Stihl Knock Off Chainsaw Guide (5 Pro Tips for Woodcutters)

The chainsaw market is booming. It’s no longer just a tool for professional loggers; homeowners, DIY enthusiasts, and even artists are embracing the power and versatility of these machines. However, the price of premium brands like Stihl can be a significant barrier. This has led to a surge in “knock-off” or generic chainsaws, often manufactured overseas and sold at a fraction of the cost. Are they worth it? That’s the question I’m going to address, drawing on my years of experience in wood processing and firewood preparation.

I’ve personally used and maintained various chainsaws, from top-of-the-line Stihls to budget-friendly alternatives. I’ve learned the hard way that price isn’t always the best indicator of performance, but it’s a crucial factor. This guide will equip you with the knowledge to make an informed decision and, if you choose to go the knock-off route, how to get the most out of your investment.

Understanding the Landscape: Genuine vs. Knock-Off

Before diving into the tips, it’s crucial to define what we mean by “knock-off.” These chainsaws are generally designed to resemble popular models from established brands like Stihl, Husqvarna, or Echo. They often share a similar aesthetic, but the internal components, materials, and manufacturing quality can vary drastically.

• Genuine Stihl Chainsaws: These are manufactured by Stihl, a company with a long-standing reputation for quality, durability, and innovation. They invest heavily in research and development, use high-grade materials, and adhere to strict quality control standards.
• Knock-Off Chainsaws: These are typically manufactured by companies that are not affiliated with Stihl. They often use cheaper materials, simpler designs, and less stringent quality control. While some knock-offs may offer reasonable performance for the price, others can be unreliable and even dangerous.

Key Differences to Consider:

• Engine Quality: The engine is the heart of a chainsaw. Genuine Stihl engines are known for their power, efficiency, and longevity. Knock-off engines may be less powerful, less fuel-efficient, and more prone to breakdowns.
• Material Quality: Stihl uses high-quality metals, plastics, and polymers in its chainsaws. Knock-offs often use cheaper materials that are more susceptible to wear and tear, corrosion, and breakage.
• Safety Features: Stihl chainsaws incorporate numerous safety features, such as chain brakes, throttle interlocks, and anti-vibration systems. Knock-offs may have fewer safety features, or those features may be less effective.
• Parts Availability: Stihl has a vast network of dealers and service centers, making it easy to find replacement parts and get your chainsaw serviced. Knock-off parts can be difficult to find, and service may be limited.
• Longevity: A well-maintained Stihl chainsaw can last for many years, even with heavy use. Knock-offs typically have a shorter lifespan.

My Personal Experience: I once purchased a very inexpensive chainsaw online, thinking I was getting a great deal. It looked similar to a Stihl MS 170. However, the engine was weak, the plastic housing cracked easily, and the chain tensioner failed after only a few uses. I ended up spending more time trying to repair it than actually using it. This experience taught me the importance of considering the long-term cost of ownership, not just the initial purchase price.

Now, let’s get into the pro tips.

Pro Tip #1: Inspection is Key Before You Crank

Before even thinking about starting a knock-off chainsaw, a thorough inspection is paramount. You need to be your own quality control department.

• Chain and Bar Alignment: Ensure the chain is properly seated in the bar groove and that the bar is securely attached to the saw body. The chain should move freely without excessive slack. Look for any signs of damage or wear on the chain, bar, or sprocket.
• Tighten Everything: Knock-offs are notorious for having loose bolts and screws. Go over every accessible fastener and tighten it. Pay particular attention to the bar mounting bolts, the muffler bolts, and the carburetor mounting screws. Use the correct size tools to avoid stripping the threads.
• Fuel and Oil Leaks: Check for any fuel or oil leaks around the carburetor, fuel lines, oil tank, and engine seals. Leaks can indicate a serious problem and pose a fire hazard. If you find any leaks, address them before starting the saw.
• Chain Brake Functionality: Test the chain brake to ensure it engages and disengages properly. The chain brake is a critical safety feature that can prevent serious injury in the event of kickback.
• Throttle and Trigger Operation: Make sure the throttle and trigger operate smoothly and return to their idle position when released. A sticky or unresponsive throttle can be dangerous.

Measurement and Specification:

• Chain Tension: The chain should have approximately 1/8 inch of slack. You should be able to pull the chain away from the bar slightly, but it should not sag excessively.
• Bar Mounting Bolt Torque: Refer to the chainsaw’s manual for the recommended torque specification for the bar mounting bolts. If you don’t have a manual, a general guideline is to tighten them to 15-20 Nm.

Why This Matters: Knock-off chainsaws often suffer from poor assembly and quality control. A pre-start inspection can identify and correct potential problems before they lead to damage or injury.

My Experience: I once neglected to inspect a knock-off chainsaw before using it. The bar mounting bolts were loose, and the bar came off during operation. Fortunately, I wasn’t injured, but it could have been much worse. This experience reinforced the importance of thorough pre-start inspections.

Pro Tip #2: Fueling and Lubrication: The Lifeblood of Your Saw

The fuel and lubrication systems are critical to the performance and longevity of any chainsaw, but especially a knock-off. Skimping here will drastically shorten the saw’s lifespan.

