Manual Section: Fault Finding (2140 Electronic Management System)Frequently Asked Questions
How do I reset the service light on a JCB Fastrac 2150?
To reset the service light, initiate the flashing 'SERVICE' message on the centre display 30 by pressing SET UP/SELECT button D. Then, use buttons A or B to adjust the displayed total running hours for the next service, which can be incremented in 50-hour steps. This procedure applies to Fastrac models with EMS Software Version 7.00 onwards.
What do error codes mean on a JCB Fastrac 2135?
Error codes on a JCB Fastrac 2135 are communicated via blink codes displayed on the Instrument Cluster's Gear Display 10, using Snail, Tortoise, and Hare icons. These codes, along with their descriptions, possible causes, and recommended actions, are detailed in tables within the 'Diagnostic Error Code Tables' section of this manual. For example, D001 indicates an EMS ROM memory error, suggesting reprogramming the EMS software.
What are the torque settings for wheel nuts on a JCB Fastrac 2125?
For a JCB Fastrac 2125, the torque settings for wheel nuts vary by axle. Rear axles with 12 nuts per wheel require a torque of 600 Nm (60.0 kgf m, 440 lbf ft), while all other axles require 500 Nm (51.0 kgf m, 370 lbf ft). It is important to check these torques every ten hours on new machines or after removal and refitting, and no oil should be applied to the threads.
how to reset JCB Fastrac 3155 fault codes
To reset JCB Fastrac 3155 fault codes, access the Psion Workabout's 'Download Data Log Menu Options' and select 'Erase Datalog Memory'. The Psion will display the percentage of memory used; if high (e.g., 50% or more), press Enter to start the erase process, or On/Esc to return to the Main Menu. Once erased, data logs cannot be restored.
What are the replacement specifications for hydraulic filters?
When replacing hydraulic filter elements, for wet clutch machines, fit a new paper insert into the metal outer element J. For all machines, assemble the new or refurbished element onto the spindle using a new seal L and ensure the top lip of the seal locates in the groove inside the filter head M. The element assembly F should be fitted with a new 'O' ring G, and nuts C tightened to 7 Nm (5 lbf ft).
