WARNING! Long-term inhalation of the engine's exhaust fumes can represent a health hazard.

A lawn mower is only designed to mow lawns. The only accessories you can use with this engine unit are the cutters we recommend in the Technical data chapter.

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 start a lawn mower unless the cutters and all covers are fitted correctly.

Never start the machine indoors. Exhaust fumes can be dangerous if inhaled. Keep in mind that the operator is responsible for accidents or hazards occuring to other people or their property.

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

Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment. The operator is responsible for any unsafe situations or risks that people and property are exposed to.

Place the lawn mower on firm, flat surface and start it. Make sure that the cutter cannot come into contact with the ground or other objects.

Never twist the starter cord around your hand.

WARNING! Running an engine in a confined or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning.

You must use personal protection whenever you use the machine. See the instructions under the heading Personal protection.

Never use a machine that has been modified in any way from its original specification.

Never use any accessories other than those recommended in this manual. See instructions under the headings Cutting equipment and Technical data.

WARNING! A faulty cutting attachment may increase the risk of accidents. See the instructions under the heading Start and stop. 80 – English SAFETY INSTRUCTIONS Fuel safety General working instructions (Refuelling/Storage.)

WARNING! Fuel and fuel vapour are highly inflammable. Take care when handling fuel and engine oil. Bear in mind the risk of fire, explosion and inhaling fumes.

Never refuel the machine while the engine is running.

Always ensure there is adequate ventilation when refuelling and filling oil.

Move the machine at least 3 m from the refuelling point before starting it. WARNING! This section describes basic safety precautions for working with the lawn mower. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsure about how to progress, stop and seek expert advice. Contact your dealer, service agent or an experienced lawn mower user. Avoid all usage which you consider to be beyond your capability 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 might come into contact with the cutting equipment.

Branches, twigs, stones, etc. should be removed from the lawn before you start to mow. Make sure the cutter does not hit foreign objects such as stones, roots or the like. This can make the cutter dull and bend the engine shaft.

Never lift up the lawn mower or carry it around when the engine is running. If you must lift the lawn mower, first switch off the engine and disconnect the ignition lead from the spark plug.

The fuel and engine oil tanks should be emptied before longer periods of storage or when transporting the lawn mower. Ask where you can dispose of surplus fuel and engine oil at your local petrol station. 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.

Always store the lawn mower and fuel so that any leakage or vapours do not risk coming into contact with sparks or naked flames. For example, electrical machines, electric motors, relays/switches, boilers, or the like. 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.

The lawn mower should not be used on inclines greater than 30 degrees.

The engine should be switched off when moving over ground that is not to be mowed. For example, gravel paths, stone, shingle, asphalt, etc. Never start the machine:

If you have spilt fuel or engine oil on the machine. Wipe off the spill and allow the remaining fuel to evaporate.

If you spill fuel or engine oil on yourself or your clothes. Change your clothes.

If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines. Transport and storage

Always store fuel in an approved container designed for that purpose. The brake handle must never be permanently anchored in handle when the machine is running. Follow the instructions above, but do not use a lawn mower in a situation where you cannot call for help in case of an accident. English – 81 SAFETY INSTRUCTIONS Basic mowing technique

WARNING! Make sure that your hands and feet do not come near the cutting attachment when the engine is running. Cutting height Shut down the engine before changing the cutting height. The cutting height can be adjusted in five different steps, mm. General

Mowing slopes can be dangerous. Do not use the lawn mower on very steep slopes.

The lawn mower should not be used on inclines greater than 30 degrees.

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.

Branches, twigs, stones, etc. should be removed from the lawn before you start to mow.

Never lift up the lawn mower or carry it around when the engine is running. If you must lift the lawn mower, first switch off the engine and disconnect the ignition lead from the spark plug.

Make sure the cutter does not hit foreign objects such as stones, roots or the like. This can make the cutter dull and bend the engine shaft. A bent axle gives imbalance and heavy vibration, which results in a great risk of the cutter becoming loose.

If any foreign object is hit or if vibrations occur stop the machine immediately. Disconnect the HT lead from the spark plug. Check that the machine is not damaged. Repair any damage.

Never mow more than 1/3 of the length of the grass. This especially applies during dry periods. Mow first with the cutting height set high. Then check the result and lower to an appropriate height. If the grass is really long, drive slowly and mow twice if necessary.

Do not set the cutting height too low as there is a risk that the cutters might hit slopes with unevenness. Adjusting the cutting height Shut down the engine before changing the cutting height. Set the cutting height using the cutting height control on the right-hand side of the lawn mower.

To lower the cutting height move the lever to the right and then forward.

To raise the cutting height move the lever to the right and then backward. Never run with the machine when it is running. You should always walk with the lawn mower. Pay particular attention when pulling the machine towards you during work. 82 – English Do not set the cutting height too low as there is a risk that the cutters might hit slopes with unevenness. ASSEMBLY Fitting the handlebar Assembly of the catcher Take care not to damage the cables and wires when you fold up the handlebar. Lift up the handlebar until the handlebar's upper tubular construction comes directly opposite to the handlebar's lower section. Tighten the knob correctly. Dismantling and assembling the cutter

WARNING! Always wear heavy-duty gloves when servicing and maintaining the cutting equipment. The cutters are very sharp and cuts can occur very easily. The ignition lead should always be removed from the spark plug before repair, cleaning or maintenance work. Always empty the fuel tank before you place the lawn mower on its side. Dismantling

Unscrew the bolt holding the cutter.

