Echo Timberwolf CS-590 Chainsaw: A Complete Guide with Expert Tips

The Echo Timberwolf CS-590 is a popular choice for homeowners and professionals alike. Its blend of power, reliability, and reasonable price point makes it a versatile tool for a variety of tasks, from felling small trees to bucking firewood. But even the best chainsaw needs proper care and technique to perform at its peak. I’ve spent years working with chainsaws, and I’ve developed some insights that can help you maximize your CS-590’s potential.

Understanding the Echo Timberwolf CS-590

Before diving into the tips, let’s get familiar with the CS-590’s key features. This chainsaw boasts a 59.8cc professional-grade, 2-stroke engine. This engine provides ample power for tackling hardwoods and larger diameter logs. It typically comes with a 20-inch bar, which is a good balance between maneuverability and cutting capacity. The CS-590 also features a tool-less air filter cover for easy maintenance, an automatic oiler to keep the chain lubricated, and a vibration reduction system for improved comfort during extended use.

Tip #1: Mastering the Starting Procedure

One of the most common frustrations with chainsaws is difficulty starting them. The CS-590, like most 2-stroke engines, can be finicky if the starting procedure isn’t followed correctly.

The Correct Procedure:

1. Fuel Mix: Always use the correct fuel mixture. Echo recommends a 50:1 ratio of gasoline to 2-stroke oil. Use a high-quality 2-stroke oil specifically designed for air-cooled engines. I personally prefer using a pre-mixed fuel, like TruFuel, to eliminate any mixing errors.
2. Choke: Engage the choke. The choke restricts airflow to enrich the fuel mixture for cold starts.
3. Primer Bulb: Press the primer bulb several times (usually 5-7) until you see fuel entering the bulb. This primes the carburetor.
4. Starting Position: Place the chainsaw on the ground, ensuring the chain is clear of any obstructions. Secure it with your foot through the rear handle.
5. Pull the Starter Rope: Pull the starter rope firmly and steadily. Don’t yank it. Continue pulling until the engine sputters or attempts to start.
6. Disengage the Choke: Once the engine sputters, immediately disengage the choke.
7. Pull Again: Pull the starter rope again until the engine starts and runs smoothly.
8. Warm-Up: Allow the engine to warm up for a minute or two before applying full throttle.

Troubleshooting Starting Issues:

• Flooding: If you pull the rope too many times with the choke engaged, you can flood the engine. To clear a flooded engine, disengage the choke completely and pull the starter rope repeatedly until the engine starts.
• Old Fuel: Old or stale fuel is a common culprit. Gasoline degrades over time, especially when mixed with 2-stroke oil. Always use fresh fuel. If your chainsaw has been sitting for a while, drain the old fuel and replace it with fresh fuel.
• Spark Plug: A fouled or worn spark plug can also prevent the engine from starting. Inspect the spark plug and clean or replace it if necessary. The correct spark plug gap for the CS-590 is typically 0.025 inches.
• Fuel Filter: A clogged fuel filter can restrict fuel flow. Replace the fuel filter if it appears dirty or clogged.

Personal Experience: I recall a time when my CS-590 refused to start after sitting unused for a few months. I initially suspected a spark plug issue, but after cleaning it, the problem persisted. It turned out the fuel filter was completely clogged with residue from old fuel. Replacing the filter solved the problem instantly. This experience taught me the importance of using fresh fuel and regularly inspecting the fuel filter.

Takeaway: Mastering the starting procedure is crucial for reliable operation. Always use fresh fuel, follow the correct steps, and troubleshoot common issues systematically.

Tip #2: Chain Sharpening: The Key to Efficient Cutting

A sharp chain is paramount for safe and efficient chainsaw operation. A dull chain not only requires more effort to cut, but it also increases the risk of kickback, a dangerous situation where the chainsaw suddenly jumps back towards the operator.

Recognizing a Dull Chain:

• The chainsaw requires excessive force to cut.
• The chain produces fine sawdust instead of chips.
• The chainsaw vibrates excessively.
• The cut is uneven or angled.
• Smoke emanates from the cut, indicating excessive friction.

