There are two ways to run the Linter. The first is the command line with the -lint option in synth_design :
synth_design -top <top_level> -part <part> -lint
The second way is with the IDE. In the RTL ANALYSIS section of the Project Manager, there is a Run Linter button that will run the Linter with the current part and top level.

Note: The RTL linter currently does not work on OOC modules.
This will be supported in a later release.
