papa lalo

Thanx guys. I will check all.

Ive just assembled the arocs mercedez truck. Wow its big but the pnematics dont work at all. Pumps on, slight movement but not enough power to lift anything. How does one know if the pump is putting out or mal functuioning or valve mal functioning. Im frustrated a bit. Seems at best the pneumatics system is weak to begin with. Do the little blue pumps often cause trouble. It is a new set. Thanx
