The Echo CS-4310SX is a premium, Japanese-built chainsaw that will prove just at home in the hands of the serious domestic user as it will in those of the professional landscaper!

Powering the easily manageable 33cm cutting gear on the Echo CS-4310SX Petrol Chainsaw is a medium-displacement 42.9cc two-stroke low-emission engine that outputs a sizeable 2.5hp, and which, thanks to Echo’s Easy Start system, requires only a gentle pull on the recoil rope to fire-up.

A multi-stage filtration system with a G-Force pre-cleaner extends the life of key engine parts by limiting their exposure to damaging debris particulates; a diaphragm-type carburettor ensures peak performance is consistently maintained by continuously optimising the fuel/air mixture.

To ensure you can be confident in terms of operational safety, Echo have equipped the CS-4310SX with a fast acting chain brake, which kicks-in instantly when inertia is detected (a chain catcher further enhances user safety).

It features auto/adjustable chain oiling for a smooth, low-temperature cut and superior flexibility of use, and it benefits from a no-tools air filter cover for hassle-free replacement/cleaning when you’re in the field.

Further attributes on the Echo CS-4310SX Petrol Chainsaw include a side-access chain tensioner, which makes adjustment quick and easy; a digital CDI for rapid acceleration and a smooth idle; and dropout-prevention nuts, which are designed to prevent loss.

This top-end X-Series model boasts a class-leading power to weight ratio, and is backed by an extended five-year manufacturer’s warranty for private use.

Shipping Info

Shipping Info

If you’re buying a boxed product, we aim to get your order delivered next working day – UK mainland where possible.

If you’re buying a tractor or ride-on mower – a special order item – it could be slightly longer, as we need to PDI the machine.

We do try and van-deliver these machines if we can, as this gives us a chance to demonstrate the product, and to ensure you’re happy and confident with your purchase.

If we can’t van-deliver your machine, as you’re out of our local delivery area, the tractor will be sent on a pallet via a courage company. They will then contact you directly to book a specific day and time that suits you.
