s safety equipment

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. See the ”What is what?” section to locate where this equipment is positioned on your machine.

Throttle lock

The throttle lock is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lock both move back to their original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting.

Stop switch

Use the stop switch to switch off the engine.

Cutting attachment guard

This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment.

IMPORTANT! Whenever you use a clearing saw, brushcutter or trimmer you must wear personal protective equipment that is approved by the authorities. Personal protective equipment does not eliminate the risk of accidents, but it can reduce the effects of an injury in the event of an accident. Ask your dealer for help when choosing protective equipment.

WARNING! Listen out for warning signals or shouts when you are wearing hearing protection. Always remove your hearing protection as soon as the engine stops.

WARNING! Never use a machine that has faulty safety equipment! Carry out the inspection, maintenance and service routines listed in this section.

WARNING! Never use a cutting attachment without an approved guard. See the chapter on Technical data. If an incorrect or faulty guard is ﬁtted this can cause serious personal injury.

SAFETY INSTRUCTIONS

Vibration damping system

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

Using incorrectly wound cord or a blunt or incorrect cutting attachment (wrong type or incorrectly ﬁled, see instructions under the heading Filing the blade) increases the level of vibration.

The machine

′

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

′

s handle unit.

Quick release

There is an easily accessible, quick release ﬁtted at the front as a safety precaution in case the engine catches ﬁre, or in any other situation that requires you to free yourself from the machine and harness. See instructions under the heading Adjusting the harness and clearing saw.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A mufﬂer ﬁtted with a catalytic converter is also designed to reduce harmful exhaust gases.

In countries that have a warm and dry climate there is a signiﬁcant risk of ﬁre. We therefore ﬁt certain mufﬂers with a spark arrestor mesh. Check whether the mufﬂer on your machine is ﬁtted with this kind of mesh.

For mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine. See instructions under the heading Checking, maintaining and servicing the machine’s safety equipment.

Cutting equipment

Saw blades are intended for cutting ﬁbrous types of wood.

Grass blades and grass cutters are intended for cutting coarse grass.

A trimmer head is intended for trimming grass.

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. The risk increases at low temperatures.

WARNING! Mufﬂers ﬁtted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of ﬁre!

WARNING! The inside of the mufﬂer contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged mufﬂer.

WARNING! Bear in mind that: Engine exhaust fumes contain carbon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated.

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!

SAFETY INSTRUCTIONS

Locking nut

• When ﬁtting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.)

• Tighten the nut using the socket spanner. 35-50 Nm (3.55 kpm).

Cutting equipment

Filing the saw blade

• See the cutting attachment packaging for correct sharpening instructions.

• A correctly ﬁled blade is essential for working efﬁciently and to avoid unnecessary wear to the blade and clearing saw.

• Make sure that the blade is well supported when you ﬁle it. Use a 5.5 mm round ﬁle with a ﬁle holder.

• The ﬁling angle is 15

. File alternate teeth to the right and those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a ﬂat ﬁle, in exceptional cases. If so, this should be done before ﬁling with a round ﬁle. The top edges must be ﬁled down by the same amount for all the teeth.

CAUTION! The nylon lining inside the locking nut must not

be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.

WARNING! Never use a machine with faulty safety equipment. The machine’s safety equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.

SAFETY INSTRUCTIONS

• Adjust the blade setting. This should be 1 mm.

Sharpening grass cutters and grass blades

• See the cutting attachment packaging for correct sharpening instructions.

• Sharpen blades and cutters using a single-cut ﬂat ﬁle.

• Sharpen all edges equally to maintain the balance of the blade.

Trimmer head

• Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data.

• Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared.

• The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.

• Make sure that the cutter on the trimmer guard is intact. This is used to cut the cord to the correct length.

• To increase the life of the cord it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.

General safety precautions

Starting

• The complete clutch cover and shaft must be ﬁtted before the machine is started, otherwise the clutch can come loose and cause personal injury.

• Never start the machine indoors. Exhaust fumes can be dangerous if inhaled.

• Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment.

• Place the machine on the ground, ensure the cutting attachment is clear of twigs and stones. Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot). Then grip the starter handle with your right hand and pull the starter cord.

IMPORTANT! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.

WARNING! Always stop the engine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it.

IMPORTANT!

The machine is only designed for trimming grass, grass clearing and/or forestry clearing.

The only accessories you can operate with this engine unit are the cutting attachments we recommend in the chapter on Technical data.

Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination.

Never use the machine in extreme weather conditions such as severe cold, very hot and/or humid climates.

General working instructions

Basic safety rules

1 Look around you:

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

- To ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment.

- CAUTION! Do not use the machine unless you are able to call for help in the event of an accident.

2 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 often brings added risks, such as icy ground, unpredictable felling direction, etc.

3 Make sure you can move and stand safely. Check the area

around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

4 Switch off the engine before moving to another area. Fit

the transport guard before carrying or transporting the equipment any distance.

5 Never put the machine down with the engine running

unless you have it in clear sight.

WARNING! Take care when handling fuel. Bear in mind the risk of ﬁre, explosion and inhaling fumes.

IMPORTANT!

This section describes the basic safety precautions for working with clearing saws and trimmers.

If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop.

Avoid all usage which you consider to be beyond your capability.

You must understand the difference between forestry clearing, grass clearing and grass trimming before use.

SAFETY INSTRUCTIONS

Adjusting the harness and clearing saw

Safety release

At the front is an easily accessible, quick release. Use this if the engine catches ﬁre or in any other emergency situation that requires you to free yourself from the machine and harness.

Spreading the load on your shoulders

A well-adjusted harness and machine makes work much easier. Adjust the harness for the best working position. Tension the side straps so that the weight is evenly distributed across both shoulders.

Correct height

Adjust the shoulder strap so that the cutting attachment is parallel to the ground.

Correct balance

Let the cutting attachment rest lightly on the ground. If you use a saw blade it should balance about 10 cm above the ground to prevent contact with stones and the like. Adjust the position of the support hook to balance the clearing saw correctly.

Basic working techniques

• Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage.

Terms

• Use a saw blade for cutting woody growth with thin stems.

• Use a grass cutter or grass blade for clearing grass.

• Use a trimmer head or plastic blades for lighter clearing work, for example along verges or around trees.

WARNING! When using a clearing saw it must always be hooked securely to the harness. Otherwise you will be unable to control the clearing saw safely and this can result in injury to yourself or others. Never use a harness with a defective quick release. Always use a double harness that distributes the load across both shoulders.

WARNING! Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.

12 – English

SAFETY INSTRUCTIONS

The ABC of clearing

Always use the correct equipment.

Make sure the equipment is well adjusted.

Follow the safety precautions.

Organise your work carefully.

Always use full throttle when starting to cut with the blade.

Always use sharp blades.

Avoid stones.

Working methods

• Before you start clearing, check the clearing area, the type of terrain, the slope of the ground, whether there are stones, hollows etc.

• On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it.

• The strip should be planned so that you avoid going over ditches or other obstacles on the ground.

Brush cutting with a saw blade

• Cut through thin stems and brush. Work with a sawing movement, swinging sideways.

• Avoid cutting with the area of the blade between the 12 o’clock and 3 o’clock positions.

Grass clearing using a grass blade

• Grass blades and grass cutters must not be used on woody stems.

• A grass blade is used for all types of tall or coarse grass.

• The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-to-right is the return stroke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting.

• If the blade is angled to the left when clearing grass, the grass will collect in a line, which makes it easier to collect, e.g. by raking.

• Try to work rhythmically. Stand ﬁrmly with your feet apart. Move forward after the return stroke and stand ﬁrmly again.

• Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground.

• Reduce the risk of material wrapping around the blade by following these instructions:

1 Always work at full throttle.

2 Avoid the previously cut material during the return

stroke.

• Stop the engine, unclip the harness and place the machine on the ground before you start to collect the cut material.

