Stihl 28 Chainsaw Guide: 5 Expert Tips for Tough Hardwood

The Stihl 28 chainsaw, while not the largest in the Stihl lineup, is a versatile tool capable of handling a wide range of tasks, especially when properly equipped and operated. However, hardwoods present unique challenges due to their density, grain patterns, and inherent resistance to cutting. Let’s explore the key aspects that will elevate your hardwood cutting game with this particular model.

1. Understanding Your Wood: A Foundation for Success

Before you even fire up your Stihl 28, it’s crucial to understand the properties of the hardwood you’re about to cut. Not all hardwoods are created equal, and their characteristics significantly impact the cutting process.

Wood Anatomy and Properties

Density: Hardwoods, by definition, are denser than softwoods. This means they contain more wood fibers per unit volume, resulting in greater resistance to cutting. Common hardwoods like oak, maple, and hickory have densities ranging from 45 to 70 pounds per cubic foot.
Grain Pattern: The arrangement of wood fibers (grain) influences how easily the wood splits and cuts. Straight-grained hardwoods are generally easier to work with than those with interlocked or wild grain.
Moisture Content: Freshly cut (green) hardwood can have a moisture content of 50% or more. This high moisture content makes the wood heavier and more difficult to cut. Seasoned hardwood, with a moisture content of 12-18%, is significantly easier to process.
Hardness: The Janka hardness test measures the resistance of wood to indentation. Higher Janka ratings indicate harder woods. For example, Brazilian Walnut has a Janka Hardness of 3680 lb compared to American Cherry with a rating of 950 lb. Knowing this will help you understand the resistance your chain will face.

Hardwood vs. Softwood: A Comparative Overview

Feature	Hardwood	Softwood
Density	Higher (generally)	Lower (generally)
Grain Pattern	More varied, can be interlocked	Generally straighter, less complex
Moisture Content	Can be very high when green	Typically lower when green
Hardness	Typically higher Janka Hardness rating	Typically lower Janka Hardness rating
Examples	Oak, Maple, Hickory, Cherry, Walnut	Pine, Fir, Cedar, Spruce
Cutting Ease	More challenging, requires sharper chain	Easier to cut, less demanding on the saw

Practical Implications

Understanding these wood properties allows you to:

Choose the right chain: A chain designed for hardwood will have a more aggressive cutting angle and be made from harder steel.
Adjust your cutting technique: You may need to apply more pressure and cut at a slower pace when dealing with dense, green hardwood.
Anticipate potential problems: Interlocked grain can cause the chain to bind or kickback, requiring extra caution.

2. Chain Selection and Maintenance: The Heart of Efficient Cutting

The chain is the single most important factor in how well your Stihl 28 performs in hardwood. A dull or improperly chosen chain will lead to frustration, inefficiency, and potentially dangerous situations.

Choosing the Right Chain

Chain Type: For hardwoods, I recommend a chain with a chisel or semi-chisel cutter. Chisel chains have a sharper cutting edge and are more efficient in clean wood, but they dull more quickly. Semi-chisel chains are more durable and better suited for dirty or abrasive wood.
Chain Pitch and Gauge: Ensure that the chain pitch and gauge match the specifications of your Stihl 28. Using the wrong chain can damage the saw and compromise safety. (Check your owner’s manual for this specific information.)
Low-Kickback Chains: While low-kickback chains offer increased safety, they can also be less efficient in hardwood. If you are an experienced operator, consider using a standard chain for improved cutting performance, but always prioritize safety.

Chain Sharpening: A Critical Skill

Frequency: Sharpen your chain frequently, ideally after every tank of fuel or whenever you notice a decrease in cutting performance. A sharp chain will cut smoothly and produce large, uniform chips. A dull chain will produce fine dust and require more force to cut.
Tools: Use a chainsaw file, a file guide, and a depth gauge tool. A file guide helps maintain the correct filing angle and depth.
Technique: File each cutter evenly, maintaining the correct angle and depth. Pay attention to the depth gauges, which control the amount of wood the cutter can bite. If the depth gauges are too high, the chain will cut aggressively but be prone to kickback. If they are too low, the chain will cut slowly and produce fine dust.
Professional Sharpening: If you’re not comfortable sharpening your chain yourself, consider taking it to a professional. A properly sharpened chain is a worthwhile investment.

Chain Tension and Lubrication

Tension: Maintain proper chain tension. A loose chain can derail and cause damage, while an overtight chain can overheat and wear prematurely. The chain should be snug against the bar but still able to be pulled around by hand.
Lubrication: Use a high-quality bar and chain oil specifically designed for chainsaws. Ensure that the oiler is functioning correctly and that the chain is receiving adequate lubrication. Insufficient lubrication can cause the chain to overheat and wear rapidly. I’ve found that using a synthetic bar and chain oil can extend the life of the chain and bar, especially when cutting hardwoods.

3. Mastering Cutting Techniques: Precision and Control

Cutting hardwood effectively with a Stihl 28 requires more than just brute force. It demands precision, control, and a thorough understanding of proper cutting techniques.

Felling Techniques (If Applicable)

Tree Assessment: Before felling any tree, carefully assess its lean, branch distribution, and any signs of decay or weakness.
Planning: Plan your escape route and ensure that there are no obstacles in the path of the falling tree.
Notch Cut: Create a notch cut on the side of the tree facing the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
Back Cut: Make a back cut on the opposite side of the tree, slightly above the base of the notch. Leave a hinge of uncut wood to control the direction of the fall.
Wedges: Use wedges to help direct the fall and prevent the saw from binding.
Safety: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, and chainsaw chaps.

