Understanding Your Chainsaw Chain and Sharpener

Before diving into the sharpening process, it’s crucial to understand the key components of your chainsaw chain and the sharpener itself. This foundational knowledge will allow you to make informed decisions and achieve optimal results.

Key Chainsaw Chain Components:

• Cutters (Teeth): These are the cutting edges of the chain. Each cutter has a top plate cutting angle, a side plate cutting angle, and a depth gauge (raker).
• Depth Gauges (Rakers): These control the depth of the cut each cutter takes. They sit slightly lower than the cutters.
• Tie Straps: These connect the cutters and drive links.
• Drive Links: These fit into the chainsaw’s drive sprocket, propelling the chain around the bar.
• Rivets: These hold all the components together.

Key Oregon Chainsaw Sharpener Components:

There are several types of Oregon chainsaw sharpeners: file guides, electric sharpeners, and grinder sharpeners. I will focus on the commonly used file guide and electric sharpeners.

• File Guide (For Manual Sharpening): This tool helps maintain the correct filing angle and depth. It usually consists of a frame, file, and markings for angle adjustment.
• Round File: This is the tool that actually sharpens the cutters. The size of the file must match the pitch of your chain (more on this later).
• Flat File: Used to adjust the depth gauges (rakers).
• Depth Gauge Tool (Raker Gauge): This tool ensures the depth gauges are set to the correct height.
• Electric Sharpener: This uses a grinding wheel to sharpen the cutters. They typically have adjustable angles and depth settings.
• Grinding Wheel: The abrasive wheel that sharpens the cutters on an electric sharpener. Different grits are available for different levels of sharpening.
• Clamping Mechanism: Holds the chain securely in place while sharpening with an electric sharpener.
• Angle Adjustment: Allows you to set the correct sharpening angle for your chain.
• Depth Adjustment: Controls how much material is removed from the cutter during sharpening.

Key Concepts:

• Chain Pitch: The distance between three consecutive rivets divided by two. This determines the size of the round file you need. Common pitches include .325″, 3/8″, and .404″.
• Gauge: The thickness of the drive links, which must match the bar groove width. Common gauges include .043″, .050″, .058″, and .063″.
• Filing Angle: The angle at which you file the cutters. This is typically marked on the file guide or electric sharpener.
• Depth Gauge Setting: The height of the depth gauges relative to the cutters. This affects the aggressiveness of the cut.
• Top Plate Angle: The angle of the top plate of the cutter. This is usually pre-set on the chain and should be maintained during sharpening.
• Side Plate Angle: The angle of the side plate of the cutter. This is also usually pre-set and should be maintained.

Knowing these components and concepts is the first step towards achieving precise cuts. It allows you to understand what you are doing and why, leading to more effective and efficient sharpening.

Tip 4: Fine-Tuning Depth Gauges (Rakers) for Optimal Cutting Performance

The depth gauges, or rakers, play a critical role in determining how aggressively your chainsaw cuts. Properly adjusted depth gauges ensure that each cutter takes the correct size bite of wood, resulting in smooth and efficient cutting. Neglecting the depth gauges can lead to a chain that chatters, vibrates excessively, or simply doesn’t cut well.

Understanding Depth Gauge Function:

The depth gauge sits slightly lower than the cutter and controls the amount of wood the cutter can remove in a single pass. If the depth gauge is too high (not filed down enough), the cutter will not be able to engage the wood effectively, resulting in a slow and inefficient cut. If the depth gauge is too low (filed down too much), the cutter will take too large of a bite, causing the chain to grab, chatter, and vibrate excessively.

Step-by-Step Guide to Depth Gauge Adjustment:

1. Clean the Chain: Before adjusting the depth gauges, clean the chain thoroughly to remove any dirt, sawdust, or debris. This will ensure accurate measurements.
2. Use a Depth Gauge Tool: Place the depth gauge tool on the chain, aligning it with the depth gauge you want to adjust. The tool will have a slot or opening that allows you to see how much the depth gauge protrudes.
3. File the Depth Gauge: If the depth gauge protrudes above the tool, use a flat file to file it down until it is flush with the tool. Use smooth, even strokes and avoid applying excessive pressure.
4. Round Off the Front Edge: After filing the depth gauge, use the flat file to round off the front edge. This prevents the depth gauge from digging into the wood and causing the chain to chatter.
5. Repeat for All Depth Gauges: Move the depth gauge tool to the next depth gauge and repeat the filing and rounding process. Be sure to adjust all depth gauges on the chain.
6. Check for Consistency: After adjusting all the depth gauges, check for consistency. All depth gauges should be the same height and have a rounded front edge.

Key Considerations:

• Depth Gauge Setting: The correct depth gauge setting depends on the type of wood you are cutting and the condition of the chain. Softer woods typically require a lower depth gauge setting (more aggressive cut), while harder woods require a higher setting (less aggressive cut). A new chain typically requires a slightly higher setting than a worn chain. Consult your chainsaw’s manual or the chain manufacturer’s recommendations for the optimal setting.
• Depth Gauge Tool: Use a depth gauge tool specifically designed for your chain type and pitch. This will ensure accurate and consistent settings.
• Filing Technique: Use a smooth and even filing technique to avoid creating flat spots or sharp edges on the depth gauges.
