The WORX WG320 Max Lithium Cordless JawSaw has all the features of the standard JawSaw plus cordless convenience. Powered by a Worx 20-volt Max lithium battery, the JawSaw is now free of cords and portable. This cordless JawSaw is the lightweight, portable and safe way to tackle pruning and trimming jobs around the house, camping or after storm damage. No pull starting; no more gas/oil mixes; no more exhaust smells; safer and no more tangled cords. The 20-volt MAX lithium battery technology resists self-discharge for much longer periods of time, and it has the ability to perform a quick partial charge without worrying about "memory effect" damaging your battery. The LithiumPower battery is lighter in weight and more compact. The JawSaw features auto-tensioning which guarantees optimum tension on the chain, along with an automatic oiler with level indicator to keep chain maintenance and performance at its peak. The enclosed bar and chain not only is safer, but it also limits dangerous kickback allowing for cuts to be made directly on the ground without propping. The WG320 cordless JawSaw is the safer, easier and portable way to trim and cut wood debris less than 3.5 inches in diameter. The cordless JawSaw is the perfect chainsaw for cutting up kindling wood, camping and around the house pruning or debris cleanup.
