This Linde Series 392 service training manual gives technicians and workshop professionals a complete picture of the H20 and H25 forklift platforms in both diesel and LPG configurations. The document walks through the electronic diesel control system used on the VW BEQ engine, including sensor operation, injection timing, fuel quantity regulation and the self-diagnosis routines that keep these trucks running efficiently. For LPG trucks, the VW BEF engine section explains the electronic ignition system, vaporiser operation, mixer function and LPG shut-off valve in practical detail.

On the transmission side, the manual covers the Linde Truck Control (LTC) system, the HPV 55-02 variable-displacement pump and the brake valves used in the hydrostatic drive. Hydraulic circuit diagrams, functional descriptions of the control valve and step-by-step troubleshooting flowcharts make this a working reference rather than a theoretical overview. The mast section addresses chain adjustment, roller clearance settings for Type 185 and Type 183/186 masts, lift cylinder sealing, tilt cylinder removal and the tilt angle sensor teaching procedure.

Electrical coverage includes basic circuit diagrams for both diesel and LPG models, the central electrical system, relay and fuse layouts, and the composite instrument with its indicator functions and error code indications. The self-diagnosis chapter provides error tables, measuring value block evaluations and component checking procedures that help pinpoint faults quickly.

What This Manual Enables You to Do

With this Linde H20 H25D T Series 392 service training manual, you can perform engine diagnostics and repairs on the VW BEQ diesel and VW BEF LPG engines, including injection pump removal and installation, toothed belt replacement and dynamic injection start adjustment. You can service the hydrostatic transmission, adjust the HPV 55-02 variable-displacement pump, diagnose brake valve issues and work through hydraulic troubleshooting procedures with confidence.

The mast and cylinder service sections support chain adjustment, roller clearance setting, lift and tilt cylinder sealing, and hose reel maintenance. Electrical diagnostics are backed by circuit diagrams, component checking procedures and error code tables so you can trace faults through the LTC system and engine control unit.

Having the correct procedures and specifications matters because these trucks depend on precise hydraulic and electronic calibration to operate safely and efficiently. Whether you are a workshop technician, fleet maintenance engineer or an owner-operator who prefers to handle repairs in-house, this manual gives you the reference material needed to do the job correctly.
