I’ve used the CS-3510 to clear fallen limbs and cut through fairly thick logs. Even after extensive use, it’s not just the performance that stands out but also the minimal fatigue thanks to its design. Even as the chain started to loosen—a common issue with new chainsaws—it was nothing a quick adjustment couldn’t fix.

Pros of the ECHO CS-3510 Chainsaw

  • The CS-3510 is exceptionally light, making it easy to handle, especially for extended periods of use. This reduces fatigue and makes it accessible even for users who might find heavier models cumbersome.
  • Despite its size, the chainsaw packs sufficient power to handle tasks typically reserved for heavier models. This includes cutting through medium to thick branches and logs, making it versatile for a range of tasks around the yard.
  • It comes with several features that enhance ease of use, such as the translucent fuel and oil tanks for easy monitoring of fluid levels, and an air injection system that helps keep the air filter and engine clean, extending the life of the chainsaw.
  • The ECHO Easy Start system reduces the effort needed to start the saw by 30%, which is a significant advantage for those who struggle with starting traditional chainsaws due to the high pull force usually required.
  • Features like the inertia-activated chain brake enhance safety during operation. The saw also includes practical maintenance features, such as a grommet system for easy fuel line replacement and metal locking tabs that secure the air filter cover more reliably than the more common plastic alternatives.

Cons of the ECHO CS-3510 Chainsaw

  • The chainsaw only comes with a 16-inch bar. While this is adequate for most tasks typical of home yard care, it may not suffice for those needing to regularly cut larger diameter logs or for more heavy-duty tasks.
  • Like many new chainsaws, the CS-3510 may require frequent chain adjustments early on, as the chain tends to loosen quickly with initial use. This could be a minor inconvenience until the chain is fully broken.
  • The oil pump isn’t adjustable, which means it automatically regulates the bar and chain lubrication based on the engine’s speed. While this is efficient, it might not suit all cutting conditions or personal preferences, especially in varying weather conditions or with different types of wood.
  • Given that it only supports a 16-inch bar, users looking to fit a smaller or larger bar for specific tasks might find this limitation a bit restrictive.
  • While it offers great power-to-weight ratio, it’s still not equivalent to heavier, more powerful models designed for commercial use or for cutting very large trees. Users needing more substantial power might find the CS-3510 inadequate for such demands.

Maintenance of ECHO CS-3510 Chainsaw

Maintaining your ECHO CS-3510 chainsaw is crucial for ensuring it operates efficiently and lasts for many years. Here’s a detailed guide on how to maintain your CS-3510, covering general care, cleaning, and the replacement of vital components.

Regular Maintenance Schedule:

  1. Before Each Use
    • Check the Chain Tension: Ensure the chain is neither too tight nor too loose. A properly tensioned chain should slightly hang from the bar’s underside but not so much that you can pull the drive links out of the bar nose.
    • Inspect the Chain Sharpness: Dull chains make cutting laborious and dangerous. Sharpen the teeth or replace the chain if necessary.
    • Check for Loose Fasteners and Parts: Ensure that nuts, bolts, and screws are tightened.
    • Ensure Proper Bar Oil Level: Fill the chain oil reservoir to ensure proper lubrication during use.
  2. After Each Use

    • Inspect the Air Filter: Clean the air filter with a soft brush or replace it if it is excessively dirty or damaged. This ensures the engine gets adequate air flow, which is crucial for its performance and longevity.
  3. Monthly:
    • Deep Clean the Chainsaw: Disassemble parts such as the chain, bar, and sprocket to thoroughly clean each component. Check the bar for wear and turn it over to promote even wear.
    • Inspect the Spark Plug: Remove the spark plug and check its condition. Replace it if it’s fouled or worn out to ensure easy starting and efficient engine operation.
    • Check the Fuel Filter: Replace the fuel filter every few months to ensure clean fuel is entering the engine, which is essential for smooth operation and to avoid engine problems.
  4. Seasonally
    • Gear and Sprocket Maintenance: Check the drive sprocket for wear and replace it if necessary. Lubricate the clutch drum bearing with a few drops of oil.
    • Check Anti-vibration Springs: Ensure that the anti-vibration mounts are not worn out or damaged to maintain comfort during use and reduce wear on other components.
  5. Storage Maintenance
    • Empty the Fuel Tank in Ventilated Area: Before long-term storage, run the engine until the fuel system is empty, which prevents the carburetor from getting clogged with varnish deposits from stale fuel.
    • Oil the Metal Surfaces: Apply a light coat of oil to all metal surfaces to prevent rust.
    • Store in a Dry, Safe Place: Keep the chainsaw in a dry place and out of the reach of children.

Special Considerations:

  • Air Filter Maintenance: The CS-3510 comes with a new-style air filter. Regular cleaning is required, more often in dusty conditions. To clean the air filter, remove the filter cover using the metal locking tabs, take out the filter, and clean it using non-flammable cleaning solvent or soapy water. Rinse it thoroughly and dry it before reinstallation.
  • Grommet System for Fuel Lines: This model features a convenient grommet system for easy replacement of fuel lines. If you notice fuel leaks or if the saw has trouble starting, check this system. To replace, pop out the old grommet, insert a new one pre-assembled with new fuel lines, and ensure it’s securely in place.

Regular maintenance of your ECHO CS-3510 chainsaw will keep it running smoothly and efficiently, ensuring you’re always ready for yard work. Always refer to the user manual for specific maintenance instructions and safety information.