WARNING! Avoid cutting with the area of the blade between the 12 o’clock and 3 o’clock positions. Because of the speed of rotation of the blade kickback can occur if you attempt to cut thick stems with this area of the blade.

WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the blade is rotating, as this can result in serious injury.

Stop the engine and blade before you remove material that has wound around the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burnt if you touch it.

WARNING! Watch out for thrown objects. Always wear eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury.

Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. Stop the machine immediately if anyone approaches. Never swing the machine around without ﬁrst checking behind you to make sure no-one is within the safety zone.

SAFETY INSTRUCTIONS

Grass trimming with a trimmer head

Trimming

• Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut.

• The cord can easily remove grass and weeds up against walls, fences, trees and borders, however it can also damage sensitive bark on trees and bushes, and damage fence posts.

• Reduce the risk of damaging plants by shortening the cord to 10-12 cm and reducing the engine speed.

Clearing

• The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. CAUTION! This technique increases the wear on the cord.

• The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences.

• When trimming and clearing you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head.

Cutting

• The trimmer is ideal for cutting grass that is difﬁcult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool.

• Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.

Sweeping

• The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro.

• When cutting and sweeping you should use full throttle to obtain the best results.

WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the blade is rotating, as this can result in serious injury.

Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. Stop the machine immediately if anyone approaches.

FUEL HANDLING

Fuel

CAUTION! 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

CAUTION! Always use high grade unleaded oil mixed gasoline (minimum 87 RON). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Leaded petrol will destroy the catalytic converter and it will no longer serve its purpose.

Use low-emission gasoline, also known as alkylate gasoline, if it is available.

• This engine is certiﬁed to operate on unleaded gasoline.

• The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 so-called “knocking“ can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown.

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

Two-stroke oil

• For the best results and performance use JONSERED two-stroke oil, which is specially formulated for our twostroke engines. Mixture 1:50 (2%).

• Never use two-stroke oil intended for water-cooled outboard engines, sometimes referred to as outboard oil.

• Never use oil intended for four-stroke engines.

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.

• If the machine is not used for some time the fuel tank

should be emptied and cleaned.

• This engine is certiﬁed to operate on unleaded gasoline.

WARNING! Always ensure there is adequate ventilation when handling fuel.

FUEL HANDLING

Fuelling

• Clean the area around the fuel cap. Contamination in the tank can cause operating problems.

• Ensure that the fuel is well mixed by shaking the container before ﬁlling the tank.

WARNING! Taking the following precautions, will lessen the risk of ﬁre:

Do not smoke or place hot objects near fuel.

Always shut off the engine before refuelling. Always stop the engine and let it cool for a few minutes 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.

STARTING AND STOPPING

Check before starting

For safety reasons follow these recommendations!

• Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found.

• Check that the support ﬂange is not cracked due to fatigue or due to being tightened too much. Discard the support

ﬂange if it is cracked.

• Ensure the locking nut has not lost its captive force. The

nut lock should have a locking force of at least 1.5 Nm. The tightening torque of the locking nut should be 35-50 Nm.

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

• Check that the trimmer head and trimmer guard are not damaged or cracked. Replace the trimmer head or trimmer guard if they have been exposed to impact or are cracked.

• Never use the machine without a guard nor with a defective guard.

• All covers must be correctly ﬁtted and undamaged before you start the machine.

Starting and stopping

Cold engine

Ignition: Set the stop switch to the start position.

MAINTENANCE

Carburettor

Your Jonsered product has been designed and manufactured to speciﬁcations that reduce harmful exhaust fumes. The engine will be run in after it has used 8-10 tanks of fuel. To ensure that the engine runs at peak performance and produces as little harmful exhaust fumes as possible after the running-in period, ask your dealer/service workshop (which has a rev counter for this purpose) to adjust your carburettor.

Function

• The carburettor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburettor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine.

• The setting of the carburetor means that the engine is adepted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil.

