• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries. 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 energising power tools that have the switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connect-ed and properly used. Use of dust collection can reduce dust-related hazards.
• 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.

Power tool use and care

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

Battery tool use and care

• 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.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• 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.
• 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.
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.
• 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.

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.

Safety instructions for chain saws

• General 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 saw 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 chain 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.
  • Do not operate a chain saw, 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 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 fibres 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 atch 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 the bar and chain. 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 metal, 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.
  • Do not operate a chain saw in a tree unless you have been specifically trained to do so. Operation of a chain saw in a tree without proper training could increase the risk of 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.
  • 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:

• 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.
• 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 guide bars and saw 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 maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

General chain saw safety warnings

• 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.
• Follow all instructions when clearing jammed material, storing or servicing the chain saw. Make sure the switch is off and the lock-off is in the locked position. Unexpected actuation of the chain saw while clearing jammed material or servicing may result in serious personal injury.

ADDITIONAL SAFETY INSTRUCTIONS FOR ONE HAND POWER SAW

• Keep the one hand power saw out of reach of children. It is not a toy.
• Persons with limited physical, sensorial or mental abilities are not allowed to use the One hand power saw, unless they are supervised for their safety by a qualified person or are briefed by the responsible person how to use the machine.
• Children and adolescents are not allowed to use the one hand power saw. Excluded from this prohibition are young people over 16 years of age under the supervision of an expert for the purpose of training.
• Please note the warning symbols. They mark all those instructions which are important for safety reasons. Observe these instructions as failure to do so could result in serious injury!
• The one hand power saw must be used only by one person at a time. Make sure bystanders do not stay in the vicinity of the one hand power saw’s work area.
• Check the safe operating condition of the One hand power saw, in particular the guide bar and the saw chain, before each operation.
• Always have a safe stand when working with the saw.
• Hold the machine firmly and securely when switching on.
• Make sure the guide bar and the saw chain must be free when switched on and must not come into contact with the workpiece to be cut.
• Keep your hands away from the sawing area. Do not reach under the workpiece. Contact with the saw chain may result in injury.
• Guide the One hand power saw onto the workpiece only when switched on. Otherwise there is a risk of kick-back if the saw chain gets caught in the work piece.
• When sawing, the base plate must always face against the workpiece. The saw chain can become jammed and lead to loss of control over the machine.
• When the cut is completed, switch off the machine and then pull the saw chain out of the cut only after it has come to a standstill. This way you can avoid kick-back.
• Clamp the material to be processed well. Do not support the workpiece with your hand or foot. Do not touch objects or the floor with the saw running. Danger of kick-back.
• When sawing converted timber and thin branches always use a strong support, such as a sawing trestle. Do not stack timber pieces.
• Before cutting logs, secure the logs in position.
• When working on sloping ground, make sure to work facing upwards.
• Be particularly careful when cutting splintered wood. Splinters of wood can be torn along by the saw chain and increase the risk of injury!
• Foreign objects such as nails, screws, metal parts, sand, etc. lead to increased wear on the guide bar and saw chain.
• A blunt saw chain can cause overheating and damage to the motor.
• Always pull out the battery when checking the chain tension, to re-tighten it, to mount the saw chain and to eliminate faults! Also remove the battery if you do not use the machine temporarily

FELL A TREE
Recommendation that the first-time user should, as a minimum practice, start cutting logs on a saw-horse or cradle.

Before you start to fell a tree, make sure that

• The minimum distance between the areas of bucking and felling is two times the height of the tree.
• The operation does not
• Cause injury to personnel.
• Hit utility lines. If the tree touches utility lines, immediately tell the utility company.
• Cause losses in property.
• The user is not in the danger area (24), for example, the downhill side of the area.
• The escape paths (25) that extend back and diagonally behind the felling direction (23) are clear. The felling direction is controlled by
• The natural lean of the tree.
• The location of larger branches.
• The wind direction.
• Ensure there is no dirt, stones, loose bark, nails, and staples on the tree.

