2. Remove the chain cover nuts and the chain cover.
3. Mount the guide bar onto the studs.
4. Carefully place the saw chain around the clutch drum and into the guide bar groove. Ensure the cutting edges of the chain are facing the correct direction.
5. Replace the chain cover and hand-tighten the nuts. Do not fully tighten yet.
6. Adjust chain tension as described in the Maintenance section.

1.3 Préparation du carburant et de l'huile de chaîne

The ECHO CS-310-16 requires a specific fuel mixture and chain lubricant for optimal performance and longevity.

• Mélange de carburant : Use fresh, unleaded gasoline mixed with ECHO-approved 2-stroke engine oil at the specified ratio (typically 50:1, but always confirm with your owner's manual). Mix thoroughly in a separate, approved fuel container.
• Huile de chaîne : Fill the chain oil tank with high-quality bar and chain oil. This lubricates the chain and guide bar during operation.

2. Mode d'emploi

Always wear appropriate personal protective equipment (PPE) including a helmet, eye protection, hearing protection, gloves, and chainsaw protective trousers/chaps. Ensure a clear work area free of bystanders and obstacles.

2.1 Démarrage de la tronçonneuse

1. Placez la tronçonneuse sur une surface plane et stable.
2. Engagez le frein de chaîne.
3. Push the primer bulb several times until fuel is visible.
4. Réglez le starter sur la position « CHOKE COMPLET ».
5. Pull the starter rope firmly and steadily until the engine "pops" or attempts to start (usually 1-3 pulls).
6. Move the choke to the "HALF CHOKE" or "RUN" position (refer to your specific model's instructions).
7. Tirez à nouveau sur la corde du lanceur jusqu'à ce que le moteur démarre.
8. Once started, let the engine warm up for a few moments, then disengage the chain brake before cutting.

2.2 Techniques de coupe de base

• Abattage: For cutting down trees, plan your escape route and make a directional notch cut followed by a felling cut.
• L'ébranchage : Éliminez les branches d'un arbre tombé. Travaillez de la base vers le sommet, en coupant d'abord les plus petites branches.
• Tronçonnage : Cut a fallen tree into sections. Be aware of tension and compression in the wood to avoid pinching the bar or kickback.
• Always maintain a firm grip with both hands and keep your body balanced.

3. Entretien

Regular maintenance ensures the longevity and safe operation of your chainsaw. Perform these checks and tasks before and after each use.

3.1 Vérifications quotidiennes

• Check chain tension: The chain should be snug against the guide bar but still able to be pulled around by hand.
• Vérifiez l'affûtage et l'état de la chaîne. Affûtez-la ou remplacez-la si nécessaire.
• Verify chain oil level and ensure the oiler is functioning.
• Clean the air filter and cooling fins.
• Vérifiez le serrage de tous les écrous, boulons et vis.

3.2 Entretien de la barre de guidage

• Nettoyez la rainure du guide-chaîne pour enlever la sciure et les débris.
• Check for burrs on the guide bar rails. File les lisser s'ils sont présents.
• Inspect the nose sprocket for wear and ensure it spins freely.
• Retournez périodiquement le guide-chaîne pour assurer une usure uniforme.

3.3 Stockage à long terme

• Vidangez tout le carburant du réservoir et faites tourner le moteur jusqu'à ce qu'il s'arrête afin de nettoyer le carburateur.
• Vidangez le réservoir d'huile de chaîne.
• Nettoyez soigneusement toute la tronçonneuse.
• Remove the spark plug, add a small amount of 2-stroke oil to the cylinder, and pull the starter rope a few times to distribute the oil. Reinstall the spark plug.
• Store the chainsaw in a dry, well-ventilated area, away from heat sources and out of reach of children.

4. Dépannage

This section addresses common issues you might encounter with your ECHO CS-310-16 Chainsaw. For more complex problems, consult a qualified service technician.

4.1 Le moteur ne démarre pas

• No Fuel/Incorrect Mixture: Ensure the fuel tank has fresh, correctly mixed fuel.
• Réglage du starter : Verify the choke is set correctly for starting (full choke for cold start, half choke after initial "pop").
• Bougie d'allumage: Check the spark plug for fouling or damage. Clean or replace if necessary.
• Moteur inondé : If the engine is flooded (too much fuel), remove the spark plug, pull the starter rope several times to clear the cylinder, and then reinstall the plug and attempt to start with the choke off.

4.2 Chain Not Cutting Effectively

• Chaîne terne : La cause la plus fréquente. Affûtez ou remplacez la chaîne.
• Tension de chaîne incorrecte : A loose or overly tight chain can affect cutting performance. Adjust tension.
• Insufficient Chain Oil: Ensure the chain oil tank is full and the oiler is working. A dry chain will not cut well and can cause damage.
• Worn Guide Bar: Check the guide bar for wear, burrs, or a worn nose sprocket. Replace if severely worn.

4.3 Engine Lacks Power

• Dirty Air Filter: A clogged air filter restricts airflow. Clean or replace it.
• Incorrect Fuel Mixture: An improper fuel-to-oil ratio can lead to poor performance.
• Pare-étincelles : A clogged spark arrestor screen in the muffler can reduce engine power. Clean it regularly.
