Pro Logging Tip #1: Chainsaw Maintenance – The Key to Longevity

A well-maintained chainsaw is a safe chainsaw, and a productive chainsaw. This isn’t just about keeping it running; it’s about maximizing its lifespan and preventing costly repairs.

Understanding the Basics

Air Filter: A clean air filter is critical for engine performance. A dirty filter restricts airflow, leading to reduced power and increased fuel consumption.
- Action: Clean the air filter after every 8 hours of use, or more frequently in dusty conditions. Use compressed air or warm soapy water to remove debris. Replace the filter annually, or as needed.
Spark Plug: A faulty spark plug can cause hard starting, misfires, and poor engine performance.
- Action: Inspect the spark plug regularly for wear and carbon buildup. Clean or replace the spark plug as needed. Consult your Stihl AV 038 owner’s manual for the correct spark plug type and gap.
Fuel Filter: A clogged fuel filter restricts fuel flow, leading to engine stalling and poor performance.
- Action: Replace the fuel filter annually.
Chain Lubrication: Proper chain lubrication is essential for smooth cutting and preventing premature wear of the chain and bar.
- Action: Use a high-quality bar and chain oil. Check the oil level frequently and adjust the oiler output as needed. A good rule of thumb is that you should see a light spray of oil coming off the chain while cutting.
Chain Tension: Correct chain tension is crucial for safe and efficient cutting. A loose chain can derail, while a tight chain can bind and overheat.
- Action: Check chain tension before each use. The chain should be snug against the bar but still able to be pulled around by hand. Adjust the tension as needed.
Sharpening the Chain: A sharp chain is a safe chain. A dull chain requires more force to cut, increasing the risk of kickback.
- Action: Sharpen the chain regularly using a chainsaw file or a chain grinder. Maintain the correct filing angle and depth gauge settings.

Deep Dive: Chain Sharpening Techniques

Sharpening a chainsaw chain is an art form. There are several methods, each with its own advantages and disadvantages.

Hand Filing: This is the most common method and requires a round file, a flat file (for depth gauges), and a filing guide.
- Pros: Portable, inexpensive, allows for precise control.
- Cons: Requires practice and skill, can be time-consuming.
- Technique: Secure the chainsaw in a vise. Use the round file to sharpen each cutter, maintaining the correct angle and depth. Use the flat file to adjust the depth gauges as needed. The angle is typically 30 degrees, but check your chain manufacturer’s specifications.
Chain Grinder: This is a faster and more precise method, but it requires a specialized machine.
- Pros: Fast, precise, consistent results.
- Cons: Expensive, requires a power source, less portable.
- Technique: Follow the manufacturer’s instructions for your chain grinder. Ensure that the chain is properly aligned and that the grinding wheel is set to the correct angle and depth.
On-Saw Sharpeners: These sharpeners attach directly to your chainsaw and use a grinding stone to sharpen the chain while it’s on the bar.
- Pros: Convenient, relatively inexpensive.
- Cons: Can be less precise than other methods, may not be suitable for all chains.
- Technique: Follow the manufacturer’s instructions for your on-saw sharpener. Be careful not to overheat the chain.

Data Points: The Impact of Maintenance

Studies have shown that regular chainsaw maintenance can increase the lifespan of the saw by up to 50%. A sharp chain can reduce cutting time by 20% and fuel consumption by 10%. Neglecting maintenance can lead to costly repairs and even dangerous accidents.

Case Study: The Neglected Chainsaw

I once worked with a logger who neglected his chainsaw maintenance. He rarely cleaned the air filter, never sharpened the chain properly, and used the wrong type of oil. His chainsaw constantly broke down, costing him time and money. Eventually, the engine seized due to lack of lubrication. He learned the hard way that neglecting maintenance is a false economy.

