Configuración
1. Desembalaxe
Retire con coidado todos os compoñentes da embalaxe. Comprobe que todas as pezas enumeradas na lista de embalaxe estean presentes e non estean danadas. Garde a embalaxe para o seu almacenamento ou transporte futuros.
2. Mestura de combustible e aceite
The Echo CS-310 uses a 2-stroke engine and requires a specific fuel mixture. Use fresh, unleaded gasoline with an octane rating of 89 or higher, mixed with high-quality 2-stroke engine oil at a Relación 50:1 (2.6 fl. oz. of oil per gallon of gasoline). Do not use E-gas (ethanol contaminated gas) as it can cause issues with small engines.
- Mesturar o combustible nun recipiente de combustible limpo e homologado.
- Axite ben a mestura antes de encher o depósito de combustible.
- Fill the chain oil tank with good quality bar and chain oil. The automatic oiler requires a constant supply of oil. Check the oil level frequently, ideally with every fuel refill.
3. Instalación de barras e cadeas
Refer to the detailed instructions in your manual for proper installation of the guide bar and saw chain. Ensure the chain is correctly tensioned; it should be snug but still able to be pulled around the bar by hand.
Instrucións de funcionamento
1. Arranque do motor
Inicio frío:
- Place the chain saw on a firm, flat surface.
- Enganche o freo da cadea.
- Move a palanca do estrangulador á posición FULL CHOKE.
- Press the purge pump bulb 5-7 times until fuel is visible in the return line.
- Pull the starter handle firmly and steadily until the engine "pops" or attempts to start (usually 3-5 pulls).
- Move a palanca do estrangulador á posición HALF CHOKE.
- Pull the starter handle again until the engine starts.
- Once the engine runs, disengage the choke by briefly pressing the throttle trigger.
- Deixe que o motor quente uns intres antes de desacoplar o freo da cadea e comezar a traballar.
Inicio quente:
- Enganche o freo da cadea.
- Move a palanca do estrangulador á posición OFF.
- Tire da manilla de arranque ata que o motor arranque.
2. Técnicas de corte
Always maintain a firm grip on both handles. Stand with good balance and footing. Plan your cuts to avoid kickback and ensure the tree or limb falls in the desired direction. Start cutting with the chain brake engaged, then disengage it just before making the cut.
- Tala: For cutting down trees. Requires careful planning of escape routes and hinge creation.
- Limbing: Removing branches from a fallen tree. Work from the base towards the top, supporting the log to prevent pinching.
- Retorno: Cutting a fallen log into smaller sections. Be aware of tension and compression in the wood.
3. Parar o motor
To stop the engine, release the throttle trigger and move the ignition switch to the "STOP" position. Engage the chain brake immediately after stopping the engine.
Mantemento
Regular maintenance is crucial for the longevity and safe operation of your chain saw.
1. Afiado da cadea
A sharp chain is essential for efficient and safe cutting. Sharpen the chain regularly using a round file of the correct diameter (refer to your chain's specifications) or have it professionally sharpened. A dull chain will produce fine sawdust instead of chips and require more force to cut.
2. Bar Maintenance
Clean the guide bar groove and oil holes regularly. Flip the bar periodically to ensure even wear. Check for burrs on the bar rails and file them smooth if present.
3. Limpeza do filtro de aire
Clean the air filter frequently, especially when working in dusty conditions. A clogged air filter can reduce engine performance and increase fuel consumption. Wash foam filters with warm, soapy water, rinse, and allow to dry completely before reinstallation. Paper filters should be replaced if heavily soiled.
4. Inspección de bujías
Inspect the spark plug periodically for wear, carbon buildup, or damage. Clean or replace as necessary. Ensure the electrode gap is set correctly.
5. Limpeza e almacenamento xerais
After each use, clean the chain saw thoroughly, removing sawdust, debris, and oil residue. For long-term storage, drain the fuel tank and run the engine until it stops to clear the carburetor. Store the chain saw in a dry, secure location, away from children and flammable materials.
