INJURY FROM EXTREME HYDRAULIC OIL PRESSURE. WHEN DE-PRESSURIZING

CYLINDERS IT IS IMPORTANT TO MAKE SURE NO HYDRAULIC OIL CAN BE

SPRAYED. MAKE SURE THAT NO PERSONNEL ARE STANDING NEAR THE

Not all manifolds are mounted on manifold blocks and the number of o-rings required can

be determined when the counterbalance manifold is removed.
