Echo CS-501SX Petrol Chainsaw 45cm/18" Bar

ECHO CS-501SX Rear-Handle Petrol Chainsaw – 18" (45 cm) Bar

The ECHO CS-501SX petrol chainsaw delivers professional-grade performance in an ultra-light frame. With a 50.2 cm≥ engine and 18" bar, it balances cutting power, weight, and reliability—perfect for limbing, felling, and heavy-duty forestry work.

Powerful Performance, Lightweight Frame

The 50.2 cm≥ two-stroke engine generates around 2.57 kW (‚âà 3.5 hp), yet the saw weighs just 4.7 kg (dry). This impressive power-to-weight ratio reduces fatigue during prolonged use and increases efficiency in professional settings.

Optimised for All-Weather Use

Designed with an anti-icing system and a decompression start-assist, the CS-501SX handles low-temperature starts with ease. Its ergonomic frame includes a magnesium crankcase, slim profile, and aluminium front handle with rubber grip for better comfort and control.

Built for Professionals

This model includes side-access chain tensioning, tool-free air filter access, and retained bar nuts to prevent part loss. A see-through fuel tank allows quick visual checks, and the large, glove-friendly filler openings make refuelling easy.

Comfort and Safety

A three-point anti-vibration system minimises strain, while the inertia-activated chain brake offers added protection. With low emissions, smooth handling, and rugged construction, it's a true workhorse for arborists and forestry pros.
