Komatsu's own publication number, WEAMWB9500, marks this 112-page Komatsu WB95R-1, WB97R-1 operator manual PDF as the factory book for both backhoe-loaders, not a reseller's rewrite. Lifting capacity charts cover each machine with the standard boom and with the transportable device, so you know before the pick whether the load stays inside the numbers. Instrumentation pages identify every warning light, gauge, and push-button on the dash, while the maintenance chapter takes up roughly a quarter of the book with fluid and coolant specs, grease points, and service intervals from the daily walkaround to long-term storage. When charging trouble shows up, check output at the 55A alternator before you condemn the 155 Ah battery. Two work ends, two control sets, zero room for guesswork. Bookmarks and a live text layer put the fuse chart or a fill capacity two clicks from the cover.

Komatsu WB95R-1, WB97R-1 Common Problems This Manual Covers
Komatsu WB97R-1 gear pressure sensor alarm on dashboard, transmission slips or loses forward drive
Check the transmission oil level with the machine parked on level ground; low oil starves the gear clutch circuits. Work through the converter faults in the fault identification section on pages 101-107: low clutch pressure, low pump flow, lack of power. Confirm the hydraulic oil filter is within its 250 hour interval, then have your dealer read the alarm codes.
Manual Section: Fault Identification p. 101Engine cranks slowly or will not start on cold mornings, dashboard lights dim
Test the battery charge first; the standard battery is 155 Ah, 12 volt, and slow cranking usually means it is low. Clean and tighten the terminal clamps, then follow the flat battery and auxiliary cable start procedure in the fault identification section on pages 101-107. Charge the battery fully before retrying; repeated jump starts shorten its life.
Manual Section: Fault Identification p. 101Engine temperature gauge climbing and hydraulic oil running hot during heavy summer digging
Clean the radiator and oil cooler cores with compressed air from the fan side; one cooling pack cools engine, hydraulic, and transmission oil, so a plugged core heats all three. Follow the hot weather precautions on page 59 for coolant, radiator cap, and lubricant checks, and keep engine oil fresh with changes every 250 hours.
Manual Section: Precautions to Be Taken During Hot Weather p. 59Machine feels underpowered, engine bogs down when loader and backhoe hydraulics work hard
Check the fuel system before blaming the hydraulics: drain water from the filter, replace it if past the 500 hour interval on page 71, and bleed air from the supply circuit. Then compare symptoms against the hydraulic circuit faults, pump noise and slow movement, in the fault identification section on pages 101-107.
Manual Section: Maintenance p. 71Battery warning light stays on while engine runs, headlights dim at idle
Verify the alternator belt tension and condition first; a loose belt drops output from the 55 A alternator and the light stays on. Check the charging circuit fuses and relays on the side dashboard panel shown on page 48. If the light remains lit at working RPM, test alternator output before replacing the battery.
Manual Section: Fuses and Relay p. 48Frequently Asked Questions
What is the correct engine oil change interval for the Komatsu WB95R-1?
The engine oil should be changed every 250 hours. For the first 50 hours, a specific maintenance procedure is required as outlined on page 76. p. 77
What is the correct tightening torque for a 10mm 8.8 grade bolt on the Komatsu WB95R-1, WB97R-1?
The standard tightening torque for a 10mm diameter bolt of 8.8 grade is 4.6 kgm (45 Nm). p. 75
How do I adjust the fan-belt tension on the WB95R-1?
The fan-belt tension is adjusted by pressing the belt with a force of 44 N (4.5 kg), which should result in a deflection of about 10 mm. If the deflection is greater, loosen the alternator mounting screws and move the alternator to achieve the correct tension. p. 84
What is the capacity of the hydraulic oil tank for the WB95R-1?
The hydraulic oil tank has a capacity of 132 liters for the first filling and 75 liters for an oil change. p. 72
What is the procedure for bleeding air from the braking circuit?
To bleed the braking circuit, press one brake pedal fully down and hold it while loosening the corresponding drainage cap (3) until the pedal can go no further. Tighten the cap, release the pedal, and repeat until oil runs out without air bubbles. p. 92
