General safety notices
CAUTION!: When working with tools that use fu-el, the following basic rules must be followed in order to minimise the risk of physical injury and/or damage to the machine.
Read these notices before using the saw, and store them safely.

1. Do not use the saw when you are tired, ill or under the influence of alcohol and/or drugs.
2. Be careful when handling fuel. Use the saw at a distance of at least 3m from the fuel-filling location.
3. Start cutting only when the working environment has been tidied, when you have established secure footing and planned an escape route from the falling tree.
4. Before starting the chainsaw, make sure it is not in contact with any objects.
5. Carry the chainsaw only when the motor has stopped running, the blade cover is on the chain bar and the exhaust is facing away from you.
6. Do not start a chainsaw that is damaged, incorrectly set up or assembled incompletely or loose-ly. Ensure that the chainsaw stops when the chain brake is activated.
7. Turn off the motor before putting the chainsaw down.
8. When cutting small bushes and saplings, be particularly careful because the thin branches can become caught in the saw and be ejected towards you or unbalance you.
9. When cutting a branch under tension, be aware of potential kickback when the tension is suddenly released.
10. Ensure that handles are dry, clean and free from oil or fuel.
11. Do not cut trees with this chainsaw unless you have the relevant training.
12. The overall maintenance of this chainsaw, apart from the points specified in this manual and these maintenance instructions, must be carried out by an authorised customer service.
13. For transport and storage of the chainsaw, fit the blade cover to the chain bar.
14. Do not work with the chainsaw next to or in the presence of flammable liquids or gases, neither indoors nor outdoors. There is a risk of explosion and/or fire.
15. Do not fill with fuel, oil or lubricant when the chainsaw is running.
16. Only cut suitable material: Only cut timber. Do not use the chainsaw for work for which it is not suitable. Do not use the chainsaw for cutting plastic, masonry or building materials which are not made of wood, for example.
17. The power tool produces poisonous exhaust fumes as soon as the motor starts. Never work in closed or badly-ventilated rooms.
18. In order to locate significant damage or faults, it is necessary to inspect the machine before use and in case you drop it.
19. If liquid is spilled when filling the oil or fuel tank, the machine must be cleaned before use.

As a chainsaw user, you must follow several points in order to carry out your sawing work without accidents and injuries.

1. A basic understanding of kickback can reduce or exclude the element of surprise. Sudden rash re-actions can lead to accidents.
2. When the motor is running, hold on to the saw tightly with both hands, with the right hand on the handle at the back and the left hand on the han-dle at the front. Thumbs and fingers must firm-ly clasp the chainsaw‘s handles. A secure hold helps you to absorb kickback and keep the saw under control. Do not let go.
3. Ensure that the area where you are cutting is free from obstacles. The tip of the chain bar must not come in contact with tree trunks, branches and similar when cutting with the saw.
4. Use a fast motor speed.
5. Do not lean too far forwards and do not cut above your shoulder height.
6. Sharpen and maintain the chainsaw in accordance with the manufacturer‘s instructions.
7. If the tool becomes jammed during cutting, it has to be turned off immediately and freed carefully. Afterwards, the machine has to be checked for damage (e.g. bent chain bar) and a test run has to be carried out.

To cut with the chainsaw, place the stop directly on the wood to be cut. It is also recommended to use the stopper claw to cut branches of large diameter.
The stopper claw is firmly attached to the wood before cutting with a running chainsaw. Lift the end of the chain saw with the rear handle and guide it with the bow handle. The claw serves as a fulcrum. The transfer takes place by lightly pressing the handle. The saw can thus be easily withdrawn. Insert the claw and raise the rear handle again.
Use only admitted chain saw and chain bar combination!

The cutting equipment supplied is optimally matched to this chain saw.
When pairing of components do not match, the cutting attachment can be irreparably damaged after only a short operating time and cause injury.

NOTICE
The following information is mainly for the end user or the infrequent user. This chainsaw has been designed for occasional use by home owners, garden owners and campers, for general work such as clearing, cutting firewood etc. It is not intended for longer work. During longer work, because of vibrations, there is a risk of circulation problems in the user‘s hands (white-finger syndrome). White-finger-syn-drome is a vascular disease where the small blood vessels in fingers and toes contract seizure-like. The affected areas are no longer supplied with blood and therefore look very pale.

