Husqvarna Chainsaw Sharpening Angles Chart Explained (5 Tips)

Chainsaw sharpening can seem daunting at first, but with a little knowledge and practice, you can master it. This guide focuses specifically on Husqvarna chainsaws, known for their quality and performance. Understanding the correct sharpening angles is crucial for maintaining that performance and extending the life of your chain.

1. Understanding the Importance of Correct Sharpening Angles

Before diving into the specific angles, let’s talk about why they matter. A properly sharpened chainsaw not only cuts faster and more efficiently but also reduces strain on the saw’s engine and minimizes the risk of kickback. Incorrect angles can lead to:

• Slow Cutting: A dull or improperly sharpened chain requires more force, slowing down your progress and wasting energy.
• Increased Wear and Tear: A dull chain puts extra stress on the saw’s engine, potentially leading to premature failure.
• Kickback: Incorrect sharpening can alter the chain’s cutting geometry, increasing the risk of kickback, a dangerous phenomenon where the saw suddenly jumps back towards the operator.
• Uneven Cutting: Incorrect angles can cause the chain to cut unevenly, resulting in crooked cuts and wasted wood.
• Premature Chain Wear: Incorrectly sharpened chains will dull faster, meaning you need to sharpen them more often or replace them sooner.

2. Decoding the Husqvarna Chainsaw Sharpening Angles Chart

Husqvarna chainsaws, like most, have specific angle recommendations for their chains. These angles are typically found in the owner’s manual or on the chain packaging. Here’s a breakdown of the key angles and what they represent:

• Top Plate Angle (Cutting Angle): This is the angle of the top of the cutter tooth relative to the bar. It determines how aggressively the chain bites into the wood. Typically, this angle ranges from 25 to 35 degrees for most Husqvarna chains. A steeper angle (closer to 35 degrees) is more aggressive but may dull faster. A shallower angle (closer to 25 degrees) is less aggressive but stays sharp longer.
• Side Plate Angle (Filing Angle): This is the angle of the side of the cutter tooth relative to the bar. It affects the smoothness of the cut and the amount of wood removed. This angle typically ranges from 60 to 75 degrees for most Husqvarna chains.
• Depth Gauge Setting (Raker Depth): The depth gauge, also known as the raker, controls how much wood the cutter tooth takes with each pass. It’s the small, rounded piece in front of each cutter tooth. The depth gauge setting is crucial for preventing the chain from grabbing too much wood, which can cause kickback and bogging down. The recommended depth gauge setting is typically between 0.025 and 0.030 inches (0.635 to 0.762 mm) for most Husqvarna chains. Always consult your owner’s manual.

Data Point: Studies have shown that maintaining the correct top plate angle can increase cutting efficiency by up to 20%.
