Advertències generals de seguretat
- Utilitzeu sempre l'equip de protecció individual (EPI) adequat, com ara ulleres de seguretat, protecció auditiva, guants i calçat resistent.
- Never operate the chain saw when fatigued, under the influence of alcohol, drugs, or medication.
- Keep bystanders, children, and animals at a safe distance from the work area.
- Inspect the chain saw before each use for any damage, loose parts, or fuel leaks.
- Ensure the chain brake is functional and engaged when starting the engine or moving between cuts.
Muntatge i muntatge
1. Desembalatge i comprovació de components
Carefully remove all components from the packaging. Verify that all parts are present and undamaged. Refer to the parts diagram (not included in this text, but typically found in a physical manual) to identify each component.
2. Fuel Mixture Preparation
This chain saw uses a 2-stroke engine and requires a specific fuel-to-oil mixture. Use high-quality unleaded gasoline and a premium 2-stroke engine oil designed for air-cooled engines. Refer to the engine manufacturer's recommendations for the exact mixing ratio (typically 25:1 or 50:1, depending on oil type). The fuel tank capacity is 560ml.
- Mix fuel in a separate, approved fuel container.
- Shake the mixture thoroughly before pouring into the fuel tank.
- Always refuel in a well-ventilated area with the engine off and cool.
3. Instal·lació de la cadena i la barra guia
- Assegureu-vos que el fre de cadena estigui activat.
- Remove the side cover by loosening the nuts.
- Place the guide bar onto the studs, ensuring the chain tensioner pin aligns with the hole in the bar.
- Carefully fit the saw chain around the sprocket and into the guide bar groove. Ensure the cutting edges of the chain are facing the correct direction. The chain pitch is 3/8in (0.325in).
- Torneu a col·locar la coberta lateral i estrenyeu les femelles a mà.
- Adjust chain tension: The chain should be snug against the guide bar but still able to be pulled freely by hand. There should be no slack on the underside of the bar.
- Estrenyeu bé les femelles de la coberta lateral.
4. Bar and Chain Oil
Fill the oil tank (capacity 260ml) with high-quality bar and chain oil. This oil lubricates the chain and guide bar during operation, reducing friction and wear. Do not use engine oil or waste oil.
Instruccions de funcionament
1. Arrencada del motor
The Tolsen chain saw features an easy starting system with an automatic choke.
- Place the chain saw on a firm, flat surface. Ensure the chain brake is engaged.
- Premeu la bombeta d'encebament diverses vegades fins que el combustible sigui visible.
- Col·loqueu la palanca de l'estrangulador a la posició "ESTRANGULADOR COMPLET".
- Estireu el cordó d'arrencada amb fermesa i constantment fins que el motor s'encengui (normalment unes quantes estirades).
- Once the engine fires, immediately push the choke lever to the "HALF CHOKE" or "RUN" position.
- Estireu de nou el cordó d'arrencada fins que el motor arrenqui i funcioni suaument.
- Allow the engine to warm up for a few moments at idling speed (3200rpm ±5%).
- Disengage the chain brake before beginning cutting operations.
2. Operating Safety Features
- Safety Throttle Lever: This lever prevents accidental acceleration. It must be depressed along with the main throttle trigger to engage the engine.
- Rapid Reaction Chain Brake: The chain brake is a crucial safety device designed to stop the chain instantly in the event of kickback or other emergencies. Always ensure it is functional before use.
3. Tècniques de tall
Always maintain a firm grip with both hands on the chain saw handles. Stand with your feet apart for good balance. Plan your cuts to avoid kickback and ensure the tree or limb falls in the intended direction.
Figura 2: Tolsen 20in Gasoline Chain Saw positioned for operation. This image illustrates the chain saw ready for use on the ground, demonstrating its practical application.
- Talla: Involves making a notch cut and a felling cut to direct the tree's fall. Requires careful planning and assessment of the tree's lean and surrounding area.
- Limbing: Removing branches from a felled tree. Work from the base of the tree towards the top, cutting smaller branches first.
- Enganxament: Cutting a felled tree into sections. Support the log to prevent pinching the chain.
WARNING: Be aware of kickback. Kickback occurs when the moving chain at the tip of the guide bar contacts an object, or when the wood closes in and pinches the saw chain in the cut. This can cause a rapid, uncontrolled upward and backward movement of the guide bar towards the operator.
Manteniment
Regular maintenance ensures the longevity and safe operation of your chain saw. Always ensure the engine is off and cool, and the spark plug cap is disconnected before performing any maintenance.
1. Neteja del filtre d'aire
The chain saw is equipped with a long-life air filter that can be cleaned repeatedly. A dirty air filter reduces engine performance and increases fuel consumption.
- Traieu la coberta del filtre d'aire.
- Traieu amb cura l'element del filtre d'aire.
- Clean the filter by tapping it gently or using compressed air. For heavily soiled filters, wash with warm soapy water, rinse thoroughly, and allow to dry completely before reinstallation.
- Reinstall the dry air filter and secure the cover.
2. Chain Sharpening and Tension
- Afilat: A sharp chain is crucial for efficient and safe cutting. Sharpen the chain regularly using a round file of the correct diameter for the chain pitch (3/8in or 0.325in). Follow the manufacturer's recommended sharpening angles.
- Tensió: Check chain tension frequently. A properly tensioned chain should be snug against the guide bar but still allow you to pull it around the bar by hand. Adjust as needed.
3. Inspecció de bugies
Inspect the spark plug periodically. Clean any carbon deposits and check the electrode gap. Replace the spark plug if it is fouled or worn.
4. Neteja general
After each use, clean the chain saw thoroughly. Remove sawdust, debris, and oil residue from the engine fins, air intake, and around the chain and guide bar. This prevents overheating and ensures proper operation.
