SAFETY INSTRUCTION FOR PRUNING SAW

• Keep all parts of the body away from the saw chain when the pruning saw is operating. Before you start the pruning saw, make sure the saw chain is not contacting anything. A moment of inattention while operating pruning saws may cause entanglement of your clothing or body with the saw chain.
• Always hold the pruning saw with your one hand on the Grip Area (6) and your other hand on the Secondary Grip Area (3). Holding the pruning saw improperly increases the risk of personal injury and should never be done.
• Hold the pruning 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 pruning saw live and could give the operator an electric shock.
• Wear safety glasses 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 pruning saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a pruning saw in this manner could result in serious personal injury.
• Always keep proper footing and operate the pruning saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the pruning saw.
• When cutting a limb that is under tension, be alert for springback. When the tension in the wood fibers is released, the spring-loaded limb may strike the operator and/or throw the pruning 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 pruning saw with the pruning saw switched off and away from your body. When transporting or storing the pruning saw, always fit the guide bar cover. Proper handling of the pruning 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 chains may either break or increase the chance of kickback. Cut wood only. Do not use pruning saw for purposes not intended. For example: do not use pruning saw for cutting metal, plastic, masonry or non-wood building materials. Use of the pruning saw for operations different than intended could result in a hazardous situation.
• This pruning saw is not intended for tree felling. Use of the pruning 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 pruning saw. Make sure the switch is off and the battery pack is removed. Unexpected actuation of the pruning saw while clearing jammed material or servicing may result in serious personal injury.
• Recommendation that the first-time user should, as a minimum, practice cutting logs on a saw-horse or cradle.
• Recommendation to have sharpening and mainte- nance of the saw chain performed by authorized service centers.

CAUSES AND OPERATOR PRE- VENTION OF KICK-BACK

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 pruning saw user, you should take several steps to keep your cutting jobs free from accident or injury. Kickback is the result of pruning 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 thumbs and fingers encircling the pruning 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 pruning saw.
• Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the pruning saw in unexpected situations.
• Only use replacement bars and chains specified by the manufacturer. Incorrect replacement guide bars and saw chains may cause chain breakage and/or kickback.
• Follow the manufacturer’s sharpening and mainte- nance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

RESIDUAL RISKS

Even with the intended use of the appliance there is always a residual risk, which can not prevent. Accord- ing to the type and construction of the appliance the following potential hazards might apply:

• Contact with exposed saw teeth of the saw chain (cutting hazards)
• Access to the rotating saw chain (cutting hazards)
• Unforeseen, abrupt movement of the guide bar (cutting hazards)
• Flung out of parts from the saw chain (Cutting / injection hazards)
• Flung out of parts of the work piece Skin contact with the oil
• Loss of hearing, if no required ear protection used during work

CUTTING

IMPORTANT

Check recent replaced chain, tension about every 10 minutes during operation.

1. Installing the battery pack into the machine.
2. Make sure section of log to be cut is not laying on the ground. This will keep the chain from touching the ground as it cuts through the log.
3. Touching the ground while the Chain is moving is dangerous and will dull the Chain.
4. When ready to make a cut, push the Lock-Out Button completely in with the right thumb and squeeze the trigger. This will turn saw on. Releasing the trigger will turn the saw off. Make sure the saw is running at full speed before starting a cut.
5. When starting a cut, slowly place moving chain against the wood. The wood should be as close to the saw body as possible. Hold saw firmly in place to avoid possible bouncing or skating (sideways movement) of saw.
6. Guide the saw using light pressure and do not put excessive force on the saw, letting the saw do its work. The motor will overload and can burn out. It will do the job better and safer at the rate for which it was intended.
7. Remove the saw from a cut with the saw running at full speed. Stop the saw by releasing the On/off Switch. Make sure the chain has stopped before setting the saw down.
8. Keep practicing on scrap logs in a secure working area until you are comfortable, using a fluid motion and a steady cutting rate.

