Frequently Asked Questions
How do I set up a base station?
1.Confirm that the boundary line has been laid: Ensure that the boundary line of the designated work area for the robot (usually wires buried underground or fixed on the ground) has been correctly installed and powered on.
2.Cleaning the lawn: Before starting for the first time, remove stones, branches, toys, and other debris from the lawn to prevent damage to the machine or jamming.
3.Check the body: Ensure that the robot is not significantly damaged and the blades are securely installed (if it is being used for the first time).
Do I need to install underground boundary wires before using the robot?
No. FJD robots do not rely on buried wires.
Boundaries are drawn digitally in the app by walking or driving the perimeter once.
What types of grass can the robotic mower work on?
The mower is suitable for a wide range of turf environments including:
- Residential lawns
- Commercial green areas such as sports fields and stadiums
- Parks, campuses and public open spaces
-
A variety of turfgrass species, including but not limited to:
Bermuda grass, Tall fescue, Kentucky bluegrass, Bentgrass, Zoysia grass, Perennial ryegrass...
Can an autonomous mower operate safely around sprinkler heads?
Yes. The mower can work as usual on lawns with sprinkler heads.
When approaching a sprinkler, the vision sensor will detect and avoid it automatically.
How can the mower cut tall grass instead of treating it as an obstacle?
Pre-cut tall or overgrown grass manually or using larger equipment.
Once the turf height is reduced to a manageable level, the autonomous mower can be deployed for regular maintenance.
How precise are FJD line-marking robots?
When operating under RTK corrections, marking accuracy typically falls within ±2–3 cm, suitable for FIFA/IAAF-level field geometry.
What are the installation requirements for the RTK base station?
Place the base station in a location that is:
- In an open area
- As high as possible
- With clear, unobstructed line of sight to the robot
- Firmly fixed so it will not move
- Easily accessed for wired power supply
What are the installation requirements for the charging dock?
Install the dock:
- On flat ground
- With at least 2 m of clearance in front and 1.5 m on each side
- With grass height below 5 cm (approx. 2 inches) beneath the dock
- Not too close to a wall or vertical obstruction
- With convenient access to wired power
Can the RTK base station and the charging dock be relocated?
Yes.
However, after relocating it, all related items such as task boundaries and the charging dock position must be reset or re-marked in the software.
Are there any precautions to take when maintaining or cleaning the robot?
- Switch off the mower first;
- Wear work shoes, long pants, and gloves for cleaning. Do not clean while barefoot or in exposed sandals for safety.
- Clean the exterior of the mower thoroughly with a soft brush or cloth. Do not clean with alcohol, petrol, acetone or other corrosive/volatile solvents as they may damage the exterior and interior of the mower;
- For proper docking, regularly inspect and clean the charging station of debris and mud. Ensure that all connecting parts of the charging station, extension cables, and power supply are not obstructed;
- Check the baseplate and blades, do not use a hose to rinse them, and wipe them gently. Make sure that the blade disc rotates freely and the blades pivot freely when cleaning is complete;
- Check the wheels regularly to see if they are stuck, clean off the mud and lubricate the wheels;
- Clean the camera module to avoid any blockage in image visual positioning and visual recognition function;
- After all cleanings are completed, start the mower. If it can start up and operate normally, the cleaning work is completed.
How should the equipment be stored long-term, especially during winter?
- Store the base station, charging dock, and robot indoors at normal room temperature.
- Remove the robot’s battery and store it at 30–60% charge before long-term storage.
How should I handle damaged parts?
- For items within warranty, send the damaged component to your local dealer—replacement or repair will be arranged through the dealer and manufacturer.
- For items not covered under warranty, purchase spare parts from an authorized dealer and replace them as needed.
Do I need to clear grass from inside the mower after every job? How often should I clean it?
- In most cases, cleaning is not required after every job.
- However, if grass buildup begins to block the cutting chamber or prevent the blades from turning, the mower should be cleaned promptly.
How can I provide feedback or report an issue?
You may report issues through any of the following channels:
- Contact your local FJD dealer
- Submit feedback via the official FJD website
- Use the feedback and support interface direact your local FJD dealer.
What should I do if I can't use the product after installing it?
- Watch the installation video;
- Assemble the mower and operate it as instructed in the video;
- If the mower can't operate normally, follow the prompts on the APP to troubleshoot;
- If the problem persists, download the error log from the APP and upload it to the manufacturer for remote debugging;
- If the remote debugging doesn’t work, contact your local distributor for on-site inspection of the mower;
- If the problem persists after trying all methods above, you can request for return & replacement of the mower.
