4. Setup
4.1 Fuel and Oil Mixture
The ECHO CS-3510ES is a 2-stroke engine and requires a specific fuel mixture. Use high-quality unleaded gasoline mixed with a premium 2-stroke engine oil at a ratio specified by ECHO (typically 50:1 or 25:1, refer to the fuel cap or a dedicated sticker on the unit for exact ratio). Always use fresh fuel mixture.
4.2 Chain Oil
Fill the chain oil tank with high-quality bar and chain oil. This oil lubricates the chain and guide bar during operation. Do not use waste oil or motor oil.
4.3 Guide Bar and Chain Installation
- Ensure the engine is off and the spark plug cap is disconnected.
- Remove the chain cover nuts and the chain cover.
- Place the chain around the clutch drum and guide bar, ensuring the cutting edges face the correct direction.
- Fit the guide bar onto the studs and align the chain with the groove in the guide bar.
- Replace the chain cover and loosely tighten the nuts.
- Adjust chain tension using the tensioning screw. The chain should be snug against the guide bar but still able to be pulled freely by hand.
- Tighten the chain cover nuts securely.
5. Operating Instructions
5.1 Starting the Chainsaw (ES-Start System)
Figure 5.1: Demonstrating the starting procedure for the ECHO CS-3510ES chainsaw.
- Place the chainsaw on a firm, flat surface.
- Engage the chain brake by pushing the front hand guard forward.
- For a cold engine, pull the choke lever out fully. For a warm engine, the choke may not be necessary.
- Press the primer bulb several times until fuel is visible.
- Hold the chainsaw firmly with one hand on the front handle and place your foot on the rear handle.
- Pull the starter rope with a smooth, steady motion until the engine fires (usually a few pulls).
- Once the engine fires, push the choke lever in halfway (if applicable) or fully in.
- Pull the starter rope again until the engine starts and runs.
- Allow the engine to warm up for a few moments, then disengage the chain brake by pulling the front hand guard back.
