The chainsaws include two saws that will replace previous models and two upgrades to existing models.
Two of the new chainsaws, the CS-4920 and CS-4010, will replace the CS-4910 and CS-400 and will offer more power and lower emissions. The other two saws, the CS-2511TN and CS-2511PN, have been upgraded to include a new SpeedCut Nano 80TXL cutting system.
The Echo CS-4920 50.2 cc rear handle chainsaw is a lightweight, powerful tool that is ideal for large landowners who fell and buck trees, process firewood or have storm clean ups. While it replaces the CS-4910, its stratified 2-stroke engine has lower emissions and features the same powerful performance, now with a common bar mount, added purge bulb and momentary switch.
The Echo CS-4010 41.6 cc rear handle chainsaw replaces the CS-400. The new i-30™ starter reduces starting effort by 30%, it’s 0.7 lb (0.3 kg) lighter and features 13% more power than its predecessor. An ideal saw for homeowners, it can be used for a wide range of applications from cutting firewood to storm cleanup.
Finally, designed to be the two lightest gas-powered chainsaws in North America, are the CS-2511TN and CS-2511PN. These saws feature the new SpeedCut Nano 80TXL cutting system, a smaller chain chassis optimized for saws in the 1 to 3 hp range. This system features a .325-inch low-profile chain combined with a .043-inch gauge bar, as well as a system-specific sprocket to deliver increased cutting speed and a smoother cut. All chainsaws come with an unmatched industry warranty that includes a two-year commercial warranty and a five-year consumer warranty. Source
