Change your clothes. Move the machine at least 3 metres away from the refuelling area before starting.

General working instructions

WARNING! This section describes basic

!safety directions for using a power cutter. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsafe, stop and seek expert advice. Contact your dealer, service agent or an experienced power cutter user. Do not attempt any task that you feel unsure of!

Basic safety rules

???Look around you:

-To ensure that people, animals or other things cannot affect your control of the machine.

-To make sure that none of the above come into contact with the cutting blade.

???Do not use the machine in bad weather, such as dense fog, rain, strong wind, intense cold, etc. Working in bad weather is tiring and can lead to dangerous conditions, e.g. slippery surfaces.

???Never start to work with the power cutter before the working area is clear and you have a ???rm foothold. Look out for any obstacles with unexpected movement. Ensure when cutting that no material can become loose and fall, causing operating injury.Take great care when working on sloping ground.

???Make sure that no clothes or parts of the body come in contact with the cutting equipment when it is rotating.

???Keep at a safe distance from the cutting equipment when it is rotating.

???The guard for the cutting equipment must always be on when the machine is running.

???Ensure that the working area is suf???ciently illuminated to create a safe working environment.

WARNING! Do not move the machine when

!the cutting equipment is rotating.

???Always ensure you have a safe and stable working position.

???Make sure that no pipes or electrical cables are routed in the area to be cut.

WARNING! Only use the machine in areas

!with good ventilation. Neglect can result in serious injury or death.

Cutting

WARNING! The safety distance for the power

!cutter is 15 metres. You are responsible to ensure that animals and onlookers are not within the working area. Do not start cutting until the working area is clear and you are standing ???rmly.

General

???Start cutting with the machine running at maximum speed.

???Always hold the machine in a ???rm grip with both hands. Hold it so that the thumbs and ???ngers grip round the handles.

WARNING! Overexposure to vibration can

!lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. These symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition.These symptoms normally appear in the ???ngers, hands or wrists.

Cutting technique

The technique described below is of a general character. Check information for each blade regarding individual cutting characteristics (for example, diamond blades requires less feeding pressure than an abrasive discs).

???Support the work piece in such a way that it is possible to predict what will happen, and so that the cut remains open while cutting.

???Check that the blade is not in contact with anything when the machine is started

???Always cut at maximum speed.

???Start cutting smoothly, allowing the machine to work without forcing or pressing in the blade.

???Move the blade slowly forwards and backwards to achieve a small contact area between the blade and the material to be cut. This reduces the temperature of the blade and ensures effective cutting.

???Feed down the machine in line with the blade. Pressure from the side can damage the blade and is very dangerous.

???The guard for the cutting equipment should be adjusted so that the rear section is ???ush with the work piece. Spatter and sparks from the material being cut are then collected up by the guard and led away from the user.

WARNING! Under all circumstances avoid

!grinding using the side of the blade; it will almost certainly be damaged, break and can cause immense damage. Only use the cutting section.

Do not pull the power cutter to one side, this can cause the blade to jam or break resulting in injury to people.

Sharpening diamond blades

Diamond blades can become dull when the wrong feeding pressure is used or when cutting certain materials such as heavily reinforced concrete. Working with a blunt diamond blade causes overheating, which can result in the diamond segments coming loose.

Sharpen the blade by cutting in a soft material such as sandstone or brick.

Blade vibration

The blade can become out-of-round and vibrate if an excessive feed pressure is used.

A lower feed pressure can stop the vibration. Otherwise replace the blade. The blade must be of the recommended type for the material to be cut.

How to avoid kickback

WARNING! Kickback can happen very

!suddenly and violently; kicking the power cutter and cutting blade back at the user. If this happens when the cutting blade is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique.

What is kickback?

The word kickback is used to describe the sudden reaction that causes the power cutter and cutting blade to be thrown from an object when the upper quadrant of the blade, known as the kickback zone, touches an object.

General rules

???Never start to cut with the upper quadrant of the blade as shown in the ???gure, also known as the kickback zone.

???Always hold the machine in a ???rm grip with both hands. Hold it so that the thumbs and ???ngers grip round the handles.

???Keep a good balance and a ???rm foothold.

???Always cut at maximum speed.

???Stand at a comfortable distance from the work piece.

???Take care when inserting the blade in an existing cut.

???Never cut above shoulder height.

???Be alert to movement of the work piece or anything else that can occur, which could cause the cut to close and pinch the blade.

Pull in

Pull in occurs when the disc???s lower section suddenly stops or when the cut closes. (To avoid, see the heading ???Basic rules??? and ???Jamming/rotation???, here below.)

Pinching/rotation

If the cut is pressed together this can lead to jamming. The machine can be pulled down suddenly with a very powerful jerk.

