I’m going to share my top 5 pro tips for getting the most out of your Stihl 028 AV Super, ensuring it performs optimally for years to come.

1. Fuel and Oil: The Lifeblood of Your 028 AV Super

Just like a fine-tuned engine needs the right fuel, your Stihl 028 AV Super thrives on a precise mixture of gasoline and two-stroke oil. This isn’t just a suggestion; it’s a fundamental requirement for its longevity and performance. I can’t stress this enough: always use a high-quality, two-stroke oil specifically formulated for air-cooled engines.

Why is this so critical?

Two-stroke engines, unlike their four-stroke counterparts, rely on the fuel mixture to lubricate the piston, cylinder, and other vital internal components. Skimping on oil or using the wrong type can lead to catastrophic engine failure. I’ve seen it happen firsthand, and it’s not pretty (or cheap to fix!).

The Right Mix:

Stihl recommends a 50:1 fuel-to-oil ratio for the 028 AV Super. This means 50 parts gasoline to 1 part oil. Using pre-mixed fuel is a convenient option, ensuring the correct ratio every time. However, mixing your own allows you to control the quality of both the fuel and the oil.

Gasoline: Use fresh, high-octane gasoline (89 octane or higher). Avoid using gasoline that has been sitting for extended periods, as it can degrade and gum up the carburetor.
Two-Stroke Oil: Opt for a synthetic or semi-synthetic two-stroke oil designed for air-cooled engines. These oils provide superior lubrication and burn cleaner, reducing carbon buildup. Stihl Ultra HP is a popular and reliable choice.

My Personalized Story:

I remember one particularly cold winter, I decided to cut corners and use some old gasoline that had been sitting in my shed for months. Big mistake! The 028 AV Super sputtered, coughed, and eventually refused to start. After a frustrating afternoon of troubleshooting, I realized the fuel was the culprit. I drained the tank, refilled it with fresh gas and the correct oil mixture, and the saw roared back to life. Lesson learned: Don’t underestimate the importance of quality fuel and oil.

Data Points and Statistics:

Studies have shown that using low-quality two-stroke oil can reduce engine lifespan by up to 50%.
Fuel degradation can occur in as little as 30 days, leading to poor engine performance and potential damage.
Using the correct fuel-to-oil ratio can improve fuel efficiency by up to 10%.

Actionable Takeaways:

Always use fresh, high-octane gasoline and high-quality two-stroke oil.
Mix your fuel and oil in the correct ratio (50:1).
Store fuel in a clean, airtight container and use it within 30 days.
Consider using fuel stabilizer if you plan to store fuel for longer periods.

2. Sharpening Your Chain: The Key to Efficient Cutting

A dull chainsaw is not only inefficient but also dangerous. It forces you to apply more pressure, increasing the risk of kickback and fatigue. A sharp chain, on the other hand, slices through wood with ease, making your work faster, safer, and more enjoyable.

Understanding Chain Sharpening:

Chainsaw chains are designed with cutting teeth that have specific angles and depths. Over time, these teeth become dull due to friction and contact with dirt, rocks, and other debris. Sharpening restores the correct angles and depths, allowing the chain to cut efficiently.

Tools of the Trade:

Round File and File Guide: This is the most common and versatile method for sharpening chainsaw chains. A round file is used to sharpen the cutting teeth, while a file guide helps maintain the correct angles and depth.
Flat File and Depth Gauge Tool: A flat file is used to adjust the depth gauges, which control the amount of wood each tooth can cut. A depth gauge tool ensures that all the depth gauges are set to the correct height.
Chain Grinder: This is a power tool that uses a grinding wheel to sharpen chainsaw chains quickly and accurately. It’s a good option for those who sharpen chains frequently or who want a more precise sharpening.

The Sharpening Process (Using a Round File and File Guide):

Secure the Chain: Clamp the chainsaw bar in a vise or use a chain vise to hold the chain securely.
Identify the Correct File Size: The correct file size will depend on the chain pitch (the distance between the rivets on the chain). Refer to your chainsaw’s manual or the chain manufacturer’s recommendations.
Position the File Guide: Place the file guide on the chain, aligning the arrows with the direction of chain rotation.
Sharpen Each Tooth: Using smooth, even strokes, file each cutting tooth from the inside out. Maintain the correct angle and depth as indicated by the file guide.
Check the Depth Gauges: Use a depth gauge tool to check the height of the depth gauges. If they are too high, use a flat file to lower them to the correct height.
Repeat for All Teeth: Sharpen all the cutting teeth on the chain, ensuring that they are all sharpened to the same length and angle.

My Personalized Story:

I used to dread sharpening my chainsaw chain. I found it tedious and time-consuming, and I never seemed to get it quite right. But then I took a chainsaw maintenance course at a local community college, and it completely changed my perspective.
