Näsinneula

The morning of the amusement park has started off in catastrophic moods. Machine operators who arrived at work have reported several amusement park rides that refuse to start. Most of the park's rides seem to be out of order, even though they all worked last night! The amusement park's maintenance guy should be able to explain what the problem is, but he hasn't been seen all morning. The guy seems to have disappeared like dust in the wind. Pirkko who arrived for the morning shift at the hot dog booth can only hint that the maintenance man has been seen often near the Näsinneula, and especially its elevator. Just last night, the maintenance man was seen stepping into the elevator. Could there be any clues there..? Can you figure out what happened to the maintenance guy and get the rides up and running before the first customers arrive?