Troubleshooting Common Problems

Chainsaw won’t start: Check the fuel level, spark plug, and air filter. If the problem persists, the carburetor may need cleaning or adjustment.
Chainsaw stalls: Check the fuel filter and air filter. The carburetor may also need adjustment.
Chainsaw cuts poorly: Sharpen the chain or replace it if necessary. Check the chain tension and lubrication.
Chainsaw vibrates excessively: Check the chain tension and bar alignment. The anti-vibration mounts may also be worn.

Pro Logging Tip #2: Mastering Felling Techniques

Felling a tree is a serious undertaking. It requires careful planning, precise execution, and a healthy dose of respect for the power of nature.

Planning the Fell

Assess the Tree: Evaluate the tree’s lean, branch distribution, and any signs of decay or weakness. Look for widow makers (broken or hanging branches) that could fall unexpectedly.
Identify Hazards: Look for power lines, buildings, roads, and other obstacles that could be damaged by the falling tree.
Plan Your Escape Route: Clear a path away from the tree at a 45-degree angle to the direction of the fall.
Consider the Weather: Wind can significantly affect the direction of the fall. Avoid felling trees in high winds.

The Felling Cut Sequence

The Undercut: This cut is made on the side of the tree in the direction you want it to fall. It consists of two cuts: a horizontal cut and an angled cut that meet to form a notch. The notch should be about one-third of the tree’s diameter.
The Back Cut: This cut is made on the opposite side of the tree from the undercut. It should be slightly higher than the horizontal cut of the undercut, leaving a hinge of wood between the two cuts. The hinge controls the direction of the fall.
The Felling Wedge: Insert a felling wedge into the back cut to help guide the fall and prevent the saw from binding. Drive the wedge in with a hammer or axe until the tree begins to lean in the desired direction.

Advanced Felling Techniques

Hinge Modifications: The shape and size of the hinge can be adjusted to control the direction and speed of the fall. A thicker hinge will slow the fall, while a thinner hinge will allow it to fall more quickly.
Pulling Techniques: In some cases, it may be necessary to use a rope or winch to pull the tree in the desired direction. This is especially useful for trees that are leaning in the wrong direction.
Boring Cut: This technique involves boring a hole through the center of the tree before making the back cut. This can help to relieve tension and prevent the tree from splitting.

Safety First

Wear appropriate personal protective equipment (PPE), including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
Maintain a safe distance from the tree while it is falling.
Be aware of your surroundings and watch out for falling branches and other hazards.
Never fell a tree alone. Always work with a partner who can assist you in case of an emergency.

Data Points: Felling Accidents

According to the Occupational Safety and Health Administration (OSHA), logging is one of the most dangerous occupations in the United States. Many logging accidents are caused by improper felling techniques. Proper training and adherence to safety protocols can significantly reduce the risk of injury.

Case Study: The Widow Maker

I once witnessed a near-fatal accident involving a widow maker. A logger was felling a tree when a large, broken branch fell from above, striking him on the head. He was wearing a helmet, which likely saved his life. This incident served as a stark reminder of the importance of being aware of your surroundings and taking precautions against falling debris.

Troubleshooting Felling Problems

Tree doesn’t fall in the desired direction: Check the hinge and the undercut. The hinge may be too thick or the undercut may not be deep enough.
Saw binds in the cut: Use a felling wedge to prevent the saw from binding.
Tree splits during the fall: Use a boring cut to relieve tension.

Pro Logging Tip #3: Bucking and Limbing – From Tree to Usable Logs

Once the tree is on the ground, the real work begins. Bucking and limbing are the processes of cutting the tree into manageable logs and removing the branches.

Limbing Techniques

Work from the base of the tree towards the top. This will prevent you from getting trapped under falling branches.
Use a chainsaw or an axe to remove the branches. Be careful not to damage the main trunk of the tree.
Cut branches flush with the trunk. This will make the logs easier to handle and process.
Be aware of spring poles. These are branches that are bent under tension. They can snap back violently when cut.

