The guide rail is in a safe condition when the following conditions are met:

• The guide rail is not damaged.
• The guide rail is not deformed.
• The groove bridges are burr-free.
• The groove is neither narrowed nor stretched.

Saw chain
The saw chain is in a safe condition when the following conditions are met:

• The saw chain is not damaged.
• The saw chain is sharpened correctly.
• Wear marks on the cutting teeth are visible.

SAFETY PRINCIPLES OF THE WORK PROCEDURE

• If there are no people in the work area who would hear the call, no help can be given in an emergency.
• Make sure that people are within easy reach of the work area.
• The user can no longer concentrate on their work in certain situations. The user may lose control of the chainsaw, trip, fall and be seriously injured.
• Work calmly and prudently.
• If lighting conditions and visibility are poor: do not work with the chainsaw.
• Operate the chainsaw alone.
• Never work with the machine above shoulder height.
• Watch out for obstacles.
• Stand on the ground and keep your balance when working. If it is necessary to work at heights: use a high-lift work platform or safe scaffolding.
• If signs of fatigue occur, take a work break.
• A running saw chain can cut the user. The user may suffer serious injuries.
• Do not touch the running saw chain.
• If the saw chain is blocked by an object, switch off the chainsaw, activate the chain brake and remove the battery. Only then remove the object.
• The revolving saw chain heats up and stretch-es. If the saw chain is not sufficiently lubricated and additionally tensioned, it can fall off or break from the guide bar. Serious injuries and damage to property can occur.
• Use adhesive oil for saw chains.
• Regularly check the level of the oil tank during operation. Refill the saw chain adhesive oil before it is completely used.
• Regularly check the tension of the saw chain during work. If the chain tension is too weak: Tighten the saw chain.
• If the chainsaw changes or behaves abnormally during operation, it may be in an operationally dangerous condition. Serious injuries and damage to property can occur.
• The chainsaw can cause vibrations during operation.
• Wear gloves.
• Take work breaks.
• If signs of circulatory disorders occur: seek medical advice.
• Sparks can occur if a running saw chain strikes a hard object. Sparks can cause fires in an easily flammable environment. This can lead to serious injuries or death and damage to property.
• Never work in an easily flammable environment.
• When the switch is released, the saw chain runs for a short time. A moving saw chain can cut someone. People can suffer serious injuries.
• Wait for the saw chain to stop.
• Do not touch any part of the saw chain body while the chainsaw is in operation. Before the chainsaw starts, make sure that the saw chain does not touch anything. A moment of inattention while operating a chainsaw can cause the operator’s clothing or body to catch in the saw chain.
• The chainsaw must be held with the right hand behind the rear handle and the left hand behind the front handle. Holding the chainsaw with the hands reversed increases the risk of personal injury and should never be used.
• The chainsaw should only be held by insulated gripping surfaces, as the saw chain may touch a hidden guide or its own power sup-ply. Contact of the saw chains with a “live” wire can cause the uninsulated metal parts of the chainsaw to become “wild” and can result in an electric shock to the user.
• Wear eye protection. Additional work equipment is recommended to protect your hearing, head, hands, lower extremities and feet. Adequate protective equipment reduces the risk of personal injury from flying debris or ac-cidental contact with the saw chain.
• The chainsaw must not be used on a tree, ladder, roof or any unstable base. Working with a chainsaw in this way can result in serious personal injury
• Always adopt the correct position and only operate the chainsaw when the operator is standing on a firm, safe and level surface. Slippery or unstable surfaces can cause the chain-saw to lose balance or control
• Be prepared to jump when cutting a branch that is taut. If the tension in the wood fibres is released, the tensioned branch can strike the operator and/or throw the chainsaw out of control.
• The operator must be extremely careful when cutting shrubs and young trees. Thin material can catch the saw chain and whip towards the operator and throw him/her off balance
• The chainsaw is carried by the front handle, switched off and held away from the body. When guiding or storing the chainsaw, the guide bar cover must always be fitted. Proper handling of the chainsaw will reduce the likelihood of accidental contact with a moving saw chain.
• The instructions for lubricating, tensioning the chain and replacing the guide bar and chain must be followed. An incorrectly tensioned or lubricated chain can either break or increase the possibility of recoil.
• Only wood should be cut. The chainsaw must not be used for purposes for which it is not intended. For example, a chainsaw must not be used to cut metal, plastic, masonry or non-wood building materials. Using the chainsaw for activities other than those for which it is intended can cause a dangerous situation.

