Introduction
This manual provides essential information for the safe and efficient operation, maintenance, and troubleshooting of your ECHO CS-590-20AA 20-inch 59.8 cc Gas Chainsaw. Please read this manual thoroughly before operating the chainsaw to ensure proper use and to prevent injury or damage.
Safety Information
Operating a chainsaw can be dangerous if proper safety precautions are not followed. Always wear appropriate personal protective equipment (PPE), including a helmet, eye protection, hearing protection, gloves, and chainsaw protective chaps. Ensure a clear work area and be aware of your surroundings. Never operate the chainsaw under the influence of alcohol or drugs. Refer to the full safety guidelines provided with your product for detailed instructions.
Setup
1. Fueling the Chainsaw
The ECHO CS-590-20AA requires a specific fuel mixture of gasoline and 2-stroke engine oil. Always use fresh, unleaded gasoline with a minimum octane rating of 89 or higher. Mix the gasoline with high-quality 2-stroke engine oil at the ratio specified in your product's detailed manual (typically 50:1 for ECHO products, but always verify). Fill the fuel tank carefully, avoiding spills.

2. Filling Chain Oil
The chainsaw requires bar and chain oil to lubricate the guide bar and saw chain during operation. Use a high-quality bar and chain oil. Fill the chain oil tank, ensuring it is not overfilled. Regularly check the chain oil level during operation.

- Pull the starter handle firmly and quickly until the engine "pops" or attempts to start.
- Move the master control lever to the "RUN" position.

4. Basic Cutting Techniques
- Felling: Plan your felling direction, clear the area, and make proper felling cuts (notch and back cut).
- Limbing: Remove branches from a fallen tree. Work from the base towards the top, cutting smaller branches first.
- Bucking: Cut a fallen log into shorter sections. Be aware of tension and compression in the wood to avoid pinching the bar or kickback.
Maintenance
Regular maintenance ensures the longevity and safe operation of your chainsaw. Always disconnect the spark plug wire before performing any maintenance.
- Chain Sharpening: Keep the saw chain sharp for efficient and safe cutting. Use a round file of the correct diameter for your chain.
- Guide Bar Maintenance: Clean the guide bar groove and oil holes regularly. Flip the bar periodically to ensure even wear.
- Air Filter Cleaning: Clean the air filter frequently, especially in dusty conditions, to maintain engine performance.
- Spark Plug Inspection: Inspect and clean the spark plug periodically. Replace if electrodes are worn or fouled.
- General Cleaning: Keep the chainsaw clean from sawdust, debris, and oil residue.
