Description

BT SWE100, SWE120 and SWE120S Support Arm Truck Service Manual

This BT SWE100 / SWE120 / SWE120S support arm truck service manual is the full workshop reference for BT’s battery-powered stacker range, valid from serial number 715612- and issued under order number 220813-040. It walks a technician through every major assembly on these trucks: the electric drive motor, the two-stage angle drive gear, the spring-loaded electromagnetic brake, the tiller arm steering head, the hydraulic lift and lowering circuit, the mast and lift chain system, the 24 V electrical system and the Curtis 1243 transistor regulator. Whether you are servicing a single SWE100 in a warehouse or running a fleet of SWE120 and SWE120S units, this manual provides the procedures, torque values, clearances, wiring diagrams and diagnostic fault codes needed to keep the trucks running safely.

General Product Information and Technical Data

Opens with the truck’s intended application, prohibited uses, and full daily-use data tables for the SWE100 and SWE120. You get rated capacities (1000 kg and 1200 kg), lift heights, travel speeds, gradient climbing ability, weights with and without battery, turning radius and permitted drive wheel materials. Dimensional drawings and identification, capacity and modification plate layouts are included so you can match a truck to its correct specification before any work begins.

Maintenance, Lubrication and Tools

The preventive maintenance chapter provides a full hour-based maintenance schedule covering intervals at 5, 20, 80, 500, 1000 and 3000 hours, with specific jobs for each interval. A separate lubrication schedule maps grease and oil points on the truck. The oil and grease specification chapter lists recommended lubricants by ambient temperature and application area, including hydraulic oil, transmission oil, chain grease and steering bearing grease. The tools chapter covers the special connectors and service instruments required for working on these trucks, including Super Seal, AMP and Molex connector tools and the CAN service interface.

Support Arm Chassis and Drive Motor

Support arm chassis coverage applies to the SWE120S and includes the main components, adjustment of support arm width from 900 mm to 1300 mm, and exchange procedures with torque settings for the clamp bolts. The electric drive motor chapter gives component breakdowns, dismantling from the truck, bearing shield and rotor removal, carbon brush inspection, cleaning methods and insulation resistance testing, plus technical data such as minimum carbon brush length, minimum commutator diameter and winding resistance.

Drive Unit, Gear and Brake

The drive unit/gear chapter covers the two-stage angle transmission with a 19.14:1 ratio, oil volume and type, top cover leakage repair, and drive shaft sealing ring replacement including bearing and shim handling. The electromagnetic brake chapter covers the brake disc exchange procedure with wear limits, minimum disc thickness and nominal play values. These two chapters are essential for keeping the drive and stopping systems safe and reliable.

Steering and Tiller Arm

The steering chapter breaks down the tiller arm assembly, adjustment of the brake microswitch, and step-by-step procedures for changing the signal button/switch, lift/lowering button and pushbutton. Component diagrams identify every part number and spring in the handle assembly, which is where most operator controls and the truck’s display are located.

Electrical Systems, Fault Codes and Parameters

This is the largest section. It includes the electrical parts layout, a complete list of symbols, and five separate wiring diagrams covering the transistor regulator, tiller arm, keypad and Curtis controller. The functional description explains starting, driving, neutral speed reduction, braking, lifting, lowering and horn operation. Fault codes are listed with possible causes and actions for both caution (C) and error (E) codes. Parameter tables cover operator parameters and service parameters including PIN codes, battery size selection, hour meter configuration, service interval, lift button selection and login method. The transistor panel and Curtis 1243 technical specifications are included with operating voltages, current limits and temperature thresholds.

Hydraulics, Lift Chains and Battery Charger

The hydraulic system chapter gives the full hydraulic diagram and component description for lift, lowering, operating pressure, relief valve and pressure switch, with specific pressure values for each model. The main lift chain system chapter covers chain setting, inspection for noise, rust, stiff links, bolt rotation, outline wear and stretching, cleaning and lubrication with viscosity-class recommendations. The built-in battery charger chapter covers charging behaviour, troubleshooting and charging settings tables for both freely ventilated and valve-regulated batteries.

Control and Computer Equipment (TruckCom)

The final chapter covers the TruckCom 3.5 communication software, the CAN interface, connection and disconnection procedures, program downloading (normal and emergency), truck report generation, parameter functions and diagnostics. It explains the tiller arm, drive controller, pump controller and EPS steering servo diagnostic tabs, plus installation instructions for Windows 95/98, XP/2000 and NT.

Why This BT Support Arm Truck Service Manual Matters

These trucks are compact, high-duty electric stackers used in warehouses, cold stores and production lines. When something goes wrong — a brake that will not release, a drive motor drawing excess current, a hydraulic leak from a top cover, or an error code on the display — guessing is expensive. This manual gives you the exact diagnostic path: the fault code list tells you what each C and E code means, the wiring diagrams tell you which pins to probe, and the technical data tables give you the resistance, voltage and torque values to compare against. For planned maintenance, the 500-hour service schedule and lubrication chart remove the guesswork from routine servicing. For overhauls, the exploded component drawings and tightening torques (26.6 Nm for gear housing bolts, 120 Nm for support arm clamps, 300 Nm for the drive shaft nut) mean you can reassemble to factory specification.
