Let’s dive in, not just as operators, but as educators and role models.

The Husqvarna 136 Chainsaw: A Legacy of Reliability

The Husqvarna 136 is a chainsaw that has earned its stripes. While it might not be the newest model on the market, its reputation for reliability and ease of use makes it a favorite among homeowners and occasional users. I remember my own introduction to chainsaws involved a similar model, perhaps a bit older, but the principles remain the same. The simplicity of the design often translates to easier maintenance, a crucial factor for those of us who prefer to keep our equipment running smoothly without needing a mechanic for every minor hiccup.

Understanding the Core Specs

Before we get into the pro tips, let’s establish a solid understanding of the Husqvarna 136’s specifications. This will serve as our foundation for optimizing performance and extending its lifespan.

• Engine Displacement: Approximately 36 cubic centimeters (cc). This is a key indicator of the engine’s power. A 36cc engine is well-suited for felling small trees, limbing, and cutting firewood.
• Power Output: Around 1.4 kilowatts (kW) or 1.9 horsepower (hp). This tells us how much work the engine can actually perform.
• Recommended Bar Length: Typically 14-16 inches. Using a longer bar than recommended can overstress the engine and reduce cutting efficiency.
• Chain Pitch: Usually .325 inches. This refers to the spacing between the chain’s drive links.
• Chain Gauge: Typically .050 inches (1.3 mm). This is the thickness of the drive links that fit into the guide bar groove.
• Fuel Tank Capacity: Approximately 0.4 liters. Knowing this helps you plan your work sessions and minimize interruptions for refueling.
• Oil Tank Capacity: Around 0.2 liters. Proper chain lubrication is essential for smooth cutting and preventing premature wear.
• Weight (without bar and chain): Approximately 4.6 kilograms (10.1 pounds). Weight is a critical factor for user fatigue, especially during prolonged use.
• Sound Power Level: Typically around 113 dB(A). Always wear hearing protection!
• Vibration Level: Front handle around 6 m/s², rear handle around 8 m/s². High vibration levels can lead to hand-arm vibration syndrome (HAVS), so take frequent breaks.

Data Point: A study by the US Forest Service found that chainsaws with vibration levels exceeding 5 m/s² significantly increased the risk of HAVS among forestry workers.

Fuel and Oil: The Lifeblood of Your Chainsaw

The Husqvarna 136, like most two-stroke engines, requires a precise mixture of gasoline and two-stroke oil. Using the correct fuel and oil mixture is paramount for engine health and longevity.

• Fuel: Use unleaded gasoline with a minimum octane rating of 87 (AKI) or 91 RON. Higher octane fuels won’t necessarily improve performance in this engine, but they won’t hurt either.
• Oil: Use a high-quality two-stroke oil specifically designed for air-cooled engines. Husqvarna’s own two-stroke oil is a reliable choice, but other reputable brands are also acceptable.
• Mixing Ratio: The standard mixing ratio is 50:1 (50 parts gasoline to 1 part oil). Always consult your owner’s manual for the exact ratio recommended for your specific model. I’ve seen engines ruined by incorrect fuel mixtures.
• Mixing Procedure: I always recommend mixing fuel in a separate, clean container. Pour a portion of the gasoline into the container, add the correct amount of two-stroke oil, and then add the remaining gasoline. Shake the mixture thoroughly to ensure proper blending.
• Fuel Storage: Store fuel in a tightly sealed container, away from direct sunlight and heat. Fuel can degrade over time, so it’s best to use fresh fuel within 30 days. Add a fuel stabilizer if storing for longer periods.

Technical Insight: Two-stroke oil provides lubrication for the engine’s internal components, including the piston, cylinder, and crankshaft. Without proper lubrication, these parts will wear rapidly, leading to engine failure.

Chainsaw Chain Selection: Matching the Chain to the Task

Choosing the right chain for your Husqvarna 136 is crucial for efficient cutting and safety. The chain’s pitch and gauge must match the specifications of your chainsaw and guide bar.

• Chain Pitch: As mentioned earlier, the Husqvarna 136 typically uses a .325-inch pitch chain. This is a good all-around pitch for general purpose cutting.
• Chain Gauge: The standard gauge is .050 inches (1.3 mm). Ensure that the chain you select has the correct gauge to fit properly in the guide bar groove.
• Chain Type: There are various types of chainsaw chains available, each designed for specific applications.
  • Full Chisel: These chains have aggressive, square-cornered cutters that provide fast cutting in clean wood. However, they are more prone to dulling in dirty or abrasive conditions.
  • Semi-Chisel: These chains have rounded cutters that are more forgiving and durable than full chisel chains. They are a good choice for general purpose cutting and for working in conditions where the wood may be dirty or contain bark.
  • Low-Kickback: These chains are designed with features that reduce the risk of kickback, a dangerous phenomenon where the chainsaw suddenly jumps back towards the operator. They are a good choice for beginners and for those who prioritize safety.
• Chain Maintenance: Regular chain maintenance is essential for optimal performance and safety. This includes sharpening the chain regularly, checking the chain tension, and lubricating the chain properly.

