Setup
Before initial use, ensure the tool is properly assembled and the battery is charged.
- Battery Installation: Align the fully charged HART 20V battery pack with the battery port on the tool. Slide the battery into place until it clicks securely. Ensure it is firmly seated.
- Chain Tensioning: This pruning saw features tool-less chain tensioning. Locate the tensioning knob or lever on the side of the saw. Follow the instructions in the included Assembly Guide to adjust the chain tension. The chain should be snug but still able to be pulled freely around the guide bar by hand.
- Chain Guard: Ensure the front chain guard is securely in place. This guard helps reduce kickback and protects the user.

Operating Instructions
Follow these steps for safe and effective operation of your pruning saw.
- Pre-Operation Check: Before each use, inspect the tool for any damage, loose parts, or worn components. Ensure the chain is sharp and properly tensioned. Verify the battery is fully charged.
- Starting the Tool: With both hands firmly gripping the handles, depress the safety lock-out button (if present) and then squeeze the trigger switch to start the motor. The chain will begin to move.
- Pruning Technique: Position the saw with the bottom of the guide bar against the branch to be cut. Allow the saw to do the work; do not force it. Make smooth, controlled cuts. For larger branches, make a relief cut on the underside first to prevent tearing.
- Stopping the Tool: Release the trigger switch to stop the motor and chain movement. Always wait for the chain to come to a complete stop before setting the tool down.
- Oil-Free Operation: This pruning saw is designed for oil-free operation, eliminating the need for messy chain oil maintenance.
Maintenance
Regular maintenance ensures the longevity and safe operation of your pruning saw.
- Cleaning: After each use, remove the battery pack and use a brush or compressed air to clean sawdust, chips, and debris from the tool, especially around the chain, guide bar, and motor vents.
- Chain Inspection: Regularly inspect the chain for sharpness, damage, or excessive wear. A dull chain can lead to poor performance and increased kickback risk. Sharpen or replace the chain as needed.
- Guide Bar Maintenance: Check the guide bar for burrs or wear. Clean the guide bar groove to ensure smooth chain movement.
- Storage: When not in use, store the pruning saw with the scabbard (blade cover) installed in a dry, secure location out of reach of children. Remove the battery pack before storing for extended periods.
