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. Note: 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 which may ignite the dust or fumes.

707 - 008 - 06.04.2021• 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 extension 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 ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock. Personal safety

• Danger! Do not operate near electrical power lines.The unit has not been designed to provide protection from electric shock in the event of contact with overhead electric lines. Consult local regulations for safe distances from overhead electric power lines and ensure that the operating position is safe and secure before operating the saw chain pole pruner.

• 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.

• 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 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.

• Do not let familiarity gained from frequent use of tools allow you to become complacement and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

• The vibration emission during actual use of the power tool can differ from the declared total value depending on the ways in which the tool is used. Operators should identify safety measures to protect themselves that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger). 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 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.

707 - 008 - 06.04.2021

5• 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 irritations 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 / 265 °F 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. 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.

• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers. Pole pruner safety warnings - personal safety

• Keep all parts of the body away from the saw chain when using the pole pruner. Before you start the pole pruner, make sure the saw chain is not contacting anything. A moment of inattention while operating pole pruners may cause entanglement of your clothing or body with the saw chain.

• Always hold the pole pruner with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.

Hold the pole pruner by insulated gripping surfaces only, because the saw chain may contact hidden wiring or its own cord. Saw chains contacting a "live" wire may make exposed metal parts of the pole pruner "live" and could give the operator an electric shock.

• Wear eye protection. Further protective equipment for hearing, head, hands, legs and feet is recommended. Adequate protective equipment will reduce personal injury from flying debris or accidental contact with the saw chain.

• Do not operate a chain saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a chain saw in this manner could result in serious personal injury.

• Always keep proper footing and operate the chain saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the pole pruner.

• When cutting a limb that is under tension, be alert for spring back. When the tension in the wood fibres is released, the spring loaded limb may strike the operator and/or throw the pole pruner out of control.

• Use extreme caution when cutting brush and saplings. The slender material may catch the pole pruner and be whipped toward you or pull you off balance.

• Follow instructions for lubricating, chain tensioning and changing the bar and chain. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.

• Carry the pole pruner by the front handle with the pole pruner switched off and away from your body. When transporting or storing the pole pruner, always fit the guide bar cover. Proper handling of the pole pruner will reduce the likelihood of accidental contact with the moving saw chain.

• Cut wood only. Do not use pole pruner for purposes not intended. For example: do not use pole pruner for cutting metal, plastic, masonry or non-wood building materials. Use of the pole pruner for operations different than intended could result in a hazardous situation.

• Keep handles dry, clean and free from oil and grease. Greasy, oily handles are slippery causing loss of control.

• Do not attempt to fell a tree until you have an understanding of the risks and how to avoid them. Serious injury could occur to the operator or bystanders while felling a tree.

• This pole pruner is not intended for tree felling.Use of the pole pruner for operations different than intended could result in serious injury to the operator or bystanders.

• We strongly recommend that first time users practice sawing logs on a saw horse or cradle.

707 - 008 - 06.04.2021Causes and operator prevention of kickback

Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the pole pruner in the cut. Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator. Pinching the pole pruner along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the pole pruner which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your pole pruner. As a pole pruner user, you should take several steps to keep your cutting jobs free from accident or injury. Kickback is the result of pole pruner misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• Maintain a firm grip, with thumbs and fingers encircling the pole pruner handles, with both hands on the pole pruner and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the pole pruner.

• Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the pole pruner in unexpected situations.

• Only use replacement guide bars and pole pruners specified by the manufacturer.Incorrect replacement guide bars and pole pruners may cause chain breakage and/or kickback.

• Follow the manufacturer’s sharpening and maintenance instructions for the pole pruner. Decreasing the depth gauge height can lead to increased kickback. General pole pruner safety warnings Follow all instructions when clearing jammed material, storing or servicing the pole pruner. Make sure the switch is off and the battery pack is removed. Unexpected actuation of the pole pruner while clearing jammed material or servicing may result in serious personal injury. Personal protective equipment

Observe great care when working close to overhead power lines. Falling branches can result in short circuiting.

• Whenever possible, position yourself so that you can make the cut at right angles to the branch.