Sharpening Methods:

There are two primary methods for sharpening a chainsaw chain:

1. Hand Filing: This method involves using a round file and a flat file to sharpen each cutting tooth individually. It requires practice and patience, but it allows for precise control over the sharpening process.
2. Chainsaw Sharpener: These tools use a grinding wheel to sharpen the chain. They are faster and easier to use than hand filing, but they can also remove more material from the chain if not used carefully.

Hand Filing Technique:

1. Secure the Chainsaw: Clamp the chainsaw in a vise to prevent it from moving during sharpening.
2. Identify the Correct File Size: Use a round file that matches the pitch of your chain. The CS-590 typically uses a 5/32-inch round file.
3. Use a Filing Guide: A filing guide helps you maintain the correct angle and depth while sharpening.
4. File Each Cutter: File each cutter with smooth, even strokes, following the existing angle of the cutter. Typically, you’ll want to maintain a 30-degree angle for the top plate and a 10-degree angle for the depth gauge (raker).
5. Maintain Uniformity: Ensure that all cutters are sharpened to the same length and angle.
6. Lower the Depth Gauges: After sharpening the cutters, use a flat file and a depth gauge tool to lower the depth gauges (rakers). Lowering the depth gauges allows the cutters to bite into the wood more aggressively.

Chainsaw Sharpener Technique:

1. Follow the Manufacturer’s Instructions: Each chainsaw sharpener has its own specific instructions. Read and understand the instructions before using the sharpener.
2. Set the Correct Angle: Set the sharpener to the correct angle for your chain.
3. Grind Each Cutter: Grind each cutter briefly, using light pressure. Avoid overheating the cutters, as this can damage the steel.
4. Maintain Uniformity: Ensure that all cutters are sharpened to the same length and angle.

Personal Experience: I initially struggled with hand filing, often ending up with unevenly sharpened chains. I invested in a good quality filing guide, and after some practice, I was able to consistently sharpen my chains to a razor-sharp edge. I found that taking my time and focusing on maintaining the correct angles was key to success.

Takeaway: A sharp chain is essential for safe and efficient chainsaw operation. Learn to recognize the signs of a dull chain and sharpen it regularly using either hand filing or a chainsaw sharpener.

Tip #3: Proper Chain Lubrication: Extending Chain and Bar Life

Proper chain lubrication is critical for extending the life of your chainsaw chain and bar. The chain spins at high speeds, generating significant friction. Without adequate lubrication, the chain and bar will overheat, leading to premature wear and potential failure.

Choosing the Right Chain Oil:

• Viscosity: Use a chain oil with the correct viscosity. A thicker oil is generally better for warmer temperatures and heavier use, while a thinner oil is suitable for colder temperatures.
• Tackiness: Choose a chain oil with good tackiness. Tackiness refers to the oil’s ability to cling to the chain and bar, preventing it from being flung off during operation.
• Biodegradability: Consider using a biodegradable chain oil, especially if you are working in environmentally sensitive areas.

Checking the Oil Level:

• Regularly Check: Check the oil level in the oil reservoir before each use and refill as needed.
• Monitor Oil Consumption: Monitor the rate of oil consumption. If the oil reservoir empties too quickly, it may indicate a leak or a problem with the oiler.

Adjusting the Oiler:

• Adjustable Oilers: Some chainsaws, including some CS-590 models, have adjustable oilers. Adjust the oiler to provide adequate lubrication based on the type of wood you are cutting and the operating conditions.
• Observe Oil Flow: Observe the oil flow while the chainsaw is running. You should see a steady stream of oil being dispensed from the bar.

Cleaning the Oiler:

• Clean Regularly: Clean the oiler regularly to prevent clogs. Debris can accumulate in the oiler, restricting oil flow.
• Use Compressed Air: Use compressed air to blow out the oiler and oil passages.

Personal Experience: I once neglected to check the oil level in my CS-590 before starting a large firewood project. After a few hours of cutting, I noticed the chain was smoking and the bar was getting excessively hot. I immediately stopped and discovered the oil reservoir was completely empty. Fortunately, I caught the problem before any serious damage occurred, but it served as a valuable lesson about the importance of proper chain lubrication.

