Introduction and Operation

The opening chapters identify the PDM truck by name plate and model number, explain the rating structure (PDM 20 lifts up to 2000 pounds, the PDM 25 up to 2500 pounds and the PDM 30 up to 3000 pounds at a 24-inch load center), and lay out the safety features that define the platform, including the dead-man brake, the belly-button reversing switch and the high-speed limit switch. The operation chapter walks through instruments and controls, forward and reverse travel with speed control, steering, the four possible stopping methods, parking procedure, battery charging, load handling and the correct approach to moving a disabled truck.

Planned Maintenance and Troubleshooting

Planned maintenance covers the monthly and quarterly checks in a full inspection and service chart, battery care including hydrometer testing and specific gravity targets, and lubrication with recommended grease and oil types plus hydraulic oil capacities by lift height. The troubleshooting chapter is a complete fault-finding guide organised by symptom: truck dead, travel faults, braking faults, lifting or lowering faults and miscellaneous malfunctions, each with probable causes and corrective actions.

Steering Arm, Control Head and Brake Servicing

The steering arm and control head section covers cold conditioning, belly-button switch adjustment, control head switch replacement, speed control switch return spring replacement, steering arm return spring adjustment and replacement, pivot tube replacement and electrical control cable replacement. The brake section is split by truck serial number, with separate adjustment and disc brake parts replacement procedures for serial 333761 and higher versus 333620 to 333760.

Transmission, Wheels and Elevation System

The transmission, drive wheel, caster wheel and load wheel chapter covers transmission removal and disassembly, drive wheel replacement, caster wheel assemblies 901610 and 901100, and load wheel service. The elevation system chapter handles ram head replacement for non-telescopic, telescopic and full free-lift trucks, yoke sheave replacement, lift chain adjustment and replacement, lift cylinder removal, inner mast removal, lift carriage and mast replacement, mast lubrication, adjustable straddles and base and frame items such as cabinet door latches and battery connector replacement.

Hydraulic System Servicing

Hydraulic coverage begins with relieving system pressure, then moves through line, fitting and hose replacement, filter replacement, flow control valve service, hydraulic pump and motor assembly service (016912, 016922 and 016936), control valve service and lift cylinder repair for both telescopic / non-telescopic and full free-lift configurations. Each procedure includes disassembly, inspection and reassembly steps.

Electrical Components and Optional Equipment

The electrical chapter covers the control panels, 2nd speed / 3rd speed / dynamic brake single pole contactor service, forward-reverse double pole contactor service, pump motors, drive motors, batteries, the high-speed limit switch and battery chargers including the ‘Smart’ charger 004975-01 and the 30-amp timer charger. Optional equipment covers the keyswitch, hour meter, battery capacity indicator and remote control.

Illustrated Parts Breakdown

The final chapter is the illustrated parts breakdown, with exploded views and parts lists for the control head assembly, push-button switches, cold conditioning, steering arm and pivot cap, brake and linkage, transmission, base and frame, adjustable straddles, load wheels, caster wheels, standard masts (telescopic and non-telescopic), full free-lift inner and outer masts, lift carriage, lift control valve, hydraulic installation, hydraulic panel, remote installation, lift cylinder, pump and motor assemblies, drive motor, contactor panels and battery chargers.
