PDF Manual Specifications

Important Compatibility Note: F878, E878 and Other Series

Published listings identify the GP/GLP/GDP135VX and 155VX model family under F878 and E878, while earlier related publications use other series references. The editions may differ in engine revisions, transmission sections, diagnostic information and serial-number coverage.

Before purchasing, compare the series and serial number on the forklift with the manual's stated coverage. Check whether your machine has a GM or PSI gasoline/LPG engine, a Kubota diesel engine, and which transmission and mast are installed. Similar model names alone do not establish that two manuals are interchangeable.
