What is the difference between the 4-inch and 6-inch versions?

The 6-inch model has a longer bar and chain, so it cuts thicker branches in one pass. The 4-inch is lighter and better for thin limbs and shrubs.

How long does the battery last?

Runtime depends on which bundle you choose and how hard you cut. Expect short sessions of light pruning per charge, and pick a bundle with a spare battery if you have a lot to cut.

Can it cut through a tree trunk?

No. It is a pruning saw for branches and small limbs. For trunks or thick logs you need a full-size chainsaw.

Small cordless saws of this type usually need bar and chain oil to run smoothly. Follow the directions supplied with the unit and check the oil before each use.

What comes in the box?

It varies by option: some bundles include one or two batteries, an extra chain, or a gift or plastic case. Check the option you select for the exact contents.
