Chain for Milwaukee Chainsaw: Top (5 Pro Tips) to Stop Chain Throwing

Chain throwing, that dreaded moment when your chainsaw chain leaps off the guide bar, is a common problem that plagues both seasoned professionals and weekend warriors alike. It’s more than just an inconvenience; it’s a safety hazard that can lead to serious injuries. A thrown chain can whip around with tremendous force, potentially causing cuts, bruises, or even eye injuries. In my experience, preventing chain throwing isn’t just about knowing the right techniques; it’s about understanding the underlying causes and addressing them proactively.

The good news is that most instances of chain throwing are preventable with a little knowledge and attention to detail. By understanding the common causes and implementing the right preventive measures, you can significantly reduce the risk of chain throwing and keep your Milwaukee chainsaw running smoothly and safely.

1. Tension is Key: Mastering Chain Tensioning

Chain tension is arguably the most crucial factor in preventing chain throwing. Too loose, and the chain will naturally want to jump off the bar. Too tight, and you risk excessive wear and tear on the bar, chain, and even the chainsaw’s motor. Finding the sweet spot is essential.

The Goldilocks Zone: Not Too Loose, Not Too Tight

The ideal chain tension is one where you can pull the chain away from the guide bar about 1/8 inch (3mm) at the midpoint of the bar. When you release the chain, it should snap back against the bar. This allows the chain to expand slightly as it heats up during use without becoming dangerously loose.

How to Tension Your Chain Properly

Loosen the Bar Nuts: Use the appropriate wrench to slightly loosen the bar nuts that secure the guide bar to the chainsaw body. These are typically located on the side of the chainsaw.
Adjust the Tensioning Screw: Locate the chain tensioning screw, usually found on the side of the chainsaw near the bar nuts. Use a screwdriver to turn the screw. Turning it clockwise tightens the chain, while turning it counterclockwise loosens it.
Check the Tension: As you adjust the tension, frequently check the chain tension by pulling it away from the bar at the midpoint. Aim for the 1/8 inch (3mm) gap.
Tighten the Bar Nuts: Once you’ve achieved the correct tension, tighten the bar nuts securely. Make sure the bar is properly seated against the chainsaw body before fully tightening.
Test Run: Start the chainsaw and let it run at idle for a few seconds. Recheck the chain tension after the chain has warmed up slightly. Adjust as needed.

Pro Tip: The “Warm Chain” Adjustment

Chains expand as they heat up. A chain that’s perfectly tensioned when cold might become too tight during use. That’s why I always do a “warm chain” adjustment. After a few minutes of cutting, I recheck the tension and loosen it slightly if it feels too tight.

My Experience: The Overtightened Chain Debacle

I once had a near disaster when I overtightened a chain on a particularly cold day. The chain was fine when I started, but after about 15 minutes of cutting, it became incredibly tight. The increased friction caused the bar to overheat, and I started to smell burning rubber. Luckily, I caught it in time and loosened the chain before any serious damage occurred. That taught me the importance of checking tension regularly, especially when working in extreme temperatures.

Data Point: Chain Expansion

According to Oregon Products, a leading manufacturer of chainsaw chains and bars, a chainsaw chain can expand by as much as 0.02 inches per foot of bar length when heated. This expansion can significantly affect chain tension, highlighting the need for regular adjustments.

2. Bar None: Inspecting and Maintaining Your Guide Bar

The guide bar is the backbone of your chainsaw, and its condition directly impacts chain performance. A worn, damaged, or poorly maintained bar can contribute significantly to chain throwing.

Common Guide Bar Problems

Worn Rails: The rails of the guide bar are the grooves that the chain rides in. Over time, these rails can wear down, becoming uneven or rounded. This reduces the chain’s stability and increases the likelihood of throwing.
Burrs and Nicks: Hitting rocks, metal, or other hard objects can create burrs and nicks on the guide bar rails. These imperfections can snag the chain and cause it to jump off.
Bent or Twisted Bar: A bent or twisted bar will misalign the chain, making it difficult to maintain proper tension and increasing the risk of throwing.
Lack of Lubrication: Insufficient lubrication can cause excessive friction between the chain and the bar, leading to overheating, wear, and ultimately, chain throwing.