How to avoid pinching

Support the work piece in such a way that the cut remains open during the cutting operation and when the cut is ???nished.

Cutting blades

WARNING! A cutting blade may burst and

!cause injury to the operator.

Never use a cutting blade at a lower speed rating than that of the power cutter.

Never use a cutting blade for any other materials than that it was intended for.

WARNING! Cutting plastics with a diamond

!blade or rescue blade can cause kickback when the material melts due to the heat produced when cutting and sticks to the blade.

General

Cutting blades are available in two basic designs; abrasive discs and diamond blades.

Always remove the cutting blade when the machine is transported.

Make sure that the right bushing is used for the cutting blade to be ???tted on the machine. See the instructions under the heading Assembling the cutting blade.

High-quality blades are often most economical. Lower quality blades often have inferior cutting capacity and a shorter service life, which results in a higher cost in relation to the quantity of material that is cut.

Water cooling

WARNING! Water cooling, which is used

!when cutting concrete, cools the blade and increases its service life while also reducing the formation of dust. Disadvantages include dif???culties at very low temperatures, the risk of damaging ???oors and other structural elements, and the risk of slipping.

After using an abrasive disc with water cooling, run the disc dry for about half a minute. If an abrasive disc is stored in humid conditions, this can cause imbalance and result in injury.

High speed handheld machines

Our cutting blades are manufactured for high-speed, portable power cutters. If blades from other manufacturers are used, ensure that the blades conform to all regulations and demands that concern this type of power cutter.

Special blades

Some cutting blades are designed for stationary equipment and for use with attachments.Such cutting blades must not be used on portable power cutters.

Always contact local authorities and make sure you are following applicable directives.

Abrasive discs

The cutting material on abrasive discs consists of grit bonded using an organic binder. ???Reinforced blades??? are made up of a fabric or ???bre base that prevents total breakage at maximum working speed if the blade should be cracked or damaged.

A cutting blade???s performance is determined by the type and size of abrasive corn, and the type and hardness of the bonding agent.

Abrasive discs, types and use

Check that the blade is approved for the same or higher speed according to the aproval plate of the engine. Never use a cutting blade with a lower speed rating than that of the power cutter.

Ensure the blade it not cracked or damaged in any other way.

Test the abrasive disc by hanging it on your ???nger and tapping it lightly with a screwdriver or the like. If the disc does not produce a resonant, ringing sound it is damaged.

Diamond blades

Diamond blades consist of a steel body provided with segments that contain industrial diamonds.

Diamond blades ensure lower costs per cutting operation, fewer blade changes and a constant cutting depth.

When using diamond blades make sure that it rotates in the direction indicated by the arrow on the blade.

Always use a sharp diamond blade. Sharpen the blade by cutting in a soft material such as sandstone or brick.

Diamond blades are available in several hardness classes. A "soft" diamond blade has a relatively short service life and large cutting capacity. It is used for hard materials such as granite and hard concrete. A "hard" diamond blade has a longer service life and reduced cutting capacity, and should be used for soft materials such as brick and asphalt.

Material

Diamond blades are ideal for masonry, reinforced concrete and other composite materials. Diamond blades are not recommended for cutting metal.

Diamond blades for wet cutting

WARNING! Cool diamond blades for wet

!cutting continuously with water to prevent overheating, which can cause the blade to break up and eject pieces that can cause injury.

Diamond blades for wet cutting should have water poured over them during the cutting to cool the blade and bond the dust.

Diamond blades for dry cutting

Diamond blades for dry cutting are a new generation of blades that do not require water cooling. However, the blades will still be damaged by excessive heat. It is most economical to allow the blade to cool by simply lifting it out from the cut every 30???60 seconds and letting it rotate in the air for 10 seconds.

Checking the drive axle and ???ange washers

Check that the threads on the drive shaft are undamaged.

Check that the contact surfaces on the blade and the ???ange washers are undamaged, of the correct dimension, clean, and that they run properly on the drive axle.

Do not use warped, notched, indented or dirty ???ange washers. Do not use different dimensions of ???ange washers.

Fitting the cutting blade

Husqvarna???s blades are approved for hand-held power cutters. Blades are manufactured with three different diameters of centre holes: 20 mm (0.787"), 22.2 mm (7/8") and 25.4 mm (1"). Bushings can be ???tted on the machine axle to adjust the machine to the centre hole of the blade. Use a bushing with the correct diameter! The blades are marked with the diameter of the centre hole.

The blade is placed on the bushing (C) between the inner ???ange washer (A) and the ???ange washer (B). The ???ange washer is turned so that it ???ts on the axle.

