Echo CS-501SX Chainsaw: The Lightest Pro 50cc Saw in Its Class
The Echo CS-501SX is a flagship model in Echo's elite X-Series lineup. Renowned as one of the lightest professional 50cc chainsaws on the market, it is engineered specifically for forestry workers, professional arborists, and demanding landowners who require maximum power-to-weight performance for heavy felling, limbing, and processing.
Key Specifications
Engine Displacement: 50.2 cc professional-grade, 2-stroke
Power Output: 2.57 kW (3.50 ps)
Dry Weight: 4.7 kg (Without bar and chain — an industry-leading weight for this displacement class)
Guide Bar Lengths: Compatible with 16", 18", and 20" (40 to 50 cm); typically supplied with an 18" (45 cm) bar
Fuel Tank Capacity: 0.50 Litres
Chain Oil Tank Capacity: 0.28 Litres
Saw Chain Pitch: 0.325"
Standout Professional Features
Unmatched Power-to-Weight Ratio: Weighing a mere 4.7 kg while churning out 2.57 kW, it provides incredible cutting speed and agility, drastically reducing operator fatigue during long shifts.
Pro-Grade Magnesium Die-Cast Crankcase: Built with a commercial-grade metal chassis and an aluminum front handle designed to withstand the harsh daily rigors of professional forestry and land clearing.
Decompression Valve: Lowers cylinder pressure during pull-ups for exceptionally smooth, low-effort starting.
Choke with Automatic Fast Idle Release: Automatically kicks down to a fast idle as soon as the throttle is touched, preventing engine flooding on startup.
Tool-Less Air Filter Access: Features a heavy-duty air filter cover that can be easily removed in the field—even when wearing thick work gloves.
Field-Ready Conveniences: Equipped with dropout-prevention bar nuts, a side-access chain tensioner, a translucent fuel tank for quick level checks, and a built-in anti-icing shutter valve for reliable cold-weather operation.
Ideal Applications
Tree Felling & Cross-Cutting: Offers the muscle needed to drop and buck mid-sized timber safely and efficiently.
Commercial Land Clearing & Forestry: A favorite among professional crews looking for high performance, reliability, and low operator strain.
