Important Notes

• Verify part number 578279503 before ordering
• Confirm compatibility with your specific Husqvarna equipment model, engine, and throttle-control configuration
• The exact control dimensions, cable length, housing length, lever configuration, end fittings, mounting style, and compatible equipment models are not identified in the supplied product information; verify these specifications before ordering
• Because this product is identified as a throttle control assembly, verify the exact assembly contents before purchasing
• Do not assume that additional cables, brackets, springs, clips, fasteners, linkages, knobs, or mounting hardware are included unless specifically stated
• Compare the original control’s overall length, mounting points, lever configuration, cable/housing dimensions, end fittings, travel, and routing
• Inspect associated throttle linkage, carburetor or throttle-body mechanism where applicable, governor components, springs, pivots, brackets, clips, and mounting points for wear, binding, or damage
• Ensure the throttle linkage and related components move freely throughout their intended range without sticking or binding
• Route any control cable or linkage in the correct position and keep it clear of hot surfaces, sharp edges, and moving components
• Do not bend, shorten, stretch, or otherwise modify the throttle control to fit an incompatible application
• Make sure the throttle mechanism returns and responds correctly according to the equipment manufacturer’s specified configuration
• If the engine speed remains incorrect after replacement, inspect the complete throttle linkage, governor system, carburetor/throttle mechanism, springs, and related controls
• After installation, verify proper mounting, routing, linkage movement, throttle travel, clearance, response, and engine-speed control before returning the equipment to normal operation
