direction required. Firmly tighten the die holder screw (4).