Remove bolt, washer and cup spring.

Remove the cutter. Assembly

LC48, LC48V, can be used with mulching function in the following way: Lift up the back shield and remove the container. Insert the mulching plug into the collector channel. Close the shield and ensure that it is locked with the mulching plug. 84 – English FUEL HANDLING Fuel Fuelling WARNING! Always ensure there is adequate ventilation when handling fuel.

WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel. Petrol Always shut off the engine before refuelling.

Use good quality unleaded petrol. Leaded petrol can be used if unleaded petrol is not available. When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Fuel should be at least 77 octane. Tighten the fuel cap carefully after refuelling.

If the machine is not used for some time the fuel tank should be emptied and cleaned. Always move the machine away from the refuelling area before starting. Engine oil Do not fill too much petrol. Leave about 35 mm under the filler cap so that the fuel can expand. Check the oil level before starting the lawn mower. A too low oil level can cause serious damage to the engine.

For the best result and function use HUSQVARNA fourstroke oil.

If HUSQVARNA four-stroke oil is not available, you may use another four-stroke oil of good quality. Contact your dealer when selecting oil. In general SAE 30 is recommended.

Never use oil intended for two-stroke engines. Clean around the fuel cap. Clean the fuel and oil tank regularly. The fuel filter should be changed at least once a year. Contamination in the tanks causes malfunction. Always move the machine about 3 metres from the refuelling position before starting. Check the oil level before starting the lawn mower. A too low oil level can cause serious damage to the engine. Oil level Unscrew the oil filler cap and check the oil level on the dipstick fitted to the cover. The oil filler cap must be completely screwed down to give a correct picture of the oil level. If the oil level is low, fill using engine oil up to the upper level on the dipstick.

Only use recommended engine oil. See the Technical data section. English – 85

STARTING AND STOPPING

Starting and stopping

WARNING! Note the following before starting: Drive The machines are self-propelling with backwheel drive. To use the drive on the wheel pull the clutch lever towards you. Do not start a lawn mower unless the cutter and all covers are fitted correctly. Otherwise the cutter could come loose and cause personal injuries. Always move the machine away from the refuelling area before starting. The drive can be gradually controlled. Place the machine on a flat surface. Ensure the cutting attachment cannot come into contact with any object. Keep people and animals well away from the working area. Starting Stopping Ensure the ignition lead sits correctly on the spark plug. Stop the engine by releasing the engine brake handle. Pull the engine brake handle against the upper handlebar with your left 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. Never twist the starter cord around your hand. 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. 86 – English Emptying the grass collector, LC48, LC48V

Lift up the back shield and remove the container.

Turn the container upside down to empty it of all the grass. MAINTENANCE Maintenance Spark plug

WARNING! Make sure the cutting attachment has stopped before cleaning, carrying out repairs or an inspection. Disconnect the HT lead from the spark plug. The ignition lead should always be removed from the spark plug before repair, cleaning or maintenance work. WARNING! The muffler gets very hot in use and remains so for a short time afterwards. Do not touch the muffler if it is hot! 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. The spark plug should be replaced after about a month in operation or earlier if necessary. 0,5 mm Air filter The air filter must be regularly cleaned to remove dust and dirt in order to avoid:

Loss of engine power

Unnecessary wear to engine parts.

Excessive fuel consumption. 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. Cleaning the air filter CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Muffler 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. Regularly check that the muffler is securely attached to the machine. Remove the air filter cover. Never use a machine that has a faulty muffler. Remove the air filter and check that it is undamaged. Replace with a new air filter if you believe it to be defective. Clean the filter by knocking the filter against a flat surface. Never use solvent with petroleum, for example, kerosene, or compressed air to clean the filter. When reassembling, make sure that the filter completely seals against the filter holder. English – 87 MAINTENANCE Cutter

Unscrew the oil filler cap.

The oil can be drained from the underside by loosening the oil plug. Do not forget to refit the oil plug before filling with oil again. WARNING! Always wear heavy-duty gloves when repairing the cutting attachment. The blades are very sharp and can easily cause cuts. It is important to have a sharp and correctly balanced cutter. Loosen the bolt holding the cutter and leave the cutter at a service workshop at least once a year for grinding and balancing. An appropriate time to do this is after the mowing season has finished. Ask where you can dispose of surplus engine oil at your local petrol station.

Fill with new engine oil of a good quality. See the Technical data section.

Check the oil level with the dipstick on the oil filler cap.

The oil filler cap must be completely screwed down to give a correct picture of the oil level. If the oil level is low, fill using engine oil up to the upper level on the dipstick. If the cutter or cutter bracket need to be changed you must replace the cutter bolt, washer and cup spring at the same time.

The bolt should be tightened with a torque of 45-60 Nm when you fit the cutter again. See instructions under the heading Assembly. If the cutter hits foreign objects such as stones, roots or the like the cutter will slip against the cutter bracket. This may mean that the contact surface of the cutter bracket appears slightly worn, which is completely normal. This is a safety device, which reduces the risk of the engine shaft becoming bent.

Screw on the oil filler cap. Drive and gearbox Changing the oil The engine oil should be changed each year and every 25 working hours. LC 48V When changing the oil proceed as follows::

Lift up the back shield and remove the container.
