  Michele OrtizJul 31, 2025
  Your Husqvarna Chainsaw might not start due to several reasons: the ignition switch may be off (move it to ON), the engine could be flooded (refer to the ”Start” section in the STARTING AND STOPPING section), the fuel tank might be empty (fill it with the correct fuel mixture), the spark plug may not be firing (install a new one), or fuel isn't reaching the carburetor (check for a dirty fuel filter and replace it, or check for a kinked or split fuel line and repair or replace it).

  If your Husqvarna Chainsaw won't accelerate, lacks power, or dies under a load, it could be due to a dirty air filter (clean or replace it), a fouled spark plug (clean or replace it and regap), or the chain brake might be engaged (disengage the chain brake). For carburetor adjustments, contact an authorized service dealer.

  Joshua DeanAug 25, 2025
  The chain moving at idle speed on your Husqvarna Chainsaw can be caused by the idle speed requiring adjustment (refer to ”Fine adjustment of the idling speed T” in the MAINTENANCE section). If that doesn't solve the issue, the clutch may require repair, and you should contact an authorized service dealer.
