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 (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 sur-faces, 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 suit-able for outdoor use reduces the risk of electric shock.
  If operating a power tool in a damp location is un-avoidable, 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 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 in- juries.

• 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 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 in-jury.

• 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 con-nected and properly used. Use of dust collection can re-duce 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 in-jury 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-signed.

• 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 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 ac-count the working conditions and the work to be per-formed. 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 behavior 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.

• 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

• Measured sound values determined according to EN 62841-1.
• Typically the A‑weighted sound pressure level of the product is lower than 70 dB(A).
• Overall vibrational values ah vector sum of three directions) and uncertainty K determined according 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 standardised measuring procedure and may be used to com-pare 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.

Starting Operation

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

Battery Charging (see figure A)
Note : The battery is supplied partially charged. To ensure full capacity of the battery, completely charge the battery before using your tool for the first time.

• The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging procedure does not cause damage to the battery.
• The Lithium-Ion battery is protected against deep discharging. When the battery is discharged, the tool stops the power-assisted cutting and works in manual mode at all cut-ting diameters.
• The battery needs to be recharged when the battery charge-control indicator (7) briefly flashes red during a cut. Connect the USB connector from the micro USB cable to a power source and insert the micro USB connector (9) into the
• micro USB socket (5) on top of the handle. Charging starts as soon as both connectors are inserted.
• The Micro USB socket (5) can only be accessed when the safety lock (6) is locked.
• The battery charge-control indicator (7) indicates the charging progress. The indicator slowly flashes green during charge process. When the battery charge-control indicator lights up green continuously, the battery is fully charged. During the charging procedure, the handle of the machine warms up. This is normal.
• Disconnect the battery charger from the mains supply when charging process ends.

Battery charge-control indicator

• The battery charge-control indicator (7) indicates the charge condition of the battery while in operation.

LED Capacity

• Continuous lighting, green ≥35 %
• Flashing light, green 5 − 35 %
• Single flash, red 0 − 5 %

Charging Guide

• Please charge before use.
• Charge-control indicator will flash red if:
• Charger is damaged
• Incorrect charger is installed
• The tool has overload protection software. If the software is activated, the tool will lock to prevent damage. To reset the protection software, connect the charger. Before re-use, we recommend to fully charge the tool until the charge-control indicator is continuously green.

Operation

Unlocking (see figure B1)

Deactivate the safety lock (6) by pushing it back. The tool will open and is now ready for use.

Locking

• After usage, close the handles and engage the safety lock (6) by pushing it forward. Always keep in locked position, when not in use.

Gripping position (see figures B2–B4)

• Grip the tool at the front, as shown. Do not grip the tool to-wards the back of the handles or with finger(s) between the handles.

Power-assisted cutting (see figure B)

• This tool provides power-assisted cutting. It is operated like a pair of manual secateurs and will cut in manual mode without power-assisted cutting until a certain branch diameter is reached. The tool will start power-assisted cutting
• when cutting above this branch diameter by starting the integrated motor. Noise development while power-assisted cutting is active, is normal.
  Power-assist feature is only active as long as gripping force is exerted on the handles. If no force is exerted onto the handles, the tool stops.

Working Advice

• Pruning tips (see figures C1–C10)

• Never operate the tool in an awkward posture. This may cause serious injury.

• Keep your free hand away from the cutting area. Never touch the blades. They are very sharp and you may cut yourself.

• C1 Always wear protective gloves while pruning.

• C2 Never cut too close to the stem so the wound can heal properly.

• C3 Always make the cut about 8 mm from the bud.

• C4 The cut should slope away from the bud so the rain can run off.

• C5 If you remove an entire stem, cut back to the point where it branched.

• C6 Never push the blade of the pruner into the ground to cut root suckers.

• C7 Cut branches one by one as shown.
