Fluid-powered torque wrench with fluid pump controls

A tool comprising:

• a housing;
• a drive mechanism supported by the housing, the drive mechanism being selectively- driven by a fluid pump and operable to drive an output member;
• and
• a control assembly including:
• a handle assembly removably connectable to the housing and including a first handle portion and a second handle portion, wherein the second handle portion is positionable in a first position when the handle assembly is connected to the housing and in a second position relative to the first handle portion when the handle assembly is connected to the housing;
• and
• pump controls supported by the handle assembly and removably connectable to the housing therewith, wherein the pump controls are operable to control the pump to drive the drive mechanism and thereby the output member, the pump controls being in communication with the pump:
• a first pump control supported proximate the first handle portion, the first pump control being operable by a digit of a first hand of an operator gripping the first handle portion;
• and
• a second pump control supported proximate the second handle portion, the second pump control being operable by a digit of a second hand of the operator on the second handle portion;
• wherein operation of the pump requires the operator's first hand on the first handle portion and the operator's second hand on the second handle portion;
• and
• wherein the pump is operable under the control of the pump controls to drive the drive mechanism when the handle assembly is connected to the housing and when the handle assembly is disconnected from the housing.

A method of operating a fluid-operated tool, the tool including a housing and a drive mechanism supported by the housing and operable to drive an output member, the method comprising:

• providing a control assembly including a handle assembly separate from the housing, the handle assembly including a first handle portion, a second handle portion, and at least one pump control, the first handle portion and the second handle portion being movably coupled together;
• moving the second handle portion from being coupled to the first handle portion in a first position relative thereto to being coupled in a second position relatively thereto;
• selectively and alternatively releasably connecting the handle assembly to the housing and disconnecting the handle assembly from the housing;
• positioning the output member relative to a fastener to be adjusted;
• when the handle assembly is connected to the housing, after positioning, operating a fluid pump to drive the drive mechanism and thereby the output member, operating including sensing an operator's first hand on the first handle portion while sensing the operator's second hand on the second handle portion, wherein sensing the operator's first hand or the operator's second hand is provided at least in part via the pump control;
• and
• when the handle assembly is disconnected from the housing, after positioning, operating the fluid pump to drive the drive mechanism and thereby the output member, operating including sensing the operator's first hand on the first handle portion while sensing the operator's second hand on the second handle portion.
