MACHINE´S SAFETY EQUIPMENT

• Start the power cutter and apply full throttle. Release the throttle control and check that the cutting blade stops and remains stationary. If the cutting blade rotates when the throttle is in the idle position you should check the carburettor’s idle adjustment. See instructions in the section "Maintenance".

!

WARNING! Never use a machine that has faulty safety equipment! If your machine fails any of these checks contact your service agent to get it repaired.

The engine should be switched off, and the stop switch in STOP position.

This section describes the machine

′s safety equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly.

Throttle lockout

The throttle trigger lock is designed to prevent accidental operation of the throttle. When the lock (A) is pressed in this releases the throttle (B).

Stop switch

Use the stop switch to switch off the engine.

The trigger lock remains pressed in as long as the throttle is pressed. When the grip on the handle is released the throttle trigger and the throttle trigger lock both return to their original positions. This is controlled by two independent return spring systems. This means that the throttle trigger is automatically locked in the idle position.

Checking the throttle lockout

• Make sure the throttle control is locked at the idle setting when the throttle lockout is released.

Checking the stop switch

• Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

• Press the throttle lockout and make sure it returns to its original position when you release it.

Blade guard

!

WARNING! Always check that the guard is correctly fitted before starting the machine.

This guard is fitted above the cutting blade and is designed to prevent parts of the blade or cutting fragments from being thrown towards the user.

• Check that the throttle trigger and throttle lockout move freely and that the return springs work properly.

Checking the blade guard

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

• Check that the cutting blade is fitted correctly and does not show signs of damage. A damaged cutting blade can cause personal injury.

MACHINE´S SAFETY EQUIPMENT

Vibration damping system

Inspecting the muffler

Check regularly that the muffler is complete and secured correctly.

!

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.

Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the fingers, hands or wrists. These symptoms may be increased in cold temperatures.

• Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.

• The machine

′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine

′s handle unit. The engine body, including the cutting equipment, is insulated from the handles by vibration damping units.

Checking the vibration damping system

!

WARNING! The engine should be switched off, and the stop switch in STOP position.

• Check the vibration damping units regularly for cracks or deformation. Replace them if damaged.

• Check that the vibration damping element is securely attached between the engine unit and handle unit.

Muffler

!

WARNING! Never use a machine without a muffler, or with a faulty muffler. A damaged muffler may substantially increase the noise level and the fire hazard. Keep fire fighting equipment handy.

The muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours.

The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

CUTTING BLADES

Hand-held, high-speed machines

WARNING! A cutting blade may burst and cause injury to the operator.

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

!

WARNING! Never use a cutting blade at a lower speed rating than that of the power cutter. Only use cutting blades intended for high speed handheld power cutters.

• Our cutting blades are manufactured for high-speed, portable power cutters.

• 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.

• 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.

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

Cutting blades for different materials

!

WARNING! Never use a cutting blade for any other purpose than that it was intended for.

Cutting plastics with a diamond blade can cause kickback when the material melts due to the heat produced when cutting and sticks to the blade. Never cut plastic materials with a diamond blade!

Cutting in metal generates sparks that may cause fire. Do not use the machine near to ignitable substances or gases.

Follow the instructions supplied with the cutting blade concerning the suitability of the blade for various applications, or consult your dealer in case of doubts.

* CAUTION! Only specialty blades.

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.

Abrasive blades

!

WARNING! Do not use abrasive blades with water. The strength is impaired when abrasive blades are exposed to water or moisture, which results in an increased risk of the blade breaking.

• The cutting material on abrasive blades consists of grit bonded using an organic binder. ”Reinforced blades” are made up of a fabric or fibre 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.

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

General

!

CUTTING BLADES

WARNING! Cutting plastics with a diamond blade can cause kickback when the material melts due to the heat produced when cutting and sticks to the blade.

Diamond blades get very hot when used. An overheated blade is a result of improper use, and may cause deformation of the blade, resulting in damage and injuries.

