4.2.4 NOTES REGARDING LUBRICATION
q
Lubrication makes the operations carried out with the machine and work equipment smoother, while preventing
wear and the noise that may be produced if the articulated joints are dry.
Lubrication is to be carried out with grease or oil.
q
The maintenance operations required for the components that need lubricating are the following:
1 - check of the levels;
2 - oil change;
3 - injection of grease through the grease nipples.
q
Use only the specified lubricants, according to the ambient temperature.
q
Always clean the grease nipples before injecting grease and remove any excess grease after lubrication; this
cleaning operation must be performed with extreme care on the revolving parts.
q
Keep the lubricants at the correct levels; excessive or insufficient quantities are to be avoided.
4.2.5 PARTS SUBJECT TO WEAR THAT PERIODICALLY NEED CHANGING
The parts subject to wear such as filters, bucket teeth, etc. must be replaced according to the periodic maintenan-
ce intervals prescribed or when they reach the wear limit.
The timely change of these parts ensures an economic use of the machine.
Use only Komatsu genuine parts, which alone can guarantee excellent quality and interchangeability.