Frequent use of vibrating machines can cause nerve damage in people whose circulation is compromised (e.g. smokers, people with diabetes).
If you notice unusual impairment, immediately stop the work and consult a doctor. Observe the following notices in order to reduce risks:

• Keep your body, and particularly your hands, warm in cold weather.
• Take regular breaks during which you should move your hands to promote circulation.
• Ensure the lowest possible vibration of the ma-chine by regularly maintaining it and keeping components tight.

Personal safety

• Never use only one hand when using the saw! Otherwise there is a risk that operating staff, helpers or onlookers may get injured. A chainsaw has been designed for use with both hands.
• Wear your Personal Protective Equipment (PPE), consisting of: Cut-resistant shoes, cut-protection trousers, hi vis vest or jacket in signal colours, gloves and a helmet with visor and hearing protection.
• When starting the chainsaw or cutting with it, no other people should be close to you. Ensure on-lookers and animals cannot get into the working environment.
• When the motor is running, all body parts must point away from the chainsaw.

Safety notices for handling flammable fuels

1. WARNING!: Petrol is easily flammable!
2. Store petrol in containers that have been designed specially for this purpose.
3. Refill with petrol when you are outdoors, and do not smoke.
4. Refill with petrol before starting the motor. Never remove the fuel tank filler cap or refill with petrol while the motor is running or when it is still hot.
5. When fuel has been spilled, do not start the motor but remove the machine from the area of the spilled fuel and avoid all ignition sources until all petrol fumes have dispersed. Put the cap back securely on the fuel tank and on the canister.

Refueling

• Turn off the motor before refuelling.
• CAUTION! Always open the fuel filler cap carefully so the existing pressure can be released slowly.
• High temperatures are generated on the casing during work. Before refuelling, allow the machine to cool down fully.
• CAUTION! If the machine has not cooled down sufficiently, the fuel could ignite during refuelling and cause severe burns.
• Ensure that the tank is not overfilled. If you spill any fuel, it has to be wiped away immediately and the machine must be cleaned.
• Always close the screw plug on the fuel tank properly, so loosening is prevented from vibrations during operation.

DANGER: Never refuel the machine close to an open flame.
Special safety regulations for the use of internal combustion motors

DANGER: Internal combustion motors are a particular danger during operation and refuelling. Always read and follow the warnings. Non-compliance can lead to severe and even lethal injuries.

1. Do not make any modifications to the machine.
2. CAUTION! Risk of poisoning, Exhaust fumes, fuel, Lubricating oil vapor, sawdust and lubricants are poisonous. Exhaust fumes must not be inhaled.
3. CAUTION! Risk of burns!, Do not touch the exhaust system and the drive motor.
4. Do not use the machine in unventilated rooms or easily flammable environments.
5. Risk of explosion! Never use the machine in rooms with easily flammable substances.
6. During transport, secure the tool against sliding and tilting.
7. Ensure that no fuel is spilled on the motor or the exhaust during refuelling.
8. Repairs and setting work must be carried out by authorised specialists.
9. Do not touch mechanically moving or hot parts. Do not remove protective covers.
10. The values specified in Technical Data under sound power level (LwA) and sound pressure level (LpA) are emission levels and do not necessarily represent safe working levels. As there is a connection between emission and immission levels, it cannot be used reliably to determine potentially required, additional safety measures. Factors influencing the current employee‘s immission level include characteristics of the working environment, other noise sources etc. such as the number of machines and other nearby processes and the time frame the user is exposed to the noise. The reliable immission level can also vary by country. However, this information will give the machine‘s user the opportunity to carry out a better risk assessment.
11. Never put objects into the venting slots. This also applies when the machine is turned off. Non-compliance can cause injuries or damage to the machine.
12. Keep the tool free from oil, dirt and other contaminants.
13. Ensure that sound absorbers and air filters function properly. These parts act as flame protection in the event of misfire.
14. Turn off the motor:
    • Whenever you leave the machine
    • Before refuelling.
15. Never use the choke lever to stop the motor.

