5. Uppsetning

Before operating your chainsaw, follow these steps to ensure it is properly set up and ready for use.

• Stingdu hleðslutækinu í venjulegt rafmagnsinnstungu.
• Allow the batteries to charge fully before first use. The charger will indicate when charging is complete (refer to charger's indicator lights). A full charge typically takes approximately 2 hours per battery.

5.2 Chain Installation & Tensioning

The chainsaw comes with the guide bar and chain pre-installed, but it's crucial to check and adjust the tension before use.

• Gakktu úr skugga um að rafhlaðan sé fjarlægð úr keðjusöginni.
• Finndu keðjuspennuhnappinn á hlið keðjusögarinnar.
• Turn the knob to adjust the 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 guide bar.
• Periodically check chain tension during operation, especially during the first few uses, as new chains can stretch.

5.3 Adding Bar & Chain Oil

• Gakktu úr skugga um að rafhlaðan sé fjarlægð.
• Locate the oil tank cover on the chainsaw.
• Unscrew the cover and fill the oil tank with high-quality bar and chain oil. Do not use motor oil or other lubricants, as they may damage the automatic oiling system.
• Replace the oil tank cover securely.
• Check the oil level regularly during operation and refill as needed. The automatic oiling system requires a constant supply of oil to function correctly.

6. Notkunarleiðbeiningar

Follow these instructions for safe and effective operation of your SEYVUM chainsaw.

6.1 Ræsing á keðjusöginni

• Gakktu úr skugga um að rafhlaðan sé fullhlaðin og örugglega sett í keðjusögina.

• While holding the safety switch, squeeze the main switch (trigger) to start the chainsaw. The chain will begin to move.

6.2 Skurðartækni

Always exercise caution and follow safe cutting practices.

• Liming: When cutting branches, ensure the branch is stable. Cut from the top down to avoid pinching the bar.
• Bucking: When cutting logs, ensure the log is securely supported. If cutting a log on the ground, avoid cutting into the ground, which can dull the chain.
• Forðastu að klípa: Be aware of the direction of pressure on the wood. If the wood closes on the chain, it can pinch the bar and stop the saw.
• Bakslagsforvarnir: Always be aware of the guide bar tip. Avoid contact with the tip, as this is the primary cause of kickback.
