3.3. Chain Tension Adjustment

Proper chain tension is crucial for safe and effective cutting. The G40PS20 features tool-free chain tension adjustment.

1. Ensure the battery is removed before adjusting the chain.
2. Locate the chain tensioning knob on the side of the cutting head.
3. Turn the knob to adjust the chain tension. The chain should be snug against the guide bar but still able to be pulled around by hand.
4. Refer to the diagram for visual guidance.

3.4. Chain Lubrication

The pole saw features an automatic chain lubrication system. It is essential to keep the oil reservoir filled with appropriate chain oil.

1. Before each use, check the oil level in the reservoir.
2. Unscrew the oil cap and fill the reservoir with high-quality chain and bar oil.
3. Replace the cap securely. The automatic system will lubricate the chain during operation.

4. Operating Instructions

Follow these guidelines for safe and effective operation of your Greenworks G40PS20 pole saw.

4.1. Starting and Stopping the Pole Saw

2. To start, press and hold the safety lock-out button, then squeeze the trigger switch.
3. To stop, release the trigger switch.

4.2. Adjusting Pole Length

The pole saw features an extendable aluminum shaft for reaching high branches.

1. Loosen the locking collar(s) on the pole.

4.3. Cutting Techniques

Always maintain a firm grip and stable stance. Plan your cuts to ensure branches fall safely and away from you.

• Undercut first: For larger branches, make a small undercut on the underside of the branch first to prevent bark stripping.
• Top cut: Then make the main cut from the top, slightly further out from the undercut.
• Final cut: After the main weight of the branch has fallen, make a final clean cut closer to the main trunk or limb.
• Avoid binding: Do not force the saw. Let the chain do the work. If the chain binds, release the trigger and free the saw.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your pole saw.

• Clean after each use: Remove sawdust, debris, and sap from the guide bar, chain, and motor housing.
• Check chain tension: Regularly inspect and adjust chain tension. A loose chain can derail and cause injury.
• Monitor oil level: Ensure the automatic oiler reservoir is always filled with appropriate chain oil.
• Sharpen or replace chain: A dull chain reduces cutting efficiency and increases strain on the motor. Sharpen or replace the chain as needed.
• Store properly: When not in use, disassemble the pole saw into its 3 parts for easy transport and space-saving storage. Store in a dry, secure location out of reach of children.
