JCB 506-36, 507-42, 509-42, 510-56 Common Problems This Manual Covers
Will not crank or charge warning appears
The machine may fail to crank or start intermittently, sometimes with a battery or charging warning lamp. A battery, charging system, or wiring fault in the starter circuit is the usual cause, covered by the electrical checks in this section.
Manual Section: Routine Maintenance p. 103Overheat alarm or power derate
An overheat alarm, derate, or loss of power under load points to low coolant, a blocked radiator, or a fan and thermostat issue. The Routine Maintenance section covers coolant and hose checks, with a 20 litre coolant capacity.
Manual Section: Routine Maintenance p. 103Transmission warning or harsh shifting
Harsh shifting or the machine dropping drive when hot can come from low or contaminated transmission oil or a pressure fault. The Routine Maintenance section covers the transmission oil filter service at its 500 hour interval.
Manual Section: Routine Maintenance p. 103Weak or jerky boom hydraulics
Boom and telehandler functions turn weak, jerky, or slow with low hydraulic oil, clogged filters, or air ingestion. The Routine Maintenance section covers the hydraulic oil filter at a 500 hour interval and the pilot filter cap at 25 Nm.
Manual Section: Routine Maintenance p. 103Water-in-fuel warning after refueling
A water-in-fuel warning or stalling after refueling points to contaminated fuel or an undrained water separator. The Routine Maintenance section covers the fuel filter and water separator element at their 500 hour intervals.
Manual Section: Routine Maintenance p. 103Park brake creeps on hold test
A park brake warning or the machine creeping during the hold test signals brake wear or an adjustment issue. The Routine Maintenance section covers the park brake check interval and the test carried out at about 1500 RPM.
Manual Section: Routine Maintenance p. 103Attachment hoses will not couple
Fitting an attachment means connecting the hydraulic hoses through the quick release couplings correctly. The Optional Attachments section explains the couplings and how to connect and disconnect hoses.
