2. Important Safety Instructions

WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

General Chainsaw Safety

• Always wear appropriate personal protective equipment (PPE) including safety glasses, hearing protection, gloves, and sturdy footwear.
• Keep children and bystanders away while operating a chainsaw.
• Do not operate a chainsaw when you are tired, under the influence of drugs, alcohol, or medication.
• Inspect the chainsaw before each use for damaged parts, loose fasteners, or any other condition that may affect its safe operation.
• Ensure the work area is clear of obstacles and well-lit.
• Avoid cutting small brush and saplings that may catch the chain and be whipped toward you or pull you off balance.
• Be aware of kickback. Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.

Battery Safety

• Use only the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another.
• Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 130°C (265°F) may cause explosion.
• Follow all charging instructions and do not charge the battery pack or appliance outside of the temperature range specified in the instructions.

4. Always charge batteries in a well-ventilated area and away from flammable materials.

5.2 Installing the Guide Bar and Chain

1. Ensure the battery is removed from the chainsaw.
2. Place the chain around the sprocket and guide bar, ensuring the cutting edges of the chain are facing the correct direction (refer to arrows on the chain and guide bar).
3. Align the guide bar with the mounting studs on the chainsaw body.
4. Carefully place the chain over the drive sprocket.
5. Reinstall the side cover and hand-tighten the tool-free tension knob. Do not fully tighten yet.

5.3 Adjusting Chain Tension

1. With the side cover loosely attached, use the tool-free tension knob to adjust the chain tension.
2. 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.
3. Once the tension is correct, fully tighten the tool-free tension knob to secure the guide bar and chain.
4. Periodically check chain tension during operation, especially during the first hour of use, as new chains can stretch.

5.4 Adding Chain Oil

1. Ensure the battery is removed.
2. Locate the oil tank cap (refer to Figure 4.4).
3. Unscrew the cap and fill the reservoir with high-quality bar and chain oil. Do not use waste oil or motor oil.
4. Replace the cap securely.
5. The chainsaw features an auto oiling system for continuous lubrication during operation. Regularly check the oil level.

4. Press the safety lock button with your thumb.
5. While holding the safety lock button, squeeze the trigger switch to start the chainsaw. Release the safety lock button once the chainsaw starts.

6.2 Cutting Techniques

• Always stand firmly with your weight balanced on both feet.
