a body including a first surface; a back portion including: a second surface at a second end of the hydraulic tool that is opposite the first end; a third surface that is between the first surface and the second surface, where the third surface is inclined with respect to the first surface and the second surface; an indicator light; and a window, at least a portion of which is positioned on the third surface, where the window covers the indicator light; and a grip that extends from the body away from the first surface. ## Claims ### Claim 1 A hydraulic tool comprising: a head at a first end of the hydraulic tool, the head configured to apply a mechanical force to a work piece; a body comprising a first surface; a back portion comprising: a second surface at a second end of the hydraulic tool that is opposite the first end; a third surface that is between the first surface and the second surface, the third surface inclined with respect to the first surface and the second surface, the third surface including a first portion that abuts the second surface, the third surface including a second portion that abuts the first surface; an indicator light; and a window, at least a portion of the window being positioned on the third surface, the window overlapping the first portion and the second portion of the third surface, the window covering the indicator light; and a grip that extends from the body away from the first surface. ### Claim 2 (depends on 1) The hydraulic tool of claim 1, wherein the head is configured to crimp the work piece. ### Claim 3 (depends on 1) The hydraulic tool of claim 1, wherein the head is configured to cut the work piece. ### Claim 4 (depends on 1) The hydraulic tool of claim 1, wherein the head is configured to shear the work piece. ### Claim 5 (depends on 1) The hydraulic tool of claim 1, wherein the head is configured to be hydraulically actuated. ### Claim 6 (depends on 1) The hydraulic tool of claim 1, wherein the first surface is parallel to a longitudinal axis of the hydraulic tool. ### Claim 7 (depends on 1) The hydraulic tool of claim 1, wherein the second surface is perpendicular to a longitudinal axis of the hydraulic tool. ### Claim 8 (depends on 1) The hydraulic tool of claim 1, wherein the window is elongated in a direction that is substantially perpendicular to a boundary that separates the first portion from the second portion. ### Claim 9 (depends on 1) The hydraulic tool of claim 1, wherein the window is rounded such that it conforms to the second surface, the first portion, and the second portion. ### Claim 10 (depends on 1) The hydraulic tool of claim 1, wherein the window is elongated in a direction that is substantially parallel to a boundary that separates the first portion from the second portion. ### Claim 11 (depends on 10) The hydraulic tool of claim 10, wherein the window is rounded such that it conforms to the first portion and the second portion. ### Claim 12 (depends on 1) The hydraulic tool of claim 1, wherein the hydraulic tool is configured to: make a first determination that a cutting, crimping, or shearing operation that satisfies a predetermined criterion has been performed on the work piece by the head; and cause the indicator light to emit a first light that corresponds to the first determination. ### Claim 13 (depends on 1) The hydraulic tool of claim 1, wherein the hydraulic tool is configured to: make a second determination that a cutting, crimping, or shearing operation that satisfies a predetermined criterion has not been performed on the work piece by the head; and cause the indicator light to emit a second light that corresponds to the second determination. ### Claim 14 (depends on 1) The hydraulic tool of claim 1, wherein the grip is a pistol grip. ### Claim 15 (depends on 1) The hydraulic tool of claim 1, the grip comprising a first actuator that, when activated, causes the head to close upon the work piece. ### Claim 16 (depends on 1) The hydraulic tool of claim 1, the grip comprising a second actuator that, when activated, causes the head to open away from the work piece. ### Claim 17 A hydraulic tool comprising: a head at a first end of the hydraulic tool, the head configured to apply a mechanical force to a work piece; a body comprising a first surface; a back portion comprising: a second surface at a second end of the hydraulic tool that is opposite the first end; a third surface between the first surface and the second surface, the third surface inclined with respect to the first surface and the second surface; an indicator light; a window, at least a portion of the window being positioned on the third surface, the window covering the indicator light; a grip that extends from the body away from the first surface; and an adjustable loop attached to the back portion. ### Claim 18 (depends on 17) The hydraulic tool of claim 17, wherein in a retracted position, the adjustable loop is between the head and the second surface. ### Claim 19 (depends on 17) The hydraulic tool of claim 17, wherein in an extended position, the adjustable loop extends beyond the second surface. ### Claim 20 (depends on 17) The hydraulic tool of claim 17, wherein in an upright position, the adjustable loop is between the head and the second surface. ### Claim 21 A method of operating a hydraulic tool to apply a mechanical force to a work piece, the method comprising: positioning the work piece within a head; activating a first actuator of the hydraulic tool, causing the head to close upon the work piece; making a first determination that a cutting, crimping, or shearing operation that satisfies a predetermined criterion has been performed on the work piece by the head; causing an indicator light to emit a light that corresponds to the first determination; making a second determination that a cutting, crimping, or shearing operation that satisfies the predetermined criterion has not been performed on the work piece by the head; and causing an indicator light to emit a light that corresponds to the second determination. ### Claim 22 (depends on 21) The method of claim 21, wherein making the first determination and making the second determination further comprises determining that a pressure that has been applied by the head upon the work piece exceeds a threshold pressure. ### Claim 23 (depends on 21) The method of claim 21, wherein making the first determination and making the second determination further comprises determining that a distance between jaws of the head is less than a threshold distance.