707 - 008 - 06.04.2021

13• Cut large branches in sections so that you have better control over where they fall. You should also pay attention to the fact that falling branches can bounce in the direction of the user after hitting ground.

• Never cut through the swelling at the root of the branch as this will slow down healing and increase the risk of fungal attack.

• Use the stop at the base of the cutting head to provide support during cutting. This will help prevent the cutting attachment from bouncing on the branch.

• Make an initial cut on the underside of the branch before cutting through the branch. This will prevent tearing of the bark, which could lead to slow healing and cause permanent damage to the tree. The cut should not be deeper than ⅓ of the branch thickness to prevent jamming. Keep the chain running while you withdraw the cutting attachment from the branch to prevent it jamming.

• Make sure you have a firm footing and that you can work without being hampered by branches, stones and trees.

If the saw chain is blunt, you must apply more pressure to push the guide bar through the wood. If the saw chain is very blunt, there will be no wood chips but sawdust. A sharp saw chain eats through the wood and the wood chips becomes long and thick. The cutting tooth (A) and the depth gauge (B) together makes the cutting part of the saw chain, the cutter. The difference in height between the two gives the cutting depth (depth gauge setting).

When you sharpen the cutter, think about the following:

• Round file diameter. It is not easy to sharpen a saw chain correctly without the correct equipment. Use Husqvarna file gauge. This will help you to keep maximum cutting performance and the kickback risk at a minimum.

WARNING: The force of the kickback

increases a lot if you do not follow the sharpening instructions. Note: Refer to To sharpen the cutters on page 18 for information about sharpening of the saw chain. To sharpen the cutters

1. Use a round file and a file gauge to sharpen the

cutting teeth. Note: Refer to Accessories on page 24 for information about which file and gauge that Husqvarna recommends for your saw chain.

2. Apply the file gauge correctly on to the cutter. Refer

to the instruction supplied with the file gauge.

3. Move the file from the inner side of the cutting teeth

and out. Decrease the pressure on the pull stroke.

4. Remove material from one side of all the cutting

5. Turn the product around and remove material on the

707 - 008 - 06.04.20216. Make sure that all cutting teeth are the same length.

General information about how to adjust the depth gauge setting The depth gauge setting (C) decreases when you sharpen the cutting tooth (A). To keep maximum cutting performance you must remove filing material from the depth gauge (B) to receive the recommended depth gauge setting. See Technical data on page 23 for instructions about how to receive the correct depth gauge setting for your saw chain.

WARNING: The risk of kickback

increases if the depth gauge setting is too large! To adjust the depth gauge setting Before you adjust the depth gauge setting or sharpen the cutters, refer to General information about how to sharpen the cutters on page 18 , for instructions. We recommend you to adjust the depth gauge setting after each third operation that you sharpen the cutting teeth. We recommend that you use our depth gauge tool to receive the correct depth gauge setting and bevel for the depth gauge.

1. Use a flat file and a depth gauge tool to adjust the

depth gauge setting. Only use Husqvarna depth gauge tool to get the correct depth gauge setting and bevel for the depth gauge.

2. Put the depth gauge tool on the saw chain.

Note: See the package of the depth gauge tool for more information about how to use the tool.

3. Use the flat file to remove the part of the depth

gauge that extends through the depth gauge tool. To adjust the tension of the saw chain

WARNING: A saw chain with an

incorrect tension can come loose from the guide bar and cause serious injury or death. A saw chain becomes longer when you use it. It is important to adjust the tension of the saw chain regularly to make sure that it is correct. Do a check of the tension of the saw chain before you operate the product. Tighten the saw chain as tightly as possible, but it must be possible to pull the saw chain around freely by hand. Note: A new saw chain has a running-in period. Do a check of the tension more frequently during this period.

1. Turn the locking knob counterclockwise to unlock the

chain tension adjuster.

2. Turn the chain tension adjuster clockwise to tighten

the saw chain. Apply as much tension to the saw chain as possible. It must be tight against the guide bar.

3. Make sure that you can pull the saw chain around

freely by hand and that it does not hang from the guide bar.

4. Turn the locking knob clockwise to lock the chain

tension adjuster. To lubricate cutting equipment

Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries.
