641 Hydraulics

When I park my 641 for a few days or longer my hydraulic system seems to lose it's prime and won't lift. The only way I can make it work is to blow compressed air into the hydraulic dipstick hole and then put the dipstick back in real fast. Once I do this the hydraulics seem to have plenty of power and works fine. Any thoughts?