Cutting in metal generates sparks that may cause fire. Do not use the machine near to ignitable substances or gases.

• Diamond blades consist of a steel core 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.

Diamond blades for different materials

• Diamond blades are ideal for masonry, reinforced concrete and other composite materials.

• Diamond blades are available in several hardness classes.

• Special blades should be used when cutting metal. Ask your dealer for help in choosing the right product.

Sharpening diamond blades

• Always use a sharp diamond blade.

• 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.

Diamond blades for dry cutting

• Diamond blades for dry cutting can be used both with and without water cooling.

• When dry cutting, lift the blade out from the cut every 30–

60 seconds and let it rotate in the air for 10 seconds to let it cool. If this is not done, the blade may be overheated.

Diamond blades for wet cutting

• Diamond blades for wet cutting must be water cooled. If this is not done, the blade may be overheated.

• Water cooling cools the blade and increases its service life while also reducing the formation of dust.

Toothed blades, carbide tipped blades and emergency situations

Government regulation requires a different type of guarding for carbide tipped blades not available on power cutters – a so called 360 degree guard. Power Cutters (this saw) use

Abrasive or Diamond blades and have a different guarding system which does not provide protection against the dangers presented by wood cutting blades.

Use of this power cutter with a carbide tipped blade is a violation of OSHA regulations.

Due to the hazardous nature and exigent circumstances involved with fire fighting and rescue operations conducted by the various highly trained public safety forces, safety professionals (fire departments), Husqvarna is aware that they may use this power cutter with carbide tipped blades in certain emergency situations due to the ability of carbide tipped blades to cut many different types of obstructions and materials in combination without having to take time to switch blades or machines. When using this power cutter be aware at all times that carbide tipped blades are more kickback prone than abrasive or diamond blades if not used properly.

Carbide tipped blades can also throw pieces of material away from the blade.

For these reasons, a power cutter equipped with a carbide tipped blade should never be used except by highly trained public safety professionals who are aware of the risks associated with its use and then only in those exigent circumstances when other tools are deemed inefficient and ineffective to for fire or rescue operations. A power cutter equipped with carbide tipped blade should never be used to cut wood in non-rescue operations.

ASSEMBLING AND ADJUSTMENTS

WARNING! The engine should be switched off, and the stop switch in STOP position.

Husqvarna’s blades are approved for hand-held power cutters.

Checking the drive shaft and flange washers

When the blade is replaced with a new one, check the flange washers and the drive shaft.

• Check that the threads on the drive shaft are undamaged.

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

Checking the direction of the blade rotation

• When using diamond blades make sure that it rotates in the direction indicated by the arrow on the blade. The direction of rotation for the machine is shown by arrows on the cutting arm.

Fitting the cutting blade

• The blade is placed on the bushing (A) between the inner flange washer (B) and the flange washer (C). The flange washer is turned so that it fits on the axle.

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

Checking the bushing

Bushings are used to fit the machine to the centre hole in the cutting blade. The machine is supplied with two different sized bushings, 20 mm (25/32’’) and 25, 4 mm (1’’). A plate on the blade guard indicates which bushing has been factory-fitted.

• Lock the shaft. Insert a tool in the hole in the cutting head and rotate the blade until it is locked.

When replacing the bushing, the labeling of the machine must be updated with the supplied decal.

• Check that the bushing on the machine's spindle shaft corresponds with the centre hole of the cutting blade. The blades are marked with the diameter of the centre hole.

• Tightening torque for the bolt holding the blade is: 15-25

Nm (130-215 in.lb).

Blade guard

The guard for the cutting equipment should be adjusted so that the rear section is flush 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.

The blade guard is friction locked.

• Press the ends of the guard against the work piece or adjust the guard with the adjustment handle. The guard must always be fitted on the machine.

English

– 11

ASSEMBLING AND ADJUSTMENTS

Reversible cutting head

The machine is fitted with a reversible cutting head allowing cutting close to a wall or at ground level, restricted only by the thickness of the blade guard.

