PURPOSE:To adjust the phase of a working machine by connecting both-side chambers of a starting cylinder through a valve in the limiting position of the starting cylinder to detect the actions of the contracted model machine of a working machine. CONSTITUTION:When the handle 12 of a contracted model machine at an operator's cabine is turned to the left, the piston of a starting cylinder 32 is moved to the right, a switch valve 30 is moved to the left, pressure oil from a pump P enters a power cylinder 11, a bucket link 8A is turned to the left, and the bucket is turned by as much as rotational amounts equal to the rotational amount of the handle 12. In adjusting the positions, the bucket is stopped at the limiting position of clockwise rotation, the valve 36 is opened, the handle 12 is stopped at the limiting position of clockwise rotation, and oil from a tank T is replenished to the right-handed chamber of the starting cylinder through a suction valve 37. |
