Safety instructions for operation
Personal protective equipment

WARNING: Read the warning instructions that follow before you use the product.

• Personal protective equipment cannot fully prevent injury but it decreases the degree of injury if an accident does occur. Let your dealer help you select the right equipment.
• Use hearing protection if the noise level is higher than 85 dB.
• Use heavy-duty slip-resistant boots or shoes. Do not use open shoes or go with bare feet.
• Use heavy, long pants.
• Use protective gloves when necessary, for example when you attach, examine or clean the cutting equipment.

Safety devices on the product
WARNING: Read the warning instructions that follow before you use the product.

• Do not use a product with defective safety devices.
• Do a check of the safety devices regularly. If the safety devices are defective, speak to your Husqvarna service agent.

To do a check of the cutting cover
The cutting cover decreases vibrations in the product and decreases the risk of injury from the blade.

• Examine the cutting cover to make sure that there are no damages such as cracks.

Battery (LC 347VE, LC 353VE)

WARNING: A defective battery decreases the safety of the product. Always use a battery approved by the manufacturer.
The battery gives power to the electrical start and is a safety device that prevents accidental start. Remove the battery when you do not operate the product and when you let it stay out of view.
To do a check of the engine brake handle
The engine brake handle stops the engine. When the engine brake handle is released, the engine stops.

• Start the engine and then release the engine brake handle. If the engine does not stop in 3 seconds, let an approved Husqvarna service agent adjust the engine brake. (Fig. 18)

Muffler
The muffler keeps the noise levels to a minimum and sends the exhaust fumes away from the operator.
Do not use the product if the muffler is missing or defective. A defective muffler increases the noise level and the risk of fire.
WARNING: The muffler becomes very hot during and after use and when the engine operates at idle speed. Be careful near flammable materials and/or fumes to prevent fire.

To do a check of the muffler

• Examine the muffler regularly to make sure that it is attached correctly and not damaged.

Fuel safety

WARNING: Read the warning instructions that follow before you use the product.

• Do not start the product if there is fuel or engine oil on the product. Remove the unwanted fuel/oil and let the product dry.
• If you spill fuel on your clothing, change clothing immediately.
• Do not get fuel on your body, it can cause injury. If you get fuel on your body, use soap and water to remove the fuel.

• Make sure that the ignition cable is connected to the
  spark plug.

Manual start (LC 247, LC 247S, LC 253S, LC 347V, LC 353V)

1. Stay behind the product.
2. Hold the engine brake handle against the handlebar. (Fig. 28)
3. Hold the starter rope handle with your right hand.
4. Slowly pull out the starter rope until you feel some resistance.
5. Pull with force to start the engine.

WARNING: Do not twist the starter rope around your hand.

Electrical start (LC 347VE, LC 353VE)

1. Make sure that the battery is charged. Refer to To use the battery for the first time on page 14.
2. Attach the battery to the engine. The battery locks into position when you hear a click. (Fig. 29)

• Push the lock button (A) and pull the battery straight out. (Fig. 33)

To get a good result

• Always use a sharp blade. A blunt blade gives an irregular result and the cut surface of the grass becomes yellow. A sharp blade also uses less energy than a blunt blade.
• Do not cut more than ⅓ of the length of the grass. Cut first with the cutting height set high. Examine the result and lower the cutting height to an applicable level. If the grass is very long, drive slowly and cut 2 times if necessary.
• Cut in different directions each time to prevent stripes in the lawn.
• Keep the cutting cover clean. Buildup from grass and dirt on the inner side of the cutting cover can decrease the cutting result. Refer to To clean the inner surface of the cutting cover on page 13.

Transportation, storage and disposal

Transportation and storage

• For storage and transportation of the product and fuel, make sure that there are no leaks or fumes.
  Sparks or open flames, for example from electrical devices or boilers, can start a fire.

• Always use approved containers for storage and transportation of fuel.

• Empty the fuel tank before you put the product in storage for a long period of time. Discard the fuel at an applicable disposal location

• Safely attach the product during transportation to prevent damage and accidents.

• Keep the product in a locked area to prevent access for children or persons that are not approved.

• Keep the product in a dry and frost free area.

Transportation and storage for battery and charger

• Do not remove the battery until the product is stationary and cool. To remove the battery, press and hold the button on the top of the battery and remove it from its slot.
• If the time of storage is more than 30 days, charge the battery until it has more than 3 green lights.
• Charge the battery one time each 3 months to prevent damage to the battery.
• The battery and battery charger must be kept in storage between 5 °C and 40 °C. Higher temperatures or high temperature sources, such as fire, can cause damage to the battery.
• Do not disassemble the battery.
• Do not put the battery fully into water. Keep the battery in a cool and dry environment with good airflow.
• If the battery smells, is hot or if the heat causes deformation to the battery during operation, storage or charging, remove the battery and do not use it.
• Make sure that the battery or battery charger are attached during transportation to prevent damage.
• Make sure that the battery charger does not become too hot.

Disposal

• Obey the local recycling requirements and applicable regulations.
• Discard all chemicals, such as engine oil or antifreeze, at a service center or at an applicable disposal location.
• When the product is no longer in use, send it to a Husqvarna dealer or discard it at a recycling location.
• Discard the battery at a service center or discard it at a disposal location for used batteries.

3 The power rating of the engine indicated is the average net output (at specified rpm) of a typical production engine for the engine model measured to SAE standard J1349/ISO1585. Mass production engines may differ from this value. Actual power output for the engine installed on the final product will depend on the operating speed, environmental conditions and other values.
4 If SAE-30 oil is used at temperatures lower than +5 °C, there is a risk that it does not lubricate the engine sufficiently. This can cause engine damage. Refer to To replace the engine oil on page 14 for the correct oil for low temperatures.
5 Noise emissions in the environment measured as sound power (LWA) in conformity with EC directive 2000/14/EC.
6 Reported data for noise pressure level has a typical statistical dispersion (standard deviation) of 1.2 dB (A).
7 Reported data for vibration level has a typical statistical dispersion (standard deviation) of 0.2 m/s² .