Safety functions of the chainsaw (Fig.1)

• 1 SAW-CHAIN WITH LOW KICKBACK helps you with specially developed safety devices to reduce kickback forces so you can absorb them better.
• 3 FRONT HAND GUARD protects the left hand of the operator if it slides off the front handle when the saw is running.
• 3 CHAIN BRAKE is a safety function to reduce in-jury based on kickback by stopping a running saw chain within milliseconds. It is activated by the FRONT HAND GUARD.
• 8 THROTTLE TRIGGER LOCKOUT prevents accidental acceleration of the motor. The throttle can be activated only when the throttle trigger interlock is pressed.
• 11 ON/OFF SWITCH immediately stops the motor when it is switched off. The stop switch must be turned to ON to start the motor (again).
• 18 CHAIN CATCHER reduces the risk of injury if the saw-chain breaks or slips when the motor is running. The chain catcher is designed to catch a flail-ing chain.

NOTICE: Familiarise yourself with the saw and its components.

Warning notices for chainsaws

• When the saw is running, keep all body parts away from the saw chain. Before starting the saw, ensure that nothing touches the saw chain. When working with a chainsaw, a moment of carelessness can cause clothing or body parts to be caught by the saw chain.
• Do not work with this chainsaw on a tree unless you are specially trained for this. In the event of improper use of a chainsaw on a tree, there is a risk of injury.
• When cutting a branch under tension, expect it to spring back. When the tension is released, the branch can hit the operator and/or take away control of the chainsaw.
• Be particularly careful when cutting under-growth and young trees. Thin material can get caught in the saw-chain and be ejected in your di-rection or make you lose your balance.
• Carry the chainsaw by the front handle with the saw-chain not moving and the guide bar pointing backwards. During transport and storage of the chainsaw always attach the safety cover. Careful handling of the chainsaw reduces the likelihood of accidentally touching the running saw-chain.
• Follow the instructions for lubrication, chain tension and replacement of accessories. An im-properly tensioned or lubricated chain can either break or increase the kickback risk.
• Keep handles dry, clean and free from oil and grease. Greasy, oily handles are slippery and cause loss of control.

Causes and prevention of kickback:

• Kickback can occur when the tip of the guide bar touches an object or when the timber bends and the saw chain becomes caught in the cut.
• Contact with the guide bar tip can, in some cases, lead to an unexpected backwards reaction in which the guide bar is thrown up and in the direction of the operator.
• If the saw chain becomes caught at the top of the guide bar, the guide bar can quickly kick back towards the operator.
• Each of these reactions can cause you to lose control over the saw and potentially to get severely injured. Do not exclusively trust the safety devices built into the chainsaw. As the user of a chainsaw, you should take different measures to work accident and injury free.

Kickback is the consequence of incorrect or erratic use of the machine. It can be prevented by appropriate safety measures such as described below:

• Hold the saw with both hands, ensuring thumbs and fingers clasp the handles of the chainsaw. Position your body and arms in such a way that you can withstand kickback forces. If appropriate measures are taken, the operator can control kickback forces. Never let go of the chainsaw.
• Avoid an abnormal body posture and do not saw above shoulder height. This prevents accidental contact with the tip of the guide bar and it enables better control of the chainsaw in unexpected situations.
• Always use replacement guide bars and saw chains specified by the manufacturer. Incorrect replacement guide bars and saw chains can cause breaking of the chain and/or kickback.
• Follow the manufacturer‘s instructions concerning sharpening and maintenance of the saw chain. Over-reduction of depth limiters increases kickback tendency.

Safety notices for maintenance/storage
Have your machine repaired by qualified specialists and only with original spare parts. This ensures the safety of the machine.

1. Before use, always visually check the tool for wear and tear or damage. Replace worn or damaged components and bolts. Tighten all nuts, bolts and machine screws to ensure that the equipment is in a safe operating condition.
2. Regularly check the fuel system for leakage or signs of abrasion, for example from porous fuel lines, loose or missing clamps and damage to the tank or the tank lid. All faults must be resolved before use. (see chapter 13)
3. Before checking or adjusting the machine or the motor, remove the spark plug or the ignition cable, respectively, to prevent accidental start-up.

Storage

1. Never store the equipment with fuel in the tank inside buildings where the fumes can come into contact with open fire or sparks.
2. Before storing the chainsaw in a closed room, al-low the motor to cool down.
3. In order to reduce the risk of fire, keep the motor sound absorbers and fuel storage area free from organic material and excessive lubricant.