Tightening torque for the bolt holding the blade is: 15-25 Nm (130-215 in.lb).

The shaft can be locked using a screwdriver, steel pin or the like. This is slid in as far as possible. The blade is tightened clockwise.

When a diamond blade is mounted on the power cutter make sure that the diamond blade will rotate in the direction indicated by the arrow on the blade.

When the blade is replaced with a new one, check the ???ange washers and the drive axle. See instructions under the heading Checking the drive axle and ???ange washers.

Guard for the blade

The guard must always be ???tted on the machine. The guard for the cutting equipment should be adjusted so that the rear section is ???ush with the work piece. Spatter and sparks from the material being cut are then collected up by the guard and led away from the user.

Fuel

CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two- stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

WARNING! Always ensure there is adequate

!ventilation when handling fuel.

Petrol

???Use good quality unleaded or leaded petrol.

???The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 so-called knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage.

Two-stroke oil

???For best results and performance use HUSQVARNA two- stroke engine oil, which is specially formulated for our air- cooled two-stroke engines.

???Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

???Never use oil intended for four-stroke engines.

Mixing ratio

1:50 (2%) with HUSQVARNA two-stroke oil or equivalent.

1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.

Mixing

???Always mix the petrol and oil in a clean container intended for fuel.

???Always start by ???lling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol.

???Mix (shake) the fuel mixture thoroughly before ???lling the machine???s fuel tank.

???Do not mix more than one month???s supply of fuel at a time.

???If the machine is not used for some time the fuel tank should be emptied and cleaned.

Fuelling

WARNING! Taking the following precautions,

!will lessen the risk of ???re:

Do not smoke or place hot objects near fuel.

Always shut off the engine before refuelling.

When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Tighten the fuel cap carefully after refuelling.

Always move the machine away from the refuelling area before starting.

???Keep the handle dry and free from oil and fuel.

???Ensure that the fuel is well mixed by shaking the container before ???lling the tank.

???Always exercise care when re???lling the fuel. Move the machine at least three metres from the fuelling area before it is started. Check that the fuel cap is tightened correctly.

???Clean around the fuel cap. Clean the fuel and oil tank regularly. The fuel ???lter should be changed at least once a year. Contamination in the tanks causes malfunction.

Starting and stopping

WARNING! Note the following before

!starting:

Do not start the power cutter without the belt guard ???tted. Otherwise the clutch could come loose and cause personal injuries.

Always move the machine away from the refuelling area before starting.

Ensure that you and the machine have a good working stance and that the cutting blade can rotate freely.

Keep people and animals well away from the working area.

Starting a cold engine

Ignition: Slide the ignition switch to the left.

Choke: Pull the choke control fully out.

Starting a warm engine

Use the same starting procedure as for a cold engine but without setting the choke control in the choke position.

Starting

WARNING! The cutting blade rotates when

!the engine is started. Make sure it can rotate freely.

Grip the front handle with your left hand. Put your right foot on the lower section of the rear handle pressing the machine against the ground. Never twist the starter cord around

your hand.

Grip the starter handle, slowly pull out the cord with your right hand until you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord.

CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.

When the engine starts, quickly apply full throttle to automatically disengage fast idle.

Stopping

The engine is stopped by switching the ignition off using the stop switch.

Tensioning the drive belt

???The drive belt is fully enclosed and well protected from dust and dirt.

???When the drive belt is to be tensioned, release the bolts holding the cutting arm.

???Screw the adjuster screw so that the square headed nut comes opposite the marking on the cover. This automatically ensures that the belt has the correct tension.

???Tighten both of the screws holding the cutting head using a T-wrench.

IMPORTANT INFORMATION The tension of a new drive belt must be readjusted after one or two tanks of fuel have been used.

Replacing the drive belt

???First release the two bolts and then the adjuster screw to release the belt tension.

???Now unscrew the bolts and dismantle the belt guard.

???Remove the belt from the belt pulley.

???The cutting head is now loose and can be removed from the machine. Remove the rear belt guard by releasing the two screws holding the guard.

???Replace the drive belt.

???Assemble in the reverse order as set out for dismantling.

???Check that the guard over the cutting blade is not cracked or damaged in any other way. Replace when damaged.

Belt pulley and clutch

Never start the engine when the belt pulley and clutch are removed for maintenance.

Carburettor

WARNING! Do not start the machine without

!the cutting arm or cutting head ???tted. Otherwise the clutch could come loose and cause personal injuries.

The carburettor is equipped with ???xed needles to ensure the machine always receives the correct mixture of fuel and air. When the engine lacks power or accelerates poorly, do the following:

???Check the air ???lter and replace if necessary.

???When this does not help, contact an authorised service workshop.

