Section 1 – General

The General section opens with essential safety information, including safety alert symbols and signal words used throughout the manual. It covers operator qualifications, operator conduct, handling loads, attaching loads, lifting and moving loads, holding loads, multiple load line operation, signals, and operational aids. The section also includes detailed procedures for pedestal-mounted and barge-mounted cranes, personnel handling policy, getting on and off the crane, crane access points, operating near electric power lines and transmission lines, refueling, fire extinguishers, and accident reporting. Warning and information signs are covered, along with nameplates and decals, English and metric conversions, outline dimensions, and weights. This section establishes the safe operating envelope for the 4600 S4 and is required reading before any maintenance or repair work begins.

Section 2 – Attachment

The Attachment section provides complete rigging and assembly information for the boom and jib systems. It begins with boom disassembly safety considerations and then covers boom assembly procedures, the universal anchor joint, and the #27B boom rigging assembly. Detailed instructions are provided for the boom angle indicator, gantry assembly, gantry lifting and radiator fan hydraulic systems, equalizer assembly, automatic boom stop, and telescopic air cushioned boom stop. The section also includes the #125 jib assembly and jib backstay assembly. Rigging drawings are referenced throughout, showing pendant arrangements, spreader bars, pendant rubbing frames, boom point assemblies, and jib attachment points. This section is indispensable for anyone assembling, disassembling, or inspecting the lattice boom and jib on the 4600 S4.

Section 3 – Maintenance

This is the largest and most technically detailed section of the manual, covering preventive maintenance and repair procedures for the entire crane. It includes preventive maintenance checklists with hourly intervals (daily, weekly, monthly, quarterly, and semi-annual), air system pressure settings, and a comprehensive set of schematics covering travel control, independent swing, boom hoist control, backhitch pin control, drum rotation indicator, front and rear drum control, boom hoist wire rope spooling indicator, travel brake control, drum pawls, engine throttle, boom hoist auxiliary brake, travel lock controls, swing lock, steering control, and pawl on boom hoist. Air piping schematics for the air supply, wiper control, swing brake, air horn, and full range VICON power load are included. The section also contains wiring identification for the electrical system, electrical schematics, drum control valve adjustment, pressure switch adjustment, pressure regulating valve maintenance, air system filters, solenoid valves, hydraulic test gauges, hydraulic system maintenance, hydraulic fluid conditioners, boom hoist maintenance, worm gear and worm shaft inspection, drum brake maintenance, drum clutch maintenance, engine cooling systems, radiator cooling and shutter control, engine air cleaners, battery maintenance, torque converters, VICON controlled converters, transmission case lubrication, oil filters, rotating bed sump circulating oil system, boom/jib/tower and mast inspection and repair, wire rope installation and maintenance, and load block and hook-and-weight ball maintenance. This section alone makes the manual an essential shop reference.

Section 4 – Lubrication

The Lubrication section contains the 4600 S-4/5 Lubrication Guide, lubricant specifications, and approved lubricants for arctic operation. It specifies the correct greases, gear oils, transmission and chain case oils, controlled torque converter oil, and hydraulic oils for the machine, along with ambient temperature ranges for each ISO grade. This section ensures proper lubrication intervals and fluid selection for reliable operation in varying climates.

Section 5 – Capacities

The Capacities section refers to the separate capacity chart manual provided with the crane or to the laminated capacity charts retained in the operator’s cab. It also includes load block data. This section directs the operator to the correct lifting capacities, wire rope specifications, drum and lagging information, and other capacity-related data for safe lifting operations.

Section 6 – Operating Controls

The Operating Controls section covers standard hand signals for controlling crane operations, converter operation for controlled and non-controlled converters, the 4600 Series-4/5 Operator’s Guide, and preparation for cold weather. It explains how to operate the crane’s controls safely and efficiently, including cold-weather starting aids, cooling system preparation, battery care, engine oil and fuel recommendations, gear oil and hydraulic oil selection for cold climates, and air system maintenance in freezing conditions.

Section 7 – Adjustments

The Adjustments section provides step-by-step procedures for adjusting the hook roller, pilot house positioner, hydraulic boom hoist system, boom hoist brakes, boom hoist ratchet and pawl, boom hoist wire rope spooling indicator, swing brake, drum clutch, drum brakes, treadle valve, VICON power load lowering (reversing) assist, main drive shaft, main drive shaft clutch, air-applied travel brake, hydraulic travel system, air throttle actuator, transmission case chain tighteners, crawler adjustment, hydraulic hand pump, and steering control. Each procedure includes specifications, dimensions, and adjustment values to ensure proper operation and safe performance.

Section 8 – Troubleshooting

The Troubleshooting section contains the Straight Air Troubleshooting Chart, which helps diagnose and remedy common air system problems. It covers complaints such as brake or clutch release too slow, slow brake application, clutch or brake slipping or not holding, clutch or brake overheating, control valve leaking at the exhaust port, system building pressure slowly, pressure dropping rapidly with engine stopped, and compressor building pressure beyond gauge maximum. Probable causes and remedies are provided for each symptom, making this section a practical field diagnostic tool.
