Oil on the lead screw nut 

Please oil on the lead screw nut after pruning shear is on working 7 days or shear force is reduced significantly. Please see the following 

steps:

 

 

 

Cautions 

1.

 

Before charging, please ensure battery power switch is in OFF position. During charging, it is normal for the charger and battery to 

be warm. 

2.

 

If the battery is not use for a long period of time, it recommended to charge the battery once every 3 months, this is to ensure the 

battery life is not affected by low usage. 

3.

 

For new battery or battery unused for a long time, it will need about 5 charge-discharge cycles before achieving full capacity. 

4.

 

Do not recharge a fully charged battery just after a few minutes of usage, this will reduce the battery lifespan and efficiency. 

5.

 

Do not use a damaged battery and do not disassemble the charger or battery. 

6.

 

Do not place battery near high temperature heat source, the battery will explode in fire or long exposure to high temperature heat 

source. 

7.

 

Do not charge the battery in outdoor or humid environment. 

8.

 

It is normal for the pruning shear to reduce cutting diameter when the battery capacity is getting low. 

9.

 

Do not use the pruning shear during charging. It must be disconnected from the battery during charging. 

10.

 

Do not store the battery in a humid environment. 

 

Blade Replacement 

When the moving blade no longer crosses the fixed blade throughout its length, or when the power pruner could no longer have a clean 

cut after grinding, blade replacement is recommended with the following steps: 

1. For safety, before replacing the blade, please ensure the pruning shear is power OFF and power cable disconnected from the battery. 

2. Refer to the diagrams below on the procedure to replace the blade. 

3. Clean up the blade after replacing, connect to power cable to battery, power ON to test the blade, close up the blade to complete the 

whole procedure. 

* Fixed and movable blades can be replaced 

individually; do not worry about the size of the 

replacement blade aperture, the opening will 

automatically return to normal size during power 

ON after completing blade replacement. 

 

 

Operation Precautions 

Usage and Care for Pruning Shear 

1. Do not cut branches beyond the specified diameter indicated, do not cut hard items such as metals, stone or any other 

non-plant materials. If the blades are worn or damaged, please replace the blades. 

2. Keep the pruning shear clean, use a clean cloth to clean the pruning shear, battery and charger (do not use any abrasive or 

solvent-based cleaning agent), use a soft brush or a dry to clean the dust off the pruning shear head.
