What's Included:

Features:

• [FAST, CLEAN CUTS] This cordless 20V PowerShare chain saw is as fast and powerful as anything in its class. And with no gas and no cord, theres much less muss and fuss. Please fill the oil tank with chain oil before using the chainsaw. Then, run the chain for a few seconds without cutting to help lubricate it better, oil is sold separately.
  
• [AUTO-CHAIN TENSION] The automatic, tool-free chain tension system ensures youll always have the correct tension for the job at hand
  
• [AUTO-CHAIN LUBRICATION] The automatic chain lubrication system not only makes for smoother, more efficient cuts, it extends the life of the tool. And the oil level indicator lets you know exactly where you stand
  
• [COMPACT, LIGHTWEIGHT] It weighs 6.2 lbs., about as much as a 2-Liter bottle of soda. Youll work longer, with less strain
  
• [A FAST CHAIN SPEED] 12.5 ft/s. will tear through any reasonably sized log or branch. That speed, combined with our auto-tension and auto-oil systems, and the overall lightweight design, makes for one smooth saw experience
  
• [PLENTY OF JUICE] These are the same batteries we use on our Jawsaw and in our lawnmowers. Theyre powerful enough for those, and powerful enough for a chainsaw
