The Stihl 028 Super. For many of us in the wood processing world, the name alone conjures images of hard work, reliability, and the satisfying scent of freshly cut wood. But beyond its reputation, the 028 Super holds hidden benefits – untapped potential waiting to be unleashed. It’s not just about cutting wood; it’s about efficiency, precision, and minimizing strain. This guide isn’t just another chainsaw review; it’s a deep dive into optimizing your 028 Super, drawing on years of personal experience and insights from fellow loggers. I’ll share my best-kept secrets to get the most out of this iconic machine.
1. Precision Sharpening: The Cornerstone of Efficient Cutting
The sharpness of your chain is arguably the most crucial factor in chainsaw performance. A dull chain forces the saw to work harder, increasing fuel consumption, wear and tear, and operator fatigue. I’ve seen firsthand how a meticulously sharpened chain can transform the 028 Super from a struggling workhorse into a smooth, efficient cutting machine.
Mastering the Art of Chain Sharpening
Sharpening isn’t just about filing the teeth. It’s about maintaining the correct angles and depth gauges. Here’s my step-by-step approach:
- Secure the Saw: Use a vise or a stump vise to firmly hold the saw in place. This provides stability and accuracy.
- Choose the Right File: For the 028 Super, I recommend a 5/32″ round file for the cutting teeth and a flat file for the depth gauges.
- Maintain the Correct Angle: The file should be held at a 30-degree angle relative to the cutter, following the existing angle of the tooth. Use a filing guide for consistent results.
- Consistent Strokes: Use smooth, even strokes, filing each tooth the same number of times (usually 3-5 strokes).
- Depth Gauge Adjustment: After sharpening the teeth, use a depth gauge tool to ensure the depth gauges are properly set. I typically aim for a depth of 0.025″ to 0.030″ for hardwood and slightly deeper for softwood.
- Raker Adjustment: Correctly adjusted rakers are essential for efficient chip removal.
Personal Story: I remember one particular job cutting seasoned oak. My chain was slightly dull, and I was struggling to make clean cuts. After taking the time to sharpen the chain properly, the difference was night and day. The saw sliced through the oak with ease, saving me time and energy.
Actionable Metric: Track your chain sharpening frequency. I aim to sharpen my chain after every 2-3 tanks of fuel, or sooner if I notice a decrease in cutting performance.
Takeaway: Sharpness isn’t just about speed; it’s about safety and efficiency. A sharp chain reduces the risk of kickback and ensures clean, controlled cuts.
2. Optimizing Fuel Mixture and Carburetor Tuning
The 028 Super, like many older chainsaws, relies on a precise fuel mixture for optimal performance. Using the wrong mixture can lead to poor performance, engine damage, and a shortened lifespan. I’ve seen firsthand the devastating effects of neglecting this crucial aspect of chainsaw maintenance.
The Perfect Fuel Blend
- Fuel Type: Always use high-quality gasoline with an octane rating of 89 or higher.
- Oil Type: Use a high-quality two-stroke oil specifically designed for air-cooled engines. Stihl’s own Ultra HP oil is a reliable choice.
- Mixing Ratio: The recommended mixing ratio for the 028 Super is typically 50:1 (gasoline to oil). Always refer to your owner’s manual for the specific recommendation.
- Mixing Procedure: Pour the correct amount of oil into a clean fuel container first, then add the gasoline. Shake well to ensure thorough mixing.
Carburetor Tuning: Fine-Tuning for Peak Performance
The carburetor controls the air-fuel mixture entering the engine. Proper carburetor tuning is essential for smooth idling, responsive acceleration, and optimal power output.
- Locate the Adjustment Screws: The carburetor has three adjustment screws: L (low-speed), H (high-speed), and LA (idle speed).
- Initial Settings: Start with the manufacturer’s recommended settings (typically 1 turn out from fully closed for both L and H screws).
- Idle Adjustment: Turn the LA screw until the engine idles smoothly without stalling.
- Low-Speed Adjustment: Adjust the L screw for smooth acceleration from idle.
- High-Speed Adjustment: Adjust the H screw for optimal power output at full throttle. Use a tachometer to ensure the engine is not over-revving. The maximum recommended RPM for the 028 Super is around 12,500 RPM.
- Listen Carefully: Pay close attention to the engine’s sound. A lean mixture (too much air) will cause the engine to run hot and potentially damage it. A rich mixture (too much fuel) will cause the engine to smoke excessively and lose power.
Original Insight: I’ve found that environmental factors, such as altitude and temperature, can significantly affect carburetor performance. At higher altitudes, the air is thinner, requiring a leaner mixture. In colder temperatures, a slightly richer mixture may be necessary for easier starting.
Real-World Example: I once worked on a logging site at an elevation of 7,000 feet. The chainsaws were running poorly, lacking power and stalling frequently. After adjusting the carburetors for the higher altitude, the saws ran flawlessly.
Takeaway: Proper fuel mixture and carburetor tuning are essential for maximizing the performance and lifespan of your 028 Super. Don’t be afraid to experiment and fine-tune the settings to suit your specific conditions.
3. Bar and Chain Maintenance: Extending the Life of Your Cutting System
The bar and chain are the heart of your chainsaw’s cutting system. Neglecting their maintenance can lead to premature wear, reduced cutting efficiency, and even dangerous situations. I’ve learned the hard way that a little preventative maintenance goes a long way in extending the life of these critical components.
Bar Maintenance: Preventing Wear and Tear
- Regular Cleaning: Clean the bar groove and oil holes regularly to ensure proper lubrication. Use a bar groove cleaner or a small screwdriver to remove debris.
- Bar Rail Dressing: Use a bar rail dressing tool to remove burrs and restore the square edges of the bar rails. This helps maintain chain stability and prevents uneven wear.
- Bar Rotation: Rotate the bar periodically (every few days of use) to distribute wear evenly.
- Bar Inspection: Inspect the bar for damage, such as cracks, bends, or excessive wear. Replace the bar if necessary.
- Oiling System Check: Ensure the oiler is functioning properly. A lack of lubrication will quickly destroy the bar and chain.
Chain Maintenance: Keeping Your Chain in Top Condition
- Chain Tension: Maintain proper chain tension. A loose chain can derail easily, while an overly tight chain can cause excessive wear on the bar and chain.
- Chain Lubrication: Use a high-quality bar and chain oil. I prefer a vegetable-based oil, as it is more environmentally friendly.
- Chain Sharpening (Revisited): As mentioned earlier, a sharp chain is essential for efficient cutting and reduced wear.
- Chain Inspection: Inspect the chain for damage, such as broken teeth, loose rivets, or excessive wear. Replace the chain if necessary.
Case Study: I once worked on a project where we were cutting a large quantity of firewood. One of the saws was experiencing frequent chain derailments. After inspecting the bar, I discovered that the bar rails were severely worn. Replacing the bar solved the problem and improved the saw’s cutting performance significantly.
Actionable Metric: Check your chain tension before each use. The chain should be snug against the bar but still able to be pulled around by hand.
Takeaway: Regular bar and chain maintenance is crucial for maximizing the lifespan and performance of your cutting system. A little effort can save you a lot of money and frustration in the long run.