REACTION FORCES

Recoil
Recoil can be caused by the following:

• The running saw chain hits a hard object in the upper quarter of the guide bar tip and is quickly deaccelerated.
• The running saw chain is locked at the tip of the guide bar.

The chain brake cannot prevent recoil.
In the event of recoil, the chainsaw can be thrown upwards towards the user. The user may lose control of the chainsaw and be seriously injured or killed. Therefore, it is necessary to:

• Hold the chainsaw firmly with both hands.
• The worker’s body must be outside the ex-tended swing range of the chainsaw.
• Work as described in these operating instruc-tions.
• Never work in the area around the top quarter of the guide bar tip.
• Work with a properly sharpened and ten-sioned saw chain.
• Use a saw chain with a reduced tendency to recoil.
• Use a guide bar with a small bar tip.
• Cut at full throttle.

If a running saw chain hits a hard object and brakes quickly, the chainsaw may suddenly be thrown very hard toward the user. The user may lose control of the chainsaw and be seriously in-jured or killed. Therefore, it is necessary to:

• Hold the chainsaw firmly with both hands.
• Work as described in these operating instruc-tions.
• Guide the guide rail straight in the cut.
• Cut at full throttle.

OPERATION

• WARNING: Always make sure that the tool is switched off, the batteries are removed and the front handguard pushed forward before adjusting or checking the function of the tool.

• WARNING: For your own safety, this tool is equipped with a locking lever that prevents the tool from being started unintentionally. NEVER use the tool while it is running by simply pressing the trigger without pressing the release lever.
  Return the tool to our authorized service centre for proper repair before further use.

• WARNING: NEVER tamper with the tape or impair the purpose and function of the release lever.

• WARNING: Before inserting the battery into the tool, always check that the switch release works properly and returns to the “OFF” position when released.

• WARNING: Do not press the switch trigger firmly without pressing the release lever. This may cause the switch to break.

A locking lever is available to prevent the shutter from being accidentally pressed. To start the tool, press the release lever and press the shutter button. To stop it, release the shutter.

Check the chain brake

WARNING: Hold the chainsaw with both hands when switching it on. Hold the rear handle with your right hand and the front handle with your left. The bar and chain must not be in contact with any object.

ATTENTION: If the saw chain does not immediately stop after performing this test, the saw cannot be used under any circumstances. Contact our authorized service centre.

1. Press the release lever, then press the shutter button. The saw chain starts immediately.
2. With the back of your hand, push the front handguard forward. Make sure that the chainsaw stops immediately.

Deceleration brake check

ATTENTION: If the saw chain does not stop within one second in this test, stop using the chainsaw and contact our authorized service centre. Lower the chainsaw and then release the trigger completely. The saw chain must stop within one second.

Lubrication
The saw chain is automatically lubricated when the tool is in operation. Regularly check the amount of oil remaining through the oil tank window. To refill the tank, place the chainsaw on its side and remove the oil tank cap. The correct amount of oil is 160 ml. After refilling the tank, make sure that the oil tank cap is tight.

After refilling, keep the chainsaw away from the tree. Start it and wait until the saw chain is sufficient-ly lubricated.

• NOTE: When filling the chain with oil for the first time or when refilling the tank after filling, empty the oil completely, topping up the oil to the bottom of the filler neck. Otherwise, the oil supply may be disrupted.
• WARNING: Never use oil that contains dust and particles or volatile oil.
• WARNING: Use vegetable oil when pruning trees. Mineral oil can harm trees.
• WARNING: Before cutting, make sure that the supplied oil tank cap is screwed on.

WORKING WITH A CHAINSAW

• ATTENTION: For the first time, the user should at least practice cutting logs on a sawhorse or cradle.
• ATTENTION: Use a secure support (sawhorse or cradle) when cutting pre-cut wood. Do not hold the workpiece with your feet and do not allow anyone else to hold or touch it.
• ATTENTION: Secure round pieces against rotation.
• ATTENTION: When the engine is running, keep all parts of the body out of the reach of the saw chain.
• ATTENTION: Hold the chainsaw firmly with both hands while the engine is running.
• ATTENTION: Do not exceed the range. Maintain a proper footing and balance.
• NOTE: Never throw or drop the tool on the ground.
• NOTE: Do not cover the ventilation openings of the tool.

