The Hyster A370 Series Repair Service Manual is the official workshop technical document for the UT13-20PTE electric three-wheel and four-wheel counterbalance trucks. Designed as part of Hyster’s Utility (UT) range, these machines prioritize straightforward maintenance and high-efficiency AC power delivery. This manual provides the detailed electrical and mechanical roadmap required to service the A370 platform, which utilizes a specialized 48-volt architecture for optimized indoor performance. By utilizing this 908+ page factory manual, service engineers can perform precise calibrations on the motor controllers and VSM (Vehicle System Manager) to maintain the smooth acceleration and regenerative braking features characteristic of the UT series.

Covering the 1.3 to 2.0-tonne capacity class, the A370 series is engineered for agility in narrow aisles and distribution centers. A key focal point of this manual is the configuration difference between the compact UT13PTE and the high-capacity UT20PTE models. Each model requires specific attention to its counterweight mounting and steering axle pivot tolerances. This documentation provides the exact clearance, torque, and pressure specifications designated by Hyster for the A370 series, ensuring that every repair from a simple fuse replacement to a full drive motor overhaul is performed to factory standards.