Long-term storage/packing away for winter
If you are storing the machine long-term or for winter, remove all the fuel. Fuels are chemical compounds that change their properties when stored long-term. Removing the fuel must take place outdoors.

Do not store and use the chainsaw at temperatures below 0 ° C!

WARNING: Improper maintenance or non-compliance or not resolving a problem can become a hazard during operation. Only ever work with machines that have been serviced regularly and properly. This is the only way you can ensure that you can run your machine safe-ly, economically and without problems.
Do not clean, service, adjust or repair the tool when it is running. Moving parts can cause severe injuries. Do not use petrol or other flammable solvents to clean the machine components.

WARNING

• Fumes from fuel and solvents can cause explosions.
• After repairs and maintenance work, re-attach the safety devices to the machine.
• Ensure the machine is operational, in particular, check the fuel system for leak-tightness.
• Always clear the motor‘s cooling fins of contamination.

DANGER: The manufacturer of this equipment shall be not li-able to the applicable Product Liability Act for dam-ages arising in this device or this unit at:

• Installation and replacement of non-original spare parts,
• Removal or alteration of safety components.

Operating instructions

Important notices

1. Turn off the motor if the saw comes in contact with foreign objects. Check the saw and, if applicable, repair it.
2. Protect the chain from dirt and sand. Even small quantities of dirt can quickly make the chain blunt and increase the risk of kickback.
3. Start by cutting up smaller logs to practise in order to get a feel for the device, before attempting difficult tasks.
4. Activate the throttle at maximum, before starting sawing.
5. Press the casing of the chainsaw against the log when starting sawing.
6. Run the device at full throttle throughout the whole sawing process.
7. Let the saw do the work. Only use slight down-wards pressure.
8. Release the throttle as soon as you have finished your work so the motor runs idle. If you let the machine run at full throttle without load, there will be unnecessary wear and tear.
9. So that you do not lose control of the device after the chain exits the wood, you should not apply any pressure to the saw towards the end of the cut.
10. Check after starting the idle setting. The cutting blade must be stationary during idling. If the cutting tool is moving when the device is in idle, the idle speed must be reduced (see “Setting the idle speed”).
11. Turn off the device before putting it down.
12. If the device becomes jammed whilst cutting, it must be turned off immediately and carefully freed. Then the device should be checked for damage (e.g. bent-guide bar) and then a trial run should be carried out.
13. Before carrying out the final cut, check to ensure that there are no bystanders, animals or obstacles are in the area where debris may land.
14. Branches that are tensioned must be cut from underneath in an upwards motion in order to ensure that the chainsaw does not become jammed.
15. In order to maintain full control at the moment of cutting all the way through, reduce the pressing force towards the end of the cut, without loosen-ing your firm grip of the handles of the chainsaw. Ensure that the saw chain does not come into contact with the ground.

Kickback

• When working with the chainsaw, you may en-counter a hazardous kickback.
• This kickback arises if the top area of the guide bar accidentally comes into contact with wood or an-other solid object.
• Before the chainsaw is guided into the cutting ar-ea, it can slip away to the side or jump up.
• (ATTENTION!: Increased risk of kickback!)
• The chainsaw could be thrown or pushed towards the operator in an uncontrolled manner and with high energy (risk of injury!).

Observe the following in order to avoid kick-backs:

• Plunge work (directly plunging the tip of the bar in-to the wood) may only be performed by specially trained personnel!
• Always watch the tip of the bar. Take care when continuing cuts which have already been started.
• Start the cut with the chainsaw running!
• Always sharpen the saw chain correctly. Pay particular attention to the depth limiter being at the correct height!
• Never cut through several branches at the same time! When removing branches, ensure that no other branch is touched.
• When cutting to length, pay attention to closely ad-jacent branches.

Felling trees – only with relevant training

CAUTION: Watch out for broken or dead branches which may fall down during sawing and which could cause severe injuries. Do not saw close to buildings or power lines if you do not know in which direction the felled tree will fall. Do not work at night because you can see less well, or during rain, snow and storms be-cause the direction in which the tree will fall cannot be anticipated.

• Plan your work with the chainsaw in advance.
• The working environment around the tree should be cleared so you have secure footing.
• The machine operator should always be positioned at a higher level in the working area because the tree will probably roll or slide down after felling.