Before switching on, bring the lower edge of the chainsaw body into contact with the cut branch. Otherwise, the guide rail may swing and the operator may be injured. Cut the wood by simply moving it down using the weight of the chainsaw.

If you cannot cut the whole wood in one stroke: Press lightly on the handle and continue cutting and pull the chainsaw slightly; then slide the spike bar slightly lower and finish the cut by lifting the handle.

Engaging the saw

1. Place the lower edge of the chainsaw body on the cut wood.
2. With the saw chain running, lift the wood saw and the rear handle and guide the front saw. Use a bar with spikes as a pivot pin.
3. Continue cutting by applying light pressure to the front handle and slightly releasing the saw backwards.Slide the spike bar further down from the wood and lift the front handle again.

• NOTE: When making several cuts, switch off the chainsaw between cuts.
• ATTENTION: If the top edge of the bar is used for cutting, the chainsaw may deflect in your direction if the chain gets caught. Therefore, cut with the lower edge so that the saw deviates from the body.
• When cutting wood under tension, first cut off the pressure side (B). Then make the final cut from the tension side (A). This will prevent the saw from jamming.

Branching

WARNING: Branching may only be performed by trained personnel. There is a risk of recoil. When pruning, support the chainsaw on the log if possible. Do not cut with the tip of the bar as this poses a risk of recoil. Pay extra attention to branches that are under tension. Do not cut unsupported branches from below. Do not stand on the felled trunk when pruning.

Cutting parallel to the grain
WARNING: Cutting parallel to the grain may only be carried out by persons with special training. The possibility of recoil poses a risk of injury. Make cuts parallel to the grain at the smallest possible angle. Be especially careful when cutting, as the tip bar cannot be used.

Felling

ATTENTION: Felling work may only be carried out by trained persons. The work is dangerous. If you want to cut down a tree, observe local regulations.

• Before felling, make sure that:
• Only people involved in the felling are nearby;
• Any person involved has an unblocked retreat path of approximately 45° on either side of the felling axis. Consider the additional risk of tripping over electrical cables;
• The base of the trunk is free of foreign objects, roots and more;
• There are no people or objects at a distance of 2 ½ times the length of the tree in the direction in which the tree falls.
  • For each tree, consider the following:
• Tilt direction;
• Loose or dry branches;
• Height of the tree;
• Natural overhang;
• Whether the tree is rotten or not.
  • Take into account the speed and direction of the wind. Do not cut if there is a strong gust of wind.
  • Trimming root elevations: Start with the largest upright roots. Make a vertical cut first, then a horizontal cut.
  • Stand on the side of the falling tree. Keep the area at the back of the falling tree up to an angle of 45
  • on both sides of the tree axis (see figure “felling area”). Watch out for falling branches.
  • The escape route should be planned and cleared as needed before cutting begins. The escape route should lead backwards and diagonally to the rear of the expected fall line, as shown in the figure.

1. Cutting direction
2. Dangerous area
3. Escape route

Follow these guidelines when felling trees:

1. Cut the trunk as close to the ground as possible. First, make a horizontal cut to a depth of 1/5–1/3 of the trunk diameter. Do not make the notch too big. Then make a diagonal cut.
   Note: The notch determines the direction in which the tree falls and guides it. It is made on the side on which the tree is to fall.

2. Make the back cut slightly higher than the bottom cut of the notch. The back cut must be exactly horizontal. Leave about 1/10 of the trunk diameter between the cut and the notch. The wood grain in the uncut log part acts as a hinge. Insert the wedges into the back cut at the appropriate time.

• WARNING: Under no circumstances should the grain be spun. Otherwise, the tree will fall uncontrollably.
• WARNING: Only plastic or aluminium wedges may be used to keep the notch open. The use of iron wedges is prohibited.

Carrying tools
Always apply the chain brake and remove the batteries from the tool before carrying the tool. Then fasten the guide rail cover.

ASSEMBLY

• ATTENTION: Always make sure that the tool is switched off and the battery is removed before carry-ing out any work on the tool.
• ATTENTION: Do not touch the saw chain with bare hands. Always wear gloves when handling the chain.

