Frequently asked questions

What is the Echo CS-310 best suited for?

Echo lists the CS-310 for general trimming and limbing. With a 30.5 cc two-stroke engine and a recommended 35.56 cm bar, the CS-310 is aimed at branch work, small firewood and tidying up a garden or plot. It is a light-duty saw rather than a felling machine for mature timber.

What bar length can the Echo CS-310 run?

Echo gives the CS-310 a recommended bar length of 35.56 cm and a maximum of 40.64 cm. The 35.56 cm setup keeps the saw balanced and quick in the hand for limbing, while the 40.64 cm bar adds reach on thicker wood at the cost of asking more from the 30.5 cc engine.

How much does the Echo CS-310 weigh?

The Echo CS-310 weighs 3.99 kg without bar and chain, which is light for a petrol saw. Adding the 35.56 cm bar, the chain, fuel and chain oil raises the working weight, but at roughly 4 kg dry the CS-310 stays easy to hold at arm's length while limbing for long stretches.

What are the tank capacities of the Echo CS-310?

The Echo CS-310 carries 0.25 litres of fuel and 0.26 litres of chain oil, so the oil tank is marginally the larger of the two. That balance means a tank of mix will not outlast the bar oil, and one stop refills both. Top up the CS-310 oil tank at every refuelling anyway.

Can the Echo CS-310 fell trees?

The Echo CS-310 is listed by Echo for general trimming and limbing, not felling, and its 30.5 cc engine and 40.64 cm maximum bar set the limit. Small trees well within that bar length are within reach, but repeated felling of mature trunks calls for a larger-displacement saw than the CS-310.

Guides that cover this model

How to Choose a Chainsaw: A Practical Buyer's Guide A beginner's route through the decisions that actually determine which chainsaw you need: the job, the power source, the bar length, and the weight you can still hold up after two hours. 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.
