IMPORTANT SAFETY

INSTRUCTIONS

I. Work area safety

  1. Keep work area clean and well lit.Cluttered or dark areas invite accidents.

  2. 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.

  3. Keep children and bystanders away while operating a power tool.Distractions can cause you to lose control.

II. Electrical safety

  1. 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.

  2. 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.

  3. Do not expose power tools to rain or wet conditions.Water entering a power tool will increase the risk of electric shock.

  4. 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.

  5. 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.

  6. 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.

III. Personal safety

  1. 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.

  2. Use personal protective equipment. Always wear eye protection.Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions reduces personal injuries.

  3. 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.

  4. 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.

  5. Do not overreach. Keep proper footing and balance at all times.This enables better control of the power tool in unexpected situations.

  6. 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.

  7. 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.

  8. 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.

IV. Power tool use and care

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. Keep cutting tools sharp and clean.Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

  7. 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.

  8. 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.

V. Battery tool use and care

  1. 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.

  2. Use power tools only with specifically designated battery packs.Use of any other battery packs may create a risk of injury and fire.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

VI. Service

  1. 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.

  2. Never service damaged battery packs.Service of battery packs should only be performed by the manufacturer or authorized service providers.

VII. Chain saw safety

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

  2. Always hold the chain saw 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.

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

  4. 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.

  5. 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.

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

  7. When cutting a limb that is under tension, be alert for spring back.When the tension in the wood fibers is released, the spring loaded limb may strike the operator and/or throw the chain saw out of control.

  8. Use extreme caution when cutting brush and saplings.The slender material may catch the saw chain and be whipped toward you or pull you off balance.

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

  10. 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.

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

  12. 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.

  13. Follow all instructions when clearing jammed material, storing or servicing the chain saw. Make sure the switch is off and the battery pack is removed.Unexpected actuation of the machine while clearing jammed material or servicing may result in serious personal injury.

  14. Causes 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 saw chain 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 saw chain 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 saw, which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

    Kickback is the result of chain saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

    1. Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw 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 chain saw.

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

    3. Only use replacement guide bars and saw chains specified by the manufacturer.Incorrect replacement guide bars and saw chains may cause chain breakage and/or kickback.

    4. Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.Decreasing the depth gauge height can lead to increased kickback.

Cutting with the Chain Saw

Warning

Operating a chain saw improperly can cause serious personal injury or death.

Read and follow all operating instructions carefully to avoid possible personal injury.

Warning

Kickback can cause serious or fatal injury to you.

Always ensure that the chain brake system is working properly before you operate the chain saw.

Avoid touching objects to be cut with the nose of the chain saw guide bar.

There are 2 types of kickback:

  • A fast upward motion of the chain saw that results when the chain at the nose or top of the bar contacts an object

  • A fast backward motion of the chain saw that results when the chain at the nose or top of the bar is pinched by the object being cut

Figure 12 shows the area of the bar to avoid contacting an object to prevent kickback.

g318677
  1. Grip the chain saw with 2 hands, with your left hand on the front handle and your right hand on the rear handle as shown in Figure 13.

    Important: Keep your left arm straight with your elbow locked to help reduce kickback.

    g025213
  2. Stand on solid, even ground in front of the wood to be cut.

  3. Stand to the left side of the chain saw, not in line with the chain, and position yourself for balanced, stable footing while cutting.

    Important: Do not stand on the wood that you are cutting.

  4. Ensure that you only cut the wood that you intend to cut; do not allow the saw chain to contact the earth, other logs, or any other objects when cutting.

  5. Ensure that the saw chain is rotating at full speed before starting a cut.

  6. Cut with the wood near the rear of the guide bar, close to the bucking teeth; press the chain saw lightly against the wood and allow the weight of the chain saw to drive the cutting.

    Note: You can use the bucking teeth (Figure 14) to apply light pressure.

    g315747
  7. Keep steady pressure on the chain saw, cutting in a straight line, and release pressure only near the end of the cut.

Pruning a Tree

Warning

Cutting higher limbs from a tree off the ground can put you in an unstable position that could be unsafe for you while handling a chain saw, resulting in possible serious personal injury or death to you or bystanders.

When cutting limbs from a standing tree, use the following practices:

  • Do not climb on limbs or branches with a chain saw.

  • Do not overreach, and cut with both hands on the chain saw.

  • Ensure that all bystanders are away from the area where branches may fall.

  1. Grip the chain saw as shown in Figure 13.

  2. While cutting small branches, apply light pressure to the branch to be cut.

  3. While cutting larger branches, make a shallow undercut and then complete the cut from the topside of the branch.

    1. Cut from the underside of the limb about 15 cm (6 inches) from the trunk. Cut a third of the way through the limb.

    2. Cut 5.0 to 10.0 cm (2 to 4 inches) farther out on the limb and from above. Cut the limb until it falls.

    3. Cut the limb stub at the branch collar (Figure 15).

      Important: Do not cut the limb past the collar, flush to the trunk, or leave a large limb stub; this damages the tree.

      g316577

Felling a Tree

Warning

Cutting standing trees requires expertise and poses hazards.

  • Before attempting to cut a big tree, practice cutting a few branches, limbs, or small logs to familiarize yourself with the chain saw.

  • Do not use this chain saw to fell large trees with a diameter larger than the length of the guide bar.

Danger

Loose or tangled limbs above you may be dislodged by vibration from cutting, causing severe injury or death.

Always look overhead for loose and tangled limbs before cutting; if you see any loose limbs or branches, remove them before cutting.

