Setup

1. Battery Charging

Before first use, fully charge the 40V max XGT Lithium-Ion 5.0Ah battery using the provided rapid optimum charger.

1. Connect the rapid optimum charger to a power outlet.
2. Slide the battery into the charger until it clicks into place.
3. The charger's indicator lights will show the charging status. Refer to the charger's manual for specific light patterns.
4. Once fully charged, remove the battery from the charger.

2. Guide Bar and Saw Chain Installation

Ensure the battery is removed from the chain saw before installation.

1. Place the chain saw on a stable, flat surface.
2. Loosen the side cover nuts and remove the side cover.
3. Carefully place the saw chain around the sprocket and guide bar, ensuring the cutting edges are facing the correct direction (refer to chain markings).
4. Fit the guide bar onto the chain saw studs, aligning the chain tension pin with the hole in the guide bar.
5. Replace the side cover and hand-tighten the nuts. Do not fully tighten yet.
6. Adjust chain tension using the tool-less chain adjustment knob. The chain should be snug but still able to be pulled freely around the guide bar by hand.
7. Once tension is correct, fully tighten the side cover nuts.

2. Cutting Techniques

• Always maintain a balanced stance and firm grip.
• Allow the chain to reach full speed before contacting the wood.
• Apply steady, even pressure. Do not force the saw.
• Be mindful of the Active Feedback-Sensing Technology (AFT) which will shut off the motor if the chain rotation is suddenly stopped.
• For felling trees, follow proper notching and felling procedures. For limbing, work from the bottom up, keeping the trunk between you and the branch.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your chain saw.

1. Chain Sharpening and Replacement

• A dull chain can lead to poor cutting performance and increased kickback risk. Sharpen the chain regularly using a round file of the correct diameter (refer to chain specifications).
• Replace the chain when it becomes excessively dull, damaged, or stretched beyond adjustment limits.

2. Guide Bar Maintenance

• Clean the guide bar groove regularly to remove sawdust and debris.
• Flip the guide bar periodically to ensure even wear.
• Check the guide bar for burrs or damage and file them smooth if necessary.

3. Cleaning

• After each use, clean the chain saw thoroughly, especially the chain, guide bar, and sprocket area, to remove sawdust, sap, and debris.
• Use a brush or compressed air. Do not use water to clean the electrical components.

4. Storage

• Store the chain saw in a dry, secure location, out of reach of children.
• Remove the battery before long-term storage.
• Apply a light coat of oil to the chain and guide bar to prevent rust.
