- Requires platform batteries
The Straight-Shooter Take
Two-cycle gas chainsaws sit in the barn for six months, gum up their carburetors with ethanol, and make you pull your shoulder out trying to start them. When storm limbs come down on the field fence, this Ryobi 40V HP saw is ready the instant you slap a battery in and pull the trigger.
Where It Earns Its Keep
- Pure Torque: Bucked thru 16-inch thick green oak logs without stalling or binding up the chain.
- Mechanical Chain Brake: Instant inertial chain brake stops blade rotation instantly for jobsite safety.
- Auto-Oiler with Visible Window: Keeps the 18-inch bar flooded with bar-and-chain oil without leaking all over the shop floor when sitting.