• The carburettor has three adjustment controls:

L = Low speed jet

H = High speed jet

T = Idle adjustment screw

• The L and H-jets are used to adjust the supply of fuel to match the rate that air is admitted, which is controlled with the throttle. If they are screwed clockwise the air/fuel ratio becomes leaner (less fuel) and if they are turned anticlockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed.

• The T-screw regulates the throttle setting at idle speed. If the T-screw is turned clockwise this gives a higher idle speed; turning it anti-clockwise gives a lower idle speed.

Basic setting

• The basic carburettor settings are adjusted during testing at the factory. The basic setting is richer than the optimal setting and should be maintained for the ﬁrst few hours the machine is in use. The carburettor should then be ﬁnely adjusted. Fine adjustment should be carried out by a skilled technician.

CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned anticlockwise until the cutting attachment stops.

Rec. idle speed 2700 rpm

Recommended max. speed: See the Technical data section.

Fine adjustment

• When the machine has been ”run-in” the carburettor

should be ﬁnely adjusted. The ﬁne adjustment should be carried out by a qualiﬁed person. First adjust the Ljet, then the idling screw T and then the H-jet.

Conditions

• Before any adjustments are made, make sure that the air ﬁlter is clean and the air ﬁlter cover is ﬁtted. If you adjust

the carburettor when the air ﬁlter is dirty it will result in a leaner mixture when the ﬁlter is ﬁnally cleaned. This can lead to serious engine damage.

• Carefully turn both jets, L and H, so that they are midway between fully screwed in and fully screwed out.

• Do not attempt to adjust the L and H jets beyond either stop as this could cause damage.

• Now start the machine according to the starting instructions and let it warm up for 10 minutes.

CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned anticlockwise until the cutting attachment stops.

Low speed jet L

• Try to ﬁnd the highest idling speed, turning the low speed needle L clockwise respectively counter-clockwise. When the highest speed has been found, turn the low speed needle L 1/4 turn counter-clockwise.

CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned anticlockwise until the cutting attachment stops.

Fine adjustment of the idle speed T

Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the idle adjustment screw T clockwise until the cutting attachment starts to rotate. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine

WARNING! The complete clutch cover and shaft must be ﬁtted before the machine is started, otherwise the clutch can come loose and cause personal injury.

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.

+ 1/4

English – 23

MAINTENANCE

will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.

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.

High speed jet H

Note that the engine should not be under load when you adjust the high speed jet H. You should therefore remove the cutting attachment, nut, support ﬂange and drive disc before adjusting the high speed jet H. The high speed jet H affects the engine power, speed, temperature and fuel consumption. If the high speed jet H is set too lean (screwed in too far) the engine speed will be too high and cause engine damage. Do not let the engine run at full speed for more than 10 seconds.

Apply full throttle and turn the high speed jet H very slowly clockwise until the engine slows down. Then turn the high speed jet H very slowly anticlockwise until the engine starts to run unevenly. Now turn the high speed jet H slowly clockwise a little way until the engine runs smoothly.

The high speed jet H is adjusted correctly when the machine burbles a little. If the machine races then the setting is too lean. If the engine produces a lot of smoke and burbles a lot then the setting is too rich.

CAUTION! For optimum adjustment of the carburettor, contact a qualiﬁed dealer/service workshop that has a revolution counter at their disposal.

Correctly adjusted carburettor

When the carburettor is correctly adjusted the machine will accelerate without hesitation and burble a little at maximum speed. It is also important that the cutting attachment does not rotate at idle. If the low speed jet L is set too lean it may cause starting difﬁculties and poor acceleration.

If the high speed jet H is set too lean it will result in less power, less performance, poor acceleration and/or damage to the engine. If both the L and H jets are set too rich it will results in acceleration problems or too low a working speed.

Adjusting the start throttle speed

The correct start throttle speed is set by means of an adjuster on the rear of the handle next to the cable. Use this screw (4 mm Allen screw) to increase or decrease the start throttle speed.

Proceed as follows:

1 Run the machine at idle.

2 Press the start throttle lock as described under the

heading Starting and stopping.

