Abstract
A hand tool for opening and holding a check valve in an open position to release hydraulic fluid in a hose. One lever has a yoke with a pair of ears accommodating a portion of the hose to locate the coupling in a pocket formed by a U-shaped collar mounted on the other lever. A finger located in the pocket of the U-shaped collar engages the check valve and holds the check valve in an open position to release the pressure of the fluid in the check valve assembly and hose. The operator is shielded from the fluid flowing from the check valve by the generally U-shaped collar.
