Stihl 028 AV Super: 5 Expert Insights for Saw Enthusiasts
1. Engine and Power Specs: The Heart of the Beast
The Stihl 028 AV Super’s engine is where its legendary reputation begins. It’s a two-stroke engine, which means it needs a mix of gasoline and oil to run properly. Getting this mix wrong is a common mistake I’ve seen, and it can lead to serious engine damage.
- Engine Displacement: Typically around 47.6 cc (cubic centimeters). This figure dictates the engine’s capacity to draw in air and fuel, and the larger the displacement, the more power it can potentially generate.
- Engine Power: Approximately 2.4 kW (kilowatts) or 3.2 bhp (brake horsepower). This is the usable power output at the crankshaft. Don’t underestimate this power; it’s enough for felling small to medium-sized trees and bucking firewood with ease.
- Cylinder Bore: Around 44 mm.
- Piston Stroke: Around 31 mm.
- Fuel Tank Capacity: About 0.5 liters. I always carry extra fuel when working in remote areas. Running out of gas mid-cut is a real pain, and it can also be dangerous, especially if you’re working on an unstable slope.
- Oil Tank Capacity: Approximately 0.27 liters.
- Fuel Mix Ratio: 50:1 (Gasoline: Two-stroke oil). I use a high-quality synthetic two-stroke oil to minimize carbon buildup and ensure smooth engine operation. I also find that pre-mixed fuel options are becoming increasingly popular, offering convenience and accurate ratios.
Expert Insight: I remember one time, I was working with a crew clearing some land for a new development. One of the guys was using a Stihl 028 AV Super, but it was constantly stalling. After checking the usual suspects (spark plug, air filter), I discovered he was using the wrong fuel mix. He thought “more oil is better,” but in reality, too much oil can foul the spark plug and cause the engine to run poorly. Getting the fuel mix right is absolutely crucial for the longevity of your saw.
2. Cutting Equipment: Chain, Bar, and Performance
The cutting equipment is where the rubber meets the road, or rather, where the chain meets the wood. Choosing the right bar and chain combination is essential for optimal performance and safety.
- Recommended Bar Length: Typically ranges from 16 to 20 inches (40 to 50 cm). I find a 18-inch bar to be a good all-around choice for most tasks.
- Chain Pitch: Usually .325 inch. This refers to the distance between three consecutive rivets on the chain.
- Chain Gauge: Typically .050 inch. This is the thickness of the drive links that fit into the bar groove.
- Chain Type: Semi-chisel or full-chisel. Full-chisel chains are sharper and cut faster, but they also dull more quickly and require more frequent sharpening. Semi-chisel chains are more forgiving and better suited for dirty or frozen wood.
- Chain Speed at Max Power: Around 20 m/s (meters per second). This gives you an idea of how quickly the chain is moving when the engine is at full throttle.
Case Study: I once worked on a project clearing a stand of mixed hardwoods and softwoods. We had several different chainsaws, including a Stihl 028 AV Super. We noticed that the saw with the full-chisel chain was cutting through the softwoods like butter, but it was struggling with the hardwoods and dulling quickly. We switched to a semi-chisel chain, and the performance improved significantly, especially in the hardwoods. This highlights the importance of matching the chain type to the type of wood you’re cutting.
Data Point: A study by the US Forest Service found that using a properly sharpened chain can increase cutting efficiency by up to 20%.
3. Physical Dimensions and Weight: Handling and Ergonomics
The physical dimensions and weight of the chainsaw affect its handling and ergonomics, which are important considerations for comfort and safety, especially during long periods of use.
- Weight (without bar and chain): Approximately 5.6 kg (12.3 lbs). This is a manageable weight for most users, but it can still be tiring to use for extended periods.
- Overall Length (with 18-inch bar): Around 85 cm (33.5 inches).
- Handle Design: The Stihl 028 AV Super features an anti-vibration (AV) system to reduce operator fatigue. This is a crucial feature, especially if you’re using the saw for several hours at a time.
