The Echo CS-7310SX is the Japanese manufacturer’s largest and most powerful professional chainsaw, and as such offers the sort of reliability, handling and performance that are a must-have for the commercial forester!

The very high-performance 73.5cc (5.5hp) engine on the Echo CS-7310SX Petrol Chainsaw develops around 20% more power than the engine on the CS-621SX, and has been fitted with a premium-grade diaphragm carburettor, which maintains the ideal fuel/air mixture during acceleration so as to eliminate power loss.

There’s also a substantial automotive-style air filter, which protects crucial parts from undue wear and tear; a tool-free air filter cover, which makes routine maintenance simple when in the field; and Echo’s G-Force pre-cleaner, which extends periods between filter cleaning/replacement.

This top of the range model has been equipped with an automatic chain oiler, which can be adjusted suit the bar length, the hardness of the wood and the speed of cut that’s required. The flow is halted when the revs are at idle, and can be manually over-ridden for improved oil economy.

In order to maximise user safety, Echo have fitted the CS-7310SX with an inertia-triggered chain brake, which will bring the chain to an immediate halt in the unlikely event the saw ‘kicks back’.

Echo’s Performance Cutting System™, which includes an upgraded steel cutter bar and a highly aggressive chain, guarantees a fast, clean cut in the most demanding of conditions; their provision of a six-point vibration damping system works to spare the operator’s hands and arms from excessive stress and strain.

The premium features don’t stop there – you’ll also get a decompression valve for low-effort pull starts; a magnesium chain cover, which minimises weight and maximises durability; and a rubber handle cover for a firm, positive grip.

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.