Disassembly or installation of the saw chain

WARNING: The saw chain and guide bar are still hot after operation. Let them cool sufficiently before carrying out any work on the tools. Follow these steps to remove the saw chain:

1. Pull the lever while pressing the edge.
2. Turn the lever counterclockwise until the sprocket cover is removed.
3. Remove the sprocket cover, then remove the saw chain and guide bar from the saw body.

Follow these steps to install the saw chain:

1. Check the direction of movement of the chain. The arrow mark on the chain shows the direction of movement of the chain.
2. Place one end of the saw chain on top of the guide bar and the other end around the sprocket.
3. Place the guide bar in place on the chainsaw.
4. Place the sprocket cover on the chainsaw and align the two posts on the cover with the two corre-sponding holes as shown below.
5. Turn the tension knob clockwise and check the chain tension; turn clockwise until properly tensioned. To check the correct tension of the saw chain, pull the saw chain with a force of about 1 kg. If there is a distance between the saw chain and the guide bar of 5-7 mm, as shown below, the tension is correct.
6. Turn the lever clockwise until the sprocket cover is locked, and then return it to its original position.

Saw chain tension adjustment

• ATTENTION: Perform the procedure for installing or removing the saw chain in a clean place free of sawdust and the like.
• ATTENTION: Do not overtighten the saw chain. Excessive tension on the saw chain can cause the saw chain to break, wear the guide bar, and break the tension knob.
• WARNING: An excessively slack chain can jump off the bar and cause injury.
  After many hours of use, the chain may come loose. Check the chain tension from time to time before use.

1. Press and fully open the lever until it clicks. Turn the sprocket cover slightly to loosen it by turning it counterclockwise.
2. Tighten the saw chain by turning the tension knob clockwise until the underside of the saw chain engages in the guide bar as shown in the illustration.
3. Hold the guide bar slightly and tighten the sprocket cover. Make sure that the saw chain on the underside does not come loose.
4. Return the lever to its original position.
   Make sure that the saw chain fits snugly on the underside of the bar.

MAINTENANCE

• ATTENTION: Always make sure that the tool is switched off and the battery is removed before inspection
  and maintenance.

• ATTENTION: Always wear gloves during each inspection or maintenance.

• NOTE: Never use petrol, thinner, alcohol or similar. Change of colour, deformation or cracks may occur.

Sharpening the saw chain

Sharpen the saw chain when:

• * Coarse sawdust is formed when cutting damp wood;

  • The chain penetrates the wood with difficulty, even when strong pressure is applied;
  • The blade is obviously damaged;
  • The saw stretches left or right in the wood. (Caused by uneven sharpening of the saw chain or damage to one side only.)

Sharpen the saw chain regularly, but always lightly.
Two or three file strokes are usually sufficient for routine sharpening. If the saw chain has already been sharpened several times, have it sharpened by an authorized service centre.

Cleaning the guide rail
Chips and sawdust accumulate in the groove of the guide rail. They can block the slot groove and impair oil flow. Clean away chips and sawdust every time you sharpen or replace the saw chain.

Cleaning the sprocket cover
Chips and sawdust accumulate in the sprocket cover. Remove the sprocket cover and saw chain from the tool, then clean away chips and sawdust.

Cleaning the oil drain hole
During operation, small dust or particles may accumulate in the oil drain hole. These can impair the oil flow and cause insufficient lubrication of the entire saw chain. If there is a poor oil supply to the chain at the top of the guide bar, clean the oil drain hole as follows.

1. Remove the sprocket cover and saw chain from the tool.
2. Remove small dust or particles with a flat-blade screwdriver or similar tool.

PREPARATION FOR OPERATION

Use a flat-blade screwdriver to clean the oil hole

1. Insert the battery into the tool. Push the trigger to drain the accumulated oil or particles from the oil drain hole.
2. Remove the battery from the tool. Replace the sprocket cover and saw chain on the tool.

Sprocket Replacement
ATTENTION: A worn sprocket will damage the new saw chain. In this case, have the sprocket replaced. Check the condition of the sprocket before installing a new saw chain.

1. Gear
2. Wear areas

Always use a new circlip when replacing the sprocket.

1. Circlip
2. Gear

WARNING: Make sure the gear is installed as shown in the illustration.

Tool storage

1. Clean the tools before storing them. After removing the sprocket cover from the tool, remove all chips and sawdust.
2. After cleaning the tool, let it lubricate without load – lubricate the saw chain and guide bar.
3. Cover the guide rail with the guide rail cover.
4. Empty the oil tank.