There is an increased risk for kickback when cutting with the cutting head reversed. The cutting blade is further away for the centre of the machine which means the handle and the cutting blade are no longer in alignment. It is more difficult to restrain the machine if the blade gets jammed or stuck in its kickback danger zone. See under the "Kickback" heading in the "Operating" section for additional information.

Some of the machine's good ergonomic features may also be jeopardised. Cutting with the cutting head reversed should only occur with cuts that are not possible in a standard manner.

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

• Now unscrew the bolts and dismantle the belt guard.

• Disconnect the water hose from the blade guard.

• Remove the belt from the belt pulley.

• The cutting head is now loose and can be removed from the machine.

• Remove the cutting head and attach it to the other side of the cutting arm.

• Fit the belt guard to the reversed cutting head.

• Tighten the drive belt. See instructions in the section

"Maintenance".

• A longer water hose has to be fitted to the machine if wet cutting is carried out.

Fuel

WARNING! Running an engine in a confined or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning. Use fans to ensure proper air circulation when working in trenches or ditches deeper than one meter (3 foot).

Fuel and fuel fumes are highly inflammable and can cause serious injury when inhaled or allowed to come in contact with the skin.

For this reason observe caution when handling fuel and make sure there is adequate ventilation.

The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material!

Do not smoke and do not place any hot objects in the vicinity of fuel.

NOTICE! The machine is equipped with a two-stroke engine and must always been run using a mixture of gasoline 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.

Gasoline

• Use good quality unleaded gasoline.

• The lowest recommended octane grade is 87

((RON+MON)/2). If you run the engine on a lower octane grade than 87 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage.

• When working at continuous high revs a higher octane rating is recommended.

Environment fuel

The use of environmentl fuel (alkylate fuel), or environment fuel for four-stroke engines blended with two-stroke oil as set out below is recommended.

Ethanol blended fuel, E10 may be used (max 10% ethanol blend). Using ethanol blends higher than E10 will create lean running condition which can cause engine damage.

Two-stroke oil

• For best results and performance use HUSQVARNA twostroke engine oil, which is specially formulated for our aircooled 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.

FUEL HANDLING

Mixing

• Always mix the gasoline and oil in a clean container intended for fuel.

• Always start by filling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline.

• Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank.

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

Do not start cutting until the working area is clear and you are standing firmly.

• Observe your surroundings to ensure that nothing can affect your control of the machine.

• Ensure that no one/nothing can come into contact with the cutting equipment or be hit by parts if the blade breaks.

• Do not use the machine in bad weather, such as dense fog, heavy 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 firm 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.

• Ensure that the working area is sufficiently illuminated to create a safe working environment.

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

!

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

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.

Cutting plastics with a diamond blade can cause kickback when the material melts due to the heat produced when cutting and sticks to the blade. Never cut plastic materials with a diamond blade!

Cutting in metal generates sparks that may cause fire. Do not use the machine near to ignitable substances or gases.

• The machine is designed and intended for cutting with abrasive blades or diamond blades intended for high speed handheld machines. The machine shall not be used with any other type of blade, or for any other type of cutting.

• Check that the cutting blade is fitted correctly and does not show signs of damage. See the instructions in the sections "Cutting blades" and "Assembly and settings".

• Never cut asbestos materials!

• Maintain a safe distance from the cutting blade when the engine is running.

• Never move the machine when the cutting equipment is rotating. The machine is equipped with a friction retarder to shorten the stop time.

• The guard for the cutting equipment should be adjusted so that the rear section is flush 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. The guards for the cutting equipment must always be fitted when the machine is running.

• Never use the kickback zone of the blade for cutting. See instructions under the heading "Kickback".

• Keep a good balance and a firm foothold.

16 –

English

OPERATING

• Never cut above shoulder height. Never cut from a ladder.

