The finest top quality, Japanese-engineered Echo CS-450 is a high-powered mid-range saw that’s ideal for heavy-duty lopping & felling applications in domestic, professional & agricultural arenas. Its lengthy 40cm cutting-gear is driven by a beefy but refined 45cc (1.9k W) two-stroke engine, which employs Echo’s innovative Power Boost Tornado™ technology. This improves combustion efficiency & power delivery, while simultaneously working to minimise harmful exhaust emissions & fuel-costs. The engine also features flywheel-type air pre-cleaning for the best possible performance in dry, dusty conditions. ‘ Kick back’, which occurs when one of the chain-teeth strikes a stubborn knot in the wood, can be dangerous. Echo have got around this problem by fitting the CS-450 with a super-fast-acting chain-brake, which bites & stops the chain as soon as any inertia is identified. The Echo CS-450 Petrol Chainsaw features an adjustable automatic chain-oil pump, so you can select the most effective flow-rate for the hardness of the timber you’re faced with. The oil-flow stops when the engine idles, thus avoiding mess & waste. This well-balanced, easy-handling machine has been equipped with a series of six vibration-absorbing mounts & weighs-in at only 5kg; a combination that ensures time-consuming tasks can be finished in comfort.
