A method for calibrating a power tool having a roller, a driver and a solenoid. The solenoid has a body and a rod and is coupled to the roller so as to be capable of selectively advancing the roller toward the driver. The method includes: locating the roller onto a predetermined portion of the driver; moving the body of the solenoid in a first direction until the occurrence of a first predetermined condition, the first direction being in a direction that causes the roller to be driven toward the driver; after the occurrence of the first predetermined condition, moving the body of the solenoid in a second direction opposite the first direction until the occurrence of a second predetermined condition and thereafter securing the body of the solenoid to inhibit further movement of the body of the solenoid.

What is claimed is: 1. A method for calibrating a power tool having a structural backbone, a flywheel mounted on the structural backbone, a driver, an activation arm, which includes an arm that is pivotally coupled to the structural backbone and a roller that is supported by the arm, a cam and a solenoid with a body and a rod that is coupled to the cam, the method comprising: locating the roller onto a predetermined portion of the driver; moving the body of the solenoid in a first direction until the occurrence of a first predetermined condition, the first direction being in a direction that causes the roller to be driven toward the driver; and after the occurrence of the first predetermined condition, moving the body of the solenoid in a second direction opposite the first direction until the occurrence of a second predetermined condition and thereafter coupling the body of the solenoid to the structural backbone. 2. The method of claim 1, wherein the driver includes a cam profile with a first cam portion, a second cam portion and at least one generally flat rail disposed between the first and second cam portions, and wherein the predetermined portion of the driver is the at least one generally flat rail. 3. The method of claim 1, wherein the first predetermined condition is a positioned-based condition. 4. The method of claim 3, wherein the position-based condition is a condition where clearance between each of a plurality of components that mechanically link the rod of the solenoid and the roller is eliminated. 5. The method of claim 3, wherein the rod of the solenoid and the roller are a portion of a drive-line that is selectively employed to engage the driver to the flywheel and wherein the position-based condition is a condition where the driver is engaged to the flywheel, the roller is engaged to the driver and no clearance exists between each adjacent pair of the plurality of components that form the drive-line. 6. The method of claim 1, wherein the first predetermined condition is related to an amount of force that is applied to the body of the solenoid. 7. The method of claim 1, wherein the second predetermined condition is an amount by which the body of the solenoid has been moved in the second direction relative to a predetermined point. 8. The method of claim 7, wherein the predetermined point is a point at which the first predetermined condition occurred. 9. The method of claim 1, wherein prior to moving the body of the solenoid in the first direction a tool is engaged to the body of the solenoid. 10. A method for calibrating a power tool having a roller, a driver and a solenoid with a body and a rod, the solenoid being coupled to the roller and operable for selectively advancing the roller toward the driver, the method comprising: locating the roller onto a predetermined portion of the driver; moving the body of the solenoid in a first direction until the occurrence of a first predetermined condition, the first direction being in a direction that causes the roller to be driven toward the driver; and after the occurrence of the first predetermined condition, moving the body of the solenoid in a second direction opposite the first direction until the occurrence of a second predetermined condition and thereafter securing the body of the solenoid to inhibit further movement of the body of the solenoid. 11. The method of claim 10, wherein the driver includes a cam profile with a first cam portion, a second cam portion and at least one generally flat rail disposed between the first and second cam portions, and wherein the predetermined portion of the driver is the at least one generally flat rail. 12. The method of claim 10, wherein the first predetermined condition is a positioned-based condition. 13. The method of claim 12, wherein the position-based condition is a condition where clearance between each of a plurality of components that mechanically link the rod of the solenoid and the roller is eliminated. 14. The method of claim 12, wherein the rod of the solenoid and the roller are a portion of a drive-line that is selectively employed to engage the driver to a flywheel and wherein the position-based condition is a condition where the driver is engaged to the flywheel, the roller is engaged to the driver and no clearance exists between each adjacent pair of the plurality of components that form the drive-line. 15. The method of claim 10, wherein the first predetermined condition is related to an amount of force that is applied to the body of the solenoid. 16. The method of claim 10, wherein the second predetermined condition is an amount by which the body of the solenoid has been moved in the second direction relative to a predetermined point. 17. The method of claim 16, wherein the predetermined point is a point at which the first predetermined condition occurred. 18. The method of claim 10, wherein prior to moving the body of the solenoid in the first direction a tool is engaged to the body of the solenoid. 19. A method of calibrating a power tool having a structural backbone, a flywheel mounted on the structural backbone, a driver, an activation arm, which includes an arm that is pivotally coupled to the structural backbone and a roller that is supported by the arm, a cam and a solenoid with a body and a rod that is coupled to the cam, the rod of the solenoid and the roller being a portion of a drive-line that is selectively employed to engage the driver to the flywheel, the method comprising: locating the roller onto a predetermined portion of the driver; placing a member of a predetermined thickness between the roller and the predetermined portion of the driver; moving the body of the solenoid in a first direction until the occurrence of a predetermined condition, predetermined condition being a condition where the driver is engaged to the flywheel, the roller is engaged to the driver and no clearance exists between each adjacent pair of the plurality of components that form the drive-line; and coupling the body of the solenoid to the structural backbone.
