Nastavení
1. Nabíjení baterie
Before first use, fully charge the 40V 2.0Ah battery using the included charger. Insert the battery into the charger until it clicks into place. The charger's indicator light will show the charging status. Refer to the charger's specific instructions for detailed light indications and charging times.
2. Bar and Chain Assembly
Ensure the battery is removed from the chainsaw before assembly. Carefully unpackage the guide bar and saw chain. Place the saw chain around the drive sprocket and guide bar, ensuring the cutting edges face the correct direction (away from the chainsaw body on the top side of the bar). Align the guide bar with the mounting studs on the chainsaw body. Reattach the side cover and secure it using the tool-less tensioning knob.
3. Plnění nádržky na řetězový olej
Locate the oil reservoir cap on the chainsaw body. Unscrew the cap and fill the reservoir with high-quality bar and chain oil. Monitor the oil level through the transparent oil fill window. Do not overfill. Securely replace the cap. The automatic oiler will lubricate the chain during operation.

4. Nastavení napnutí řetězu
Proper chain tension is crucial for safe and efficient operation. With the battery removed, use the tool-less tensioning knob to adjust the chain. The chain should be snug against the guide bar but still allow you to pull it freely by hand. A properly tensioned chain will not sag on the underside of the guide bar. Over-tightening can cause premature wear; too loose can cause the chain to derail.

Návod k obsluze
1. Spuštění řetězové pily
Insert a fully charged battery into the chainsaw until it locks into place. Hold the chainsaw firmly with both hands. Engage the safety switch (usually a button or lever that needs to be pressed simultaneously with the trigger). Press the trigger to start the chain. Release the trigger to stop the chain.
2. Techniky řezání
Always maintain a firm grip on the chainsaw. Begin cutting with the bottom of the guide bar, allowing the chain to do the work. Avoid forcing the saw. For branches, cut from the top down to prevent pinching. For larger limbs, make an undercut first to prevent splintering. The 12" bar is suitable for cutting trees and limbs up to 8 inches in diameter.

Údržba
1. Mazání řetězu
Regularly check the chain oil level and refill as needed. The automatic oiler ensures continuous lubrication during use, but manual checks are essential. Use only recommended bar and chain oil.
2. Broušení řetězu
A sharp chain is vital for safe and efficient cutting. Sharpen the chain regularly or replace it when dull. A 5/32" chainsaw file is typically recommended for sharpening this chain. Consult a professional if you are unsure about sharpening procedures.
3. Čištění
After each use, remove the battery and clean the chainsaw. Remove any sawdust, chips, and resin buildup from the guide bar, chain, and motor housing. Ensure ventilation openings are clear. Use a soft brush or cloth; avoid harsh chemicals.
