6.1 Powering On/Off
- To Power On: Insert the battery. Press and hold the power switch until you hear a single beep. The LCD display will illuminate.
- To Activate Blades: After powering on, quickly press the trigger twice. The blades will open, indicating readiness for use.
- To Power Off: Press and hold the power switch until you hear a long beep. The blades will close and lock, and the LCD display will turn off.
6.2 Adjusting Cutting Diameter
The shears offer four adjustable cutting diameters: 10mm, 20mm, 30mm, and 40mm. The default maximum cutting diameter is 40mm upon activation.

To change the cutting diameter, simply press the power button briefly while the shears are active. Each press will cycle through the available sizes (40mm > 30mm > 20mm > 10mm > 40mm).
6.3 Pruning Techniques
Position the branch to be cut fully within the blades. Press the trigger to make a clean cut. Avoid forcing the shears on branches exceeding the maximum cutting diameter.

7.1 Blade Cleaning and Lubrication
After each use, especially after cutting resinous wood, clean the blades to prevent sap buildup and corrosion.

- Ensure the shears are powered off and the battery is removed.
- Use a damp cloth to wipe off any sap, dirt, or debris from the blades. For stubborn residue, use a blade cleaner or rubbing alcohol.
- Once clean and dry, apply a few drops of light machine oil to the pivot point and along the cutting edge of the blade. Open and close the blades a few times to distribute the oil.
7.2 Blade Sharpening
Use the provided sharpening stone to maintain blade sharpness. Sharpen only the beveled edge of the blade.
- Ensure the shears are powered off and the battery is removed.
- Hold the sharpening stone at the original blade angle and gently rub it along the cutting edge in one direction.
- Repeat several times until the blade is sharp.
7.3 Blade Replacement
If the blade becomes dull or damaged beyond sharpening, replace it with the provided spare blade or an original SeeSii replacement blade.
- Ensure the shears are powered off and the battery is removed.
- Using the provided wrench, carefully loosen the nut holding the blade in place.
- Remove the old blade and replace it with the new one, ensuring proper alignment.
- Tighten the nut securely.
7.4 Battery Care and Storage
- Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
- For long-term storage, charge batteries to approximately 50% capacity.
- Recharge batteries every 3-6 months during long storage periods to prevent deep discharge.
7.5 Storage of Shears
When not in use, store the pruning shears in their carrying case in a dry, secure location, out of reach of children.
