Manual Section: Routine MaintenanceFrequently Asked Questions
How do I reset the control mode on a JCB 8080 excavator?
The manual describes how to select control patterns (ISO or SAE) using a switch located behind the driver's seat. To change the control mode, remove the fuse box cover, access switch C, and the selected pattern will be indicated on a flashing display on the right console D. The manual does not use the term 'reset' for control modes, but rather 'select'.
How do I reset a fault code on a JCB 8080?
To address warnings displayed on the EMS panel, press the ACK button. This action will acknowledge the warning message and silence the buzzer, but it will not extinguish the warning lamps or clear the underlying fault. For persistent errors, the manual advises contacting your JCB dealer.
How do I reset the monitor/display on a JCB 8080?
You can reset specific display values on the EMS monitor. For example, the total hours that the high flow or double acting high flow features are in use (up to 99, 999 max) can be reset to zero by pressing the ACK button in the Set Mode menu. The SET button allows access to the Set Up menu, where various parameters can be adjusted.
How do I reset servo relief pressure on a JCB 8080 ZTS?
The manual indicates that adjusting relief valve pressure is a specialist job. For issues such as 'Main relief valve pressure set too low' or 'Low pressure setting for the relief valve', the remedy is to '*Adjust pressure', with the asterisk denoting that this task should be done by a specialist. No operator-level procedure is provided for resetting servo relief pressure.
What are the replacement specifications for Rubber tracks?
Rubber tracks should be visually inspected and replaced if one or more metal cores are missing, steel cord is exposed, more than half of the track is missing, or the track comes off even when fully tensioned. The machine is available with 450mm (18'') rubber tracks.
