if there are two other, smaller levers, one probably activates a starting clutch. Pulling that will engage a small clutch that connects the pedals to the engine. Then you'd pedal and the engine turns and (hopefully) starts. Immediately disengage that lever after it starts.
Another lever may go to a decompression valve in the head. This valve releases presure in the cylinder.. it's a vent.
Venting all cylinder pressure makes it very easy to pedal-start the engine. Many people don't need this assistance but some do. Again, as soon and the engine starts up this lever is released and the vent-valve closes.
Follow the cables leading from all those levers. If they go to the engine block and to the head, it's most likely the above is their function.
Hang around for some Hero experts to notice your question. As far as getting hold of a manual you really should find one somehow..
I dunno how familiar you are with mopeds or 2-stroke engines in general but they do require some particularly important preparation before riding, like 2-stroke oil must be somehow mixed in with the fuel. Some bikes do this automatically with a pump and oil resevoir, or oil is pre-mixed with gasoline manually.
