Bonus not cleared entirely, can I withdraw some of the initial deposit

[Stosh]

Please excuse me if this is a stupid question, I am pretty new to the world of bonus whoring. I recently signed up at Absolute and deposited $600 to get the max on the 35% initial deposit. I've cleared about half of it so far, but would like to withdraw maybe $250 or so back to my Neteller account. Would this kill the rest of my potential bonus? Thanks for the help. 'Stosh
