• 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.

• Do not make modifications on safety devices 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 (LB 246E)
WARNING: A defective battery
decreases the safety of the product. Always use a battery approved by the manufacturer.

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.

• Do not start the product if the engine has a leak. Examine the engine for leaks regularly.

Before you operate the product

1. Read the operator’s manual carefully and make sure that you understand the instructions.
2. Examine the cutting equipment to make sure that it is correctly attached and adjusted. Refer to To examine the cutting equipment on page 13.
3. Do a check of the oil level and fill with engine oil if it is necessary. Refer to To do a check of the oil level on page 13.
4. Fill the fuel tank. Refer to To fill fuel on page 11.

To fill fuel
If available, use low-emission/alkylate gasoline. If lowemission/alkylate gasoline is not available, use good quality unleaded gasoline or leaded gasoline with octane
number not less than 90.
CAUTION: Do not use gasoline with an octane number less than 90 RON (87 AKI).
This can cause damage to the product.

5. Move the product a minimum of 3 m (10 ft) from the position where you filled the tank before a start.
   To set the cutting height
   • Press the shaft out and move it to the correct position for each of the 4 wheels. (Fig. 31)
   CAUTION: Do not set the cutting height too low. The blades can hit the ground if the surface of the lawn is not level.
   To start the product
   • Make sure that the ignition cable is connected to the spark plug.

Manual start (LB 146)

1. Stay behind the product.
2. Hold the engine brake handle against the upper handle. (Fig. 32)
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 (LB 246E)

1. Make sure that the battery is charged. Refer to Battery (LB 246E) on page 13.
2. Attach the battery to the engine. The battery locks into position when you hear a click. (Fig. 33)
3. Stay behind the product and hold the engine brake handle (A) against the upper handle. (Fig. 34)
4. Push and hold the electrical start button (B) for 3-5 seconds. The engine starts.
   Note: If the engine does not start, wait 1 minute and try to start the product again.

To stop the product

• To stop the engine, release the engine brake handle.
  To remove the battery (LB 246E)
  To prevent accidental start of the engine, remove the battery when the product is not in operation.

• Push the lock button (A) and pull the battery straight out. (Fig. 35)
  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 12.

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 13 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/s 2 .
