      Key benefits

      • 45 cm guide bar for heavy-duty work
      • Durable magnesium-alloy crankcase
      • Easy starting with integrated decompressor

      • Inertia chain brake for added safety

      A precise, long-lasting petrol chainsaw

      The ECHO X-Series 45 cm petrol chainsaw is designed for users looking for a rear-handle machine suited to regular, sustained cutting. The air-forced, ducted ECHO single-cylinder 50.2 cm³ 2-stroke engine delivers 2.57 kW to drive a 45 cm guide bar. The magnesium-alloy crankcase provides a robust build while keeping the weight to 4.7 kg without bar or chain. The 0.325" pitch chain, with 0.058" gauge and 72 drive links, is suited to cutting tasks that demand precision and productivity. The side tensioner simplifies adjustment, the adjustable automatic lubrication optimises chain oiling, and the anti-drop nuts make servicing easier. The tool-free air filter access and caps that can be handled with the starter-handle improve day-to-day maintenance.

      When to use it

      This petrol chainsaw is used for wood cutting that requires a 45 cm guide bar, fuelled by a mix of unleaded 95 or 95-E10 petrol and 2-stroke oil at 2%. The integrated anti-icing system, multi-position carburettor and electronic CDI ignition support work in a wide range of conditions.

      • Wood cutting with a 45 cm guide bar
      • Forestry work or outdoor maintenance
      • Extended use with adjustable chain lubrication
      • Jobs requiring quick access to the air filter

      Why buy it

      This ECHO X-Series chainsaw combines power, practicality and simplified maintenance in a format designed for cutting work. The magnesium crankcase, easy starting, inertia chain brake and accessible controls deliver a reliable, functional machine that inspires confidence in use.