Bucking Techniques

Measure the logs according to your desired length. Use a measuring tape or a bucking stick.
Use a chainsaw to cut the logs to length. Be careful not to pinch the saw.
Use a log jack or a cant hook to lift the logs for easier cutting.
Be aware of tension and compression wood. This type of wood can split or bind the saw.

Safe Bucking Practices

Always stand on the uphill side of the log. This will prevent the log from rolling on you.
Use chocks to prevent logs from rolling.
Be aware of your surroundings and watch out for other workers.
Never buck a log alone. Always work with a partner who can assist you in case of an emergency.

Data Points: Wood Waste

Inefficient bucking and limbing can lead to significant wood waste. Proper planning and technique can minimize waste and maximize the value of the timber. Studies have shown that optimized bucking strategies can increase timber yield by up to 15%.

Case Study: The Efficient Logger

I once worked with a logger who was incredibly efficient at bucking and limbing. He used a combination of skill, experience, and the right tools to maximize his timber yield. He carefully planned each cut, taking into account the size and shape of the tree. He also used a log jack and a cant hook to make the work easier and safer.

Troubleshooting Bucking and Limbing Problems

Saw binds in the cut: Use a log jack or a cant hook to lift the log.
Log splits during the cut: Use a boring cut to relieve tension.
Branches are difficult to remove: Use a sharp axe or a chainsaw with a limbing bar.

Pro Logging Tip #4: Firewood Preparation – From Log to Cozy Warmth

Firewood preparation is more than just splitting logs. It’s about understanding wood species, seasoning techniques, and efficient stacking methods.

Wood Species and Firewood Quality

Different wood species have different burning characteristics. Some species burn hot and fast, while others burn slow and steady.

Hardwoods: These are generally the best choice for firewood. They are dense, burn hot, and produce long-lasting coals. Examples include oak, maple, ash, and birch.
Softwoods: These are less desirable for firewood. They are less dense, burn faster, and produce more smoke. Examples include pine, fir, and spruce.

Seasoning Firewood

Seasoning is the process of drying firewood to reduce its moisture content. Green wood (freshly cut wood) has a high moisture content, which makes it difficult to burn and produces a lot of smoke. Seasoned wood has a low moisture content, which makes it easy to burn and produces less smoke.

Ideal Moisture Content: The ideal moisture content for firewood is below 20%.
Drying Time: The drying time for firewood depends on the species of wood, the climate, and the stacking method. Generally, it takes at least six months to a year to properly season firewood.
Testing Moisture Content: You can use a moisture meter to test the moisture content of firewood.

Stacking Firewood

Proper stacking is essential for efficient seasoning. The goal is to allow air to circulate freely around the wood.

Stack the wood in a single row, with the bark facing up.
Leave space between the rows to allow for air circulation.
Elevate the wood off the ground to prevent moisture from wicking up from the soil.
Cover the top of the stack to protect it from rain and snow.

Splitting Techniques

Use a splitting maul or a hydraulic log splitter.
Split the logs along the grain.
Wear appropriate PPE, including eye protection, gloves, and steel-toed boots.
Be aware of your surroundings and watch out for other workers.

Data Points: Seasoning Efficiency

Studies have shown that proper seasoning can increase the heat output of firewood by up to 50%. Unseasoned wood can also damage your chimney due to creosote buildup.

Case Study: The Seasoned Firewood Expert

I know a firewood producer who is a master of seasoning. He carefully selects the right wood species, stacks it properly, and monitors the moisture content regularly. His firewood is always dry, clean, and burns hot. He charges a premium price for his firewood, but his customers are happy to pay it because they know they are getting a high-quality product.

Troubleshooting Firewood Problems

Firewood is difficult to split: The wood may be green or knotty.
Firewood produces a lot of smoke: The wood is not properly seasoned.
Firewood burns poorly: The wood may be the wrong species or it may be damp.
