Important Notes

• Verify part number 590101401 before ordering
• Confirm compatibility with your specific Husqvarna chainsaw model and guide bar
• A 20" bar length alone does not determine chain compatibility
• Verify the required chain pitch, gauge, and drive-link count before ordering
• The replacement chain’s pitch, gauge, and drive-link count must all match the chainsaw and guide bar requirements
• Check the guide bar markings or equipment specifications to determine the correct chain configuration
• Compare the existing chain’s pitch, gauge, drive-link count, cutter configuration, and overall specification
• Inspect the associated guide bar, drive sprocket, clutch components, chain tensioner, and lubrication system for wear or damage before installing a new chain
• Ensure the chain is installed in the correct cutting direction and adjusted to the proper tension before operation
• Shut off the chainsaw, allow it to cool, and disconnect the applicable spark plug wire, battery, or power source before servicing the cutting system
• Wear appropriate protective gloves when handling or installing a chainsaw chain, as the cutters can be sharp even when the chain is not moving