The proper operator stance for felling a tree is shown in Figure 16.

g195831
  1. Determine the direction that the tree will fall. Take the following variables into consideration:

    • Wind direction

    • Heavier limbs on 1 side of the tree

    • Natural tilt of the tree (if any)

  2. Determine a clear, safe retreat path away from the danger area; refer to Figure 17.

    g024800
  3. Grip the chain saw as shown in (Figure 13).

  4. Make the first cut a third of the way through the tree diameter on the side where you want the tree to fall (Figure 18).

    Note: Making this cut prevents the chain saw from being pinched while making the next cut.

    g228707
  5. Make a second cut to form a notch, starting the cut at least 5 cm (2 inches) above and away from the first cut (Figure 18).

    Important: Ensure that the first cut and the second cut meet at the same point, forming a clean notch.

  6. Make the back cut from the opposite side of the notch and about 5 cm (2 inches) higher than the bottom of the notch as shown in Figure 18.

    Important: Stop the third cut 2.5 to 5.0 cm (1 to 2 inches) from the notch to form a hinge between the cuts (Figure 18), which keeps the tree from falling in the wrong direction or twisting as it falls.

    Note: As the back cut nears the hinge (Figure 18), the tree should begin to fall.

  7. When the tree begins to fall, remove the chain saw, shut it off, put it down, and retreat along the path you determined in step 2.

    Important: If the tree begins to fall in an undesired direction, immediately stop the cut, shut off the chain saw, put the chain saw down, and use a non-metallic wedge to open the back cut and push the tree in the desired direction.

Limbing a Fallen Tree

  1. Grip the chain saw as shown in Figure 13.

  2. Moving from the base of the tree up, cut off the smaller limbs from the tree that are not supporting its weight off the ground (Figure 19).

  3. Cut the larger limbs that support the weight of the tree from the bottom upward so that the limbs do not pinch the saw blade (Figure 20).

    g316601
    g315751

Bucking a Log

When bucking a log, note where the log is supported and where there is a load on the log. Cut the log so that when the ends fall, your guide bar will not be pinched between them.

Important: If the chain saw binds in the cut, do not attempt to free it by running the motor. Shut off the saw, remove the battery, then use a wedge to pry open the cut and release the saw.

If you are cutting branches from a fallen tree or cutting a log into lengths, support the log off the ground (preferably on a sawbuck).

  • If the log is supported on both ends, but not in the middle, the load is on the center of the log.

    • Start from the top and cut about a third of the way through the log (Figure 21A).

    • Make a second cut from the underside to meet the first cut (Figure 21B). This keeps the log from pinching the saw.

    g315765
  • If the log is supported on a single end, the load is on the free end of the log.

    • Start from the underside and cut about a third of the way through the log.

    • Make a second cut from the top to meet the first cut. This keeps the log from pinching the saw.

  • If the log is supported off the ground along its entire length, without a heavy load on the log at any point, cut all the way through the log from the top.

  • If the log is on a hill, always stand on the uphill side of the log (Figure 22).

    g315767
  • If the whole length of the log is supported on flat, level ground, cut a third of the diameter from the top, then roll the log over and make another cut to meet the first cut (Figure 23).

    g315766

Installing the Battery Pack

Important: Use the battery pack only in temperatures that are within the appropriate range; refer to Specifications.

  1. Set the chain saw down on a level surface.

  2. Align the tongue of the battery pack with the battery cavity in the chain saw (Figure 24).

    A loose chain shortens the life of the drive sprocket and the guide bar and may cause the chain to fall off.

    An overtightened chain overheats the guide bar and chain, causing rapid wear, and may burn out the motor or break the chain.

    The chain tension is correct when you are able to use a gloved hand to pull the chain smoothly around the guide bar. The chain should remain in contact with the bottom edge of the guide bar.

    Also, check the chain tension of a new chain after a few cuts; a new chain usually stretches and requires adjustment after a few cuts.

    Danger

    Contact with the chain saw teeth can cause serious personal injury.

    • Remove the battery pack before adjusting or maintaining the chain saw.

    • Always wear gloves when adjusting or maintaining the chain saw.

    1. Place the chain saw on a level surface and remove the battery pack; refer to Removing the Battery Pack.

    2. Allow the saw chain to cool.

      Important: Do not tension a hot chain; it may contract as it cools, resulting in an overtightened chain.

    3. Inspect the guide bar for bends or damage, replace if necessary.

    4. Ensure that the chain brake is in the OPERATING position (Figure 28).

    5. Using the onboard multitool, loosen the captive nuts on the side cover, but do not remove it (Figure 31).

    6. Hold up the tip of the guide bar (Figure 30).

      g315842
    7. Using the onboard multitool, adjust the chain tension, and then secure the side cover to the chain saw by tightening the captive nuts (Figure 31).

      • To tighten the chain, turn the chain tensioning screw clockwise (Figure 30).

      • To loosen the chain, turn the chain tensioning screw counterclockwise

      Adjust the chain tension until the chain touches the bottom edge of the guide bar, then pull the chain away from the bottom edge of the guide bar; a properly adjusted chain can only be pulled 3.2 to 6.4 mm (1/8 to 1/4 inch) away from the guide bar, and snaps back on release.

      If the chain is not properly tensioned, loosen the side cover and repeat steps 5 through 8.

    8. Use a gloved hand to pull the chain around the guide bar. A properly tensioned chain should move smoothly and remain in contact with the bottom edge of the guide bar.

    9. Check the chain tension again and repeat this procedure if necessary.
