The Worx 12” – 40V (2X20) Chainsaw is your solution when traditional chainsaws are a hassle. Two 20V Powershare batteries provide gas-like performance, without the inconvenience of gasoline. And the ergonomic design makes it easy for almost anyone to use. This compact and lightweight chainsaw weighs in just under 10 lbs., so you can carry it all over the yard without getting tired. Its cordless design gives you even more freedom to roam. Try doing that with your old chainsaw. In addition to portability, battery-powered chainsaws are much easier to start. Not needing gas saves you time and money, plus these cleaner machines won’t make the whole neighborhood smell like gasoline. The automatic maintenance features make this saw an easy tool to keep in tip-top shape. Auto chain tensioning and lubrication allows the chain to run efficiently whenever you take it out for a spin. And the oil level indicator lets you know when you need to fill it back up. Here’s a modern chainsaw for the modern Do It Yourselfer.

What replacement bars and chains are available?

What type of oil do I use with the chainsaw?

Oil is not included with the sale of this chainsaw. This chainsaw can take any kind of bar and chain oil, which is available in most hardware stores that sell chainsaws.

How can I prevent oil leakage?

To help minimize and prevent leakage while being stored, we recommend loosening then retightening the oil cap to release any built-up pressure after use, wiping down the tool after use, and storing it horizontally (oil cap facing up) when not in use.

How does the chain-brake function work?

The chain-brake lever is a safety mechanism activated through the front handguard. When kickback occurs, the chain will stop immediately. To disengage it, pull the front handguard toward the operator until it “clicks” into position.
