General Power Tool Safety Warnings

WARNING
Read all safety warnings, instruc-tions, illustrations and specifications provided with this power tool. Failure to follow all in-structions 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 (cord-less) 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 which may ignite the 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 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 exten-sion cord suitable for outdoor use. 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. 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 per-sonal 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. The use of dust collection can reduce dust-related hazards.
• Do not let familiarity gained from the 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.

Noise/Vibration Information
Noise emission values determined according to

EN 62841‑1.
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 62841‑1:ah < 2.5 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 represents 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

• Remove the battery from the power tool before carry-ing out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.

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.

Changing the Tool (see figures B1−B2)

Before removing, allow the blade to cool down.
The blade can become warm during operation.

• Loosen the knurled screw (1) and push the protective guard (3) all the way to the top.
• Use a screwdriver to turn the blade (10) until a hole opens in the blade.
• Insert a thin, stable object (e.g. a nail) in the open hole in order to block the blade.
• Undo the screw for securing the blade (11) in the rotational direction ➊.
• Remove the object used to block the blade.
• Lift the blade (10) slightly and pull it down and out.
• Place the blade on the tool holder with the ground edge facing outwards. Ensure that the blade clicks into place in the tool holder.
• Retighten the screw for securing the blade (11) in rotational direction ➋.
• Adjust the protective guard (3) to the material thickness to be cut and tighten the knurled screw (1).

Adjusting the Protective Guard
Never use the power tool without the protective guard.

To protect your fingers from injuries, the protective guard (3) must be adjusted to the material thickness being cut before each work step. To do this, loosen the knurled screw (1). Adjust the protect-ive guard (3) (in the range 2−11 mm) so that it loosely rests against the material to be cut. Retighten the knurled screw. Adjust the protective guard (3) to the bottom position after each use as well as before all work on the power tool.

Operation

Starting Operation

Inserting the Battery
Insert the charged battery (6) into the battery receptacle, making sure you feel it engage and that it is securely locked in place.

Switching On and Off
To switch on the power tool, slide the on/off switch (4) for-wards so that I appears on the switch.

To switch off the power tool, slide the on/off switch (4) backwards so that 0 appears on the switch.

Practical 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 re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
• Do not load the power tool so heavily that it comes to a stop.
• Never touch the blade during operation.

The cutting performance of the power tool depends on the materials to be cut and on the state of charge of the battery. Excessive feed significantly reduces the performance of the power tool, depending on the battery charge.

The guide runner (12) must be aligned parallel to the cutting surface and must not become wedged during cutting. Always keep the blade clean and free of material residue. Improper use of the blade will cause it to become blunt. Thin materials, such as fabrics, can be pulled into the power tool during cutting and become wedged. To avoid this, do not push too hard when working with thesematerials, in order to ensure an optimal cut. Keep the material taut whilst cutting and cut slowly. Do not remove material that has been inserted during opera-tion. Switch off the power tool with the on/off switch (4) beforehand. Optimal cutting results are best achieved through practice.

Cut Control cutting-line mark
The red line on the protective guard (3) (Cut Control cutting-line mark (2)) indicates the cutting line of the blade (10). This enables you to guide the power tool precisely along the cutting line marked on the material.

Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be overloaded. If the power tool is overloaded or not kept within the permitted battery temperature range, the speed is reduced or the power tool switches off. At reduced speed, the power tool will run again at full speed once the permitted battery temperature is reached or the load is reduced. If it automatically shuts down, switch the power tool off, allow the battery to cool down, then switch the power tool back on.
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 re-moved 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.