Adjusting the idle speed

Adjust the idle speed using the T screw. When an adjustment is necessary, ???rst turn the screw clockwise until the blade starts to rotate. Now turn the screw anti-clockwise until the blade stops rotating.

T

Rec. idle speed: 2700 rpm

WARNING! If the idle speed cannot be

!adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.

Fuel ???lter

???The fuel ???lter sits inside the fuel tank.

???The fuel tank must be protected from contamination when ???lling. This reduces the risk of operating disturbances caused by blockage of the fuel ???lter located inside the tank.

???The ???lter cannot be cleaned but must be replaced with a new ???lter when it is clogged. The ???lter should be changed at least once per year.

Air ???lter

Air ???lters must be regularly cleaned to remove dust and dirt in order to avoid:

???Carburettor malfunctions

???Starting problems

???Loss of engine power

???Unnecessary wear to engine parts.

???Excessive fuel consumption.

The air ???lter system consists of an oiled foam plastic ???lter (1) and a paper ???lter (2):

1The foam plastic ???lter is easily accessible under the ???lter cover A. This ???lter should be checked weekly and replaced if necessary.

A

B

In order to obtain a good ???ltering effect, the ???lter must be replaced regularly or cleaned and oiled. A special HUSQVARNA oil has been produced for this purpose.

Remove the foam plastic ???lter. Wash the ???lter well in tepid soapy water. After cleaning, rinse the ???lter well in clean water. Squeeze out and allow the ???lter to dry. NOTE! High pressure compressed air can damage the foam.

Put the ???lter in a plastic bag and pour the ???lter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the ???lter inside the plastic bag and pour off the excess before ???tting the ???lter to the machine. CAUTION! Never use common engine oil.

2The paper ???lter is accessible under cover B. This ???lter must be replaced/cleaned when the engine's power drops or each month. The ???lter is cleaned by shaking. Note that the ???lter must not be washed. NOTE! High pressure compressed air can damage the ???lter.

An air ???lter that has been in use for a long time cannot be cleaned completely. The ???lter must therefore be replaced with a new one at regular intervals. A damaged air ???lter must always be replaced.

IMPORTANT INFORMATION

Poor maintenance of the air ???lter will cause carbon build-up on the spark plug and abnormal wear to engine parts.

Starter

WARNING! When the recoil spring is wound

!up in the starter housing it is under tension and can, if handled carelessly, pop out and cause personal injury.

Always be careful when changing the recoil spring or the starter cord. Always wear protective goggles.

Changing a broken or worn starter cord

???Loosen the screws that hold the starter against the crankcase and remove the starter.

???Pull the cord out about 30 cm and lift it into the cut-out in the periphery of the starter pulley. When the cord is intact: Release the spring tension by letting the pulley rotate slowly backwards.

Remove any remnants of the old starter cord and check that the return spring works. Insert the new starter cord through the hole in the starter housing and in the cord pulley.

Secure the starter cord around the cord pulley as illustrated. Tighten the fastening well and ensure that the free end is as short as possible. Secure the end of the starter cord in the starter handle.

Guide the cord through the cut-out in the periphery of the pulley and wind the cord 3 times clockwise around the centre of the starter pulley.

Now pull the starter handle and in doing so tension the spring. Repeat the procedure once more, but this time with four turns.

Note that the starter handle is drawn to its correct home position after tensioning the spring.

Check that the spring is not drawn to its end position by pulling out the starter line fully. Slow the starter pulley with your thumb and check that you can turn the pulley at least a further half turn.

Tensioning the recoil spring

???Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise.

Changing a broken recoil spring

???Undo the bolt in the centre of the pulley and remove the pulley.

???Bear in mind that the return spring lies tensioned in the starter housing.

???Loosen the bolts holding the spring cassette.

???Remove the recoil spring by turning the starter over and loosen the hooks, with the help of a screwdriver. The hooks hold the return spring assembly on the starter.

???Lubricate the recoil spring with light oil. Fit the pulley and tension the recoil spring.

Fitting the starter

???To ???t the starter, ???rst pull out the starter cord and place the starter in position against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls.

???Tighten the screws.

Spark plug

The spark plug condition is in???uenced by:

???Wrong fuel mixture (too much oil).

???Dirty ???lters.

These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting dif???culties.

???If the machine is low on power, dif???cult to start or runs poorly at idle speed: always check the spark plug ???rst before taking other steps. If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm.

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

5

4

3

2

1

1Air intake on the starter.

2Air guide plate.

3Fins on the ???ywheel.

4Cooling ???ns on the cylinder.

5Cylinder cover

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.

Muf???er

The muf???er is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause ???re if directed against dry and combustible material.

Never use a machine with a defective muf???er.
