Important Notes

• Verify part number 580943801 before ordering
• Confirm compatibility with your specific Husqvarna chainsaw model and fuel tank
• Compare the existing cap diameter, attachment or thread configuration, sealing surface, profile, grip design, and overall configuration before replacement
• Do not assume compatibility based solely on the cap’s appearance
• Confirm whether your chainsaw requires a particular venting configuration; do not substitute between vented and non-vented designs unless specified as compatible
• Inspect the fuel tank filler neck, threads or attachment points, and sealing surface for cracks, contamination, wear, or damage
• Verify whether the cap includes or requires a gasket, seal, tether, or other associated component
• Ensure the replacement cap seats correctly and closes securely before operating the chainsaw
• If fuel leakage or fuel odor remains after replacement, inspect the surrounding fuel tank, fuel lines, fittings, grommets, and sealing surfaces for damage
• Allow the chainsaw to cool before opening or servicing the fuel system, and keep gasoline away from flames, sparks, hot surfaces, and other ignition sources
