Echo Chainsaw Sharpener: The Five Kits Echo Sells and Which One Fits Your Chain

Echo sells its chain sharpening kit in five file diameters, from 5/32 inch to 7/32 inch. Only one of those five fits your saw. That makes shopping for an Echo chainsaw sharpener less about brand and more about diameter.

This is not an electric tool. Echo’s own lineup is a set of file kits, sold by diameter and matched to chain pitch. This guide shows which kit fits which saw, and where a Stihl or Oregon file kit fills the gap.

What the Echo Chainsaw Sharpener Kit Actually Includes

Echo’s product page lists the Chain Sharpening Kit in five part numbers. Each part number matches one file diameter.

• 99988800720: 5/32 inch
• 99988800721: 11/64 inch
• 99988800722: 3/16 inch
• 99988800723: 13/64 inch
• 99988800724: 7/32 inch

Each kit ships in a velcro closed cloth pouch. The product page lists the contents as two round files, one flat file, a file guide, a depth gauge tool, and a plastic handle.

Echo’s own how to page describes the same kit a little differently. Contents there are listed as a file handle, a bar rail scraper and depth gauge tool, a flat file, a round file, an angle guide, and a filing reference card.

These are likely the same parts under two descriptions, not two different kits.

Echo also sells replacement round files on their own. They come in two packs and twelve packs, across all five diameters. A twelve pack of six inch flat files is sold separately.

There is no Echo branded electric or battery chain grinder listed among Echo’s chainsaw accessories. If you want power sharpening, that has to come from a separate brand.

Match the File to Your Chain

Every chain has a pitch and a gauge, and those two numbers decide which file diameter you need. Echo does not publish one master pitch to file chart online. Instead, Echo points owners to the filing reference card that ships inside the kit itself.

One example comes from Echo’s own parts catalog. The CS-490 runs 0.325 inch pitch chain at 0.050 inch gauge.

Echo lists the 3/16 inch kit, part 99988800722, as the matching accessory. That single pairing is the clearest diameter guidance Echo publishes anywhere.

Echo sells both the 5/32 inch and 11/64 inch kits. The product page does not say which chain each one fits.

Do not guess. Check the filing reference card, or compare your chain against a sizing tool before buying loose files.

Our tool to cross check pitch and gauge against file diameter covers this exact mismatch. For more on file geometry and technique, our broader guide to chainsaw files covers it saw by saw.

Read Your Bar and Chain Markings First

Pitch and gauge are usually stamped on the chain’s drive link. Sometimes they are printed on a sticker near the bar mount instead.

Your saw’s operator manual lists the factory chain part number too. That is the fastest way to confirm pitch without guessing from wear marks.

Echo’s CS-2511T top handle saw uses 91PXL and 90PX series chains. Bar lengths run 12 inch and 14 inch.

None of that tells you the file diameter on its own. It only narrows down which section of the filing reference card applies to your saw.

If you run a different brand, the sizing logic still holds even though the part numbers change. Our page for Husqvarna owners and our Stihl specific coverage both walk through the same pitch first approach.

Echo’s Sharpening Procedure

Running the Echo chainsaw sharpener kit correctly comes down to three habits: angle, depth gauge interval, and chain tension.

Echo’s how to page lists a filing angle range of 25 to 35 degrees. The range depends on chain type, sometimes with an added vertical tilt of up to 10 degrees. That range spans several chain styles, so the filing reference card still decides your exact number.

Depth gauges need attention too. Echo recommends lowering them every three to four sharpenings. Use the flat file with the depth gauge tool laid across the cutters.

Chain tension matters before you file anything. Echo’s guidance is simple: pinch the chain at mid bar. It should pull less than 1/4 inch off the rail, with no sag once released.

Third Party Kits That Fit Echo Chains

Echo’s own kit works fine. Two widely sold third party options cover the same diameters and are just as easy to order.

Mistakes Owners Make

The most common mistake is buying the wrong diameter kit for the saw. A 3/16 inch kit meant for a 0.325 inch pitch farm saw will not touch the cutters correctly on a smaller 3/8 inch low profile homeowner saw, and the reverse is just as common.

The second mistake is trusting the file that ships inside a 2-in-1 tool without checking it against the manual. If the diameters do not match, buy loose files in the correct size rather than forcing an undersized file to work.

The third mistake is skipping depth gauges entirely. A chain that only gets its cutters filed, without the depth gauges ever lowered, cuts slower every time you sharpen it.

When to Move Up to a Grinder

Hand filing works for most homeowners running one or two saws. Owners who sharpen chains often, or who sharpen for other people, tend to move to a bench grinder once they already know the angles by hand.

A grinder is faster and more consistent once set up correctly, but it removes more metal per pass, so a bad setting wastes cutter life quickly. Learn the geometry with a guided file first, then consider a grinder later.

FAQ

What is in the Echo chainsaw sharpener kit?

Echo’s kit includes round files sized to one diameter, a flat file, a file guide, a depth gauge tool, a handle, and a cloth pouch. The exact diameter depends on which of the five part numbers you buy.

Does Echo sell an electric chainsaw sharpener?

Not that Echo lists among its chainsaw accessories. Echo’s sharpening lineup is file kits and replacement files, not a powered tool.

What file size fits my Echo chain?

It depends on your chain’s pitch and gauge, which Echo does not summarize in one public chart. Check the filing reference card in your kit, your owner’s manual, or cross check your chain against a sizing tool before buying.

How often should I lower the depth gauges?

Echo recommends checking and lowering depth gauges every three to four sharpenings, using a flat file with the depth gauge tool from the kit.

How do I know when my Echo chain is dull?

Watch for sawdust instead of chips, having to push the saw, weak cutting at high rpm, a cut pulling to one side, burn marks, slow cuts, or shorter run time on a battery saw.

Can I use a Stihl or Oregon file kit on an Echo chain?

Yes, as long as the file diameter matches your chain’s pitch and gauge. File diameter is a chain specification, not a brand specific one.
