Echo Echo CS-680 chainsaw

Echo Echo CS-680

Built for demanding professional applications, this Japanese-engineered chainsaw combines robust performance with reliable operation. The CS-680's 66.8cc two-stroke engine delivers substantial power while maintaining manageable handling characteristics, making it suitable for heavy-duty forestry work, tree services, and commercial timber operations.

With its impressive 68.6cm maximum bar capacity, this model can tackle large diameter logs and challenging cutting tasks that would overwhelm smaller saws. Despite its powerful engine displacement, the unit maintains a relatively balanced 6.6kg weight (without bar and chain), reducing operator fatigue during extended use. The generous 0.64-liter fuel tank provides extended runtime between refueling stops, while the 0.37-liter oil reservoir ensures consistent chain lubrication throughout demanding cutting sessions.

Frequently asked questions

Who is the Echo CS-680 built for?

Echo classifies the CS-680 as a professional chainsaw, built around a 66.8 cc engine. That displacement puts it among the larger saws in this catalog, giving it the power reserve professional users need for repeated felling and bucking through a working day rather than occasional homeowner pruning around a yard.

What is the maximum bar length the Echo CS-680 can run?

The Echo CS-680 can run a bar up to 68.6 cm long. That maximum lets it handle wide trunks in a single pass, though fitting the full-length bar demands more engine power to keep chain speed up, so operators cutting smaller wood regularly may prefer a shorter bar for a livelier feeling saw.

How much does the Echo CS-680 weigh?

The Echo CS-680 weighs 6.6 kg without bar and chain. Once the bar, chain, fuel and the 0.37 litre oil charge are added, actual working weight climbs well past that figure. At over 6.6 kg dry, it is a substantial two-handed saw built for professional felling rather than light trimming work.

How much fuel and oil does the Echo CS-680 hold?

The Echo CS-680 carries a 0.64 litre fuel tank and a separate 0.37 litre bar oil tank. The larger fuel tank supports longer stretches of cutting between refills, which matters for a professional saw, while the 0.37 litre oil reservoir needs checking often enough to keep the bar and chain properly lubricated.

What kind of engine and fuel does the Echo CS-680 use?

The Echo CS-680 is powered by a 2-stroke engine running on a petrol-oil mix, standard for a professional gas chainsaw of this size. That 2-stroke design keeps the saw light relative to its 66.8 cc displacement, though it does mean mixing fuel correctly before every fill rather than running straight gasoline.

Guides that cover this model

Chainsaw Bar Length Guide: What Size Do You Need? Bar length decides the diameter of wood a chainsaw can cut, but a longer bar is only useful if the engine can pull it. This guide covers the two-cut rule, recommended versus maximum bar length, and the displacement each length needs. Chainsaw Engine Displacement (cc) Explained Displacement is a volume, not a power rating. This guide explains what cc measures, how it relates to kW and HP, why power-to-weight is the better comparison, and what the sub-40cc, 40-50cc, 50-60cc and 60cc-plus bands are for.
