MAINTENANCE BASICS SPARE PARTS AND CONSUMABLE COMPONENTS Replace parts which are subjected to wear and tear, such as filter elements, air filter insert, etc., when performing the reg- ular maintenance work or when the limiting value for wear and tear and contamination is reached. Perform this work at regular intervals and as prescribed to ensure an efficient use of the machine. Only use original Komatsu spare parts. After removing the gaskets, clean the sealing surfaces. Re- place gaskets and O-rings with new ones. Pay attention not to forget any gaskets and O-rings when re-assembling the parts. Use the part numbers specified in the spare parts catalogue for ordering of spare parts.
