MS660 Chainsaw Maintenance Tips (5 Pro Hacks for Peak Power)

1. The Holy Trinity: Fuel, Air, and Spark

Let’s face it, a chainsaw is just a glorified engine, and like any engine, it needs the right combination of fuel, air, and spark to run smoothly. This isn’t just about filling the tank and pulling the cord; it’s about understanding the nuances of each element.

Fuel: More Than Just Gas

I can’t stress this enough: use high-quality fuel. Don’t cheap out here. Ethanol-blended fuels, especially those with high ethanol content (E15 or E85), can wreak havoc on your MS660. Ethanol absorbs water, which can lead to fuel separation, corrosion, and a host of engine problems. I’ve seen it happen too many times – a perfectly good chainsaw rendered useless by bad fuel.

Pro Tip: Always use fresh fuel, ideally mixed with a fuel stabilizer. I personally prefer a fuel stabilizer like Stabil or Sea Foam. These stabilizers prevent fuel degradation and keep your fuel system clean. Mix your fuel in small batches, enough for a few weeks at most. Don’t let fuel sit in your chainsaw’s tank for extended periods, especially during the off-season.

Data Point: Studies have shown that using fuel stabilizers can extend the life of your fuel by up to 12 months, preventing gumming and varnish buildup in your carburetor.

Air: Breathe Easy, Cut Hard

A clogged air filter is a silent killer. It restricts airflow, causing the engine to work harder and overheat. This can lead to reduced power, increased fuel consumption, and premature engine wear.

Pro Tip: Clean your air filter regularly. I recommend checking it after every 5-10 hours of use, depending on the cutting conditions. If you’re working in dusty or dirty environments, you might need to clean it more frequently.

There are two main types of air filters: felt and nylon mesh. For felt filters, gently tap them to remove loose debris. If they’re heavily soiled, wash them with warm, soapy water, rinse thoroughly, and let them air dry completely before reinstalling. For nylon mesh filters, you can use compressed air to blow out the dirt. Be careful not to damage the filter material.

Unique Insight: Consider upgrading to a high-performance air filter. These filters offer better airflow and filtration, which can improve your chainsaw’s performance and extend its engine life. Brands like K&N offer aftermarket filters specifically designed for chainsaws.

Spark: Ignite the Power

A healthy spark plug is crucial for reliable starting and smooth operation. A fouled or worn spark plug can cause misfires, rough idling, and reduced power.

Pro Tip: Inspect your spark plug regularly. Look for signs of wear, such as cracked porcelain, burned electrodes, or excessive carbon buildup. Clean the spark plug with a wire brush or a spark plug cleaner. If the electrodes are worn or the spark plug is heavily fouled, replace it.

Data Point: A properly gapped spark plug ensures optimal combustion. Refer to your MS660’s owner’s manual for the correct spark plug gap specification. Using a spark plug gapping tool, adjust the gap to the specified dimension.

2. Chain Sharpening: The Sharpest Tool in the Shed

A dull chain is not only inefficient, but it’s also dangerous. It requires more force to cut, increasing the risk of kickback and operator fatigue. A sharp chain, on the other hand, slices through wood effortlessly, making your job easier, faster, and safer.

The Art of Sharpening

There are several ways to sharpen a chainsaw chain:

Hand Filing: This is the most common and versatile method. It requires a round file, a flat file, and a depth gauge tool. The round file is used to sharpen the cutting teeth, while the flat file is used to adjust the depth gauges.
Electric Sharpeners: These sharpeners offer speed and precision. They use a grinding wheel to sharpen the teeth. However, they can be more aggressive and may remove more material than hand filing.
Professional Sharpening: If you’re not comfortable sharpening your chain yourself, you can take it to a professional. They have the tools and expertise to sharpen your chain quickly and accurately.

Pro Tip: I personally prefer hand filing. It allows me to maintain the chain’s original profile and avoid over-sharpening. It also gives me a better feel for the sharpness of the teeth.

Actionable Takeaway: Invest in a good quality chainsaw sharpening kit. These kits typically include a round file, a flat file, a depth gauge tool, and a filing guide. Learning to sharpen your chain properly is one of the most important skills you can acquire as a chainsaw operator.

Maintaining the Depth Gauges

The depth gauges, also known as rakers, control the amount of wood each tooth can cut. If the depth gauges are too high, the chain will cut slowly. If they’re too low, the chain will grab and kick back.

Pro Tip: Check the depth gauges regularly and file them down as needed. Use a depth gauge tool to ensure that the depth gauges are at the correct height.

Data Point: The correct depth gauge setting varies depending on the type of wood you’re cutting. Softer woods require lower depth gauge settings, while harder woods require higher settings. Refer to your chainsaw’s owner’s manual for specific recommendations.

3. Bar and Chain Maintenance: The Foundation of a Smooth Cut

The bar and chain are the heart of your chainsaw. Proper maintenance of these components is essential for optimal performance and longevity.

Bar Maintenance

The chainsaw bar guides the chain and supports it during cutting. Over time, the bar can wear down, develop burrs, or become pinched.

Pro Tip: Regularly inspect your bar for wear and damage. Remove any burrs with a flat file. If the bar is pinched, use a bar rail closer to open it up.

Unique Insight: Flip your bar regularly. This helps to distribute wear evenly and prolong its life. When you flip the bar, also clean the bar groove with a screwdriver or a bar groove cleaner. This removes dirt and debris that can clog the groove and reduce lubrication.