Bucking Techniques (Cutting Logs to Length)

Support: Ensure that the log is properly supported to prevent it from pinching the saw. Use logs or wedges to elevate the log off the ground.
Cutting Order: When bucking a log, start by making an undercut about one-third of the way through the log. Then, make an overcut to meet the undercut. This technique prevents the log from splitting and pinching the saw.
Bending Forces: Be aware of bending forces in the log. If the log is supported at both ends, it will be under compression on the top and tension on the bottom. In this case, make the overcut first to relieve the compression. If the log is supported in the middle, it will be under tension on the top and compression on the bottom. In this case, make the undercut first to relieve the tension.
Limbing: When limbing, work from the base of the tree towards the top, keeping the trunk between you and the saw. Use the chainsaw to cut limbs close to the trunk, but avoid damaging the bark.

Avoiding Kickback

Awareness: Kickback occurs when the upper tip of the chainsaw bar comes into contact with an object, causing the saw to suddenly thrust upwards and backwards.
Grip: Maintain a firm grip on the chainsaw with both hands.
Cutting Angle: Avoid cutting with the upper tip of the bar.
Obstacles: Be aware of your surroundings and avoid cutting near obstacles that could cause kickback.
Low-Kickback Chains: Use a low-kickback chain, especially if you are a beginner.

My Personal Experience

I once ignored the signs of tension in a log and attempted to buck it without proper support. The log pinched the saw, causing a violent kickback that nearly resulted in injury. That experience taught me the importance of respecting the forces at play and taking the time to properly support the log before cutting.

4. Optimizing Your Stihl 28: Maximizing Performance

The Stihl 28 is a well-engineered chainsaw, but there are several ways to optimize its performance for cutting tough hardwoods.

Fuel and Oil

Fuel Mixture: Use a high-quality two-stroke oil mixed with gasoline at the ratio specified by Stihl (typically 50:1). Using the wrong fuel mixture can damage the engine. I personally prefer using ethanol-free gasoline to avoid potential fuel system issues.
Bar and Chain Oil: Use a high-quality bar and chain oil specifically designed for chainsaws. Ensure that the oiler is functioning correctly and that the chain is receiving adequate lubrication.

Air Filter Maintenance

Regular Cleaning: Clean the air filter regularly, especially when cutting in dusty conditions. A dirty air filter restricts airflow and reduces engine power.
Replacement: Replace the air filter when it becomes excessively dirty or damaged.

Spark Plug Maintenance

Inspection: Inspect the spark plug regularly for signs of wear or fouling.
Cleaning: Clean the spark plug with a wire brush if necessary.
Replacement: Replace the spark plug according to the manufacturer’s recommendations.

Carburetor Adjustment

Professional Adjustment: If your Stihl 28 is not running smoothly or is lacking power, it may be necessary to adjust the carburetor. This is best done by a qualified technician.
Altitude Adjustment: If you are cutting at a high altitude, you may need to adjust the carburetor to compensate for the thinner air.

Bar Maintenance

Cleaning: Clean the bar regularly to remove sawdust and debris.
Filing: File the bar rails to remove any burrs or damage.
Greasing: Grease the bar sprocket regularly to ensure smooth chain rotation.
Bar Flipping: Flip the bar periodically to ensure even wear.

Case Study: Optimizing Fuel Mixture

In a controlled experiment, I compared the performance of a Stihl 28 using two different fuel mixtures: a standard 50:1 mixture with regular gasoline and a 50:1 mixture with ethanol-free gasoline. The saw was used to cut the same type of hardwood (oak) under identical conditions. The results showed that the saw using ethanol-free gasoline started easier, ran smoother, and produced slightly more power. While the difference was not dramatic, it was noticeable and suggests that using ethanol-free gasoline can provide a slight performance advantage.

5. Safety First: A Non-Negotiable Priority

Chainsaw operation is inherently dangerous, and safety should always be your top priority.

Personal Protective Equipment (PPE)

Helmet: Wear a helmet with a face shield or safety glasses to protect your head and eyes from flying debris.
Hearing Protection: Wear earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
Chainsaw Chaps: Wear chainsaw chaps to protect your legs from accidental cuts.
Gloves: Wear gloves to improve your grip and protect your hands from cuts and abrasions.
Steel-Toed Boots: Wear steel-toed boots to protect your feet from falling logs and other hazards.

Safe Work Practices

Clear Work Area: Clear the work area of obstacles and ensure that you have a safe escape route.
Stable Footing: Maintain stable footing and avoid cutting in awkward positions.
Two-Handed Grip: Always maintain a firm two-handed grip on the chainsaw.
Awareness: Be aware of your surroundings and avoid distractions.
Fatigue: Avoid cutting when you are tired or fatigued.
Alcohol and Drugs: Never operate a chainsaw under the influence of alcohol or drugs.

Emergency Preparedness

First Aid Kit: Keep a well-stocked first aid kit readily available.
Communication: Have a way to communicate with others in case of an emergency.
Emergency Plan: Develop an emergency plan and ensure that everyone on the work site is familiar with it.

Statistics and Data

According to the Consumer Product Safety Commission (CPSC), chainsaws cause approximately 36,000 injuries each year in the United States. A significant percentage of these injuries are preventable through the use of proper PPE and safe work practices. Investing in quality safety gear and taking the time to learn and practice safe techniques is essential for minimizing the risk of injury.

Call to Action

Before you start cutting, take a moment to review your safety procedures and ensure that you have all the necessary safety gear. It’s better to be safe than sorry.
