V. 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.

VI. Pole saw safety

  1. Keep all parts of the body away from the saw chain. Do not remove cut material or hold material to be cut when the saw chain is moving. Make sure the switch is off and the battery disconnected when clearing jammed material. Saw chain continues to move after the switch is turned off. Before you start the pole saw, make sure the saw chain is not contacting anything.A moment of inattention while operating pole saws may cause entanglement of your clothing or body with the saw chain.

  2. Carry the pole saw by the handle with the saw chain stopped. When transporting or storing the pole saw, always fit the saw chain device cover.Proper handling of the pole saw will reduce possible personal injury from the saw chain.

  3. Hold the power tool 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 power tool ″live″ and could give the operator an electric shock.

  4. Do not use the pole saw in bad weather conditions, especially when there is a risk of lightning.This decreases the risk of being struck by lightning.

  5. To reduce the risk of electrocution, never use near any electrical power lines. Contact with or use near power lines may cause serious injury or electric shock resulting in death.

  6. Always use two hands when operating the pole saw.Hold the pole saw with both hands to avoid loss of control.

  7. Always use head protection when operating the pole saw overhead.Falling debris can result in serious personal injury.

  8. Do not operate a pole saw in a tree.Operation of a pole saw while up in a tree may result in personal injury.

  9. Always keep proper footing and operate the pole 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 pole saw.

  10. 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 saw out of control.

  11. 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.

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

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

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

  15. Avoid 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 toward you.

    Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward you.

    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 pole saw user, you should take several steps to keep your cutting jobs free from accident or injury.

    Kickback is the result of tool 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 saw handles, with both hands on the handle 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 saw.

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

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

Warning

Kickback can cause serious or fatal injury to you.

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

There are 2 types of kickback:

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

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

Figure 10 shows the area of the bar to avoid contacting an object to prevent kickback.

g318677
  1. Grip the pole saw with 2 hands.

  2. Stand on solid, even ground in front of the tree to be trimmed and position yourself for balanced, stable footing while cutting.

  3. 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.

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

  5. Cut with the branch near the rear of the guide bar, close to the cutting guide; press the saw chain lightly against the wood and allow the weight of the pole saw to drive the cutting (Figure 11).

    Important: If the chain binds in the cut, do not attempt to free it by running the motor. Shut off the pole saw, remove the battery, and lift the limb while holding the saw; this should release the pinch and free the pole saw.
