JCB 506C, 506CHL, 508C Common Problems This Manual Covers
JCB 506C boom drifts down when holding position or hydraulic system slips during lifting cycle p. 135
Check the hydraulic fluid level (page 135) and inspect the hose burst protection valves (page 145) for proper function. Ensure the hydraulic tank capacity for the 506C (32 gal / 121 L) is met (page 101).
Manual Section: OperationEngine temperature gauge spikes and overheating warning light flashes during heavy load operation p. 102
Inspect the radiator core and clean out any debris blocking airflow (page 103). Verify the engine coolant mixture matches the 50% concentration spec (page 102). Drain and flush the system if contaminated, refilling with exactly 6.2 gal (23.5 L) of fresh coolant (page 101).
Manual Section: Fluids, Lubricants and CapacitiesMachine bounces excessively during transport or steering feels sluggish on hard surfaces p. 165
Verify all tires are properly inflated before operating the handler. Adjust the tire pressure to exactly 58 lbf/in² (4.0 bar) as detailed on page 165. Inspect the front and rear wheel nuts, ensuring they are tightened to 680 Nm (500 lbf ft) (page 150).
Manual Section: GreasingTransmission warning indicator illuminates on dashboard and machine hesitates during forward travel p. 51
Review the troubleshooting procedures for transmission warning indicators (page 51). Park the machine on level ground and check the transmission fluid dipstick (page 139). If the fluid level is low, add approved oil until reaching the full mark, keeping the total 4.8 gal (18.25 L) capacity in mind (page 101).
Manual Section: OperationFrequently Asked Questions
JCB 506CHL error code meaning
The manual lists several warning lights that indicate specific issues. For example, the 'Engine Coolant Temperature High' light (2) illuminates if the engine coolant temperature rises too far. The 'Transmission Oil Temperature High' light (13) indicates if the transmission oil temperature rises too far. The 'Water in Fuel Indicator' light (16) signals the presence of water in the fuel system, requiring the water separator and engine filter to be drained.
JCB 506C engine fault code list
The manual provides a list of engine-related warning lights that indicate faults. These include 'No Charge' (1) for battery charging circuit failure, 'Engine Coolant Temperature High' (2) for excessive coolant temperature, 'Engine Oil Pressure Low' (3) for low oil pressure, 'Air Filter Blocked' (4) for a clogged air filter, 'Cold Start' (5) for cold weather starting, and 'Water in Fuel Indicator' (16) for water in the fuel system.
JCB 506CHL transmission fault codes
The manual lists specific warning lights related to the transmission system. These include the 'Transmission Oil Temperature High' light (13), which illuminates if the transmission oil temperature rises too far, and the 'Transmission Oil Pressure Low' light (14), which operates if the transmission oil pressure drops too far. For the latter, the light should go out when the engine is started.
How to reset JCB 508C warning light
The manual does not provide a general 'reset' procedure for warning lights. Instead, it indicates that the lights will go out once the underlying issue is resolved. For example, if the 'Low Level Coolant Indicator' (15) lights up, the instruction is to top up the coolant level as soon as it is safe to do so, implying the light will then extinguish.
