Husqvarna 455 Rancher 55.5 cc 3.5 HP Gas Chainsaw with X-Torq Engine and Air Injection AIR FILTER Error Fix: Air Filter Clogged or Restricted

The air filter is clogged with sawdust and debris, reducing engine power and causing rich running conditions — Husqvarna chainsaws with Air Injection technology use centrifugal force to remove most debris before it reaches the filter, but the filter still requires regular cleaning; remove the top cover, take out the air filter, and tap it clean or wash with warm soapy water and dry completely before reinstalling; a clogged filter causes the engine to run rich (too much fuel, not enough air), resulting in black smoke, poor power, and fouled spark plugs