The following conditions can influence the tree‘s falling direction:

• Wind direction and speed
• Leaning of the tree – The leaning direction cannot always be recognized because of uneven or sloping ground. Determine the leaning direction of the tree using a plumb line or a level.
• Branches growing (and therefore weight) only on one side
• Surrounding trees or obstacles

Look out for destroyed or decayed parts of the tree. If the trunk is decayed, it can suddenly break and fall on you. Make sure there is sufficient space for the falling tree. Keep a distance of 2½ tree lengths to the next person or other objects. The sound of the motor can drown out warning cries.
Remove dirt, stones, loose bark, nails, brackets and wire from the sawing area.

Ensure you have a free escape route (Fig. A)
Position 1: Escape route
Position 2: Falling direction of the tree

Felling of large trees – only with relevant training (from 15cm diameter)
The undercutting method is used for felling large trees. For this, a wedge is cut out from the side of the tree according to the required falling direction. After the dropping cut has been made on the other side of the tree, it will fall in the direction of the wedge cut.

NOTICE: If the tree has large prop/buttress roots, these should be removed before the wedge is cut. If the saw is used for removing the prop/buttress roots, the saw-
chain should not touch the ground so the chain does not become blunt.

Undercut and felling the tree (Fig. B-C)

• For the undercut, first cut the upper part (Pos. 1) of the wedge (Pos. 2). Cut 1/3 of the way into the tree. Then saw the lower part (Pos. 3) of the wedge (Pos. 2). Now remove the wedge you have cut out.
• Afterwards, you can carry out the dropping cut on the opposite side of the tree (Fig. 4). For this, start about 5cm above the middle of the cut. In this way, there is enough wood between the dropping cut (Pos. 4) and the wedge (Pos. 2) so that it functions as a hinge. This hinge is designed to guide the tree in the right direction when falling.

NOTICE: Before completing the dropping cut, if required, increase the cut using wedges to control the direction of the fall. Exclusively use wood or plastic wedges. Steel or iron wedges can cause kickback and damage to the device.

• Be aware of signs that the tree is beginning to fall: Cracking sounds, the dropping cut opening or movement in the upper branches.
• When the tree begins to fall, stop the saw, put it down and leave immediately via your escape route.
• To prevent injuries, do not cut partly felled trees with your saw. Beware especially of partly felled trees which are not supported. If a tree does not fall down completely, remove the saw and help the process along with a cable winch, a pulley or a towing vehicle.

Sawing a felled tree (log division)
The term „log division“ describes the cutting up of a felled tree into logs of the desired length.

CAUTION: Do not stand on the log you are currently cutting. The log could roll away and you may lose your foot-ing and control of the device. Do not carry out sawing work on sloping ground.

Important notices

• Only ever saw one log or branch.
• Be careful when cutting split wood. You may be hit by sharp pieces of wood.
• Cut small logs or branches on a sawhorse. When cutting logs, no other person must hold on to the log.
• Do not secure the log with your leg or foot. Do not use the saw in areas where logs, roots and other parts of the tree are entangled. Pull the logs to a free area and cut the freed logs first.

Different cuts for log division (Fig. D)

CAUTION: If the saw is jammed in a log, do not pull it out with force. You may lose control of the device and suffer severe injuries and/or damage the saw.
Stop the saw and drive a plastic or wooden wedge into the cut until the saw can be pulled out easily. Restart the saw and carefully continue with the cut. Never start the saw when it is jammed in a log.

Topping (Fig. E, Pos. 1)
Topping starts at the upper side of the log where you hold the saw against the log. Only use slight down-wards pressure for topping.

Undercut (Fig. E, Pos. 2)
Start the undercut on the underside of the log and hold the top edge of the saw against the log. Only use slight upwards pressure for the undercut. Hold the saw securely to control the device. The saw will push backwards (in your direction).

CAUTION: Never hold the saw the wrong way round for an undercut. You do not have control of the device in this position. Always make the first cut on the compression side of the log. The compression side of the log is where the pressure of the log‘s weight is concentrated.

Log division without supports (Fig. F)

• Using topping (Pos. 1), saw 1/3 of the way into the tree.
• Turn the log around and make a second top cut (Pos. 2).
• When sawing on the compression side, make sure the saw does not get jammed. See Figure for cuts in logs on the compression side.

