Difference Between CS-290EVL and CS-290EVLP
The Echo CS-290EVL and CS-290EVLP are very similar chainsaws, but they do have a few notable differences. The CS-290EVL was the original model introduced in 1981, while the CS-290EVLP was introduced later and was available for a shorter period of time. The main difference between the two models is the type of bar and chain that they use. The CS-290EVL uses a 1/4 inch or 3/8 inch low profile chain, while the CS-290EVLP uses a 3/8 inch pitch chain.
Additionally, the CS-290EVLP has a slightly lower weight than the CS-290EVL, coming in at 3.7 kg (8.2 lbs.) for the powerhead only, compared to the CS-290EVL’s 3.8 kg (8.4 lbs.). These differences may not seem significant, but they can impact the saw’s performance and make a difference depending on the user’s needs.
To sum up, the Echo CS-290EVL was a high-quality chainsaw that was manufactured by the Kioritz Corporation (Echo) and introduced in 1981. With its powerful engine, anti-vibration handlebar system, and automatic oil pump, it was well-suited for a variety of cutting tasks. Its sturdy construction and reliable performance made it a great choice for both professional and DIY use.