3 If the start throttle speed is too low (below 4000 rpm), turn

the adjuster screw A clockwise until the cutting attachment starts to rotate. Then turn A clockwise a further 1/2 turn.

4 If the start throttle speed is too high, turn the adjuster

screw A anticlockwise until the cutting attachment stops. Then turn adjuster screw A clockwise a further 1/2 turn.

Mufﬂer

CAUTION! Some mufﬂers are ﬁtted with a catalytic converter.

See chapter on Technical data to see whether your machine is ﬁtted with a catalytic converter.

The mufﬂer 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 ﬁre if directed against dry and combustible material.

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.

5 mm

24 – English

MAINTENANCE

Some mufﬂers are equipped with a special spark arrestor mesh. If your machine has this type of mufﬂer, you should clean the mesh at least once a week. This is best done with a wire brush.

On mufﬂers without a catalytic converter the mesh should be cleaned weekly, or replaced if necessary. On mufﬂers ﬁtted with a catalytic converter the mesh should be checked, and if necessary cleaned, monthly. If the mesh is damaged it

should be replaced.

If the mesh is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the mufﬂer. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston.

CAUTION! Never use a machine with a defective mufﬂer.

Cooling system

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

The cooling system consists of:

1 Air intake on the starter.

2 Fins on the ﬂywheel.

3 Cooling ﬁns on the cylinder.

4 Cylinder cover (directs cold air over the cylinder).

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.

Bevel gear

The bevel gear is ﬁlled with the right amount of grease at the factory. However, before using the machine you should check that the bevel gear is ﬁlled 3/4 full with grease. Use JONSERED special grease.

The grease in the bevel gear does not normally need to be changed except if repairs are carried out.

Air ﬁlter

The air ﬁlter 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.

Clean the ﬁlter every 25 hours, or more regularly if conditions are exceptionally dusty.

Cleaning the air ﬁlter

Remove the air ﬁlter cover and take out the ﬁlter. Wash it clean in warm, soapy water. Ensure that the ﬁlter is dry before reﬁtting it.

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

always be replaced.

If the machine is used in dusty conditions the air ﬁlter should be soaked in oil. See instructions under the heading Oiling the air ﬁlter.

Oiling the air ﬁlter

Always use special ﬁlter oil. Filter oil contains a solvent to make it spread evenly through the ﬁlter. You should therefore avoid skin contact.

English – 25

MAINTENANCE

Put the ﬁlter in a plastic bag and pour the ﬁlter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the ﬁlter inside the plastic bag and pour off the excess before ﬁtting the ﬁlter to the machine. Never use common engine oil. This would drain through the ﬁlter quite quickly and collect in the bottom.

Spark plug

The spark plug condition is inﬂuenced by:

• Incorrect carburettor adjustment.

• An incorrect fuel mixture (too much or incorrect type of

oil).

• A dirty air ﬁlter.

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

If the machine is low on power, difﬁcult to start or runs poorly at idle speed: always check the spark plug ﬁrst before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.5 mm (0,020"). The spark plug should be replaced after about a month in operation or earlier if necessary.

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

Sharpening grass cutters and grass blades

• See the cutting attachment packaging for correct sharpening instructions.

• Sharpen blades and cutters using a single-cut ﬂat ﬁle.

• Sharpen all edges equally to maintain the balance of the

blade.

Filing the saw blade

• See the cutting attachment packaging for correct sharpening instructions.

• A correctly ﬁled blade is essential for working efﬁciently and to avoid unnecessary wear to the blade and clearing saw.

• Make sure that the blade is well supported when you ﬁle it. Use a 5.5 mm round ﬁle with a ﬁle holder.

• The ﬁling angle is 15°. File alternate teeth to the right and

those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a ﬂat ﬁle, in exceptional cases. If so, this should be done before ﬁling with a round ﬁle. The top edges must be ﬁled down by the same amount for all the teeth.

• Adjust the blade setting. This should be 1 mm.

WARNING! Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the speciﬁed type.

WARNING! Using an incorrect cutting attachment or an incorrectly sharpened blade increases the risk of kickback.