Log division with log or support (Fig. G-H)

• Always remember to make the first cut (Pos. 1) on the loaded side of the log.
• Cut 1/3 into the log for this.
• Make a second cut (Pos. 2).

Trimming and pruning

CAUTION: Always be careful and protect yourself from kick-back. Never let the moving chain at the tip of the chain guide come in contact with other branches or objects during trimming or cutting branches. Such contact can lead to serious injuries.

CAUTION: Never climb into the tree for trimming or pruning. Do not stand on ladders, platforms etc. You could lose your balance and control of the device.

Important notices

• Work slowly and hold on to the saw with both hands. Ensure a secure standing position and balance.
• Beware of recoiling parts of the tree. Practise extreme caution when cutting small parts of the tree. Flexible material can get caught in the saw chain and be ejected in your direction or make you lose your balance.
• Beware of recoiling parts of the tree. This particularly applies to bent or loaded branches. Avoid coming in contact with the branch or the saw when the tension on the wood is released.
• Keep your working area clear. Clear the path of branches so you do not trip over them.

Trimming

• Do not start trimming the tree before it has been felled. Only then can you carry out the trimming safely and properly.
• Leave larger branches underneath the felled tree and use them as a support while you continue working.
• Start at the foot of the felled tree and work your way up to the top. Remove smaller parts of the tree with one cut.
• Make sure that the tree is always between you and the saw.
• Remove larger, supporting branches using the method from Section „Log division without support “.
• Always remove small freely suspended parts of the tree with a top cut. They may fall into the saw or trap it if you use an undercut.

Pruning (Fig. K)

CAUTION: Prune branches only at or below shoulder height. Never cut branches above shoulder height. Leave that kind of work to a professional.

• For the first cut (Pos. 1), cut 1/3 of the way into the lower part of the branch.
• Then cut all the way through the branch with the second cut (Pos. 2). The third cut (Pos. 3) is a top cut with which you separate the branch from the trunk at a distance of 2.5 to 5cm.

• Only use appliances which are in perfect working order.
• Service and clean the appliance regularly.
• Adapt your working style to suit the appliance.
• Do not overload the appliance.
• Have the appliance serviced whenever necessary.
• Switch the appliance off when it is not in use.
• Wear protective gloves.

Before starting up

CAUTION!: Start the engine only when the saw is fully assembled.
CAUTION!: When handling the chain always wear protective gloves.

Assembling the bar, and the chain (Fig.3-6)
Open the box and assemble the bar and chain as follows:

1. Press the front hand guard back (Fig.14/Pos.3a) so that the chain brake is disabled.

2. Loosen the two nuts (B) and remove the cover (17) and spacer (A).

3. Mounting the stopper claw (Fig.3)
   Insert the stopper claw (19) into the recesses of the housing (see Fig. 3) and secure with the 2 fixing screws (19a). Use the tool supplied with the assembly tools (10).

4. Slide the chain around the sprocket, next slide the saw chain around the bar. Pay attention to the installation direction of the chain. (Fig.4-5)

5. Insert the chain tensioning screw (Z) into the lower hole of the chain bar (Y). (Fig.4)

6. Install the cover (17) and tighten the nuts (B) by hand.

Installation direction of the chain (shown Fig.5)
Tensioning the chain (Fig.6-8)

1. Hold the front part tight with your hand.
2. Adjust the chain tension using the tension screw (C) so that the chain rests entirely on the bar, but not under great tension.
3. Tighten the mounting nut (B) for the bar with the key (12-15 Nm).
4. Check with your hand that the chain runs smoothly on the rail and has the proper voltage.
5. Where necessary, set up the chain tension

If the chain has to be re-tensioned

Adjusting the chain tension
Correct saw chain tension is extremely important and must be checked before starting operation and at regular intervals during all sawing work. If you take the time to adjust the saw chain, you will improve your sawing results and extend the chain’s service life.

NOTE: If the chain is too loose or too tight on the drive wheel and bar, the crankshaft bearings will wear out faster.

NOTE: New chains expand, so they must be reset after about 5 cuts. This is normal for a new chain, and the future interval settings will decrease.

Fuel and Chain Oil
WARNING!: Fuel and chain oil are highly flammable. Do not smoke and or expose the unit to an open flame when you use the device.