Practical Tip: I always keep a spare chain on hand, sharpened and ready to go. This allows me to quickly swap out a dull chain and keep working without interruption.

5 Pro Tips for Husqvarna 136 Chainsaw Longevity

Now that we have a good understanding of the Husqvarna 136’s specifications and fuel requirements, let’s move on to the pro tips for extending its lifespan. These tips are based on my years of experience working with chainsaws and observing the common pitfalls that lead to premature wear and tear.

1. Master the Art of Chain Sharpening

A sharp chain is not only more efficient, but it’s also safer. A dull chain requires more force to cut, increasing the risk of kickback and operator fatigue. I cannot stress this enough: learning to sharpen your chain properly is the single most important thing you can do to extend the life of your chainsaw.

• Tools: You’ll need a chainsaw file, a file guide, and a depth gauge tool.
• File Size: The correct file size depends on the chain pitch. For a .325-inch pitch chain, a 5/32-inch (4.0 mm) file is typically used.
• Sharpening Angle: The correct sharpening angle is usually marked on the file guide. Maintain a consistent angle for each cutter.
• Depth Gauge: The depth gauge controls how much the cutter bites into the wood. Use the depth gauge tool to ensure that the depth gauges are set to the correct height.
• Procedure: Secure the chainsaw in a vise. File each cutter with smooth, even strokes, maintaining the correct angle and depth. File all cutters on one side of the chain, then rotate the chainsaw and file the cutters on the other side. Finally, use the depth gauge tool to adjust the depth gauges as needed.

Personal Story: I once worked with a logger who prided himself on never sharpening his chain. He claimed it was “faster” to just push harder. Needless to say, his chainsaw didn’t last long, and his production was significantly lower than mine, despite his brute force approach.

Technical Insight: A properly sharpened chain will produce long, thin shavings of wood. A dull chain will produce sawdust.

2. Chain Lubrication: Don’t Skimp on the Oil!

Proper chain lubrication is absolutely critical for preventing premature wear of the chain, guide bar, and sprocket. The chain travels at high speeds, generating significant friction. Without adequate lubrication, the metal surfaces will overheat and wear rapidly.

• Oil Type: Use a high-quality bar and chain oil specifically designed for chainsaws. These oils are formulated to cling to the chain and provide excellent lubrication under high-speed conditions.
• Oil Level: Check the oil level frequently and refill as needed. I always top off the oil tank before starting a new cutting session.
• Oil Flow: Ensure that the oiler is functioning properly. The oiler should automatically dispense oil onto the chain as it rotates. You can check the oil flow by holding the chainsaw over a piece of cardboard and revving the engine. You should see a spray of oil coming from the chain.
• Cleaning: Regularly clean the guide bar groove and oiler holes to prevent clogs.
• Winter Lubrication: In cold weather, use a lighter viscosity bar and chain oil to ensure proper flow.

Data Point: A study by Oregon State University found that chainsaws with inadequate chain lubrication experienced up to 50% more wear on the chain and guide bar compared to chainsaws with proper lubrication.

3. Air Filter Maintenance: Breathe Easy, Cut Efficiently

A clean air filter is essential for maintaining proper engine performance. A dirty air filter restricts airflow, causing the engine to run rich (too much fuel) and overheat. This can lead to reduced power, increased fuel consumption, and premature engine wear.

• Cleaning Frequency: Clean the air filter regularly, especially when working in dusty conditions. I recommend cleaning it after every 5-10 hours of use.
• Cleaning Method: Remove the air filter and gently tap it to remove loose debris. You can also use compressed air to blow out the filter. If the filter is heavily soiled, wash it with warm soapy water. Allow the filter to dry completely before reinstalling it.
• Replacement: Replace the air filter if it is damaged or excessively dirty. A new air filter is relatively inexpensive and can significantly improve engine performance.

Practical Tip: I keep a spare air filter on hand so I can quickly swap out a dirty filter and keep working.

4. Spark Plug Care: Igniting Performance

The spark plug is responsible for igniting the fuel-air mixture in the engine. A fouled or worn spark plug can cause hard starting, poor performance, and increased fuel consumption.

