Thank you for taking the time to share your review! We are glad to hear your 80V chainsaw made quick work of that large oak branch, but we are truly sorry to learn about the cracked crankcase after so few uses. Structural durability and safety are top priorities for us, and this is certainly not the experience we want you to have with our equipment.
To help protect your chainsaw's housing and drive assembly during heavy-duty cutting, here are a few practical maintenance and operational tips to keep in mind. Always verify proper chain tension before and during operation, as an over-tensioned chain can place excessive mechanical stress directly on the crankcase, drive sprocket, and bar mounting studs. Additionally, ensure the automatic oiling system is delivering adequate bar and chain lubricant, as high friction and heat from cutting dense hardwoods like oak can weaken internal assembly points if left unchecked. It is also helpful to routinely clear packed sawdust and sap from under the side cover to keep air flowing and prevent thermal stress around the motor housing.

Since you have already initiated a warranty claim, we want to ensure it is processed as quickly as possible. If you need to provide any remaining documentation to move your claim forward, such as photos of the damage, your order details, or the serial numbers from your tool, battery, and charger, please reply directly to your open case or reach out to our Customer Success Team so we can finalize your review and get you taken care of. If you are unable to locate our email, please call 1-888-909-6757 (1-888-90WORKS), or use the chat section on our website. Thank you again for your feedback. We are here to help.