KICKBACK SAFETY DEVICES ON THIS SAW

This saw has a low-kickback chain and reduced kickback Guide Bar. Both items reduce the chance of kickback. However, kickback can still occur with this saw.

• The following steps will reduce the risk of kickback.
• Keep all safety items in place on saw. Make sure they work properly.
• Do not overreach or cut above shoulder height.
• Keep solid footing and balance at all times.
• Stand slightly to the left side of saw. This keeps your body from being in direct line with chain.
• Do not let Guide Bar nose touch anything when chain is moving.
• Never try cutting through two logs at same time. Only cut one log at a time.
• Do not bury the Guide Bar nose or try plunge cut (boring into wood using Guide Bar nose).
• Watch for shifting of wood or other forces that may pinch chain.
• Use extreme caution when reentering a previous cut. Use only the low-kickback chain and Guide Bar that were supplied with this pruning saw or recommended.
• Never use a dull or loose chain. Keep chain sharp with proper tension.

HOW TO USE SAW SAFELY

• Use the pruning saw only with secure footing.

• Hold the pruning saw at the right-hand side of your body (See Fia. K).

• The Chain must be running at full speed before it makes contact with the wood.

• Use the Cutting base panel (15) to secure the saw onto the wood before starting to cut.

• Use the Cutting base panel (15) as a leverage point while cutting. (See Fig. L)

• Raise the Chain Guard when cutting from bottom tc top of material. (S ee Fig. M)
  

• Do not operate the saw with arms fully extended, attempt to saw areas which are difficult to reach, or stand on a ladder while sawing. (See Fig. N)

Never use the electric chain saw above shoulder height. Cutting wood under tension (See Fig. O)

WARNING: When cutting a limb that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, limb could spring back and strike operator causing severe injury or death. When sawing logs supported on both ends, start the cut from above(Y) about 1/3 of the diameter into the log (overbuck) and then finish the cut (Z) from below, in order to avoid contact of the electric chain saw with the ground. When sawing logs supported on only one end, start the cut from below (Y) about 1/3 of the diameter into the log (underbuck) and finish the cut from above (Z) in order to avoid log splitting or jamming of the electric chain saw.

MAINTENANCE

SAW MAINTENANCE

   • with Bar and Chain Cover in place

Bar Maintenance

To maximize bar life, the following bar maintenance is recommended. The bar rails that carry the chain should be cleaned before storing the tool or if the bar or chain appear to be dirty. The rails should be cleaned every time the chain is removed.

To clean the Bar rails.

1. Remove Housing-Cover, Bar and Chain. (see section ASSEMBLY)
2. Using a wire brush, screwdriver or similar tool, clear the residue from the inner groove of the bar. (See Fig. R)
3. Make sure to clean oil passages thoroughly. Conditions which require Chain and Guide Bar maintenance:
   • Saw cuts to one side or at an angle.
   • Saw has to be forced through the cut.
   • Inadequate supply of oil to the bar and chain. Check the condition of the Guide Bar each time the chain is sharpened. A worn Guide Bar will damage the chain and make cutting difficult. After each use, remove the battery pack, clean all sawdust from the Guide Bar and sprocket hole. When rail top is uneven, use a flat file to restore square edges and sides.

Replace the Guide Bar when the groove is worn, the Guide Bar is bent or cracked, or when excess heating or burring of the rails occurs. If replacement is necessary, use only the Guide Bar specified for your saw in the repair parts list or on the decal located on the electric chain saw. Replacing Chain Replace chain when cutters are too worn to sharpen or when chain stops. Only use replacement chain noted in this manual. Only handle the saw chain with gloves and remove the battery first! Inspect the saw chain and the guide bar for damage or signs of wear.

Never out a new saw chain on a worn quide bar.

• Unscrew the Housing-cover knob (2) counter-clockwise in order to remove the Housing-cover (11). Unscrew the Chain tensioning screw (14) to release saw Chain (12).