• Inspection: Inspect the spark plug regularly for signs of fouling or wear. The electrode should be clean and dry. If the electrode is black and oily, it indicates that the engine is running rich. If the electrode is white and ashy, it indicates that the engine is running lean (too little fuel).
• Cleaning: Clean the spark plug with a wire brush to remove any deposits.
• Gap: Check the spark plug gap with a feeler gauge. The correct gap is typically specified in the owner’s manual. Adjust the gap as needed.
• Replacement: Replace the spark plug if it is damaged or worn. A new spark plug is a relatively inexpensive way to improve engine performance.

Technical Insight: The spark plug gap is the distance between the center electrode and the side electrode. A properly gapped spark plug will produce a strong spark that ignites the fuel-air mixture efficiently.

5. Proper Storage: Protecting Your Investment

Proper storage is essential for preventing corrosion and damage to your chainsaw when it’s not in use.

• Cleaning: Clean the chainsaw thoroughly before storing it. Remove any sawdust, dirt, or oil.
• Fuel: Empty the fuel tank or add a fuel stabilizer to prevent fuel degradation.
• Chain and Bar: Remove the chain and guide bar and clean them thoroughly. Lightly oil the chain to prevent rust.
• Storage Location: Store the chainsaw in a dry, protected location away from direct sunlight and extreme temperatures.
• Winter Storage: If storing the chainsaw for an extended period during the winter, consider removing the spark plug and pouring a small amount of oil into the cylinder to prevent corrosion.

Case Study: I once stored a chainsaw in a damp shed for several months without properly preparing it. When I went to use it again, the chain was rusted, the fuel tank was corroded, and the engine was difficult to start. I ended up spending a significant amount of time and money repairing the damage.

Additional Tips for Wood Processing and Firewood Preparation

Beyond the chainsaw itself, there are several other aspects of wood processing and firewood preparation that can impact your efficiency and safety.

Wood Selection Criteria

Choosing the right type of wood for firewood is essential for maximizing heat output and minimizing smoke.

• Hardwoods vs. Softwoods: Hardwoods, such as oak, maple, and birch, are denser and burn longer than softwoods, such as pine and fir. Hardwoods also produce less smoke.
• Moisture Content: The ideal moisture content for firewood is 20% or less. Wood with a high moisture content will be difficult to light, produce excessive smoke, and burn inefficiently.
• Seasoning: Seasoning is the process of drying wood to reduce its moisture content. Wood should be seasoned for at least six months, and preferably a year or more, before burning.

Data Point: A study by the Biomass Energy Resource Center found that firewood with a moisture content of 50% produced only half as much heat as firewood with a moisture content of 20%.

Tool Calibration Standards

Proper tool calibration is essential for accurate and efficient wood processing.

• Chainsaw Calibration: Ensure that the chainsaw is properly calibrated for optimal performance. This includes adjusting the carburetor and chain tension.
• Measuring Tools: Use accurate measuring tools to ensure that logs are cut to the correct length and diameter.
• Splitting Maul: A well-maintained splitting maul is essential for splitting firewood. Keep the blade sharp and the handle secure.

Safety Equipment Requirements

Safety should always be your top priority when working with chainsaws and processing wood.

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet, eye protection, hearing protection, gloves, chainsaw chaps, and sturdy boots.
• First Aid Kit: Keep a well-stocked first aid kit on hand in case of injury.
• Communication: If working in a remote area, ensure that you have a way to communicate with others in case of emergency.

Legal Requirement: OSHA (Occupational Safety and Health Administration) has specific regulations regarding the use of chainsaws in the workplace. Ensure that you are familiar with these regulations and comply with them.

Log Dimensions and Cord Volumes

Understanding log dimensions and cord volumes is essential for accurately estimating the amount of firewood you have.

• Log Diameter: Measure the diameter of the log at the small end.
• Log Length: Measure the length of the log.
• Cord: A cord is a standard unit of measurement for firewood. A cord is a stack of wood that measures 4 feet high, 4 feet wide, and 8 feet long.
• Calculating Cord Volume: You can estimate the cord volume of a stack of wood by multiplying the height, width, and length of the stack and dividing by 128 (the number of cubic feet in a cord).

Practical Example: A stack of wood that measures 4 feet high, 4 feet wide, and 4 feet long has a volume of 64 cubic feet. This is equal to 0.5 cords (64 / 128 = 0.5).

Drying Tolerances and Wood Moisture Content

Understanding drying tolerances and wood moisture content is essential for producing high-quality firewood.

• Moisture Content: As mentioned earlier, the ideal moisture content for firewood is 20% or less.
• Drying Time: The drying time for firewood depends on the type of wood, the climate, and the stacking method. Generally, hardwoods require at least six months of seasoning, while softwoods may dry more quickly.
• Moisture Meter: Use a moisture meter to accurately measure the moisture content of the wood.

Technical Insight: Wood dries from the outside in. The outer layers of the wood will dry more quickly than the inner layers.