1. Make a lower level notching cut (27). Make sure that this cut is

   • 1/3 wide of the diameter of the tree.
   • Perpendicular to the felling direction.
     CAUTION: The level notching cut helps prevent pinching of the saw chain or the guide bar when you make the second notch.

2. Make the felling cut no less than 2 in. (50 mm) and higher than the level notching cut. Make sure that this cut

   • Is parallel to the level notching cut.
   • Keeps sufficient wood to become a hinge (29) which prevents the tree from twisting and felling in the wrong direction. When the felling cut (28) gets near the hinge (29), the tree falls. Stop the felling cut if the tree
   • Does not fall in the correct direction or
   • Moves backwards, causing the cutting bar and chain to become stuck in the cut.

3. Use felling wedge to open the cut and let the tree fall in the correct direction.

4. When the tree starts to fall,

   • Remove the chainsaw from the cut.
   • Stop the machine.
   • Put the machine down.
   • Move away from the tree via the escape path (25). Always keep watching the tree to see it’s direction of fall, be careful with overhead branches and your footing.

LIMB A TREE
Limbing is the removal of the branches from a fallen tree.

1. Keep the larger lower branches to hold the log off the ground (31).
2. Remove the small limbs (30) in one cut.
3. Limb the branches with tension from the bottom to top.
4. Keep the larger lower branches as a support until the log is limbed.

BUCK A LOG
To buck is to cut a log into lengths.
CAUTION: Do not let the chain saw touch the ground. It is important to make sure your footing is secure and your weight is evenly distributed. If possible, lift the log and hold it with branches, logs or chock. Obey the instructions below:

When the log is held along the full length (32), cut it from the top (33).
When the log is held on one end (34), 1. Cut the first time 1/3 of the diameter from the bottom (35). 2. Cut the second time from the top (36) to complete the bucking.

When the log is held on two ends (37)

1. Cut the first time 1/3 of the diameter from the top (36).
2. Cut the second time lower 2/3 from the bottom to complete the bucking (35).

When the log is on a slope,

1. Stand on the uphill side.
2. Control the chain saw completely.
3. Hold the chain saw handles tightly.
4. Release the cutting pressure near the end of the cut.

When bucking is complete (38),

1. Wait for the chain to stop (39).
2. Ensure the chainsaw is turned off.
3. Check for hazards before you move to another tree.

MAINTENANCE

CAUTION: Do not let brake fluids, gasoline, petroleum-based materials touch the plastic parts. Chemicals can cause damage to the plastic, and make the plastic unserviceable.
CAUTION: Do not use strong solvents or detergents on the plastic housing or components.
CAUTION: Remove the battery pack from the machine before maintenance.

SHARPEN THE CUTTERS
Sharpen the cutters if it is not easy for the chain to go into the wood.
NOTE: We recommend that a service center, which has an electric sharpener, perform important sharpening work.

1. Tensioning chain.
2. Sharpen the cutters corner with a 5/32 in. (4 mm) diameter round file.
3. Sharpen the top plate, side plate and depth gauge with a flat file.
4. File all the cutters to the specified angles and the same length.

NOTE:

• During the process:
  • Keep the file flat with the surface to be sharpened.
  • Use the midpoint of the file bar.
  • Use light but firm pressure when sharpening the surface.
  • Lift the file away on each return stroke.
  • Sharpen the cutters on one side and then move to the other side.
• Replace the chain if:
  • The length of the cutting edges is less than 1/5 in. (5 mm).
  • There is too much space between the drive links and the rivets.
  • The cut speed is slow
  • Sharpening the chain many times but it does not increase the cutting speed. The chain is worn.

GUIDE BAR MAINTENANCE
NOTE: Make sure that it is turned over periodically to keep symmetrical wear on the bar.

1. Lubricate the bearings on the nose sprocket (if present) with the syringe (not included).

2. Clean the bar groove with the scraping hook (not included).

3. Clean the lubrication holes.

4. Remove burr from the edges and level the cutters with a flat file.
   Replace the bar if:

   • the groove does not fit with the height of the drive links (which must never touch the bottom).
   • the inside of the guide bar is worn and makes the chain lean to one side.