• Remove the old saw Chain (12).

• Round the new saw chain over the Drive sprocket (17) and Guide bar (13).

• Please note the running direction of the saw chain. The saw chain icon is shown on housing nearby Drive sprocket (17).

• Let each new saw chain break-in first!

• When attaching the saw chain, observe the running direction!

SHARPENING SAW CHAIN

WARNING:

Remove the battery pack before servicing. Severe injury or death could occur from electrical shock or body contact with moving chain. Cutting edges on chain are sharp. Use protective gloves when handling chain.Keep chain sharp. Your saw will cut faster and more safely. A dull chain will cause undue sprocket, Guide Bar, chain, and motor wear. If you must force chain into wood and cutting creates only sawdust with few large chips, chain is dull.

INSTRUCTIONS CONCERNING THE PROPER TECHNIQUES FOR LIMBING AND CROSS- CUTTING

1. Limbing a tree
   Limbing is removing the branches from a fallen tree. When limbing leave larger lower limbs to support the log off the ground. Remove the small limbs in one cut as illustrated in Figure 1. Branches under tension should be cut from the bottom up to avoid binding the electric chain saw

2. Bucking a log
   Bucking is cutting a log into lengths. It is important to make sure your footing is firm and your weight is evenly distributed on both feet. When possible, the log should be raised and supported by the use of limbs, logs or chocks. Follow the simple directions for easy cutting. When the log is supported along its entire length as illustrated in Figure 2, it is cut from the top (overbuck), avoid contacting ground as this will greatly reduce the chain sharpness.

When the log is supported on one end, as illustrated in Figure 3, cut 1/3 the diameter from the underside ( underbuck) (1). Then make the finished cut by overbucking (2) to meet the first cut.

When the log is supported on both ends, as illustrated in Figure 4 , cut 1/3 the diameter from the top overbuck) (1). Then make the finished cut by underbucking (2) the lower 2/3 to meet the first cut.

When bucking on a slope always stand on the uphill side of the log, as illustrated in Figure 5. When “cutting through”, to maintain complete control release the cutting pressure near the end of the cut without relaxing your grip on the electric chain saw handles. Don’t let the chain contact the ground. After complet- ing the cut, wait for the saw chain to stop before you move the electric chain saw. Always stop the motor before movina from tree to tree.

TROUBLESHOOTING

TROUBLESHOOTING TABLE

The following table gives checks and actions that you can perform if your machine does not operate correct- ly. If these do not identify/remedy the problem, contact your service agent.
WARNING: Switch off and remove the battery pack before investigating fault.

DISPOSAL
Do not dispose of electric power tools with domestic refuse. The electric power tool is shippedin packaging to reduce transport damage. This packaging is a raw material and as such can either be reused or can be fed back into the raw material cycle. The electric power tool and its accessories are made from various materials such as metals and plastics. Take defective components to a special refuse collection point.Ask about these at your specialist shop or local council.

Batteries

Think of the environment when disposing of batteries. Contact your local authorities to find out where your nearest disposal area is. Do not dispose of batteries with domestic refuse. Do not dispose of by burning, risk of explosion.

CLEANING AND MAINTENANCE

Danger!

Always remove the battery pack before making adjustments to the equipment.

Cleaning

• Keep all safety devices, air vents and the motor housing free of dirt and dust as far as possible. Wipe the equipment with a clean cloth or blow it with compressed air at low pressure.
• We recommend that you clean the device immediately each time you have finished using it. Clean the equipment regularly with a moist cloth and some soft soap. Do not use cleaning agents or solvents; these could attack the plastic parts of the equipment.
• Ensure that no water can seep into the device. The ingress of water into an electric tool increases the risk of an electric shock.

Maintenance

There are no parts inside the equipment which require additional maintenance.

STORING

Store the equipment and accessories in a dark and dry place at above freezing temperature. The ideal storage temperature is between 5 and 30°C. Store the electric tool in its original packaging.
