PURPOSE: To eliminate the possibility of the occurrence of an erroneous work through a simple constitution, by a method wherein an indicator for indicating a tilt condition of a pressing blade is mounted to a position where it is observed from a driver's seat of a car body.
CONSTITUTION: A cover 5' is attached to a tilt cylinder 5, a pointer 7' is set to the cover 5' in the same direction as that of a cylinder 5, and it is caused to extend so that its point can be observed from a window in a side of a driver's seat. A neutral sign 9 is marked on the back of a press blade 2 in a position which the end of the pointer 7 indicates through the view from the side of the driver's seat when a tilt operating device is brought to a neutrality to keep a blade in a horizontal manner. Further, a right tilt sign 10a and a left tilt sign 10b are marked in positiones which the end of the pointer 7 indicates when the tilt operating device brings the press blade 2 into a right downward and a left downward tilt attitude, and an indicator consists of the pointer 7 and the signs 9, 10a, and 10b.
