A system comprises a detector for engine operation (1), a multi-display (2), time-checking switches (2,4), a set switch (5), a cancel switch (6), filter clopping sensors (7,8,9), a printer (10), an input/output port (11), a CPU (12), a ROM (13), a RAM (14) and an EEPROM (15). The ROM (13) stores recommended replacement time for each object, including various oils and filters, from which measured engine operation time is deduced. When it gives a negative value, a replacement request is displayed so that an operator can replace the required object. |