Guide Bar Maintenance Best Practices

Regular Inspection: Before each use, thoroughly inspect your guide bar for any signs of wear, damage, or debris.
Bar Dressing: Use a bar dressing tool (also known as a rail closer) to remove burrs and nicks from the guide bar rails. This tool reshapes the rails, restoring their smooth, even surface.
Bar Grinding: If the rails are severely worn, consider having them professionally ground. This process removes a thin layer of metal, restoring the rails to their original dimensions.
Bar Flipping: Regularly flip your guide bar over to ensure even wear on both rails. This extends the life of the bar and prevents premature failure.
Lubrication: Always use a high-quality bar and chain oil to lubricate the guide bar and chain. Check the oil level frequently and refill as needed.

Pro Tip: The “Paper Test” for Rail Condition

A simple way to check the condition of your guide bar rails is the “paper test.” Hold a piece of paper against the side of the bar and try to slide it along the rails. If the paper snags or tears, it indicates that the rails are uneven or have burrs that need to be addressed.

My Experience: The Neglected Bar Nightmare

I once inherited a chainsaw from a friend who hadn’t taken very good care of it. The guide bar was in terrible shape – the rails were worn down, there were burrs everywhere, and it was covered in old, dried-up oil. I tried to use it, but the chain kept throwing every few minutes. After spending hours wrestling with it, I finally gave up and bought a new guide bar. The difference was night and day. The new bar made the chainsaw run like a dream, and I haven’t had a chain throwing problem since.

Data Point: Bar Wear and Chain Life

According to a study by Stihl, a leading chainsaw manufacturer, a worn guide bar can reduce the lifespan of a chainsaw chain by as much as 50%. This highlights the importance of maintaining your guide bar to protect your investment in chains.

3. Chain Reaction: Choosing and Maintaining the Right Chain

The type of chain you use and its condition play a significant role in preventing chain throwing. Using the wrong chain for the job or neglecting chain maintenance can increase the risk of throwing.

Chain Types and Their Applications

Full Chisel: These chains have square-cornered cutters that provide fast, efficient cutting in clean wood. However, they are more prone to damage from dirt and debris and require more frequent sharpening.
Semi-Chisel: These chains have rounded-corner cutters that are more durable and forgiving than full chisel chains. They are a good choice for cutting dirty or knotty wood.
Low-Profile: These chains have a smaller cutter height, which reduces kickback and makes them easier to control. They are a good choice for beginners and homeowners.
Ripping Chains: These chains are designed for cutting wood parallel to the grain, such as when milling lumber. They have a different cutter geometry than crosscutting chains.

Chain Maintenance Essentials

Sharpening: A dull chain requires more force to cut, which can increase the risk of chain throwing. Sharpen your chain regularly using a chainsaw file or a chain grinder.
Cleaning: Keep your chain clean by removing sawdust, pitch, and other debris. Use a brush and solvent to clean the chain after each use.
Lubrication: Ensure that your chain is properly lubricated by using a high-quality bar and chain oil. Check the oil level frequently and refill as needed.
Replacement: Chains wear out over time and should be replaced when they become excessively worn or damaged.

Pro Tip: The “Filing Angle” Secret

The angle at which you file your chain cutters is critical for optimal performance. Consult your chainsaw’s owner’s manual or a chain sharpening guide to determine the correct filing angle for your chain type. Using the wrong filing angle can result in a dull, inefficient chain that is more prone to throwing.

My Experience: The Mismatched Chain Mishap

I once tried to use a ripping chain for crosscutting firewood. The chain was incredibly slow and inefficient, and it kept getting stuck in the wood. After struggling for a while, I realized my mistake and switched to a crosscutting chain. The difference was remarkable. The crosscutting chain zipped through the wood with ease, and I was able to finish the job in a fraction of the time.

Data Point: Sharpness and Cutting Efficiency

According to a study by the University of Maine, a sharp chainsaw chain can cut wood up to 50% faster than a dull chain. This increased efficiency reduces strain on the chainsaw and minimizes the risk of chain throwing.