Use a platform or scaffold when working at high altitude.

Cutting with toothed/carbide tipped blades during rescue operaions

• Always hold the machine in a firm grip with both hands.

Hold it so that the thumbs and fingers grip round the handles.

• Stand at a comfortable distance from the work piece.

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

• Apply the cutting blade gently with high rotating speed (full throttle) Maintain full speed until cutting is complete.

• Let the machine work without forcing or pressing the blade.

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

!

WARNING! A power cutter should never be used with carbide tipped blade for nonemergency work, such as in the construction trades.

Be aware at all times that carbide tipped blades are more kickback prone than abrasive or diamond blades if not used properly.

If the public safety force (fire department) that purchased this power cutter has decided to equip this unit with a carbide tipped blade for rescue operations, the following safety considerations must be adhered to.

Training and protective equipment

• Only operators trained in the use of cutting with a power cutter equipped with carbide tipped blade shall be allowed to operate the power cutter.

• Full protective fire fighting gear shall be worn by the operator at all times.

• A full face shield (not just protective eye glasses) shall be worn by the operator to protect the face from flying debris or a sudden kick-back of the power cutter.

Risk area

No persons that do not have the protective equipment described above shall be allowed inside the risk area for thrown material.

• 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.

20 m (66 ft)

Blade speed

Apply the cutting blade gently with high rotating speed (full throttle) Maintain full speed until cutting is complete. Low blade speed, especially in hard and thin materials can result in jamming and the breaking-off of the carbide tips.

Thin material

Cutting thin and hard material (i.e. a sheet metal covered roof) should be conducted in a forward direction for best control.

English

– 17

OPERATING

Pinching or jamming

Make a careful evaluation of how the object will move during the final stage of the cutting to avoid pinching or jamming. The cut must open during the cut. If the object sags and the cut begins to close the blade may pinch, possibly resulting in a kick-back or damage to the blade.

Reactive force

A reactive force is always present when cutting. The force pulls the machine in the opposite direction to the blade rotation. Most of the time this force is insignificant. If the blade is pinched or stalled the reactive force will be strong and you might not be able to control the power cutter.

Cutting in line

Skewing or twisting in the line of cut will reduce cutting efficiency and damage the blade.

Kickback zone

Never use the kickback zone of the blade for cutting. If the blade is pinched or stalled in the kickback zone, the reactive force will push the power cutter up and back towards the user in a rotating motion causing serious or even fatal injury.

Before each rescue operation

Check that the blade and th blade guard is not damaged or cracked. Replace the blade or the blade guard if it is exposed to impact or is cracked.

• Check that no carbide tips have loosened from the cutting blade.

• Check that the blade is not skew or shows signs of cracking or other defects.

When cutting in hard materials carbide tipped blades will rapidly lose its sharpness. For best performance during rescue operations we recommend that a new blade be installed.

Kickback

!

WARNING! Kickbacks are sudden and can be very violent. The power cutter can be thrown up and back towards the user in a rotating motion causing serious or even fatal injury. It is vital to understand what causes kickback and how to avoid it before using the machine.

Kickback is the sudden upward motion that can occur if the blade is pinched or stalled in the kickback zone. Most kickbacks are small and pose little danger. However a kickback can also be very violent and throw the power cutter up and back towards the user in a rotating motion causing serious or even fatal injury.

Climbing kickback

If the kickback zone is used for cutting the reactive force drives the blade to climb up in the cut. Do not use the kickback zone. Use the lower quadrant of the blade to avoid climbing kickback.

Pinching kickback

Pinching is when the cut closes and pinches the blade. If the blade is pinched or stalled the reactive force will be strong and you might not be able to control the power cutter.

If the blade is pinched or stalled in the kickback zone, the reactive force will push the power cutter up and back towards the user in a rotating motion causing serious or even fatal injury.