Fuel
For optimal results, use normal unleaded fuel (max. 5% Bio-ethanol) blended with special 2-stroke oil.

Fuel mixture
Mix the fuel with 2-stroke oil in a suitable container. Shake the container to mix everything carefully.

CAUTION!: Never use pure gasoline for this saw. It will damage the engine and you will lose the warranty for this product. Do not use a fuel mixture that has been stored for longer than 90 days.
CAUTION!: Special 2-stroke oil must be used for air-cooled 2-stroke engines with a 40:1 ratio. Insufficient oil will damage the engine and, in this case, void the warranty for the motor.

FUEL MIXING TABLE
Mixing ratio: 40 parts petrol to 1 part 2-stroke oil.

Petrol    2-stroke oil
1 Liter     25 ml
5 Liter    125 ml

After filling the fuel and chain oil tanks, close the tank lid by hand.
Do not use tools to do so.

Recommended fuels
Some conventional gasolines are blended with ingredients such as alcohol or ether compounds to meet the standards for clean exhaust gases. The engine runs satisfactorily with all grades of gasoline, but for the purpose of self- propulsion with oxygenated gasoline, it is best to use regular gasoline. At best, use regular unleaded fuel (max. 5% Bio-ethanol).

Oiling of the chain and bar
Every time the fuel tank is filled with gasoline, oil must also be added to the chain oil tank.
It is recommended to use commercial chain oil.

1. Put the machine to the side (Housing cover saw chain drive unit (17))
2. Remove the oil tank cap (14) and fuel tank cap (12).
3. Fill the chain oil tank (Fig.9/Pos.D1) to 80% with chain oil.
4. Pour the petrol-/oil mixture into the fuel tank (Fig.9/Pos.D2).
5. Close Oil tank cap (14) and fuel tank cap (12).

Chain Brake (Fig.14)
NOTE: Before each use always check that the chain brake is functioning.

• Hold the chain saw by the front handle (4).
• Press the front hand guard (3) forward to position (3b). Press the pedal, the chain should not move.
• Pull the front handle (3) back to position (3a). Press the pedal, the chain should move.

Oil Supply Control
To check the chain lubrication keep the chain on a piece of paper and give full throttle for a few seconds. On the paper the quantity of oil can be checked.

• Clean the spark plug with a copper wire brush or replace it with a new one. (Fig.22)

Adjusting the idling speed (Fig. 25)
If the saw chain continues to idle, you must correct the idle speed.

1. Remove the plug (T).
2. Let the engine warm up for 3-5 minutes (no high speeds!).
3. Turn the adjusting screw (R) using a flat-head screwdriver: clockwise
– Idle speed increases (+)
counterclockwise
– Idle speed decreases (-) Idling speed max.: 3500 min-1

Saw chain

Saw chain Tension
Periodically check the chain tension and adjust if necessary, so that after use the chain is snug against the rail, but still loose enough that it can be pulled by hand. (Fig.8)
Breaking in a new saw chain
A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the breakin period, and the interval between future adjustments will begin to lengthen quickly.

Chain lubrication
Always make sure the automatic oiler system is working properly. Keep the oil tank filled with Chain, Bar and Sprocket Oil.
Adequate lubrication of the bar and chain during cut-ting operations is essential to minimize friction with the guide bar.
Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease cut-ting efficiency, shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar discoloration.

Maintaining the chain

Sharpening the chain
Special tools are required to sharpen the chain; these ensure that the cutting tools are sharpened at the correct angle and to the correct depth. We recommend that inexperienced chainsaw users have the saw chain sharpened by a specialist at the nearest customer service location. If you are confident with sharpening your own saw chain, procure the special tools from professional customer service.

Sharpening the chain
Wear safety gloves when sharpening the chain. All cutting links must have the same width and length after sharpening.

Important hint in case of sending the equipment to a service station:
Due to security reasons please see to it that the equipment is sent back free of oil and gas!

Instructions for periodic maintenance
To ensure long life, prevent damage and ensure the full functioning of the safety features the following maintenance must be performed regularly. Guarantee claims can be recognized only if this work is performed regularly and properly. Failure to perform the prescribed maintenance work can lead to accidents! The user of the chain saw must not perform maintenance work which is not described in the instruction manual.
All other work may only be performed by a specialist workshop.
