PRODUCT SAFETY WARNINGS

Safety instructions for the saw

• Keep all parts of the body away from the saw chain when the saw is operating. Before you start the saw, make sure the saw chain is not contacting anything. A moment of inattention while operating the saw may cause entanglement of your clothing or body with the saw chain.
• Hold the 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 saw “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.
• Always keep proper footing and operate the saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the saw.
• 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 saw out of control.
• 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.
• Carry the saw by the handle with the saw switched off and away from your body. When transporting or storing the saw, always fit the guide bar cover.
• Proper handling of the saw will reduce the likelihood of accidental contact with the moving saw chain.
• 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.
• Cut wood only. Do not use saw for purposes not intended. For example: do not use saw for cutting metal, plastic, masonry or non-wood building materials. Use of the saw for operations different than intended could result in a hazardous situation.
• This saw is not intended for tree felling. Use of the saw for operations different than intended could result in serious injury to the operator or bystanders.

Causes and operator prevention of kick-back

• Kick-back 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 saw user, you should take several steps to keep your cutting jobs free from accident or injury.
• Kick-back is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:
  • Maintain a firm grip, with thumb and fingers encircling the saw handle and position your body and arm to allow you to resist kick-back forces. Kick-back forces can be controlled by the operator. if proper precautions are taken. Do not let go of the saw.
  • 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 kick-back.
  • Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kick-back.

Additional safety instructions for one hand power saw

• The one hand power saw is designed for cutting branches. Only use the one hand power saw as indicated in this manual for cutting wood. The machine has not been designed for continuous, professional use.
• Keep the one hand power saw out of reach of children. It is not a toy.

3. Remove the battery and check the chain tension again. If necessary, retighten the chain.
4. Afterwards make only easy cuts for approx. 30 minutes. Always ensure sufficient lubrication of the saw chain! Only use the one hand power saw for heavier cuts and greater cutting depths after the running-in period has expired.

• Use only sharp saw chains. Blunt saw chains can jam more easily. Check the chain tension more frequently when working with new saw chains, as the chain stretches more at first.
• The service life of a saw chain depends on sufficient lubrication and the correct tension.
• During operation, the chain heats up and re-tensioning may be necessary. Relax the chain after work so that it is not too tight the next time the cold machine is used.
• Do not re-tighten saw chains that have become too hot. After it has cooled down, it may contract and lie too tight against the sword. Wait until the saw chain has cooled down before re-tensioning.
• The tension of the saw chain is important for your safety and the function of the machine. A correctly tensioned saw chain increases the service life of the machine.
• Check the chain tension before each use.
• The saw chain is correctly tensioned if it can be pulled around the sword by hand (wear protective gloves) without sagging.
• With new saw chains, you must readjust the chain tension again after a short period of operation.

Work instructions

• Never reach over the riving knife or under the base plate. There is a risk of injury!
• Do not cut if the saw chain is in contact with the workpiece, is in the workpiece or may hit an object. This can lead to serious injuries.
• Clamp loose workpieces before cutting them. Remove foreign objects such as nails, screws, etc.
• When cutting a branch 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 machine out of control.
• 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.
• When the saw chain is running. First place the base plate on the surface of the workpiece and let the saw cut on its own. Apply only light pressure to the saw. The chain speed should not be much slower.