Takeaway: Proper chain lubrication is essential for extending the life of your chainsaw chain and bar. Use the right chain oil, check the oil level regularly, adjust the oiler as needed, and clean the oiler periodically.

Tip #4: Maintaining the Air Filter: Ensuring Optimal Engine Performance

A clean air filter is crucial for maintaining optimal engine performance. The air filter prevents dust and debris from entering the engine, which can cause damage and reduce power.

Checking the Air Filter:

• Regular Inspections: Check the air filter regularly, especially when working in dusty conditions.
• Frequency: I recommend checking the air filter after every 5-10 hours of use, or more frequently if needed.

Cleaning the Air Filter:

• Remove the Filter: Remove the air filter from the chainsaw.
• Tap it Clean: Tap the filter gently to remove loose debris.
• Wash with Soap and Water: Wash the filter with warm soapy water. Rinse thoroughly and allow it to air dry completely before reinstalling it.
• Compressed Air: You can also use compressed air to blow out the filter, but be careful not to damage the filter element.

Replacing the Air Filter:

• Replace When Damaged: Replace the air filter if it is damaged or excessively dirty.
• Recommended Schedule: I recommend replacing the air filter at least once a year, or more frequently if you use the chainsaw heavily.

Personal Experience: I once experienced a significant power loss with my CS-590 while cutting some hardwood logs. I initially suspected a fuel issue, but after checking the fuel lines and carburetor, I discovered the air filter was completely clogged with sawdust. Cleaning the air filter restored the engine’s power instantly. This experience highlighted the importance of regularly maintaining the air filter.

Takeaway: A clean air filter is essential for maintaining optimal engine performance. Check the air filter regularly, clean it as needed, and replace it when necessary.

Tip #5: Safe Chainsaw Operation: Prioritizing Safety

Chainsaw operation is inherently dangerous, and it’s crucial to prioritize safety at all times. Accidents can happen quickly and have serious consequences.

Essential Safety Gear:

• Helmet: Wear a helmet with a face shield or safety glasses to protect your head and eyes from flying debris.
• Hearing Protection: Wear hearing protection to protect your ears from the loud noise of the chainsaw.
• Gloves: Wear gloves to protect your hands from cuts and abrasions.
• Chaps: Wear chainsaw chaps to protect your legs from accidental cuts. Chainsaw chaps are made of special material that will jam the chain and stop it from cutting into your leg.
• Boots: Wear sturdy, steel-toed boots to protect your feet.

Safe Cutting Techniques:

• Proper Stance: Maintain a stable stance with your feet shoulder-width apart.
• Firm Grip: Grip the chainsaw firmly with both hands.
• Avoid Overreaching: Avoid overreaching or cutting above shoulder height.
• Be Aware of Kickback: Be aware of the risk of kickback and take steps to avoid it. Kickback occurs when the tip of the bar contacts a solid object, causing the chainsaw to suddenly jump back towards the operator. Avoid using the tip of the bar to cut.
• Clear the Area: Clear the area around you of any obstacles or tripping hazards.
• Work Alone: Never work alone. Always have someone nearby in case of an accident.

Maintenance and Inspection:

• Inspect Before Each Use: Inspect the chainsaw before each use to ensure that it is in good working condition. Check the chain, bar, oil level, and air filter.
• Sharpen the Chain Regularly: Sharpen the chain regularly to reduce the risk of kickback and improve cutting efficiency.
• Maintain the Chainsaw: Maintain the chainsaw according to the manufacturer’s instructions.

Personal Experience: I witnessed a logging accident early in my career that profoundly impacted my approach to chainsaw safety. A fellow logger, rushing to meet a deadline, neglected to wear his chaps. A momentary lapse in concentration resulted in a severe leg injury. The incident served as a stark reminder that even experienced professionals can make mistakes, and that complacency can have devastating consequences.

Takeaway: Chainsaw operation is inherently dangerous, and it’s crucial to prioritize safety at all times. Wear essential safety gear, use safe cutting techniques, and maintain the chainsaw properly.
