Four telehandlers, one OEM manual (#9811/5967): the 506-36, 507-42, 509-42, and 510-56, documented from first startup through long-term storage. Operation covers boom and carriage controls, stabilizer operation, load charts, and the RAS rear axle stabilization system. Routine maintenance is organized by service interval so the right job lands on the right machine. The schedule leaves nothing vague: air cleaner outer element at 500 hours, inner element at 1000, hydraulic oil filter at 500, and the fuel filter strap retaining screw torqued to 24 Nm (17.7 lbf ft). Specifications close the book with static dimensions, lift performance tables, and per-model tire pressures. Every section is bookmarked, so it opens fast on a phone in the field or a laptop at the desk.

JCB 506-36, 507-42, 509-42, 510-56 Common Problems This Manual Covers
Warning lamp illuminates on the JCB 510-56 or other Loadall dashboard at startup or during operation p. 53
Check what the instrument panel indicator means and match the specific lamp to the fault display with the cab information button. Before assuming an electrical fault, verify engine oil, the 20-liter coolant system, and hydraulic tank levels. If the coolant temperature gauge hits the red zone with an audible alarm and the Malfunction Indicator Lamp lit, shut down at once per page 53.
Manual Section: OperationEngine cranks slowly or will not start, battery or charging system lamp on p. 153
Inspect the battery terminals for corrosion and make sure the connections are tight. Electrolyte should sit 6 mm (1/4 in) above the plates, per page 153. For a discharged battery, follow the jump-start procedure with correct cable routing: positive to positive, negative to chassis ground only. Damaged, chafed, or corroded wiring connectors are also worth checking via the electrical circuit check procedure.
Manual Section: Routine MaintenancePark brake warning illuminated or machine creeps when brake is applied p. 150
Run the park brake hold test at roughly 1500 RPM as described on page 150. Should the machine move, stop work at once and report it for service. The schedule on page 114 calls for a check and adjustment every 50 hours, so confirm the brake is not overdue. Keep the machine parked until it holds correctly on the slope test.
Manual Section: Routine MaintenanceWater-in-fuel warning lamp on or engine stumbles and stalls after refueling p. 110
Drain the water separator right away: find the bowl at the base of the fuel filter assembly and drain until clean fuel runs. Renew the water separator element every 500 hours per page 110. On refitting the fuel filter, torque the strap retaining screw to 24 Nm (17.7 lbf ft) per page 173. If air has entered the system, bleed the fuel lines before attempting a restart.
Manual Section: Routine MaintenanceBoom and hydraulic functions feel slow, weak, or jerky under load p. 111
Confirm the hydraulic tank level first: the system holds 128 liters, and a low level is the most common cause of sluggish response. Pull a sample and inspect it as shown on page 177; cloudy fluid points to water or air contamination and means a filter and fluid change before further use. Make sure the hydraulic oil filter is inside its 500-hour interval on page 111. Where a pilot filter is fitted, renew it at 500 hours and torque the cap to 25 Nm per page 179.
Manual Section: Routine MaintenanceTransmission warning lamp on or harsh shifting when machine is hot p. 115
Stop and let the machine cool with the engine at low idle. Measure the transmission oil against the 19-liter gearbox capacity listed on page 115. The transmission oil filter is due every 500 hours per page 110; on refitting, turn it 3/4 of a turn past contact and torque the strainer bolts to 10 Nm (7 lbf ft) per page 183. If the fault stays after cooling and a correct oil level, send it for workshop diagnosis.
Manual Section: Routine MaintenanceFrequently Asked Questions
How do I reset the warning lights on a JCB 506-36 telehandler?
If a warning light comes on and the alarm sounds, the only way to silence it is to set the starter to 'off'. For a warning fault (SERVICE), press the Information switch for 3 seconds to acknowledge the error, then press it again to scroll through existing fault codes.
How do I clear fault codes on a JCB 507-42?
On the 507-42, system faults show as messages on the LCD. Press the Information switch for 3 seconds to acknowledge a SERVICE error, then press it again to scroll through any existing fault codes.
How do I reset the service indicator on a JCB 509-42?
A service indicator shows as a Warning Fault (SERVICE); press the Information switch for 3 seconds to acknowledge it. Should a new warning occur, or an existing one clear and return, the SERVICE message appears again.
How do I reset the transmission fault on a JCB 510-56?
Any fault that triggers a warning light and alarm can only be silenced by setting the starter to 'off'. A Warning Fault (SERVICE) signals impaired machine function; press the Information switch for 3 seconds to acknowledge it.
How do I check active faults on a JCB telehandler cab display?
Active faults appear as messages on the LCD; press the information button to scroll through the existing codes. A Critical fault (STOP NOW) means immediate damage risk and cannot be acknowledged, whereas a Warning Fault (SERVICE) clears with a 3-second press of the Information switch.
