Follow the YUKA SOP from rear-shell access through mainboard replacement, cable reconnection and reassembly.
Power off, remove the security key and wear protective gloves before starting.
Before you start
Preparation
For YUKA hardware matching the supplied January 2025 SOP. Check the actual component and connector arrangement before fitting a replacement.
Keep the mower off with its security key removed throughout mechanical work. Protect disconnected power contacts and record cable positions.
Keep fasteners from each cover, bracket and board separate, and preserve the original seals and cable routes.
Tools & supplies
H3, H2 and H1.5 drivers as listed by the module SOP
Cable-tie cutters and a replacement tie
Heat gun with approved settings
UV glue F.J.JS.000014000 and UV curing lamp
Separate hardware trays, protective gloves and a camera for cable records
Source & repair notes
References use physical PDF pages, starting with the first PDF page as page 1.
The mainboard and drive-board routes use different inner covers and fastener groups. Follow the selected repair’s illustrated positions.
The tool-list entry “Electric Screwdriver (5Nm)” identifies the listed tool. It is not a per-fastener tightening specification; do not apply 5 N·m to every screw.
Editorial preparation, replacement matching and final checks are identified separately from source operations. Undocumented connector pinouts, compatibility, torque and commissioning must be confirmed for the actual hardware.

Power off and prepare the mower
Move the mower off its charging station, switch it off and remove the security key. Wait for moving parts to stop before handling the mower.
Use a clean, dry work area. Protect the shell and vision module if the mower needs support, and wear protective gloves around the cutting blades.
