9.01 General remarks on maintenance and maintenance work
Steps must be taken to ensure that all safety regulations are adhered to in the execution of maintenance work!
Careful machine maintenance guarantees far greater functional reliability and increases the life of all important components. The necessary input is minimal in relation to the faults and problems which can occur as a result of failure to perform maintenance work.
•The engine and machine must be thoroughly cleaned before performing any maintenance work.
•Maintenance work may only be performed when the engine is at a standstill.
•When working with the hydraulic system, this must fi rst be depressurised.
•Before working on the electrical system, detach the battery, cover it and protect with insulating material.
•Check the electrical equipment of the machine at regular intervals. Defects such as loose connections or melted cables must be remedied immediately and replaced by new ones.
•Only carry out maintenance and repair work when the machine is positioned on an even surface capable of bearing loads and safeguarded against rolling away.
•Adhere to the prescribed maintenance and inspection procedures in the operating instructions, including instructions in the exchange of parts. This work may only be performed by specialised personnel.
•Oil and fuels must not be permitted to seep into the ground or sewage system during maintenance work. These must be collected using suitable means and disposed of in an environmentally responsible manner!
Remarks on the hydraulic system:
Avoid dirt or other contaminants entering the hydraulic system. Even the smallest dirt particles in the hydraulic pipework can lead to tremendous impairment to hydraulic units and so to costly repairs.
•Should it be discovered during the daily check of the hydraulic oil level that the oil level is sinking, the complete hydraulic pipework must be checked immediately for leaks.
•Leaks must be repaired immediately. If necessary, inform the responsible
•If possible fi ll the hydraulic system with fi lling aggregate.
•Clean screw joints, the fi lling cap and its surroundings before removal to prevent the ingress of dirt particles.
•Do not leave the tank cap open unnecessarily to prevent foreign bodies entering the system.
9.02 Running in regulations
Maintenance after 25 hours of operation:
•Check all screw connections and tighten if necessary.
•Check hydraulic hoses and the complete hydraulic oil system for leaks.
•Replace the fuel fi lter. (Fig. 18, section 9.7)
•Engine : See maintenance instructions Hatz 2G40!