4. Oiling the Wheels: Proper Lubrication is Non-Negotiable

Proper lubrication is essential for the smooth operation of your chainsaw and the longevity of its components. Insufficient lubrication can lead to excessive friction, overheating, and premature wear, all of which can contribute to chain throwing.

Understanding Lubrication Systems

Most chainsaws use an automatic oiler system that pumps oil from a reservoir onto the guide bar and chain. The oil lubricates the chain as it travels around the bar, reducing friction and preventing overheating.

Best Practices for Lubrication

Use the Right Oil: Always 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.
Check the Oil Level: Before each use, check the oil level in the reservoir and refill as needed.
Adjust the Oiler: Some chainsaws have an adjustable oiler that allows you to control the amount of oil being delivered to the bar and chain. Adjust the oiler to ensure adequate lubrication without excessive oil consumption.
Clean the Oiler: Regularly clean the oiler to prevent clogs and ensure proper oil flow. Use compressed air or a small brush to remove debris from the oiler ports.

Pro Tip: The “Cardboard Test” for Oiler Function

A simple way to check if your oiler is working properly is the “cardboard test.” Start the chainsaw and hold it a few inches above a piece of cardboard. Run the chain at full throttle for a few seconds. If the oiler is working correctly, you should see a spray of oil on the cardboard.

My Experience: The Seized Chain Catastrophe

I once neglected to check the oil level on my chainsaw before starting a big firewood project. After about an hour of cutting, the chain started to smoke and bind up. I quickly realized that the oil reservoir was empty. The lack of lubrication had caused the chain to overheat and seize onto the bar. I had to spend hours disassembling the chainsaw and cleaning the bar and chain to get it working again.

Data Point: Lubrication and Chain Temperature

According to a study by Husqvarna, a leading chainsaw manufacturer, proper lubrication can reduce the temperature of a chainsaw chain by as much as 50°F (10°C). This reduction in temperature significantly reduces wear and tear and prevents chain throwing.

5. The Human Factor: Technique and Awareness

Even with a perfectly maintained chainsaw, improper technique and a lack of awareness can lead to chain throwing. Understanding how to use your chainsaw safely and effectively is crucial for preventing accidents and ensuring a smooth cutting experience.

Safe Cutting Techniques

Proper Stance: Maintain a stable stance with your feet shoulder-width apart and your weight evenly distributed.
Firm Grip: Grip the chainsaw firmly with both hands. Keep your thumbs wrapped around the handles.
Avoid Pinching: Be aware of the potential for the bar to become pinched in the wood. Use wedges to keep the cut open and prevent pinching.
Watch for Kickback: Kickback is a sudden, violent upward or backward movement of the chainsaw. Be aware of the kickback zone (the upper quadrant of the bar tip) and avoid using it to cut.
Don’t Overreach: Avoid overreaching or cutting above shoulder height. This can compromise your balance and increase the risk of losing control of the chainsaw.

Awareness and Prevention

Inspect Your Work Area: Before starting to cut, inspect your work area for hazards such as rocks, metal, and hidden objects.
Plan Your Cuts: Plan your cuts carefully to avoid pinching and kickback.
Take Breaks: Take frequent breaks to avoid fatigue. Fatigue can impair your judgment and increase the risk of accidents.
Wear Safety Gear: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.

Pro Tip: The “Thumb Rule” for Kickback

A simple way to remember the kickback zone is the “thumb rule.” Extend your thumb along the top of the guide bar. The area above your thumb is the kickback zone.

My Experience: The Close Call with Kickback

I once had a close call with kickback when I was cutting a small branch. I wasn’t paying attention and accidentally touched the tip of the bar to another branch. The chainsaw kicked back violently, nearly knocking me off my feet. I was lucky that I didn’t lose control of the chainsaw or get injured. That experience taught me the importance of always being aware of the kickback zone and taking precautions to avoid it.

Data Point: Kickback Injuries

According to the Consumer Product Safety Commission (CPSC), kickback is the leading cause of chainsaw-related injuries. This highlights the importance of understanding and avoiding kickback.

Bonus Tip: Chain Break Maintenance

A properly functioning chain break can prevent serious injury in the event of kickback or chain throwing. Make sure your chain break is in good working order and that you know how to use it. Test it regularly to ensure it engages quickly and effectively.
