How to Use Oregon Chainsaw Sharpener (5 Pro Tips for Stihl Chains)

Understanding the Basics: Why a Sharp Chain Matters

Before we get into the specifics of using the Oregon chainsaw sharpener, let’s establish why a sharp chain is so important.

• Safety: A sharp chain cuts smoothly and predictably. A dull chain, on the other hand, can “kickback,” causing the saw to jump back towards you, a leading cause of chainsaw injuries.
• Efficiency: A sharp chain cuts faster and requires less effort, reducing fatigue and increasing productivity. I’ve found I can cut twice as much wood with a sharp chain compared to a dull one in the same amount of time and with significantly less strain on my body.
• Chainsaw Longevity: A dull chain puts unnecessary stress on your chainsaw’s engine and bar, leading to premature wear and tear. Sharpening your chain regularly extends the life of your saw.
• Wood Quality: A sharp chain produces cleaner cuts, which is especially important if you’re milling lumber or using the wood for aesthetic purposes. No one wants splintered, ragged edges on their projects.

Key Terms:

• Green Wood: Freshly cut wood with a high moisture content. Generally easier to cut but more prone to warping and cracking as it dries.
• Seasoned Wood: Wood that has been dried to a lower moisture content, typically 20% or less. Harder to cut but more stable and burns more efficiently.
• Raker (Depth Gauge): The small projection in front of each cutting tooth that controls the depth of the cut.
• Cutting Tooth: The part of the chain that actually does the cutting.
• Chain Pitch: The distance between three consecutive rivets on the chain, divided by two.
• Chain Gauge: The thickness of the drive links that fit into the bar groove.

Pro Tip #1: Choosing the Right Oregon Chainsaw Sharpener

The Oregon brand offers a range of chainsaw sharpeners, from basic hand-held files to more sophisticated electric models. For Stihl chains, I recommend considering these options:

• Oregon 511AX Bench Chain Grinder: This electric grinder is ideal for those who sharpen chains frequently. It provides consistent and accurate sharpening. In my experience, the initial investment is worth it if you’re processing a lot of wood.
• Oregon 23736 Saw Chain Filing Kit: This kit includes a round file, a flat file, and a filing guide. It’s a good option for occasional sharpening and for touching up your chain in the field.
• Oregon Sure Sharp Hand Held Chainsaw Sharpener: A simple, easy-to-use tool for quick sharpening. Good for beginners, but not as precise as other methods.

My Personal Story: I started with a basic hand-held file, and while it worked, I found it time-consuming and difficult to get consistent results. After investing in an Oregon 511AX grinder, the difference was night and day. My chains were sharper, lasted longer, and I spent significantly less time sharpening.

Data Point: According to Oregon’s product specifications, the 511AX can sharpen a chain in as little as 2-3 minutes, compared to 15-20 minutes with a hand file.

Choosing the Right File Size:

The correct file size is crucial for effective sharpening. Stihl chains come in various sizes, so you’ll need to match the file size to the chain pitch. Here’s a general guideline:

• Chain Pitch 3/8″ Low Profile (.375″): Use a 5/32″ (4.0 mm) file
• Chain Pitch .325″: Use a 3/16″ (4.8 mm) file
• Chain Pitch 3/8″ (.375″): Use a 5/32″ (5.5 mm) file
• Chain Pitch .404″: Use a 7/32″ (5.5 mm) file

How to Determine Your Chain Pitch:

The chain pitch is usually stamped on the chainsaw bar near the mounting point. You can also measure the distance between three consecutive rivets and divide by two.

Pro Tip #2: Mastering the Hand Filing Technique

While electric grinders are great, knowing how to hand file your chain is an essential skill, especially for field maintenance. Here’s a step-by-step guide:

1. Secure the Chainsaw: Clamp the chainsaw in a vise or use a stump vise to hold it securely. Make sure the chain is easily accessible.
2. Identify the Cutting Angle: Stihl chains typically have a cutting angle of 30-35 degrees. Use a filing guide to maintain this angle.
3. Position the File: Place the round file in the gullet of the cutting tooth, ensuring the file is at the correct angle. The filing guide should rest on top of the chain.
4. File with Smooth Strokes: Push the file forward and slightly upward, following the contour of the cutting tooth. Use smooth, even strokes. Avoid pressing too hard, as this can damage the file and the chain.
5. Count Your Strokes: File each tooth with the same number of strokes to ensure consistent sharpening. I usually use 3-5 strokes per tooth.
6. Check Your Work: After filing a few teeth, check your work. The cutting edge should be sharp and even.
7. Repeat for All Teeth: Rotate the chain and repeat the process for all the cutting teeth on one side of the chain. Then, flip the saw and repeat for the teeth on the other side.
8. File the Rakers: Use a flat file and a raker gauge to file down the rakers (depth gauges). The raker gauge will indicate how much material to remove. This is crucial for controlling the depth of the cut.
9. Clean the Chain: After sharpening, clean the chain with a brush to remove any metal filings.
10. Lubricate the Chain: Apply chain oil to lubricate the chain before using the chainsaw.

My Personal Experience: I once neglected to file the rakers after sharpening my chain. The result was that the chain wouldn’t bite into the wood properly, and the saw vibrated excessively. Filing the rakers made a huge difference.

Tool Specifications:

• Round File: Nicholson 5/32″ chainsaw file
• Flat File: Bahco 8″ bastard file
• Filing Guide: Oregon 25894 filing guide
• Raker Gauge: Stihl raker gauge

Strategic Advantage: Hand filing allows you to sharpen your chain in the field, minimizing downtime. It’s also a more affordable option than using an electric grinder.

Pro Tip #3: Using an Oregon Electric Chainsaw Sharpener

An electric chainsaw sharpener like the Oregon 511AX offers precision and speed. Here’s how to use it effectively:
