How to Troubleshoot a Husqvarna Backpack Blower


Power blowers help homeowners gather and remove yard debris. Backpack-style blowers offer the convenience of hands-free operation, which reduces the effects of vibration on your hands and arms. Knowing how to troubleshoot your Husqvarna blower if it has a problem could save you money and spare you a visit to a service center.

Things You'll Need

  • Fuel
  • Fuel stabilizer
  • 2-cycle engine oil
  • Fuel filter
  • Fuel line
  • Spark plug
  • Cloth
  • Air filter
  • Check the fuel tank if the engine will not start. Fill the tank with fresh, properly mixed and stabilized fuel. Open the choke halfway and attempt to start the engine.

  • Check the fuel filter if the blower has fuel. The fuel filter may be clogged; if so, replace it. Also check the fuel line for obstructions and damage.

  • If the engine will not start again, remove the spark plug after the engine has cooled. Replace the spark plug if it is damaged or shows signs of wear. If the spark plug is dirty, wipe it off with a clean cloth, check the gap and reinstall the spark plug. The correct gap is between 0.6 and 0.7 inches.

  • Check the air filter if the engine will not operate properly. Open the air filter housing and remove the filter. If the filter is dirty, replace it with a new unit.

  • Turn off the engine if it smokes excessively; it is likely that the fuel/oil mixture is incorrect. Drain the fuel from the tank and add fuel that has been correctly mixed at a 50-to-1 ratio.
