1. A safety valve for a hydraulic or pneumatic tool, the safety valve comprising:
a body defining an incoming fluid passage via which fluid is able to pass from a fluid reservoir through the body to a tool head, and a return fluid passage via which fluid is able to return from the tool head through the body to the fluid reservoir;
a first position within the body, wherein the fluid is able to bypass the tool head and return to the fluid reservoir to prevent operation of the tool head, and at a second position within the body, wherein the fluid is able to flow to the tool head to allow operation of the tool head;
a biasing means operatively biasing to either a fail-safe position or a fail-dangerous position; and
an actuator positioned on an outside portion of the body, wherein the actuator is hand-operated and configured so that actuation thereof counteracts the biasing means and actuates the tool head into an inactive or active mode of operation.
