JCB 190 190HF 1100 1100HF Robot Service Manual VEHICLE/EQUIPMENT INTRODUCTION: The JCB 190 and 1100 series Robots are compact tracked telescopic handlers designed for work in confined spaces where traditional telehandlers and forklifts cannot operate. The Robot 190 features a compact footprint with full 360-degree slew capability, a telescopic boom capable of extending to significant reach heights, and a versatile front attachment system supporting forks, buckets, and specialized tooling. The 1100 variant offers increased lift capacity and outreach for heavier materials handling. These machines are commonly used in construction, agriculture, warehousing, and industrial maintenance applications. The HF high-flow designation indicates models equipped with auxiliary hydraulic capabilities for powered attachments. The JCB Robot uses a robust diesel engine coupled to a hydrostatic transmission providing infinitely variable travel speeds and precise boom control. Serial numbers 190 and 1100 in the range 1291500 to 1294999.
