Verify the fuse ratings in the distribution box. Check page 272 to confirm the revolver ignition fuse F13 is correctly sized at 5A. Always replace fuses with ones of the correct ampere rating according to page 239. Inspect the drive pilot solenoid circuit wiring for chafing or shorts.
Manual Section: Electrical System Checks (Operation, Condition, Battery, Fuses, Relays)Red engine oil pressure low warning symbol illuminates on the display screen during heavy digging operations. p. 75
Stop the machine immediately and lower the attachments. Check page 75 to confirm the red engine oil pressure warning symbol meaning. Inspect the engine oil dipstick and ensure the fluid level is correct for the 20.4L system capacity. Look for excessive smoke or unusual smells around the block.
Manual Section: Engine Checks (Condition, Leaks, Level)Machine feels unstable or judders while roading between jobsites at maximum travel speed. p. 278
Inspect all tires for severe cuts, bulges, or embedded objects. Measure the tire pressure and adjust to 6.5 bar for 10.0x20 14PR tires as specified on page 278. Torque all M24 wheel nuts to exactly 500 N.m to prevent wheel wobble during travel.
Manual Section: Tyre Condition and InflationFrequently Asked Questions
How do I reset the JCB JS145W/JS160W hydraulic pressure warning?
To reset the hydraulic pressure warning, you must decrease the machine lift when the overload protection system buzzer sounds and the icon appears. Once the lift is lowered to a safe position, the buzzer and icon will be cancelled, and the system will reset automatically. This is detailed in the 'Overload Warning System' section.
How do I perform a throttle or joystick calibration on a JCB JS145W/JS160W?
To perform a throttle calibration, start the engine, navigate to the machine set-up menu, and use the rotary control to select the Throttle Calibrate icon. Press the rotary control to begin calibration, which will display RPM and Throttle %; a tick will appear when complete. The manual does not provide instructions for joystick calibration.
