Manual Section: MaintenanceFrequently Asked Questions
Why won’t my JCB 436ZX move?
Your JCB 436ZX may not move if the parking brake is engaged, as it electrically disconnects the transmission drive. Additionally, if the transmission is not in neutral, the display panel will show "IN GEAR" and an audible buzzer will sound, or if the parking brake is on and the transmission is not in neutral, "PARK BRAKE" will be displayed, preventing movement. To override a start inhibit, you can push the MANUAL button once.
