Setup
1. Battery Installation (Battery and Charger Sold Separately)
- Ensure the pruning shear is turned off.
- Align the 20V WORX Power Share battery pack (not included) with the battery port on the tool's handle.
- Slide the battery pack into the port until it clicks securely into place. Ensure it is fully seated to prevent accidental disconnection during operation.
2. Initial Inspection
- Before each use, inspect the blades for any damage, dullness, or debris.
- Check that all fasteners are tight and that the tool is in good working condition.

Operating Instructions
1. Powering On and Off
- To Power On: Hold the Safety Lock Trigger and then depress the On/Off trigger. A green LED will illuminate, and the blades will open to their maximum position, indicating the tool is ready for use.
- To Power Off: Depress and hold the On/Off trigger until you hear two beeps. The blades will close, and the pruner will turn off.
2. Cutting Operation
- The pruning shear is designed to cut branches up to 1 inch in diameter with ease.
- For branches slightly larger than 1 inch (e.g., up to 1.5 inches), multiple cuts may be required. If the pruner encounters resistance, it may beep once and the blades will open. Release and depress the On/Off trigger to reset and continue cutting.
- Position the branch deep into the blades for a clean, efficient cut.
3. Blade Settings
- The blades have two settings for opening width. For smaller branches, depress the On/Off trigger and hold until you hear one beep. The blades will then open to a smaller cutting size, which can be more efficient for lighter pruning tasks.
4. One-Handed Operation
The compact and lightweight design allows for comfortable one-handed operation, making it easier to reach and prune in various positions.

5. Automatic Shut-Off
If the pruner remains inactive for approximately one minute while in the open position, it will automatically shut off to conserve battery power. To reactivate, depress the Safety Lock Trigger and On/Off trigger.
Maintenance
1. Blade Cleaning and Lubrication
- After each use, disconnect the battery and clean the blades to remove sap, debris, and plant residue. Use a damp cloth and mild detergent if necessary.
- Periodically lubricate the blades and the small ball bearing mechanism (visible on one side of the blades) with one or two drops of oil. This helps maintain smooth operation and protects against rust, especially with the titanium coating.
2. Blade Replacement
While the titanium-plated blades are designed for durability, they may eventually require replacement. Please note that replacement blades for the WORX WG330.9 model may not be readily available. Contact WORX customer support for assistance with blade maintenance or replacement options.
3. Storage
- Store the pruning shear in a dry, secure location, out of reach of children.
- Ensure the blades are closed and the battery is removed before storage.
