Husqvarna 350BT 50.2 cc Gas Backpack Leaf Blower OVERHEATING Error Fix: Engine Overheating

The engine overheats during extended use causing power loss — clean the cylinder cooling fins and flywheel air intake of all debris; the 350BT operates in very dusty conditions which accelerates cooling system clogging; using the wrong fuel mix ratio (too little oil) causes increased friction and overheating; check that the muffler and spark arrestor screen are not carbon-clogged restricting exhaust flow
