Covering all four capacity variants in Utilev's UT20P to UT35P forklift range, this 110-page Utilev UT30P service manual PDF (OEM ID 76007600) fits your truck whichever gasoline or diesel engine sits behind the counterweight. Hydraulic schematics route the main oil circuit from pump through spool valve, main relief and tilt auto-lock valves to the lift and tilt cylinders, while electrical schematics trace the OPS and park brake alarm wiring. Torque converter, inching valve, king pins, wheel brakes and mast each get teardown or adjustment procedures, plus troubleshooting for steering, brakes, hydraulics and electrics. Change the engine oil filter every 600 hours or 3 months, and refill a Nissan K25 UT30P with 3.5 liters (3.7 qt). Setting a wheel brake clearance regulator from memory rarely ends well. Print the brake and hydraulic chapters, let them soak up grease on your bench, and keep the bookmarked, searchable file clean on the laptop.
