Mechanical Systems
Mechanical part details the front head back head accumulator disassembly. Torque specs for tie rods listed around 500-600 Nm but check for exact on critical bolts not all fasteners covered. Chisel replacement steps how to remove install with molybdenum grease to prevent galling. Self-cleaning mechanism for dust seals kicks in during operation.
Hydraulic Sections
Hydraulic system is high pressure type with flow rates 50-80 L/min for F6 up to 200-300 L/min for F70. Procedures for connecting hoses checking oil levels bleeding lines. Troubleshooting for weak impact or no strike includes pressure settings main 180 bar back 30 bar or so depending model.
Electrical Components
Electrical chapter if applicable has wiring for auto-stop sensors resistance values. Battery 24V troubleshooting for no signal weak charge. Appendices got spec charts lubrication points periodic maintenance schedules like chisel wear every 100 hours chain tension if chain drive.
Includes diagrams for hydraulic circuits mechanical assemblies. Torque charts for accumulator but not every bolt some general guidelines. Good for field use though some sections assume you got special tools like torque multiplier.
Troubleshooting and Specs
Troubleshooting section covers common issues like overheating leaks piston stuck with flows to check filters valves. Specs for operating pressure impact rate energy class listed but not exhaustive. Parts list with exploded views for ordering but no pricing. No over-capitalization. Imperfections such as “includes wiring diagrams hydraulic layouts. torque specs listed for critical components but not all…” Solid manual for shop techs.