• Fuel Mixture: Most two-stroke chainsaw engines require a specific fuel mixture of gasoline and two-stroke oil. The correct ratio is crucial for proper lubrication and cooling. Refer to the chainsaw’s manual for the recommended fuel mixture ratio. Typically, it’s 50:1 (gasoline to oil). Always use high-quality two-stroke oil specifically designed for air-cooled engines.
• Bar and Chain Oil: The bar and chain oil lubricates the chain and bar, reducing friction and wear. Use a high-quality bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication and can damage the chain and bar.
• Fuel Filter and Air Filter: Inspect the fuel filter and air filter regularly and clean or replace them as needed. Clogged filters can restrict airflow and fuel flow, leading to poor performance and engine damage.
• Oil Pump Adjustment: Some chainsaws have an adjustable oil pump that allows you to control the amount of oil delivered to the chain and bar. Adjust the oil pump to ensure adequate lubrication, especially when cutting hardwoods or using a long bar.

Measurements and Specifications:

• Fuel Mixture Ratio: 50:1 (gasoline to two-stroke oil) is the most common ratio. Always consult the chainsaw’s manual for the specific recommendation.
• Bar and Chain Oil Viscosity: Use a bar and chain oil with a viscosity grade of ISO VG 100 or higher for optimal lubrication.
• Fuel Filter Replacement: Replace the fuel filter every 25-50 hours of use, or more frequently if you’re cutting in dusty conditions.
• Air Filter Cleaning: Clean the air filter after each use, or more frequently if you’re cutting in dusty conditions. Replace the air filter every 100-200 hours of use.

Why This Matters: Knock-off chainsaws often have less precise fuel and oil systems than genuine models. Using the correct fuel mixture and bar and chain oil is essential for preventing engine damage and premature wear.

My Experience: I once used the wrong fuel mixture in a knock-off chainsaw. The engine overheated and seized up after only a few hours of use. I learned the hard way that following the manufacturer’s recommendations for fuel and lubrication is crucial.

Pro Tip #3: Mastering the Starting Sequence: Patience is a Virtue

Starting a knock-off chainsaw can be challenging, especially when it’s cold. Patience and the correct starting sequence are essential.

• Choke Setting: Most chainsaws have a choke lever that restricts airflow to the carburetor, enriching the fuel mixture for starting. When starting a cold engine, engage the choke. Once the engine starts and runs briefly, disengage the choke.
• Primer Bulb: Some chainsaws have a primer bulb that pumps fuel into the carburetor. Press the primer bulb several times before attempting to start the engine.
• Starting Cord: Pull the starting cord with a smooth, steady motion. Avoid jerking or yanking the cord, as this can damage the starter mechanism.
• Half-Throttle Position: Once the engine starts and runs briefly, move the throttle to the half-throttle position and continue pulling the starting cord until the engine starts and idles smoothly.
• Warm-Up: Allow the engine to warm up for a few minutes before putting it under load. This will help to ensure proper lubrication and prevent engine damage.

Step-by-Step Starting Sequence:

1. Engage the chain brake. This is a crucial safety step.
2. Place the chainsaw on a firm, level surface.
3. Engage the choke (for a cold engine).
4. Press the primer bulb several times (if equipped).
5. Pull the starting cord with a smooth, steady motion until the engine starts and runs briefly.
6. Disengage the choke.
7. Move the throttle to the half-throttle position.
8. Continue pulling the starting cord until the engine starts and idles smoothly.
9. Allow the engine to warm up for a few minutes before putting it under load.

Why This Matters: Knock-off chainsaws often have less reliable starting mechanisms than genuine models. Following the correct starting sequence can help to improve starting performance and prevent damage to the starter mechanism.

My Experience: I struggled to start a knock-off chainsaw for over an hour because I didn’t know the correct starting sequence. I eventually learned that I needed to use the choke and half-throttle position to get it started. This experience taught me the importance of understanding the specific starting procedure for each chainsaw.

Pro Tip #4: Cutting Techniques and Maintenance: Extend the Life of Your Blade

Proper cutting techniques and regular maintenance are essential for maximizing the performance and lifespan of any chainsaw, especially a knock-off.

• Cutting Techniques: Use proper cutting techniques to avoid kickback, pinching, and other hazards. Always maintain a firm grip on the chainsaw with both hands and keep your body balanced. Cut with the lower portion of the bar, and avoid cutting with the tip of the bar, as this can increase the risk of kickback.
• Chain Sharpening: Keep the chain sharp. A dull chain requires more force to cut, which can strain the engine and increase the risk of kickback. Use a chainsaw file or a chain grinder to sharpen the chain regularly.
• Bar Maintenance: Clean the bar groove regularly to remove sawdust and debris. Check the bar rails for wear and damage, and file them smooth if necessary.
• Sprocket Maintenance: Inspect the sprocket regularly for wear and damage, and replace it as needed. A worn sprocket can damage the chain and reduce cutting performance.
• Chain Tension Adjustment: Adjust the chain tension regularly to ensure proper cutting performance and prevent the chain from derailing.

Cutting Techniques to Avoid Kickback:

• Avoid cutting with the tip of the bar.
• Maintain a firm grip on the chainsaw with both hands.
• Keep your body balanced.
• Be aware of your surroundings and avoid cutting in areas where the chain could strike an object.

Chain Sharpening Specifications:
