## Abstract

To accurately grasp a generation situation of a warning generated in an operation machine, the operation machine is provided with: warning generation means 55 adapted to determine whether or not there is abnormality, and in the case where there is abnormality, generate a warning; warning storage means 56 adapted to store warning information on the warning; display means adapted to display the warning information stored in the warning storage means 56; and warning erasing means adapted to erase the warning information, wherein the warning storage means 56 is configured to store warning information on a warning generated after the erasure by the warning erasing means 57.

## Claims

### Claim 1

An operation machine comprising:
a warning generation means configured to determine whether there is abnormality or not and to generate a warning when there is abnormality;
a warning storage means configured to store warning information on the warning;
a display means configured to display the warning information stored in the warning storage means; and
a warning pseudo erasing means configured to erase specified warning information of the warning information in a pseudo-erasing manner, the warning pseudo erasing means being configured to provide, after the warning information displayed by the display means is specified as the specified warning information, an instruction to make the specified warning information remain in the warning storage means and to make the display means not display the specified warning information.

### Claim 2 (depends on 1)

The operation machine according to claim 1, wherein
the warning pseudo erasing means includes:
a pseudo erasure time storage part configured to store a time when the warning pseudo erasing means performs the erasing in the pseudo-erasing manner.

### Claim 3 (depends on 1)

The operation machine according to claim 1, wherein
the warning pseudo erasing means includes:
a pseudo erasure specifying part configured to specify the warning information that is to be erased in the pseudo-erasing manner;
a flag setting part configured to set, to the specified warning information, a pseudo erasure flag indicating the specifying of performing the erasing in the pseudo-erasing manner, the specified warning information being specified by the pseudo erasure specifying part to be erased in the pseudo-erasing manner; and
a non-display instructing part configured to provide an instruction not to display, by the display means, the warning information being set with the pseudo erasure flag by the flag setting part.

### Claim 4

An operation machine comprising:
a warning generation means configured to determine whether there is abnormality or not and to generate a warning when there is abnormality;
a warning storage means configured to store warning information on the warning;
a display means configured to display the warning information stored in the warning storage means; and
a warning pseudo erasing means configured to erase the warning information in a pseudo-erasing manner, wherein
the warning pseudo erasing means includes:
a pseudo erasure specifying part configured to specify the warning information that is to be erased in the pseudo-erasing manner;
a flag setting part configured to set, to the warning information, a pseudo erasure flag indicating the specifying of performing the erasing in the pseudo-erasing manner, the warning information being specified by the pseudo erasure specifying part to be erased in the pseudo-erasing manner; and
a non-display instructing part configured to provide an instruction not to display, by the display means, the warning information being set with the pseudo erasure flag by the flag setting part.
