These five “pro hacks” are based on my experience and will help you keep your saw running smoothly.

1. Master the Art of Chain Sharpening

A sharp chain is the heart of an efficient chainsaw. A dull chain not only cuts slower but also puts unnecessary strain on the engine, leading to premature wear and tear. I’ve seen loggers struggle all day with a dull chain, wasting time and fuel, when a few minutes of sharpening could have made all the difference.

Why Sharpening Matters

Increased Cutting Speed: A sharp chain slices through wood effortlessly, reducing cutting time.
Reduced Strain on Engine: A sharp chain requires less power to cut, prolonging engine life.
Improved Safety: A sharp chain is less likely to kickback, reducing the risk of injury.
Cleaner Cuts: A sharp chain produces smoother, more precise cuts.

Sharpening Tools You’ll Need

Chainsaw File: Use a file specifically designed for chainsaw chains. The correct size is crucial. For most Husqvarna 36-inch chainsaws, a 5/32″ or 7/32″ file is common, but always check your chain’s specifications.
File Guide: A file guide helps maintain the correct angle and depth during sharpening.
Depth Gauge Tool: This tool is used to adjust the depth gauges (rakers) on the chain.
Vise: A small vise to hold the chainsaw bar securely while sharpening.
Gloves: To protect your hands.

Step-by-Step Sharpening Guide

Secure the Chainsaw: Place the chainsaw in a vise or clamp the bar securely to a workbench. Make sure the chain is free to move.
Identify the Correct Angle: Most chainsaw chains have markings indicating the correct sharpening angle. If not, consult your chainsaw’s manual or the chain manufacturer’s specifications. Typically, it’s around 30 degrees.
Position the File: Place the file guide on the chain so that the file sits at the correct angle.
Sharpen Each Cutter: Using smooth, even strokes, file each cutter from the inside out. Apply light pressure on the forward stroke and release on the return stroke. Count the number of strokes you use on each cutter and repeat the same number on all the others to ensure consistent sharpening. Typically, 3-5 strokes per cutter are sufficient.
Check for Burr: After sharpening each cutter, check for a small burr on the edge. If present, remove it with a fine file or a honing stone.
Adjust Depth Gauges (Rakers): After sharpening the cutters several times, the depth gauges (rakers) may need to be adjusted. Use a depth gauge tool to check the height of the rakers. If they are too high, file them down until they are flush with the tool. Consult your chainsaw’s manual for the correct depth gauge setting.
Rotate the Chain: Advance the chain and repeat the sharpening process on each cutter.
Inspect and Clean: Once you’ve sharpened all the cutters, inspect the chain for any damage or wear. Clean the chain with a brush and apply chain oil.

Pro Tips for Sharpening

Maintain Consistent Angle: Use a file guide to ensure a consistent sharpening angle. This is critical for even cutting.
Don’t Over-Sharpen: Over-sharpening can weaken the chain and reduce its lifespan.
Sharpen Regularly: Sharpen the chain after every few hours of use, or whenever you notice a decrease in cutting performance.
Use a Chainsaw Sharpener: For more precise and consistent sharpening, consider using a chainsaw sharpener. These tools can be electric or manual and are available in a variety of styles and price ranges.

Case Study: Sharpening for Efficiency

I once worked on a logging project where the crew was struggling to meet their daily quota. After observing their work, I noticed that their chains were dull and they were forcing the saws through the wood. I spent an afternoon teaching them proper sharpening techniques and providing them with the necessary tools. The next day, their production increased by 25%, and they were able to meet their quota with ease. This simple change had a significant impact on their efficiency and profitability.

2. The Fuel Factor: Optimizing Your Mix

The fuel you use in your Husqvarna 36-inch chainsaw is just as important as the chain. Using the wrong fuel or an improper fuel mixture can lead to poor performance, engine damage, and a shortened lifespan. I’ve seen countless engines ruined by using old fuel or the wrong oil mixture.

Understanding Fuel Requirements

Octane Rating: Husqvarna recommends using gasoline with a minimum octane rating of 89 (AKI) or 95 (RON). Using lower octane fuel can cause engine knocking and damage.
Ethanol Content: Ethanol is an alcohol added to gasoline. While it can improve octane, it can also absorb water, which can cause corrosion and fuel system problems. Husqvarna recommends using fuel with an ethanol content of no more than 10% (E10). Avoid using fuel with higher ethanol content (e.g., E85).
Fuel Stabilizer: If you’re not going to use the chainsaw for an extended period, add a fuel stabilizer to the gasoline. This will prevent the fuel from breaking down and causing problems.

The Importance of Oil Mix

Two-Stroke Oil: Chainsaws use two-stroke engines, which require oil to be mixed with the gasoline. This oil lubricates the engine’s internal components.
Oil Ratio: Husqvarna specifies a specific oil ratio for their chainsaws. For most models, including the 36-inch, the recommended ratio is 50:1 (50 parts gasoline to 1 part oil). Using the wrong oil ratio can cause engine damage. Too little oil can lead to insufficient lubrication, while too much oil can cause carbon buildup and poor performance.
Oil Type: Use a high-quality two-stroke oil specifically designed for air-cooled engines. Husqvarna recommends using their own brand of oil, but other reputable brands are also acceptable.

Mixing Fuel and Oil Correctly

Use Fresh Gasoline: Use fresh gasoline that is no more than 30 days old. Old gasoline can break down and cause problems.
Measure Accurately: Use a measuring container to accurately measure the gasoline and oil. Don’t guess!
Mix Thoroughly: Pour the gasoline and oil into a fuel can and shake vigorously for at least 30 seconds to ensure they are thoroughly mixed.
Label the Can: Label the fuel can with the date and the oil ratio. This will help you keep track of how old the fuel is and prevent you from using the wrong mixture in your chainsaw.

Pro Tips for Fuel Management

Use Premium Fuel: Consider using premium gasoline with a higher octane rating. This can improve engine performance and reduce the risk of engine knocking.
Store Fuel Properly: Store gasoline in a clean, airtight container in a cool, dry place. Avoid storing gasoline in direct sunlight or near sources of heat.
Drain Fuel Before Storage: If you’re not going to use the chainsaw for an extended period, drain the fuel tank and carburetor. This will prevent the fuel from breaking down and causing problems.
Use Pre-Mixed Fuel: For convenience and peace of mind, consider using pre-mixed fuel. These fuels are formulated to meet the specific requirements of two-stroke engines and are often ethanol-free.

Case Study: The Perils of Bad Fuel

I once diagnosed a chainsaw that was running poorly and had difficulty starting. After inspecting the engine, I discovered that the fuel tank was full of old, gummy gasoline. The owner had stored the chainsaw for several months without draining the fuel, and the gasoline had broken down and clogged the carburetor. I had to completely disassemble and clean the carburetor to get the chainsaw running properly again. This experience taught me the importance of using fresh fuel and storing chainsaws properly.

Takeaway: Using the correct fuel and oil mixture is critical for the performance and longevity of your Husqvarna 36-inch chainsaw. Use fresh gasoline with the correct octane rating and ethanol content, mix it with high-quality two-stroke oil at the recommended ratio, and store fuel properly. This will help you avoid engine problems and keep your chainsaw running smoothly for years to come.
