Abstract

PURPOSE:To lengthen the life of a hydraulic machine and to lessen the burden on an operator by sequentially driving a prime mover and a hydraulic pump in a designated state to automatically conduct warming-up operation when a key switch is switched to a starting position. CONSTITUTION:Outputs from a key switch 5, an oil temperature detector 9 and a water temperature detector 8 for detecting the temperature of cooling water of a prime mover 1 are input to a control portion. When the key switch 5 is switched to a starting position, a tilting angle of a swash plate 2a is decreased and a signal is output to a governor 1a to force the prime mover 1 to idle, thereby warming-up the prime mover 1. When the temperature of cooling water becomes above a set temperature, the prime mover 1 is rotated at medium speed and the swash plate 2a is tilted at the maximum to warm up a hydraulic pump 2. Accordingly, warming-up can be automatically performed, so that the life of a hydraulic machine can be lengthened and the burden on an operator can be lessened.
