Maintenance and repairs
12 Tips and hints
Regular and proper servicing and inspection are essential for the faultless operation and long service life
of your excavator. Preventative Maintenance is the simplest and cheapest method of servicing.
12.1 Maintenance
– The engine must be stopped before all service and repair work. Protective devices for moving
machine parts must only be opened or removed when the machine is shut down. At the same time
it must be ensured that the engine cannot be put into operation by unauthorized persons. Only tilt
cab with the cabin door closed. The cabin must be mechanically secured in the tilted state (danger
of accident).
– Defective parts must be promptly replaced to avoid greater damage.
– After using the excavator on an extensive scale, it must be thoroughly cleaned.
– To pevent corrosion damage, regularly grease all exposed parts.
– After completion of maintenance and repair work, put all protective devices properly back again.
– See to the tightness of all bolt connection as well as to leaks in the hydraulic system.
– Pay special attention to correctly tighten nut and bolts. Check and retighten wheel-nuts regularly.
– If there is any visible loss of oil, determine the cause and remedy the fault.
– Retighten hydraulic connections in the event of leaks.
– Replace damaged pipes and hoses immediately with new ones.
– Check machine for cracks and reweld, if necessary.
– Pay attention to the lubrication schedule and to the maintenance work of the Perkins engine.
– Thoroughly clean grease fittings before greasing.
– Change oil only when machine is operationally warm, as warm oil runs off better.
– All filters are carefully adapted to the machine. Trouble-free operation and long service life of the en-
gine and the hydraulic parts can only be achieved if original parts are used.
– Use only original parts. This ensures a trouble-free operation and a long lifetime. Menzi Muck AG on-

– Do not mix different brands of lubricants with one another, as the quality is possibly influenced by
this. Lubricate according to the maintenance schedule indicated in the lubricating instructions.
Environmental protection provisions must be observed when removing operation materials (i.e., oil,
grease, fuel) etc. from oily components, such as filters.
– 500 hour service only by authorized workshops.