Data Point: Bar oil is crucial for lubricating the chain and bar. Use a high-quality bar oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication.

Chain Maintenance

The chainsaw chain is the cutting element. Proper chain maintenance is essential for safety and efficiency.

Pro Tip: Keep your chain properly tensioned. A loose chain can derail, causing damage to the chainsaw and posing a safety hazard. A tight chain can overheat and wear prematurely.

Actionable Takeaway: Adjust the chain tension according to the manufacturer’s recommendations. A properly tensioned chain should be snug against the bar but still able to be pulled around by hand.

Real Example: I once had a chain derail while cutting a large oak log. The chain snapped, sending pieces of metal flying. Fortunately, I was wearing proper safety gear and wasn’t injured. This incident taught me the importance of chain tension and regular inspection.

4. Oiling System: Keeping Things Slick

Proper lubrication is the lifeblood of your MS660. Without adequate oil, the chain and bar will overheat, causing premature wear and potential damage.

Understanding the Oiling System

The MS660 has an automatic oiling system that pumps oil from the oil tank to the bar and chain. The oil flow rate is adjustable, allowing you to customize the lubrication based on the cutting conditions.

Pro Tip: Check the oil level regularly. I recommend checking it every time you refuel the gas tank. If the oil level is low, refill it with high-quality bar oil.

Unique Insight: Adjust the oil flow rate according to the type of wood you’re cutting. Harder woods require more oil, while softer woods require less.

Data Point: A clogged oiler can starve the chain and bar of lubrication. Clean the oiler regularly to ensure proper oil flow. You can use compressed air or a wire to clear any blockages.

Troubleshooting Oiling Problems

If your chainsaw isn’t oiling properly, there are several things you can check:

Oil Tank: Make sure the oil tank is full and that the oil pickup is not clogged.
Oiler Filter: Clean or replace the oiler filter.
Oiler Pump: Check the oiler pump for damage or wear.
Bar Oil Hole: Make sure the bar oil hole is clear.

Actionable Takeaway: If you’re still having problems with your oiling system, consult a qualified chainsaw mechanic.

5. Storage and Off-Season Maintenance: Preparing for the Long Haul

Proper storage and off-season maintenance are crucial for keeping your MS660 in top condition.

Preparing for Storage

Before storing your chainsaw for an extended period, there are several steps you should take:

Drain the Fuel Tank: Drain the fuel tank completely to prevent fuel degradation and corrosion.
Clean the Chainsaw: Clean the chainsaw thoroughly to remove dirt, sawdust, and oil.
Sharpen the Chain: Sharpen the chain to ensure it’s ready for the next use.
Lubricate the Bar and Chain: Lubricate the bar and chain with bar oil to prevent rust.
Store the Chainsaw in a Dry Place: Store the chainsaw in a dry, well-ventilated place to prevent moisture damage.

Pro Tip: I personally like to run the chainsaw until it stalls after draining the fuel tank. This ensures that all the fuel is out of the carburetor and fuel lines. I also spray a fogging oil into the cylinder to protect the engine from rust and corrosion during storage.

Unique Insight: Store your chainsaw in a case or bag to protect it from dust and damage. This will also help to keep your storage area clean and organized.

Off-Season Maintenance

Even if you’re not using your chainsaw, it’s important to perform regular maintenance to keep it in top condition.

Pro Tip: Start your chainsaw every few months and let it run for a few minutes. This will help to keep the engine lubricated and prevent the carburetor from gumming up.

Actionable Takeaway: Inspect your chainsaw regularly for signs of wear and damage. Replace any worn or damaged parts before they cause further problems.

Case Study: A local logging company I know experienced significant downtime due to neglected off-season maintenance. Their chainsaws were stored improperly, and the carburetors became clogged with old fuel. This resulted in costly repairs and lost production time. This incident highlights the importance of proper storage and off-season maintenance.

Wood Species and Processing Techniques: Tailoring Your Approach

The type of wood you’re cutting can significantly impact your chainsaw’s performance and maintenance requirements. Different wood species have different densities, hardness, and moisture contents, which can affect the chain’s sharpness, the bar’s wear, and the engine’s load.

Understanding Wood Properties

Hardwoods: These woods are denser and harder than softwoods. They require sharper chains and more power to cut. Examples include oak, maple, and hickory.
Softwoods: These woods are less dense and easier to cut. They tend to produce more sawdust and require more frequent chain sharpening. Examples include pine, fir, and spruce.
Moisture Content: Wet wood is heavier and more difficult to cut than dry wood. It also tends to dull the chain more quickly.

Pro Tip: Adjust your cutting technique based on the type of wood you’re cutting. For hardwoods, use a slow, steady pressure and keep the chain sharp. For softwoods, use a faster cutting speed and clean the sawdust frequently. For wet wood, sharpen the chain more often and use plenty of bar oil.

Processing Techniques

Bucking: Cutting logs into shorter lengths.
Felling: Cutting down trees.
Limbing: Removing branches from trees.
Splitting: Dividing logs into smaller pieces for firewood.

Unique Insight: Different processing techniques require different chainsaw techniques. For bucking, use a level cutting surface and avoid pinching the bar. For felling, use proper notch and back cut techniques to control the direction of the fall. For limbing, use caution to avoid kickback. For splitting, use a splitting maul or a hydraulic splitter.

Data Point: Proper felling techniques can reduce the risk of accidents and injuries. According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of logging accidents.
