Thanks for reaching out—and we’re glad the pole saw has served you well for those high branches! For the rusted spring and chain, here’s how you can clean and maintain them:\n\nRemove loose rust: Use a wire brush or fine steel wool to gently scrub away surface rust from the spring and chain.\n\nApply rust remover: A rust-dissolving product (like WD-40 Specialist Rust Remover Soak or vinegar for a gentler option) can help break down deeper corrosion. Let it sit per product instructions.\n\nWipe clean & dry: After treating, thoroughly wipe down and dry all parts to prevent further rust.\n\nLubricate: Use a light machine oil or silicone lubricant on the chain and spring to keep them moving freely and protected from moisture.\n\nGoing forward, store the tool in a dry area and apply oil periodically to prevent new rust.

Thanks for sharing your experience with the Chain-drive Extendable Pole Saw & Pruner. We’re sorry to hear that the lopper mechanism didn’t hold up—especially after light use. The tool is designed to handle high branches with control and power, and it should certainly be able to manage branches of that size without failure.
