Linde Series 391 H14-H20 Diesel, LPG & CNG Service Manuals

The Series 391 collection combines diesel/LPG service training for H14, H16, H18 and H20 trucks with a separate CNG training publication for H16CNG, H18CNG and H20CNG. The principal training cover is dated July 2013; the CNG volume is dated March 2010.

Fuel-specific workshop references

The CNG publication focuses on system principles, components, adjustments, tests and electrical circuits. Separate diesel, LPG and CNG diagram books keep the fuel-system references distinct. The original diesel operating cover identifies Series 391-01 H14D, H16D, H18D and H20D, while the gas operating book carries its own LPG/CNG model list.

Select the complete model designation and fuel type before using a procedure or wiring reference. CNG coverage begins with H16CNG in the identified service volume; it should not be extended to an unlisted H14CNG model. The June 2013 operating instructions are separate from the workshop training books.
