4. Setup

4.1 Battery Installation

This saw operates on the Milwaukee M18 REDLITHIUM battery system. Ensure the battery is fully charged before use.

1. Align the battery pack with the battery port on the saw.
2. Slide the battery pack into the port until it clicks securely into place.
3. To remove, press the release button on the battery pack and slide it out.

4.2 Chain Oil Filling

The saw features an automatic oiling system. It is crucial to fill the bar and chain oil reservoir before each use to ensure proper lubrication and prevent damage.

1. Locate the oil cap on the top of the saw.
2. Unscrew the oil cap and carefully pour bar and chain oil into the reservoir. The clear plastic window allows you to monitor the oil level.
3. Fill the reservoir to the indicated maximum level.
4. Securely replace the oil cap.
5. After filling, hold the trigger for 30 seconds before cutting to prime the oiling system.

4.3 Chain Tension Adjustment

Correct chain tension is vital for safe and efficient operation. The saw includes a convenient onboard tool for adjustments.

1. Locate the included multi-tool, typically stored within the saw's housing.
2. Use the 13mm wrench end of the tool to loosen the nut securing the bar.
3. Use the screwdriver end of the tool to turn the tensioning screw (located near the bar) to adjust the chain tension. The chain should be snug against the bar but still able to be pulled freely by hand.
4. Once tension is correct, tighten the bar nut firmly with the 13mm wrench.

4.4 Protective Sheath

A protective sheath is provided to cover the bar and chain when the saw is not in use. Always install the sheath to prevent accidental contact with the sharp chain and to protect the bar from damage.

5. Operating Instructions

5.1 Starting and Stopping

1. Starting: Press and hold the safety trigger (located on the handle) with your thumb, then squeeze the main trigger to start the saw. The saw is designed for ambidextrous use, with the safety trigger accessible from either side.
2. Stopping: Release the main trigger to stop the saw. The safety trigger will automatically reset.

5.2 Cutting Techniques

The 8-inch bar is ideal for pruning branches up to 6-8 inches in diameter. For optimal results and safety:

• Let the Saw Do the Work: Avoid forcing the saw through the wood. Apply light pressure and allow the chain to cut naturally.
• Maintain Control: Keep a firm grip on the saw. For larger branches, consider using two hands, ensuring your second hand is inside the knuckle guard around the saw motor body.
• Avoid Kickback: Be aware of the kickback zone (the tip of the bar). Avoid cutting with the tip and ensure the chain is not pinched in the cut.
• Cutting Small Branches: For branches under 1/2 inch, the saw chain may cause the limb to jump. Exercise caution and secure the branch if possible.

6. Maintenance

6.1 General Cleaning

Regular cleaning helps maintain performance and longevity.

• Remove the battery pack before cleaning.
• Use a brush or compressed air to clear sawdust, leaves, and debris from the motor housing, chain, and bar.
• Periodically remove the bar and chain to clean the drive sprocket area.

6.2 Chain and Bar Care

• Chain Tension: Check chain tension regularly, especially during initial use as new chains may stretch. Adjust as needed using the onboard tool.
• Bar Oil: Always ensure the bar oil reservoir is adequately filled. The automatic oiling system requires a constant supply of oil.
• Chain Sharpening/Replacement: A dull chain will reduce cutting efficiency and increase strain on the motor. Sharpen or replace the chain as necessary.

6.3 Storage

When storing the saw:

• Remove the battery pack.
• Clean the saw thoroughly.
• Install the protective bar sheath.
• If storing with chain oil, lay the saw on its side with the fill port facing up to minimize leakage.
• Store in a dry, secure location out of reach of children.
