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.

CHAIN SAW SAFETY WARNINGS

• 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 chain.
  ■ 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.
• 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 power tool “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 clothing will reduce personal injury by 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 such as ladders may cause a loss of balance or control of the chain saw.
• 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.

- 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 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. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.

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

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

- 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 chain saw is not intended for tree felling. Use of the chain saw for operations different than intended could result in serious injury to the operator or bystanders.

■ 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 chain saw while clearing jammed material or servicing may result in serious personal injury.

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 (Fig. A).

Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator (Fig. B).

Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator (Fig. C).

Either of these reactions may cause you to lose con-trol 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 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 chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces (Fig. D). Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw.

- 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.

■ 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.

■ Make sure that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, fence, or any other obstruction that could be hit while you are operating the saw.

■ Always cut with the unit running at full speed. Fully squeeze the switch trigger and maintain cutting speed.

■ With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

■ Keep proper footing and balance at all times.

- Push and Pull – The reaction force is always opposite to the direction the chain is moving where wood contact is made. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar, and the PUSH when cutting along the top edge (Fig. E).

KICKBACK SAFETY DEVICES ON THIS CHAIN SAW CHAIN BRAKE

The chain saw comes equipped with a chain brake, which stops both the motor and the motion of the chain when kickback occurs. The chain brake can be activated by the forward motion of the chain kickback brake handle as the saw rotates backward during kickback; it can also be activated by the inertial forces generated during rapid pushback.

WARNING: Never modify or attempt to disable the chain brake.

Make sure that the chain brake is working properly before using the chain saw. The chain kickback brake handle should move back and forth easily.

EN

To test the operation of the chain brake, perform the following steps (Fig. F):

■ Place the chain saw on a flat bare surface and make sure no objects or obstructions that could come in contact with the bar and chain are in the immediate vicinity.
■ Disengage the chain brake by pulling the chain kickback brake handle towards the front handle.
■ Start the chain saw.
■ Push the chain kickback brake handle towards the front of the saw. A properly functioning hand brake will stop the movement of the chain immediately. If the chain brake is not working properly, do not use the chain saw until it has been repaired by a qualified service technician.

WARNING: Confirm that the chain brake works properly before each use.

WARNING: If the chain brake is clogged with wood s, the function of the chain brake may deteriorate. says keep the device clean.

The rakers (depth gauges) ahead of each cutter can minimize the force of a kickback reaction by preventing the cutters from digging in too deeply at the kickback zone. Only use a replacement chain that is equivalent to the original chain or has been certified one.

CAUTION: As saw chains are sharpened during their full life, they lose some of the low kickback qualities extra caution should be used.

ADDITIONAL WARNINGS

■ A chain saw is intended for two-handed use.

Serious injury to the operator, helpers, and/or bystanders can result from one-handed operation.

■ Avoid unintentional contact with the stationary saw chain or guide bar rails. These can be very sharp. Always wear gloves and long pants or chaps when handling the chain saw, saw chain, or guide bar.

■ Never operate a chain saw that is damaged or improperly adjusted or that is not completely and securely assembled. Be sure that the saw chain stops moving when the trigger switch is released.

• Inspect the work piece for nails, wire, or other foreign objects prior to cutting.
  ■ When bucking, secure the work piece prior to cutting. When felling or pruning, identify and secure hazardous branches.
  ■ Aggressive or abusive cutting or misuse of the chain saw can cause premature bar, chain, and/or sprocket wear, as well as broken chain or bar, leading to kickback, chain throw or the ejection of material.

■ Never use the guide bar as a lever. A bent guide bar can cause premature bar, chain, and/or sprocket wear, as well as a broken chain or bar, leading to kickback, chain throw or the ejection of material.

■ Cut only one work piece at a time.
■ Do not charge the battery pack in rain or in wet locations.
■ Plan the work, ensuring an obstacle-free work area and, in the case of felling, at least one escape path from the falling tree.
■ When felling, keep bystanders at least two tree lengths away.
■ If situations occur which are not covered in this manual, use care and good judgment. Contact EGO Customer Service for assistance.

GUIDE BAR

This saw comes equipped with a guide bar that has a small radius nose. Small radius noses generally have less potential for kickback. When replacing the guide bar, be sure to order the bar listed in this manual.
