P40 Neck adjustment - in dire need of help.

[RoBc]

Hello all, I am in need of advice and as I am new to the parker world please assist.

My parker P40 has a bow (not too severe, but it does cause the string action to be fairly high) in the neck and as I am low on money I was considering doing the adjustment myself, but I dont want to damage my beautiful parker.
If it is a viable option to do it myself please can you help by telling me what exactly I sould be doing eg which direction etc.

Thanks for all your help it is much appreciated.