- Ergonomic Considerations: The saw’s balance and handle placement contribute to its overall ease of use. I always recommend wearing proper gloves to improve grip and reduce vibration.
Personal Story: I’ve seen firsthand how important ergonomics are. A friend of mine, who was new to chainsaw work, tried to save a few bucks by buying a cheap, poorly designed saw. After just a few hours of use, he developed severe hand and arm fatigue, and he even had to take time off work to recover. Investing in a well-designed chainsaw with good ergonomics is worth it in the long run, both for your comfort and your safety.
4. Safety Features: Protecting the Operator
Safety should always be the top priority when operating a chainsaw. The Stihl 028 AV Super incorporates several safety features to protect the operator.
- Chain Brake: This is a crucial safety feature that stops the chain almost instantly in case of kickback. I always check the chain brake before starting the saw to make sure it’s working properly.
- Throttle Lock: Prevents accidental acceleration.
- Chain Catcher: Catches the chain if it breaks or comes off the bar.
- Hand Guard: Protects the operator’s hand from flying debris.
- Anti-Vibration System: Reduces operator fatigue and the risk of vibration-related injuries.
Safety Codes & Standards: Always adhere to local safety codes and regulations when operating a chainsaw. These regulations may vary depending on your location. In the US, OSHA (Occupational Safety and Health Administration) provides guidelines for chainsaw safety. In Europe, the EN (European Norm) standards apply.
Best Practices:
- Always wear appropriate personal protective equipment (PPE), including a helmet, eye protection, hearing protection, gloves, chainsaw chaps, and sturdy boots.
- Never operate a chainsaw when you’re tired or under the influence of drugs or alcohol.
- Maintain a safe working distance from other people.
- Be aware of your surroundings and potential hazards, such as overhead power lines or unstable ground.
Technical Limitation: The chain brake is only effective if it’s properly maintained. I recommend cleaning and lubricating the chain brake mechanism regularly to ensure it functions correctly.
5. Maintenance and Troubleshooting: Keeping Your Saw in Top Condition
Regular maintenance is essential for keeping your Stihl 028 AV Super running smoothly and prolonging its lifespan. Neglecting maintenance can lead to performance issues and costly repairs.
- Air Filter: Clean the air filter regularly, especially when working in dusty conditions. A dirty air filter can restrict airflow and cause the engine to run poorly.
- Spark Plug: Check the spark plug regularly and replace it if necessary. A fouled spark plug can cause the engine to misfire or not start at all.
- Fuel Filter: Replace the fuel filter periodically to prevent debris from entering the carburetor.
- Chain Sharpening: Sharpen the chain regularly to maintain optimal cutting performance. A dull chain is not only less efficient, but it’s also more dangerous.
- Bar Lubrication: Ensure the bar is properly lubricated to prevent wear and tear. I use a high-quality bar and chain oil.
- Carburetor Adjustment: The carburetor may need to be adjusted periodically to ensure the engine is running properly. If you’re not comfortable adjusting the carburetor yourself, take the saw to a qualified service technician.
Tool Requirements:
- Spark plug wrench
- Screwdriver
- File for chain sharpening
- Grease gun for bar lubrication
Troubleshooting Common Issues:
- Engine won’t start: Check the fuel level, spark plug, air filter, and fuel filter.
- Engine stalls: Check the fuel mix, air filter, and carburetor adjustment.
- Chain dulls quickly: Check the chain tension, bar lubrication, and wood type.
- Excessive vibration: Check the anti-vibration system and chain tension.
Original Research: In my own experience, I’ve found that using a fuel stabilizer in the gasoline can help prevent fuel-related problems, especially when storing the chainsaw for extended periods. Fuel stabilizers prevent the fuel from breaking down and forming gummy deposits in the carburetor.
Data Point: According to Stihl, regular maintenance can extend the lifespan of a chainsaw by up to 50%.
