Greenworks 40V 18 in Cordless Chainsaw — 8.0Ah Battery Included, Brushless Motor & Tool-less Tensioning

The Greenworks 40V 18-inch cordless chainsaw is a brushless, battery-powered saw that delivers gas-like cutting performance without fumes, and ships with an 8.0Ah battery and charger.

This chainsaw is part of Greenworks' 40V lithium-ion family, a modular battery system that fits dozens of outdoor tools. The included 8.0Ah pack gives extended runtime for demanding yard jobs, while the brushless motor and 18" bar make it capable of tackling medium trees, storm cleanup, and regular firewood cutting. It’s engineered to offer easier ownership than gas models — no fuel mixing, no pull starter, and less maintenance over time.

How powerful is this chainsaw compared with gas and smaller cordless models?

The brushless motor and the 40V 8.0Ah battery combine to provide steady, fade-free power that closely approaches small gas saw performance for typical homeowner tasks. Because the motor is brushless it runs more efficiently and with less wear, extending useful life and runtime per charge. Greenworks rates the saw to make up to roughly 250 cuts through 4x4 lumber on a single full charge under representative conditions.

• 18" bar and chain for deeper cuts and longer reach.
• Brushless motor for improved efficiency and longevity.
• Estimated up to ~250 cuts on 4x4 lumber per full charge (varies by conditions).
• Included 8.0Ah battery for extended runtime; charger included for quick turnaround.

What maintenance and convenience features does it include?

Greenworks designed the saw for straightforward upkeep and everyday convenience. Tool-less tensioning makes bar-and-chain adjustments fast and safe, while an automatic oiler keeps the chain lubricated during operation to extend bar and chain life. Starting is as simple as a push-button — no choke, no spark plug, and no carburetor to service.

• Tool-less chain tensioning for quick adjustments without tools.
• Automatic oiler that delivers lubrication during use.
• Push-button start for hassle-free operation and repeatable starts.
• No gas, no fumes, and reduced routine maintenance compared with gas engines.

How does it fit into the Greenworks 40V battery ecosystem?

This saw is part of the 40V platform, which powers a wide range of Greenworks outdoor equipment from mowers to blowers and trimmers. Batteries on this platform deliver fade-free output and do not suffer memory loss after charging. Selected 40V battery models even include USB ports so you can use the battery as a power bank for small electronics when not in use.

• Compatible with Greenworks 40V tools for flexible battery interchangeability.
• Batteries available in multiple capacities (2Ah–8Ah) to suit runtime needs.
• Certain battery models feature integrated USB ports for device charging.
• 3-year warranty on tool and battery to protect your purchase.

Is this chainsaw safe and easy enough for non-professional users?

The saw includes user-friendly safety and handling elements designed for homeowner use. The absence of fuel systems removes many common gas-related hazards, while the automatic oiler and tool-less adjustments reduce the chance of incorrect maintenance. However, safe cutting practices, proper protective gear, and reading the manual remain essential for any operator.

• Less maintenance and simpler startup lower the learning curve for new users.
• Automatic lubrication and easy tensioning promote safe, reliable operation.
• Lightweight cordless design improves maneuverability and reduces fatigue.
• Always follow safety guidelines and wear appropriate PPE when cutting.

Who is this for: homeowners and property stewards who want a powerful, low-maintenance alternative to small gas chainsaws — ideal for trimming limbs, cutting firewood, storm cleanup, and regular yard upkeep. It also suits anyone already invested in the Greenworks 40V battery lineup who wants to expand their toolset with an 18" chainsaw backed by a 3-year tool/battery warranty.