OPERATING

Pipe cutting and pinching

Special care should be taken whet cutting in pipes. If the pipe is not properly supported and the cut kept open through out the cut the blade might be pinched in the kickback zone and cause a severe kickback.

How to aviod kickback

Avoiding kickback is simple.

• The work piece must always be supported so that the cut stays open when cutting through. When the cut opens there is no kickback. If the cut closes and pinches the blade ther is always a risk of kickback.

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

• 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.

Transport and storage

• Secure the equipment during transportation in order to avoid transport damage and accidents.

• For transport and storage of cutting blades, see the section "Cutting blades".

• For transport and storage of fuel, see the section "Fuel handling".

• Store the equipment in a lockable area so that it is out of reach of children and unauthorized persons.

MAINTENANCE

Cleaning

External cleaning

• Clean the machine daily by rinsing it with clean water after the work is finished.

Cooling air intake

• Clean the cooling air intake when needed.

Drive belt

Check the tension of the drive belt

• For correct tensioning of the drive belt, the square nut should be positioned opposite the marking on the belt cover.

NOTICE! A dirty or blocked air intake results in the machine overheating which causes damage to the piston and cylinder.

Spark plug

• If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking other steps.

• Ensure that the spark plug cap and ignition lead are undamaged to avoid the risk of electric shock.

• If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. Replace if necessary.

Tensioning the drive belt

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

• When the machine is equipped with a friction retarder, a scraping sound can be heard from the bearing housing when the blade is turned by hand. This is quite normal.

Please contact an accredited Husqvarna workshop if you have any questions.

• The drive belt is 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.

NOTICE! Always use the recommended spark plug type!

Use of the wrong spark plug can damage the piston/ cylinder.

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

• An incorrect fuel mixture (too much or incorrect type of oil).

• A dirty air filter.

Functional inspection

General inspection

• Check that nuts and screws are tight.

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

WARNING! Never start the engine when the belt pulley and clutch are removed for maintenance. Do not start the machine without the cutting arm or cutting head fitted. Otherwise the clutch could come loose and cause personal injuries.

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

!

CAUTION! 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.

• Start the engine and check the idling setting. When the carburettor is set correctly the cutting blade should be still while engine is idling.

• Adjust the idle speed using the T screw. When an adjustment is necessary, first turn the screw clockwise until the blade starts to rotate. Now turn the screw anticlockwise until the blade stops rotating.

T

• 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.

Rec. idle speed: 2700 rpm

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.

Checking the starter cord

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

• Replace the drive belt.

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

Carburetor

The carburettor is equipped with fixed 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 filter and replace if necessary. When this does not help, contact an authorised service workshop.

• 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.

English

MAINTENANCE

Changing a broken or worn starter cord

• 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.

• 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.

• 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.

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

Fitting the starter

• To fit the starter, first 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.

Tensioning the recoil spring

• 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.

Changing a broken recoil spring

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

• Tighten the screws.

Fuel system

General

• Check that the fuel cap and its seal are not damaged.

• Check the fuel hose. Replace when damaged.

Fuel filter

• The fuel filter sits inside the fuel tank.

• The fuel tank must be protected from contamination when filling. This reduces the risk of operating disturbances caused by blockage of the fuel filter located inside the tank.

• The filter cannot be cleaned but must be replaced with a new filter when it is clogged. The filter should be

changed at least once per year.

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

• Loosen the bolts holding the spring cassette.

Exposure to excessive amount of such dust can cause:

Respiratory disease (affecting your ability to breath), including chronic bronchitis, silicosis and pulmonary fibrosis from exposure to silica. These diseases may be fatal;

Skin irritation and rash.

Cancer according to NTP* and IARC*

*/ National Toxicology Program, International

Agency for Resaearch on Cancer

Take precautionary steps:

Avoid inhalation of and skin contact with dust, mist and fumes.

Wear and ensure that all bystanders wear appropriate respiratory protection such as dust masks designed to filter out microscopic particles. (See OSHA 29 CFR

Part 1910.1200)
