'Loslegen' (to get started) is a separable verb. The prefix 'los-' goes at the end in a main clause. In subordinate clauses or when used with a modal verb, the verb stays together.
Nach einer kurzen Pause legten die Arbeiter wieder los.
After a short break, the workers got started again.
The prefix 'los-' often signals the beginning of an action, as in 'losfahren' (to set off by vehicle) or 'losgehen' (to set off / begin). In 'loslegen' (to get started), it combines with 'legen' (to lay/put) and creates the energetic meaning of starting.
Sobald der Startschuss fiel, legten die Läufer los.
As soon as the starting signal was given, the runners got started.
This verb clearly belongs to informal speech. It sounds dynamic and casual and fits well in everyday conversations, but less so in formal or written contexts.
Na los, leg schon los, wir haben nicht den ganzen Tag Zeit!
Come on, get started already, we don't have all day!
If you want to say exactly which activity is beginning, use the preposition 'mit' followed by a noun in the dative.

This weekend, I finally want to get started with painting the walls.
