3.201 USAGE NOTE

Note that when the base form of 'try' is used, for example as an imperative or with a modal, it is sometimes used with 'and' followed by the base form of the second verb, rather than with a 'to'-infinitive. The two actions seem to be separate, because of the 'and', but are in fact very closely linked.

Some speakers consider this to be informal or incorrect.

'Come' and 'go' are often used in a similar way with 'and', in simple tenses as well as in the base form. The verb after 'and' can also inflect.
