Try to ... and try -ing
Try to do = attempt to do, make an effort to do:

If
try (with this meaning) is followed by a verb, we say
try -
ing:
- A: The photocopier doesn't seem to be working.
B: Try pressing the green button.
(= press the green button - perhaps this will help to solve the problem)
Compare:
