And a new group storage unit 3a34 for storing new group parts processed by the registration processing unit 3f described above.

  For example, as shown in FIG. 3, the above-described all parts storage unit 3a1 stores parts in which display priorities are set in advance and maintenance time in association with each other. It is stored that the front pin lubrication with the highest priority is currently in a state where the service life has exceeded the 10-hour service life even though the service life is 500 hr (hours). Further, it is stored that the engine oil of the third highest priority has a service life of 500 hours, but the remaining time is only 5 hours. Therefore, these are parts that are considered to have reached the maintenance time. For other parts as well, the service life and remaining time are stored in the maintenance time section together with the display priority.

  Further, as shown in FIG. 4, for example, four selected parts “front greasing”, “suspension pin greasing”, “engine oil”, and “engine oil filter” are respectively stored in the selected part storage unit 3 a 2 described above. It is stored with the display priority. Further, in correspondence with each part, the service life and the remaining time or the excess time are stored in the maintenance time section.

  Further, in the group selection part storage unit 3a3 described above, for example, as the traveling relation storage unit 3a31, as shown in FIG. 5, there are four group selection parts "Suspension pin greasing", "Engine oil", "Engine oil filter" "Radiator water" is stored together with the display priority order. Further, the service life and remaining time or excess time are stored in the maintenance time section in correspondence with each part.

  The remaining time and the excess time for determining the maintenance time shown in FIGS. 3 to 5 are calculated, for example, every 5 hours from the accumulated operating time of the hydraulic excavator measured by the operating time timer 3b and the service life of each part. Calculated by means 3c. The calculation result is immediately rewritten as the remaining time and the excess time in the term “maintenance time” in each of the storage units 3a1 to 3a3.
