Default problem with a graco gh200 hydraulic sprayer

Hi guys .I own a graco gh 200 (I bought used, but on good condition, the guy
that sold it to me just used few times, there is not leak ).on friday was my second time using it (I used different small machines before).on friday the hydraulic pump stopped working.on the manual says:if the engine operates, but displacement pump doesn't operate.I think these are the only 2 posible options :
Hydraulic pump damage
Hdraulic motor is not shifting .turn the valve OFF. Turn pressure down. Turn engine OFF. Pry rod up or down until hydraulic motor shifts (how do you do this , the hydraulic rod?)
the oil level is good, the filter is clean
i was spraying rhino shield paint(elastosmeric, ceramic paint)i took the 2 filters off)
What do you guys think?
thanks
