The Aichi SK200 service manual gives technicians and maintenance crews a complete reference for the SK200 aerial lift’s electrical and hydraulic systems. It includes board-level component identification for the main power box, engine control board, valve control board, relay board, and voice alarm board — complete with connector pinouts, LED function tables, and trimmer adjustment specifications. The work range control system section details the unit checker, error codes, and troubleshooting procedures for the outrigger control box, boom angle sensor, boom length sensor, and rotation sensor. Hydraulic circuit diagrams show the main control valve, outrigger control valve, jack cylinders, elevation cylinder, telescoping cylinder, and rotation motor with relief valve pre-set pressures. The inspection and adjustment chapter provides specific voltage values, resistance readings, and speed measurements for calibrating the boom angle sensor, boom length sensor, null trimmer, gain trimmer, TR trimmer, and delay trimmer, along with step-by-step procedures for verifying work radius, boom rotation limit angle, and outrigger extension indicators.

What This Manual Enables You to Do

With this Aichi SK200 service manual on hand, you can properly diagnose electrical faults in the main power box, engine control board, valve control board, and relay board using the included schematics and pinout data. You can calibrate the work range control unit, adjust the boom angle and boom length sensors to exact voltage and resistance values, and tune the actuating speeds for rotation, telescoping, and elevation to factory specifications. The manual also supports scheduled maintenance — daily and periodical inspection check sheets, withstand voltage test procedures, function tests, and service limits for natural descent of jack cylinders, elevation cylinder, and telescoping cylinder are all included. Whether you are troubleshooting an outrigger sensor fault, replacing a relay, adjusting the limited speed trimmers, or performing a full annual inspection, the SME-318A manual provides the correct procedures and specifications to complete the job accurately.

Why Correct Procedures and Specifications Matter

The Aichi SK200 is a truck mounted aerial lift with a rated load of 200 kg (440 LBS). Incorrect adjustment of the work range control system, boom angle sensor, or boom length sensor can lead to unsafe operating conditions, improper work radius limiting, or failure of the interlock and emergency stop systems. The service manual provides the exact voltage values, resistance readings, speed measurements, and relief valve pressures needed to keep the machine within its designed safety envelope. Following the manufacturer’s adjustment and inspection procedures helps ensure the aerial lift operates reliably and safely.
