Quick guide from the manual

The Princess Auto 20V Cordless Grass Trimmer is designed for trimming lawn edges and cutting grass around shrubs and trees. Note: The battery and charger are sold separately. Always read the safety instructions before use, wear appropriate personal protective equipment (impact safety goggles, gloves, non-skid footwear), and ensure the work area is clear of bystanders.

Assembly & Installation

Follow these steps to assemble the trimmer:

Edging Wheel: Fit the edging wheel onto the left side under the motor housing. Secure it with two screws.
Safety Guard: Flip the trimmer head upside down. Slide the safety guard's slot under the trimmer line spool until seated. Secure with a screw.
Wire Guide: Spread the wire guide ends and slip them into the side openings of the safety guard until they snap into place.
Front Handle: Push the handle ends onto the frame's mount. Insert a bolt through the handle and mount, then secure with the adjustment knob and nut.

Operation

Before operating, ensure the battery is charged and installed by aligning the rib on the battery with the groove on the port until it clicks.

Trimming

Adjust the trimmer head angle and extension tube length for a comfortable, straight-backed posture.
Hold the trimmer head off the ground.
Push the trigger lock button, then squeeze the trigger to start the motor.
Move the trimmer slowly side to side while walking forward.

Edge Trimming

Adjust the trimmer head angle to be in-line with the extension tube.
Twist the head until the edging wheel is at a 90-degree angle to the handle.
Place the wheel on the ground and align the trimmer line with the lawn's edge.

Line Feed

The trimmer features automatic line feed. If the line breaks, you can manually pull additional line by removing the battery, flipping the head, and pressing the small button on the spool head while pulling the line out.

Care & Maintenance

Cleaning: Keep the tool clean, dry, and free of oil/grease. Remove grass and debris from ventilation slots.
Replacing Trimming Line: Use 1.3, 1.4, or 1.5 mm nylon line. Remove the spool cover, discard old line, and wind 5 meters (16 feet) of new line onto the spool in the direction of the arrow. Ensure lines do not overlap.
Storage: Remove the battery. Clean the exterior. If storing for an extended period, apply a thin coat of lubricant to steel parts to prevent rust.
