To set the handymen priorities, just click on them. In the window you'll see 3 icons, 1 for sweeping litter, 1 for watering the plants, and 1 for fixing machinery. When you click the progress bar under the icon will move, the more its full, the more the handyman will do this task.
When you move the mouse cursor over a machine that can be repaired, you can see the actual strenght in the right bottom corner of the screen. If you click on a machine, you can manually tell a handyman to repair it, and you can also replace the machine with a new one. Strenght decreases as the machine is used, as well as the status on the machine. When a handyman repair a machine, the status is restored, but the strenght will not be.
