3. Setup

3.1 Unpacking and Component Identification

Carefully remove all components from the packaging. Verify that all parts listed in the Product Overview section are present.

This video provides a step-by-step guide on assembling the Litheli U20 pole saw, including connecting the poles, installing the chain, and preparing the saw for use.

3.2 Pole Assembly

1. Align the notch on the front pole with the arrow mark on the rear pole.
2. Push the poles together until they click into place.
3. Tighten the sleeve in the marked direction to secure the connection.
4. If using the extension pole, repeat the alignment and tightening steps to connect it between the front and rear poles.

3.3 Chain and Bar Installation

1. Remove the chain cover by turning the locking knob counter-clockwise.
2. Install the saw chain onto the guide bar, ensuring the cutting teeth are oriented in the correct rotation direction (indicated by a symbol on the bar).
3. Fit the chain and bar assembly onto the drive sprocket of the saw head.
4. Replace the chain cover and tighten the locking knob clockwise.
5. Adjust the chain tension by turning the tensioning sleeve. The chain should be snug but still able to be pulled slightly away from the bar.

This image illustrates the tool-free chain tensioning system, allowing for easy adjustment of the chain's tightness by rotating a knob.

3.4 Oiling the Chain

The pole saw is equipped with an automatic lubrication system. Ensure the oil reservoir is filled before use.

1. Unscrew the oiler tap located on the saw head.
2. Fill the reservoir with appropriate bar and chain oil. Do not overfill.
3. Securely screw the oiler tap back into place.

This image shows the transparent oil reservoir and the process of filling it with bar and chain oil, highlighting the automatic lubrication feature.

3.5 Battery Installation

1. Ensure the battery is fully charged using the provided 65W charger.
2. Press the button on the battery compartment to release the cover.
3. Insert the 2.0Ah U-Battery Plus into the compartment until it clicks securely into place.

4. Operating Instructions

4.1 Starting the Pole Saw

To start the tool, simultaneously press the safety lock-off button and the trigger switch. Release the lock-off button once the saw starts.

4.2 Cutting Techniques

• Stance: Maintain a balanced stance with feet shoulder-width apart.
• Branch Size: Begin with smaller branches. For larger branches, make an undercut first to prevent bark stripping.
• Cutting Motion: Allow the saw to do the work. Do not force the saw through the branch.
• Avoid Kickback: Do not cut with the tip of the guide bar. Be aware of the branch's tension and direction of fall.

5. Maintenance

5.1 Chain Tension

Regularly check chain tension. A properly tensioned chain should be snug against the guide bar but still allow you to pull it away slightly. Adjust using the tool-free tensioning knob as needed.

5.2 Chain Lubrication

Monitor the oil level in the reservoir and refill with bar and chain oil when necessary. The automatic oiling system ensures continuous lubrication during operation.

5.3 Cleaning

After each use, clean the guide bar, chain, and saw head to remove sawdust, sap, and debris. Ensure the air vents are clear to prevent overheating.

5.4 Battery Care

Store batteries in a cool, dry place. Charge batteries fully before storage and periodically during long storage periods to maintain battery health.

6. Troubleshooting

• Saw Not Starting: Check if the battery is fully charged and properly inserted. Ensure both the lock-off button and trigger switch are pressed simultaneously.
• Poor Cutting Performance: Verify chain tension. Inspect the chain for dullness or damage; sharpen or replace if necessary. Ensure the oil reservoir is filled.
• Excessive Vibration: Check for loose components or a damaged chain/bar.
• Oil Leakage: Ensure the oiler tap is securely closed. Inspect the reservoir for cracks or damage.
