Part of the JCB Operator Manuals.
A quickhitch that won't lock, an overload alarm nobody can explain, a machine strapped wrong on the trailer: this 220-page JCB 100 C-1, 90 Z-1 operator manual PDF (OEM ID 9831/1000) answers those calls for both compact excavators. Load charts and the overload warning system sit beside the arm, dozer blade and auxiliary control layouts, and the Operation chapter fills roughly a third of the book, running from walk-around inspection to slope work, trailer loading and recovering a disabled machine. Maintenance schedules set out intervals and pre-start checks for the slew ring bearings, pivot pins, tracks, fuel water separator and cooling pack. Fill the hydraulic system to 118 L, and check any rockbreaker you fit against the 190 bar (2,753.6 psi) auxiliary circuit pressure. One missing fill figure can park a whole crew. Chapter bookmarks and a live text layer take you straight from the cover to the fuse and relay tables or the load charts in seconds.

JCB 100 C-1, 90 Z-1 Common Problems This Manual Covers
JCB 100 C-1 or 90 Z-1 compact excavator engine cranks on the starter but fails to start
Verify the starter motor has had time to cool between cranking attempts; holding the key over a dead engine only cooks it. Prime the engine lubrication system as the starting procedure directs, then try again. If it still won't fire, bleed air out of the fuel system and check the sediment bowl for water.
Manual Section: Engine Starting TroubleshootingAfter an incorrect PIN entry the immobiliser system locks and the engine will not start
Verify the correct PIN with the machine owner before keying anything else in; a wrong entry is what locks the system. Follow the immobiliser troubleshooting steps to clear the lock. If keys need programming, locate the master key first, since key programming runs through it.
Manual Section: Immobiliser TroubleshootingWater and sediment collecting in the fuel sediment bowl with air trapped in the fuel system
Drain the water and sediment out of the sediment bowl and look hard at what comes out before you call it done. Bleed the fuel system following the bleeding procedure until the air is purged. Refuel from a clean source; the tank holds 112L, listed on page 202, so contaminated fuel adds up fast.
Manual Section: Fuel System TroubleshootingHydraulic services not operating correctly, with contaminated fluid in the tank and damaged hoses
Inspect each hydraulic hose for damage along its full run and replace any that are damaged before the machine works again. Check the oil in the hydraulic tank for contamination; the tank holds 66L and the full system 118L, per page 202. Release accumulator pressure before loosening any hydraulic connection.
Manual Section: Hydraulic System TroubleshootingElectrical functions cutting in and out with corroded battery terminals and loose connections
Clean corrosion off the battery terminals and check each clamp is tight. Inspect the wiring harness along its runs for chafing, and check every connector for damage and corrosion. Verify each connection is fully seated; a loose plug on a machine that shakes all day will drop out intermittently.
Manual Section: Electrical System TroubleshootingTrack tension set incorrectly, with visible damage to the track and oil leaking
Check track tension and adjust it following the track tension procedure before the machine travels again. Inspect the full length of each track for damage while you are down at it. Clean off the undercarriage and trace any oil leak to its source, then report leaks for repair rather than running on them.
Manual Section: Track Tension TroubleshootingFrequently Asked Questions
What are the replacement specifications for the fuel filter and water separator element on the JCB 100 C-1, 90 Z-1?
To replace the fuel filter, you must drain and remove the water separator bowl by releasing the locking ring, then unscrew and remove the filter element. Fit a new element, refit the water separator bowl, and secure it with the locking ring. Finally, bleed the fuel system as described on page 159. p. 172
What are the engine oil filter replacement specs for the JCB 100 C-1, 90 Z-1?
To replace the engine oil filter, remove the cap from the oil filter housing, remove and discard the old cartridge, and fit a new filter with new gaskets. Tighten the cover to the correct torque value as specified in the Technical Data section on page 193. p. 168
What is the correct torque value for the FOPS bolts on the JCB 100 C-1, 90 Z-1?
The correct torque value for the FOPS (Falling Object Protective Structure) bolts is 74 N·m. p. 205
What is the capacity of the fuel tank for the JCB 100C-1 and 90Z-1?
The fuel tank capacity for these machines is 112 liters. p. 202
How often should the engine oil be replaced?
The engine oil should be replaced every 500 hours of operation. p. 151
