Maintenance & Inspection Information
The manual stresses that regular and correct maintenance is essential for maintaining the truck crane’s service life and operating condition. It highlights common maintenance-related problems such as insufficient oil, grease or antifreeze, contamination, rope damage, defective hydraulic or compressed-air systems, damaged hoses, loose connections, brake problems, defective tyres or wheel rims, and overdue maintenance intervals.
General maintenance instructions include cleaning service areas before maintenance, draining oil at operating temperature when changing oil, using only specified lubricants, replacing filters at the prescribed intervals, replacing seals before assembly, and depressurizing hydraulic systems before tightening connections. The manual also emphasizes keeping brake and clutch linings free from grease and replacing damaged hydraulic hoses.
Lubrication and Transmission Information
The supplied additional pages contain specific information concerning transmission oil for applicable GMK truck cranes. For the relevant transmission serial numbers, the document specifies a changed oil type and corresponding oil-change intervals. The additional information includes a maintenance schedule and lubricant table for the transmission.
The additional pages specify 11.0 litres (2.9 US gal.) for the transmission and identify lubricant designation F 7. The lubricant information references ZF TE-ML 02 / ZF-Ecofluid M3 and notes that the factory-filled synthetic oil should not be mixed with mineral oil.
Safety-Focused Maintenance Guidance
Safety is an important part of the manual. The warning symbols distinguish hazards that may result in personal injury, risks of damage to the truck crane or load, and environmental hazards associated with substances used during maintenance.
The manual also states that it is not a replacement for proper training and instruction and that maintenance personnel require appropriate specialist knowledge and safety procedures. Repair work is distinguished from routine maintenance and is intended for qualified repair personnel with suitable workshop equipment, special tools, and authorized replacement parts.
