The chain is arguably the most crucial part of any chainsaw. A dull or improperly chosen chain can severely impact cutting performance, increase wear and tear on the saw, and even be dangerous.

Understanding Chain Types

There are several types of chainsaw chains, each designed for specific applications:

Full Chisel: These chains have square-cornered cutters that are very aggressive and fast-cutting. They are best suited for clean wood and experienced users.
Semi-Chisel: These chains have rounded cutters that are more forgiving and resistant to dulling. They are a good all-around choice for various wood types.
Low-Profile: These chains have a smaller profile and are designed for safety and ease of use. They are often used on smaller chainsaws.

For the Echo CS 370, I recommend using a semi-chisel chain as a starting point. It offers a good balance of cutting speed and durability. However, if you primarily cut clean, softwood, you might consider a full-chisel chain.

My Experience with Chain Selection

I remember one time I was cutting some seasoned oak with a full-chisel chain. The chain dulled quickly, and the saw was struggling. I switched to a semi-chisel chain, and the difference was remarkable. The saw cut through the oak with ease, and the chain stayed sharp longer.

Chain Sharpening: The Key to Performance

No matter what type of chain you use, it’s essential to keep it sharp. A dull chain is not only inefficient but also dangerous.

Here’s my sharpening routine:

Clean the chain: Use a brush to remove any dirt or debris.
Secure the saw: Place the saw in a vise or on a stable surface.
Use the correct file: Use a round file of the correct diameter for your chain (usually 5/32″ for the Echo CS 370).
Maintain the correct angle: Follow the manufacturer’s recommendations for the filing angle (typically 30 degrees).
File each cutter evenly: Make sure to file each cutter the same number of strokes to maintain balance.
Check the depth gauges: Use a depth gauge tool to ensure that the depth gauges are at the correct height.
Deburr the cutters: Use a flat file to remove any burrs from the cutters.

Data Point: Studies have shown that a properly sharpened chain can increase cutting speed by up to 30%.

Sustainable Tip: Invest in a quality chain sharpener and learn how to use it properly. This will extend the life of your chains and reduce the need to purchase new ones.
