Checks after reassembly After reassembly, install the battery and then check component operations as follows: (1) Checking the direction of rotation Press the (R) side of Pushing Button (A) [32], and check that Drill Chuck 10MM [2] rotates in the clockwise direction (when viewed from the rear of the main body). (In case of reverse rotation, the soldered connections of the internal wires of Motor DC12V [28] and DC-Speed Control Switch [35] are inverse.) (2) Checking LED operation Turn the trigger of DC-Speed Control Switch [35] on and off, and check that the LED goes on and off. (The LED goes on when the trigger is turned on; the LED goes off when the trigger is turned off.) (3) Checking shift knob operation Set Shift Knob [33] to "HIGH" (high-speed rotation) and "LOW" (low-speed rotation), and check that rotation speed is switched correctly without any abnormal noise being generated by the gears or other parts.
