Power through tough cuts with an all-electric chainsaw designed for serious throughput. The Greenworks 82V Optimus 3.0 kW 18" Chainsaw Kit (OCS500-C4DP-18) delivers a 3.0 kW power output-equivalent to a 50cc gas chainsaw-so you get high-demand performance without gas mixing, pull starts, or exhaust.

At the core is a commercial-grade brushless motor built for reliability and reduced maintenance. Its lightweight, portable design supports all-day maneuverability, helping operators stay productive with less fatigue during limbing, bucking, and cleanup work.

Jobsite-ready features make field work faster and easier: an automatic, adjustable oiler keeps the bar and chain running smoothly with control tuned to your conditions, while the side-access chain tensioner allows quick adjustments without slowing the crew down. With IPX5 weather resistance, you can keep moving when the forecast doesn’t cooperate.

The built-in HMI (Human-Machine Interface) technology provides at-a-glance battery status and diagnostics that remain visible in full daylight-so operators can stay informed and minimize downtime.
