A lapping tool for lapping a wafer section in a well controlled manner, has a head with an actuator for bending the row tool, and a force multiplier coupled between the actuator and row tool to multiply the force generated by the actuator for application of greater bending force to the row tool than can be generated by the actuator. The operations management system provides a standardized environment for providing feedback to a vendor of components installed at the customer data centers. The user exchangeable cover part comprises identification means. Based on the descriptive schemas that specify required inputs and outputs of the web services and web-based applets, combinations of web services and web-based applets are generated. Operation of the assembly results in movement of the first needle valve element to an open position for throttling fuel flow through the throttle passage followed by subsequent lifting of the second needle valve element for longer duration injections. By operating in this manner, the present invention may allow a worker to position the arm in any number of different and easily attainable positions while also allowing the worker to secure a workpiece and immobilize the arm in a single step.
